Tyco safeguards Romanian Carrefour

Tyco safeguards Romanian Carrefour

Editor / Provider: Tyco | Updated: 1/3/2014 | Article type: Commercial Markets

When Carrefour expanded its presence of hypermarkets across 3 continents, they hired security system integrator UTI to establish loss prevention systems within their unique shopping environment. The security company met the challenge, equipped with state-of-the-art video surveillance equipment from American Dynamics and successfully improved Carrefour's security.

A hypermarket like Carrefours is essentially a super-sized supermarket that typically stocks some 70,000 items and has a sales floor as big as 20,000 square meters or approximately 215,000 square feet. But as of 1999, no one in Romania had yet seen a hypermarket — at least not on their home turf. Carrefour executives noticed the void, and devised a plan: open 2 hypermarkets a year in every Romanian city.

A crucial part of any retail endeavor is loss prevention. Shoplifting and employee theft or internal shrinkage can take a balance sheet from black to re. According to Jack Hayes, who conducts an annual retail theft survey, these are serious crimes that not only take a toll on retailers' bottom-line profits but also “hurt our economy, costing consumers higher prices at the cash register, and causing a loss of jobs when retailers are forced to close stores or even go out of business.” Unfortunately, this problem appears to be especially severe in Romania.

Seizing the Opportunity — and Securing It
“Because Romania is so far from our home base in France, I wanted to make sure that if there was a problem, someone would be there to fix it,” he said. Luckily, about this time, UTI Retail Solutions' Managing Director Simona Dinca heard about Carrefour's plans to enter Romania. She called to see if they could help.

Tyco Fire & Security's distributor for the region, UTI's had the technology to address security issues unique to the mega-sized hypermarket. Besson tested the products in their showroom and was impressed with the quality and performance. Very soon Dinca assembled a team and together they set about designing a security system tailored to hypermarket specifications.

Rolling It Out
The first store, Carrefour Militari, located in Bucharest, was slated to break ground in 2000 and would feature a sales floor of 10,500 square meters stocked with 50,000 products. That's a lot to keep an eye on, especially considering the unprecedented temptation such a vast selection of goods posed to the potential shoplifter who was unaccustomed to a market economy.

The UTI team addressed the challenge with 2 SensorRail video systems, 18 SpeedDomeR Ultra IV programmable dome cameras, 4 SpeedDome Optima programmable dome cameras, multiplexers, analog video recorders, and a VM96 matrix switcher system . All are from American Dynamics, part of Tyco Fire & Security's Access Control and Video Systems business unit.

After the installation, Besson had full video coverage of everything— from the commercial areas to the warehouses—just as he had requested. Moreover, The SensorRail, in particular, gives security staff a vantage point over all of the hypermarket's enormous display aisles. It's ideal for warehouses or high-ceilingedbuildings like a hypermarket, serving as a motorized perch for domes that noiselessly move along its tracks the same way a train does, only inverted, to close in on wherever the action is. “The SensorRail enhances the roving perspective that the SpeedDome Optimas offer,” said Viorel Luta, UTI's technical manager for the project. “Combined, they expand your ability to cover broad expanses of retail space far beyond what you can manage with a dome camera by itself.”

In addition, American Dynamics' IntellexR Digital Video Management System and Network Client had also been installed. Intellex enables Besson and his security personnel to establish a perimeter around certain areas, such as the place where employees make cash drops, so that anyone who crosses into these areas triggers an alarm. They can set alarms to go off based on the speed, direction, or size of an object in motion as well. For instance, someone entering the hypermarket through an exit door could trigger an alarm that would appear on the monitor screen.

On the other hand, Network Client grants Besson and his staff remote access to the system. As further protection against shoplifting, UTI outfitted the cash registers and entrances at all Carrefour stores with Acousto Magnetic Electronic Article Surveillance (EAS). EAS systems help curb shoplifting by tying together electronic article surveillance, video, and point-of-sale systems, and delivering real-time intelligence to the store or corporate office.

A Wholesale Success
The security installation at Carrefour Militari alone paid for itself in the recovery of stolen merchandise within 18 months, helping them catch an average of 10 wannabe shoplifters daily. And now, Carrefour has 4 hypermarkets in Romania.

“We're enormously pleased with how well our high tech surveillance equipment is performing,” said Besson. As he and his staff have found, it does more than stop shoplifters. Stores remain open as late as 10 p.m. and the surveillance cameras outside have helped deter car theft and acts of violence that are more prone to happen at night.

HD-SDI(8): Benefits of HD-SDI

HD-SDI(8): Benefits of HD-SDI

Editor / Provider: Alf Chang | Updated: 12/20/2013 | Article type: Hot Topics

Serial digital interface (SDI) is a family of digital video interfaces. There are 3 types of SDI standards: SD-SDI, HD-SDI and 3G-SDI. SD-SDI is defined for standard definition digital signals, while HD-SDI and 3G-SDI are for HD video signals. Among them, the most popular adoption in security and surveillance industry is HD-SDI.  See more products here.

HD-SDI solutions all employ coaxial cables with BNC connectors to transmit processed digital signals. For this reason, many installers and customers may misunderstand HD-SDI to be a high resolution analog solution. However, HD-SDI belongs to the digital video category. Here are some of its benefits:

Re-cabling unnecessary
BNC connectors allow easy installation of HD-SDI without any significant modification of existing analog cabling. Meaning, when upgrading from existing system to HD-SDI, only front-end and back-end products need to be replaced. This approach increases time efficiency while cutting labor costs.

Easy Knowledge transfer
Since HD-SDI adopts the same infrastructure with analog systems where coaxial cables are largely deployed, installers and operators can quickly adapt to the new technology and ensure quick and correct installations.

Latency-free HD image
HD-SDI signals are transported in latency-free and uncompressed digital signals over coaxial cables, plus crystal-clear HD images. HD-SDI solution is able to meet the demands of real-time monitoring without any latency caused by network issues.

Cost-effective utilization of devices
HD-SDI outputs images of 1920×1080 resolution. Hence, the number of cameras needed to capture vivid details such as facial features or license plate is largely reduced.

Project scale makes the difference
Small-scale HD-SDI systems require fewer cameras. These systems can be directly upgraded from analog to HD-SDI; therefore, installers can simply replace front-end products.  

For middle- to large-scale HD-SDI systems with numerous cameras and bigger storage requirement, installers can adopt HD-SDI video encoders to compress front-end HD-SDI signals into H.264 digital signals and transmit to IP storage area networks (SANs).

Users may question why HD-SDI signals still need to be digitalized. This is because when integrating SDI and IP systems, the front-end HD-SDI real-time video streams are captured into a video encoder, then the converted digital signals are distributed to a video matrix switcher for real-time monitoring. The signals are then further sent to an encoder for storing. This approach ensures HD rendition in monitoring and storing.

Some prerequisites include:

Analog camera installations are different from HD-SDI camera installations. While bad connections or false linkage of connectors in analog systems simply cause horizontal strips or jitters on the video, HD-SDI camera installations, on the other hand, cannot stand any false connections because the video will be lost. Analog video signal frequency is in waveforms whereas HD-SDI signal frequency looks like serrated edges.

Some installers tend to cut off BNC connectors of video cables, however; this can seriously weaken the HD-SDI video outputs.

Currently, HD-SDI supports a limited transmission distance of 100 meters on regular video coaxial cables. Distance larger than 100 meters can result in less stable transmission. For a longer distance, installers are suggested to use fiber optic to ensure video quality and reliability.

Output Conversion
When HD-SDI video signals are converted and transported via High-Definition Multimedia Interface (HDMI) signals, low quality of HDMI cables may significantly disrupt these video signals. The proven and tested distance limitation is 20 meters, but video signals would be weakened after 15 meters on HDMI.

HD-SDI solutions incorporate signal amplifiers to boost the signal transmission distances. However, different brands of front-end signal sources may have compatibility issues that may possibly block signal outputs. Currently, dedicated HD-SDI monitors are more expensive and rarely used in surveillance installations. The most cost-efficient display option is HDTVs with HDMI support. The drawback for this is that different brands of HDTVs have different predefined settings of video signal inputs, which cause the compatibility issues among individual brands of HD-SDI video sources. This may result a prompt indicating “unsupported format” in operations.  

These mentioned issues seem to be the limitations of HD-SDI solutions. However, with careful product investigations and tests before implementations, a successful upgrade to HD solutions can be carried out. HD-SDI continues to evolve in the security industry and flourishes in the market with its unique advantages.

HD-SDI(4): Revolution of HD-SDI matrix systems

Editor / Provider: Alf Chang | Updated: 12/6/2013 | Article type: Hot Topics

HD-SDI matrix switcher evolved beyond the standard definition SDI matrix. The differences and advantages from analog matrix are highlighted.

Digital video transmission for analog systems is one of the most important issues for upgrading legacy systems. Matrix switchers route multiple audio and video sources to multiple audio and video destinations.

Featuring BNC connectors, SDI matrix switchers allow for any input to be sent to any or all outputs. They are ideal for routing HD broadcasting and other HD serial digital video sources such as digital cinema projection, biomedical imaging, satellite mapping and visualization, rental and staging environments, security surveillance, and other applications. Generally, they feature dual-redundant power supplies and are managed via front panel controls, RS232, RS422, and RS422 port for integration

Similarities & Beyond
The outlook of analog and HD-SDI matrix switchers is quite similar. Both transmit video signal via coax cable (Belden 1694A) and PTZ and audio signal via RS232, RS422, or RS485. However, with more powerful processor and operation system, the compatibility of HD-SDI matrix switchers is much broader than analog ones such as managing analog, HD-SDI, and 3G HD-SDI signals.

Easy Ride with IP
HD-SDI matrix switchers are generally equipped with Ethernet port(s) for network connection. Also, via digital video servers (DVS), SDI signals can be compressed into digital images, transmitting directly over an IP network. Over this distributed networks, centralized management can be achieved.

Stability and Redundancy
Evolving beyond analog matrix switches, HD-SDI matrix switchers are more or less different in terms of control, alarm notification, signal compatibility, OSD menu, and more. Thus, stability, reliability, and redundancy become even more important. For instance, modular design allows ease of servicing and expanding. Changeable card mode let power supplies, controller card, blowers, and some matrix cards be installed in redundant configurations. In case of redundancy, most HD-SDI matrix switches are configured with dual power supply based on demand. If the power source is not stable, the redundant power supply can be connected to different power source or self-built UPS.

Terminal T4 – Madrid-Barajas Airport
AENA (Aeropuertos Espanoles y Navegacion Aerea - Spanish Airports and Airspace).

Madrid-Barajas Airport is Spain's largest airport; it is also the busiest, with more than 50 million passengers a year passing through its gates on their way to both domestic and international destinations. Moreover, Madrid-Barajas is the main gateway for flights between Europe and Latin America.

Situated in an excellent geographical location, its capacity has doubled since 2006. With the addition of the new Terminal T4, Madrid-Barajas Airport has secured its position as a leader in worldwide air traffic. Furthermore, thanks to the expansion of its airport, Madrid is becoming an increasingly important international hub for economics, finance and business, not to mention conventions and events.

Business Objective:
The CGA (Centro de Gestión Aeroportuario - Airport Coordination and Management Center), located in T4, is the coordination center for the entire airport; this is where surveillance and the CCTV system are managed, among other things.

With regard to the video surveillance system in particular, AENA needed a flexible solution that was capable of integrating all the existing systems while offering sufficient capacity to manage the huge increase in traffic anticipated in the new and existing terminals.

This project therefore represented an enormous challenge considering the huge surface area, the number of buildings to monitor and the amount of programmed equipment involved.

Bosch's system was the perfect solution for the airport, thanks to the large capacity of the 8 Allegiant Matrix Switcher, providing distributed architecture and ease of integration, combined with the high quality offered by both the fixed (approximately 500 Dinion) and PTZ (approximately 500 AutoDome) cameras.

The global management system consists of various matrix switchers, each with a capacity of over 4000 inputs and 500 outputs, more than 3000 cameras distributed across all four terminals and, at peak times, more than 10,000 accesses an hour. Integrating all of these elements was not a simple job, but the high quality and reliability of Bosch Security Systems products made it significantly easier.

Thanks to the Bosch system installed at the site, more than 80 operators now have direct access to all images of the airport. They receive information from different door accesses and manage the graphic environment. They have immediate, efficient and reliable access to the tools needed to control and manage airport security, making their jobs a lot easier.

If the system ever needs expanding Bosch equipment is designed in such a way that new technology can be fully integrated with any existing components meaning that new solutions can be put in place quickly without affecting either passengers or the operator.

Saudi Arabian supermarket chain minimizes shrinkage with surveillance and PA systems

Editor / Provider: Bosch Security Systems | Updated: 11/6/2012 | Article type: Security 50

Over the past 40 years, Carrefour group has continued to grow so that it becomes one of the global distribution groups. As the second-largest and Europe's largest retailer, the group operates four main grocery store formats which are hypermarkets, supermarkets, hard discount and convenience stores. Carrefour group currently has over 15,000 stores, either company-operated or franchised. With a presence in 30 countries, over 54 percent of the group turnover derives from outside France. The group expects strong potential for further international growth in the future, particularly in such large national markets as China, Brazil, Indonesia, Poland and Turkey.
Carrefour hypermarkets are very large retail areas receiving thousands of visitors per day. Each store also has up to hundred employees. To maintain optimum security and safety for people as well as products Carrefour management has to overcome many operational challenges. The CCTV system considered as an antitheft system in the past is nowadays offering much more thanks to advanced features: monitoring of products and assets, assistance in managing manpower and operations as well as supporting safety equipment whenever incidents have happened.
Rajab and Silsilah (RS), a partner of Bosch Security Systems, ensured all its hypermarkets safety by deploying more than 10 CCTV and public address (PA) in existing facilities.
The products in this project include Dinion 455 and high speed dome cameras that allow 360 degrees surveillance (AutoDome). The control rooms are equipped with high quality reliable digital recorders along with matrix switcher. Thus, the used control equipment allows a comprehensive viewing of live and recorded images in the easiest way which makes the operators' tasks more efficient.
Praesideo, the digital public address and voice evacuation system in the market, allows to meet all the requirements for paging, sales promotions, call for prayers and for emergency evacuation.
Moreover, the system's optical network offers total freedom in its design of the system. It is even IEC60849 certified so that all emergency evacuation standards are met.
The solution Bosch provided for all the Saudi Arabian Carrefour markets has substantially supported their operations by increasing security and safety in the premises. Hence, employees can put the focus on their business again.

Infinova Surveillance Cameras Transport through Chinese Expressways

Infinova Surveillance Cameras Transport through Chinese Expressways

Editor / Provider: Infinova | Updated: 6/9/2011 | Article type: Infrastructure

Infinova announced that 2,870 Infinova cameras are covering 516 miles of expressways throughout the northern province of Shanxi in China.  Expressways include Shangman, Xihan, Baoniu, Weipu, Shangjie, Baomao, Tongxi and Zhong’nan Mountain Tunnel. Besides Infinova cameras, the implementations also include Infinova matrix switchers, DVRs, fiber optic transceivers and modems, housings, Ethernet modems and other Infinova equipment.

"These complex installations show how obtaining equipment, from the cameras with several types of transmission technologies, to the DVRs, from the same vendor can make implementing such systems easier," said Mark Wilson, Marketing VP, Infinova. "For instance, the Shangman Expressway is integrated with 136 sets of Infinova WDR, dome and PTZ cameras as well as matrix switchers. The Xihan Expressway features the same cameras plus 260 pairs of fiber optic modems."

The WDR cameras are featured throughout the expressways. For example, the Zhong’nan Mountain Tunnel, at 11-mile the longest tunnel in China, uses 305 WDR to view through the low-light and illumination within the tunnel.  WDR cameras offer superiority over CCD cameras, providing a higher signal to noise ratio, improved color rendering and better image quality, yielding excellent video for the various expressway surveillance sites, all of which require detailed images under difficult lighting conditions.

Surveillance systems used on the expressways differ from traditional surveillance systems. The highway systems have decentralized edge sites, distributed along the expressways, all of which need to stand up to weather extremes, temperature fluctuations and the other rigors of an outdoor environment. Due to the long distances, transmission quality is a challenge and fiber is the best choice for the intelligent transport systems. To assure reliability, both node fiber optic modems and video encoders/decoders are deployed.

The use of a node fiber optic modem reduces the engineering costs of an expressway surveillance system. Also called a bus digital fiber optic modem or link type digital fiber optic modem, the video transmission system is networked through one or two fibers. Deploying a standard time division multiplex and an add/drop multiplex approach, the node fiber optic modems save fiber resources and extend transmission distances.

Infinova Surveillance System Displays at Shanghai WorldExpo Culture Center

Infinova Surveillance System Displays at Shanghai WorldExpo Culture Center

Editor / Provider: Infinova | Updated: 4/1/2011 | Article type: Government & Public Services

The Shanghai WorldExpo Culture Center, shaped like a flying saucer (the “spaceship”) and one of Shanghai's new iconic buildings, is using Infinova cameras, modems and matrix switcher to provide security for the multiple six-story facilities that make up the complex, including an 18,000-seat theater.

“This is yet another Infinova installation at a prominent public facility,” said Mark Wilson, Marketing VP, Infinova. “From the Asian Games in Guangzhou to the Ertan Dam, Infinova is helping protect people and property.”

At the WorldExpo Culture Center, Infinova cameras are installed at entrances and exits, garages, fire control passages, stairways, control rooms, elevators, elevator halls and other important areas. Infinova fixed color cameras and minidome cameras are installed at indoor passages and halls. Areas with lighting fluctuations, such as the entrance and exit are installed with Infinova WDR day/night cameras. Infinova speed dome cameras are also installed at other important areas. All cameras are configured with auto iris lenses. WDR cameras also are used where needed. Video signals are managed at the control center, providing forensic image information for evidence recording and transmission. The system will automatically and dynamically adjust camera angles and select the most effective view and display.

Since the WorldExpo Culture Center site is expansive, distances between some cameras to the control center is far longer than standard coaxial cable can effectively handle. For transmission beyond 500 meters, Infinova fiber optic modems are deployed with signals from the cameras being transmitted to the control room via fiber.

The control center features an Infinova large-scale matrix switcher which supports up to 4,096 by 512 channels. WorldExpo Culture Center security personnel can predefine tours, time events and set alarm displays. Guards can view all parts of the center from the control room and respond quickly in case of an event.

With so many cameras deployed, it is impossible to display real-time video images for all cameras simultaneously in the control center. Instead, when an alarm occurs, an alarm handling routine is triggered and the matrix switcher calls the live video from the camera that triggered the incident and displays this on the monitor. Using this solution the video surveillance system can manage alarms from multiple inputs including the burglar alarm, access control and parking lot management systems.

Infinova Video System Protects Romanian Oil Refineries

Infinova Video System Protects Romanian Oil Refineries

Editor / Provider: Infinova | Updated: 2/14/2011 | Article type: Government & Public Services

Infinova announced that Rompetrol Rafinare SA, Romania's second largest oil company, is using an Infinova fiber optics video system to watch over its multiple facilities inside the 480 hectares (1,186 acres) Rompetrol Rafinare Refinery (formerly called the Petromidia Refinery) in Navodari. Using Infinova outdoor cameras, placed throughout the facility, many with an IP66 rating to protect against the maritime environment, refinery and oil terminal security operations staff can view what is going on within the refinery at all times plus refer to a record of any incidences using Infinova DVRs.

The system also features an Infinova V2010 video matrix switcher system which lets ten refinery security operations personnel view ten monitors while operating ten keyboards simultaneously. The system is used by Rompetrol Rafinare SA operators but administered by the integrator, Global Security System SA (Bucharest).

“We refine more than 14,000 tons of crude oil per day so it is very important that we can monitor activities throughout our refinery. However, it is quite difficult to provide high performance video in such a large area, especially one with all the electrical interference found in a refinery,” explained Laurentiu Sofron, Rompetrol Rafinare SA Project Manager. “Not only could Infinova supply us with the whole range of video products, from cameras to DVRs, they also could provide the fiber optics equipment. We felt that having all products in our system under one brand name would be a tremendous advantage for us.”

“With fiber optics, the refinery has no problems with electro-magnetic interference (EMI), radio frequency interference (RFI), cross-talk or ground loops,” said Liviu Vladulescu, Technical Director for Global Security System SA. “Rompetrol Rafinare SA does not need to worry about short circuits, sparks or fire hazards with fiber. In addition, the large signal carrying capacity of optical fibers makes it possible to provide not only many more signals, but also more sophisticated signals than could ever be handled by a comparable amount of copper wire.”

Vladulesco also noted that, in working with Infinova on other large projects, he knew that the Infinova technical support had the expertise his organization would need with local presale and post-sale engineering support.

Sofron said, “We have many other projects planned, including putting in video systems at our retail outlets. We will be using an Infinova solution there as well.”

Guangzhou Expressway Deploys Transmission System

Guangzhou Expressway Deploys Transmission System

Editor / Provider: SUBMITTED BY INFINOVA | Updated: 10/15/2010 | Article type: Infrastructure

Infinova provided a comprehensive digital video surveillance solution for fast, reliable, convenient and affordable surveillance for Guangzhou’s sprawling West 2nd Ring Expressway system.

The Guangzhou West 2nd Ring Expressway, also known as the Xiaotang to Maoshan section of Guangzhou City Circular Highway, connects six expressways of approximately 42 kilometers. The highway surveillance system includes decentralized edge sites distributed along the expressways. Due to the long distances, transmission quality has been a challenge for this intelligent highway system.

Traditionally, point-to-point (PtP) digital fiber-optic modems have been used in such systems, but create problems despite competitive pricing. Also, as a PtP setup requires fiber to run from each edge site to the monitoring site, the amount of fiber needed for a highway surveillance system can be high. This increases the overall investment and the cost of installation.

For the expressways, a comprehensive digital video surveillance solution was needed, which integrates real-time video transmission, online storage, archive search and playback, and multiple levels of remote control. This ensures the system’s improved security responses, faster handling of emergencies, timely and reliable video information for traffic management, and allows supervisors to call up and collect evidence.

Two types of transmission modes were used to assure reliability within the surveillance system — a fiber-optic modem integrating with a traditional video matrix-switching system. One link can achieve real-time transmission of up to 10 channels of video with eight channels of bidirectional audio and data (or 16 channels bidirectional data), and two channels of reverse data and one channel of Ethernet.

Since the surveillance system must transmit many types of signals — video, audio and alarm — the most logical choice was to create a centralized transmission distribution mode. Video signals collected at each toll gate and from cameras along traffic lanes were sent to the closest communica- SUBMITTED BY INFINOVA tions station to be compressed and encoded by video encoders working with the on-site digital video storage server. Ultimately, the data is transmitted to the monitoring and management center via the fiber ring network. The resilient packet ring channel is dynamically distributed to fully leverage the fiber wiring, which guarantees real-time surveillance of emergencies and faster response to incidents, including counterterrorist activities.

The network video surveillance system software can assign priority for different management stations, such as the overall control center, expressway monitoring center and area subcenter. Authorization levels allow the center to remotely call up, control and store video from the edge sites. In addition, distributed management allows every toll station to call up videos from monitoring sites by using its individually managed matrix switcher. Video can be retrieved and transmitted manually, by schedule or events, and can be viewed live on Internet Explorer.

The use of a node fiber-optic modem greatly reduced the engineering costs of the surveillance system. Deploying a standard time division multiplex and an add/drop multiplex approach, the node fiber-optic modems save the expressways fiber resources.

The industrial-grade OSE real-time main operating system assigns a unique internal 31-level priority of the network video encoder/decoder for multilevel priority management. Since it does not rely on server authorization control, the system is more stable.

The solution provides self and online checks for the encoder/decoder, DVR and their communication lines for troubleshooting purposes. With its rack encoder/ decoder, the system saves installation space at the local sites and the control center while ensuring easy maintenance for future system expansions.

Infinova Network Video Locks Down Chilean Jail

Infinova Network Video Locks Down Chilean Jail

Editor / Provider: Infinova | Updated: 5/13/2010 | Article type: Government & Public Services

Infinova announced 10 facilities in the Chilean private jail system are using Infinova fiber optic video multiplexers with dual data and audio transmission and reception capabilities along with Infinova analog matrix switchers with IP output for video transmission. The Chilean Ministry of Justice and Corrections has outsourced low and medium security correction facilities, including construction and management, to a private management company. The private jails are located throughout the country.

"Fiber optic transmission was chosen for this implementation because fiber preserves the quality of video signals, provides a high level of security, transmits at higher bandwidths and lower losses, and operates at distances five times greater than coaxial cable," said Mark Wilson, Infinova VP, Marketing. "Importantly, Infinova fiber optic products integrate with Southern Microwave's perimeter control systems, which the private jail uses to transmit audio and video images."

With the Infinova fiber optic video multiplexers with dual data and audio transmission and reception capabilities, the private jail system can transmit digitally encoded video channels with audio and data over one optical fiber.  Their data format supports factory default setting RS-232, DIP selectable RS-422, RS-485, Manchester or biphase. The analog matrix switcher with IP output lets them turn the analog signals from their cameras into digital signals for transmission over the Southwest Microwave equipment. For the private jail system, this is important because both the jail warden and the administrator can view what is going on using the matrix switcher via Internet connection.
