Channel-Zero encoding, in video surveillance or NVR systems, is an option to configure the video recorder to stream a video feed composed of multiple camera views (channels) in one split-picture view. This allows the recording system to send one frame to a remote system, rather than numerous frames of the individual channels; thereby reducing ...
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 group. [ 168 ]
These cameras do not require a video capture card because they work using a digital signal which can be saved directly to a computer. The signal is compressed 5:1, but DVD quality can be achieved with more compression (MPEG-2 is standard for DVD-video, and has a higher compression ratio than 5:1, with a slightly lower video quality than 5:1 at best, and is adjustable for the amount of space to ...
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.

IP cameras with intelligent video surveillance technology can be used to detect flame and smoke in 15–20 seconds or even less because of the built-in DSP chip. The chip processes algorithms that analyzes the videos captured for flame and smoke characteristics such as color chrominance, flickering ratio, shape, pattern and moving direction.
