Video System - Wired or Wireless
With all the advent of cell phones and other “cordless” devices now prevalent in our world, “wireless,” in the Video Security world, is really a misnomer.
Why?
What is “marketed” as “wireless” is really not wireless. Actually, on either end of devices (transceivers on the analog side and routers on the IP side) there are wires.
Yes, it is possible to transmit video images through the airwaves “wirelessly” but given there must be wires (and therefore power), on both the sending and the receiving ends, it is not always as simple (or as economically feasible) as the concept may sound.
People usually look to a wireless solution in Video Security applications is usually for one of two reasons:
1. They want to view the subject from an angle where there is
no convenient way to wire the camera, or,
2. There is a significant distance between where a camera (or a
group of cameras) is (are) located and where the video
information is being recorded – this is true for analog as well
as digital (or IP) cameras.
CONCLUSION
Suffice to say, with respect to video security, a wired solution is always better (provides clearer imagery, is less problematic over time and is 99% of the time, less costly than a wireless solution.
For those who like more detailed (or perhaps more technical explanations) we provide the following references...
