Can I use wireless transmission from security cameras to computer instead of cables?
A qualified yes. Basically it depends on the range, frequency and type of the transmitter/receiver units, the conditions under which they are to be used and the number of units you want to use. Most transmitter/receivers today are 2.4GHz units. This high frequency has the advantage of longer range per power unit but only in clear line of sight. 2.4GHz signals do not travel through objects (walls, trees etc.) very well. Low power, low range 2.4 GHz transmitters are cheap but usually produce very poor image quality. Until recently, higher power units were very expensive (approaching $1,000 per pair). Today there are some higher output 2.4GHz and 1.2GHztransmitter/receiver units available (see our CCTV accessories page) at more reasonable prices. Our units have four selectable operating frequency channels so up to four pairs of transmitter/receivers can be used in one system. For longer transmission distances, though, even with long range high power units, it is important to have as clear
