Wireless Video Systems

Consultation, Design, Installation, Maintenance & Service

Big ImageWireless video is used most often on special applications when it is either impossible or it is cost prohibitive to run cables between the camera and the monitoring station. Best results with wireless video systems are achieved when the following conditions are met:

1. There is a line of sight between the camera and the monitoring station.

2. The camera side video transmitter and the monitor side video receiver can be mounted high off the ground (i.e. at least 30 feet or more).

3. There are no sources of interference in the vicinity of the system, especially on the frequency that the system is operating on.

4. It is desirable to have 110V AC power available at the camera site.

Wireless video can be transmitted on several different channels and power levels. The choice is based on the distance between the camera and the monitor, licensing requirements or government applications.

There are license free channels on low power 2.4 GHZ and 5.8GHZ channels. The 2.4 GHZ system supports up to 4 cameras and the 5.8 GHZ system supports up to 10 channels. Each channel can handle video and audio.

Higher power transmission requires FCC licensing for private use. Government agencies can us a 1.8 GHZ band that is reserved only for Federal government agencies.

In general, wireless video is used as a last resort and is more costly than a wired system. However, when installed properly, it produces excellent picture quality as well as accurate pan, tilt and zoom control.
