Guide to IP Cameras

Internet protocol (IP) Cameras are quickly growing as the dominant technology in surveillance and security video monitoring devices. Unlike CCTV cameras, which generally broadcast an analog signal, IP cameras are able to send a digital signal through a computer network as well as store digital data directly on the device itself on solid-state memory. Many IP cameras also allow for two-way communication, so that the device itself can be used to communicate with users on the camera-end.

Advantages over Closed Circuit TV

IP Cameras have higher image resolution than analog counterparts, and are also easier and cheaper to install. Whether the user chooses to use the wireless features offered on many cameras, or use an Ethernet cable, the installation is still easier and cheaper than installing a CCTV camera system. Also, IP cameras can be linked to remote devices such as the iPhone and other smart phones for security monitoring on the go.

Bandwidth

The formula commonly used to determine Bandwidth for IP Camera requirements is:

Bandwidth (Mbits) = FrameSize (Kb) * 1024 * 8 * FPS * Cameras / 1000000


Common Terms

Resolution – In pixels (like 640 x 480)

Compression – File Type: (like MPEG, etc)

FPS – Frames per second (Usually 5-15 FPS)

Storage – The amount of disk space required to store video, (in Gigabytes)


Other features to consider

If the IP Camera is going to be used for outdoor surveillance, make sure your camera has outdoor capabilities.  Also, some cameras have nighttime modes that use Infrared (IR) LED’s to help monitor during low-light settings.  Some applications also require that the camera have pan and tilt functions, while many times a fixed position is preferred. In this case, the viewing angle is important, so make sure the viewing angle is large enough for your area.
