2.4 GHz: 4 Channel video transmitter. Approximately 2″ x 2″ x 1/2″. No tuning required. We generally recommend 2.4 GHz over 434 MHz or 900 MHz, as the overall video quality is better. Range varies from 200′ to 700′ depending on environmental conditions. Operates on 12 Volts. These units are FCC approved. All 2.4 GHz wireless cameras come with a transmitter and a reciever. 434 MHz: Lower frequency amateur band. Operates on one channel which is picked up directly by a television. You do not need a receiver. With a TV: set to channel 59, cable mode but remove actual cable from the input, and use a UHF antenna (high gain increases the range) ears to receive the signal. With a hand held TV: can be received on UHF band just below channel 14. Range can vary from 300-400 up to 1,000 feet. THe range can vary depending on frequency interference and other environmental factors. Antenna is approximately 6 1/2 inches. Operates on 9 Volts. 900 MHz: Amateur band. 4 channels available in the 900 band.
