More real-life cases needed for HD-SDI

Standardization is a deciding factor for a product to be widely adopted. Although it may be harsh to ask a new ecosystem to immediately produce universally usable standards, it is nonetheless a problem HD-SDI must resolve. It is not just a matter of standardizing cameras, said Zhou Sheng Qiang, GM of Video Surveillance at Keda Technology. "First on the list is cabling. Although HD-SDI can utilize

2012 — Year of HD-SDI?

Within two years, HD-SDI has established substantial awareness in the marketplace, as tangible products materialize from an earlier TV transmission concept. Market penetration, on the other hand, has been less than stellar, due to component/system pricing and deliverability issues. Is 2012 really the year of HD-SDI? HD video surveillance is an unstoppable, irreversible trend. Indeed, it is one of

New LED Illuminators Range From Videotec

In the night video surveillance, a perfect lighting is vitally important to get a clear vision and outstanding image quality.Videotec has created a new and complete range of LED illuminators for cctv night monitoring, using the best quality components and the latest technology. That's why the GEKO lights give full warranty of their optimal performance, high efficiency, maximum durability and cost-

What It Takes to Get Wireless Surveillance Right

In addition to having a solid technical background in IP, it is critical to know how radio frequencies (RF) propagate. “When cellular carriers deploy networks, they don't just throw up cellular base stations in random locations,” said Geoffrey Smith, VP of Business Development and Strategic Accounts, Proxim Wireless. “It's the same thing, for wireless, with base stations and subscriber radios. You

Sending Security Video Through Thin Air

The wireless technology market for security is growing at a double-digit rate, as systems become easier to user and more cost-effective. Beyond city surveillance, there are other surveillance applications where wireless networks show a lot of promise, including transportation/transit, utilities and remote industries.Wireless technology is becoming more capable of handling burdensome video data tha

Preparations for IP Video Storage

- Users can reserve channels in advance, so that no additional cost is required - Servers are better at handling larger expansions. - Proper planning by consultants or integrators is a key requirement for a cost-effective solution meeting the required security levels

Keeping IP Video Reliable and Resilient

- Window-based software is more prone to stability issues, hacker issues and requires firewalls. - Linux-based software is comparatively low-maintenance. - When PCs play a bigger role in the recording and movement of data, the processing power is of greater importance.

How to Achieve Video and Audio in Synchronization

Many network cameras offer audio support, be it built-in microphones and/or mic-in/line-in jacks. Audio signals are transmitted across the network the same way video data is. In digital systems, audio and video data is sent in separate packets. In order to achieve perfect synchronization, the audio and video packets must be time-stamped. Video/audio synchronization happens at the bit level. “We cl

What's Next in Video Recording and Storage?

Stand-alone NVRs will continue to thrive in low-cost environments, such as independent retail stores and SMBs, said Jeff Whitney, VP of Marketing at Intransa. “Their main benefits are cost, simple functionality and setup. Preconfigured systems, especially those that include cameras and cabling, will continue to take up much of this unsophisticated market segment.”

Selection Criteria for Panoramic Cameras

- An important step is to buy or borrow one and test it prior to large-scale deployment - Check to see how many video streams are coming out of the camera, as well as total bandwidth and storage requirements. - The biggest question concerns the true resolution and performance of lenses, since they impact not only panoramic and 360-degree cameras.
