analog wireless cameras transmit their signal in the low frequency of 900 MHz, 2.4 GHz and 5.8 GHz Note that most of them reached the 2.4 GHz, the same group that many families of wireless devices such as cordless phones, and operate a video game controller. Violation may result, if you are at home.
The advantages of analog wireless security systems are less expensive than their digital brethren, and you can have multiple recipients.
The disadvantages, which can cause interference with other devices in the home. The transfer is not secure. video is of poor quality that digital technology, and every speech is getting worse.
Power Transmission
Reduce system cost of 5.8 GHz is likely, a transmitter of 10 MW, which can, ideally, are transmitted to 300 meters line of sight between the transmitting antenna and receiving antenna. This happens very rarely. This is a generalization and conditions, such as the distance, weather conditions and visibility is seriously affected.
When choosing security wireless analog cameras, you must ask you to determine the strength and sufficiency of it to overcome obstacles in your system.
