Analog wireless is found in three frequencies: 900 MHz, 2.4 GHz, and 5.8 GHz. Currently, the majority of wireless security cameras operate on the 2.4 GHz frequency. Most household routers, cordless phones, video game controllers, and microwaves operate on the 2.4 GHz frequency and may cause interference with a wireless security camera.
Zigbee is an IEEE 802.15.4-based specification for a suite of high-level communication protocols used to create personal area networks with small, low-power digital radios, such as for home automation, medical device data collection, and other low-power low-bandwidth needs, designed for small scale projects which need wireless connection.
Wireless cameras are also easy and inexpensive to install. [166] Previous generations of wireless security cameras relied on analogue technology; modern wireless cameras use digital technology with usually more secure and interference-free signals. [167] Wireless mesh networks have been used for connection with the other radios in the same ...
