The truth is, wireless cameras may be installed or mounted in locations not available before to standard wired cameras. And apart from the ease of use and convenience of access, wireless security cameras also allow users to leverage broadband wireless internet in proving seamless video streaming online. Analog wireless is more on transmitting video and audio signals by making use of radio frequencies. Most of the time, the analog wireless has a 300 feet or 91 meters transmission range in an open space however, doors, furniture and walls may reduce this range.
Where To Start with Security and More
Analog wireless comes in 3 different frequencies while the lowest is the 900 MHz, 2.4 GHz and 5.8 GHz. Most of the wireless security cameras operate on 2.4 GHz frequency as of now. Majority of the household routers, video game controllers, cordless phones and even microwaves are also operating on 2.4 GHz frequency and thus, might potentially cause interference with the wireless security camera.

Having a wide transmission range, high quality audio and video, a two way communication between the receiver and camera are just some of the benefits that come with this system. And because of the fact that it’s digital, you are actually capable of transmitting functions and commands similar to turning the lights off, connect several receivers to one recording device like the DVR and many more.
