Wireless CCTV has become very commonplace as a means to video record locations such as banks, warehouses, convenience stores, etc. as a means of security or loss prevention. Here are some key points regarding some of the more common systems.
Wireless CCTV systems utilize wireless transmitters from the camera to the receiver to avoid having to run wires. The ability to transmit video signals without wires can be very convenient for many locations which have limited access or ability to run wires.
Typical applications can include manufacturing operations or areas with limited accessibility. The wireless transmitters normally operate on a 2.4 gHz signal.
One of the disadvantages of wireless CCTV is limited bandwidth available on a wireless connection. Since a video signal can contain a great deal of data, it is necessary to compress the signal and/or transmit at lower resolution.
For many application, a lower resolution or compressed signal is fine. However, particularly for applications involving facial recognition or the need to examine finer details, a wired connection from the camera to the receiver is advisable. Be sure to determine what your requirements are first so you can avoid trouble down the road.
A simple wireless CCTV system consists of a camera and a remote receiver. It is also possible to expand the system by adding some type of recorder like a VCR or DVR. At the receiver end there is a lot of flexibility.
Costs can vary widely but you can expect to pay well under $200 for a two camera system and simple receiver. This type of receiver is also normally expandable to four or more cameras. Options such as various types of controllers or smaller cameras will add to the cost but overall this is a pretty cost effective application.
Depending upon the type of receiver chosen, several cameras can be utilized and controlled. Some cameras have the ability to pan so they can cover a wider area. In this case it is necessary to have a receiver with controller capabilities.
For these kinds of application, it is advisable to consult with dealers who specialize in this type of work. They can assist you with equipment selection and installation support. Pricing is very competitive as much of the equipment is produced in the Far East. A strong dealer will also be able to provide you with excellent product service and support which is certainly important to keep your network operating reliably.
So for the right applications, a wireless CCTV installation is definitely the way to go and will provide you with very satisfactory results.
