It is widely known that choosing the right camera and back-end storage device are crucial in terms of video surveillance. As a matter of fact, transmission is the key factor that is easily overlooked in the entire monitoring systems.
If we're talking about surveillance in a flat or wherever wire cabling construction is convenient to install, stable transmission might not be a tough task to achieve. However, when it comes to video surveillance for traffic utilities, a wrong set of transmission system can make the project a nightmare if you do not fully understand what you are dealing with.
In the following paragraphs, asmag.com would like to show you some decisive aspects on the advantages of applying wireless transmission systems and reasons why you should especially consider to deploying in traffic sector.
Advantages of Going Wireless
1. Flexibility: No matter it is for 100 meters or 40km, wireless transmission can easily tailor to different circumstances. Meanwhile, since there is nothing holding devices back, you can move the entire system around just to fit in new decoration. Distance and cabling can hardly be any issue if wireless system is your call.
2. Easy to Install: All you have to do is providing certain data such as transmission distance and range of bandwidths; the systems will be all set when it is arrived at your doorstep, and it takes only few steps and steady hands to mount the devices at the places you want.
3. Cost-saving: Cabling can cost a huge amount of your fortune, not to mention all the follow-up maintenance. Meanwhile, don't forget that hiring professionals to install the surveillance systems and cables is definitely not going to save you any penny.
Wireless Transmission for Traffic Utilities
City Traffic and Highway
Let's start from the basic – city traffic and highway. First of all, in the middle of a metropolitan, it is extremely difficult to install cables or upgrade the cabling infrastructure from time to time. Since you cannot stop the city from being functioning and it is even harder to keep cables from being damaged while all kinds of vehicles running by all the time. It just costs too much to maintain cable transmission systems.
Secondly, distance has always been an issue! On the highway, it is not realistic to stick to wire transmission if we're talking about a matter of 30-kilometers. Furthermore, there is a great chance that the highway is running across areas under harsh environment condition such as extremely low and high temperatures, etc. It is vital that the devices can work under various conditions.
Some traffic construction projects might require surveillance systems for monitoring constructiion sites and then continuously deploy the same systems for traffic monitoring. Wireless transmission is definitely the solution made for this demand. Rather than worrying about cabling, you only need to reset the systems according to different environment.
Harbor
Coast and sea shore are one of the trickiest locations for setting up surveillance devices. Industrial enclosure is a must-have due to the erosive environment. Other than that, wireless system seems to be the most reasonable solution for harbor application, since it would be a tough task to tailor wire transmission to various demands.
When it comes to wireless transmission, a crucial prerequisite is the line-of-sight (LOS). The Wi-Fi connection fails when containers or ships blocking in between. Without auto-reboot and auto-reconnection functions, it would require technical support to reconnect and reset the systems every time disconnection occurs. Therefore, auto-reboot and auto-reconnection functions are absolutely necessary, enabling the wireless connection back to work in a just couple seconds from disconnection.
Airport
Any trespassing incidents in the airport surrounding area can lead to destructive consequences. Maintaining wire surveillance systems can be troublesome, as previously mentioned; wireless equipment seems to be a wiser solution that saves you some troubles and ensures airport 24/7 security and operation.
Dynamic Frequency Selection (DFC) is an important function that comes with the wireless system, in order to make sure that the surveillance frequency will not interfere the communication between control tower and airplanes. DFS allows wireless LANs to coexist with radar system, and automatically selects a clean channel and frequency.
