Article Written By: emilyrobinson01

Internet protocol camera is a digital video camera commonly used for surveillance. They are capable of sending and receiving data through a computer network and the Internet, whereas, the analog closed circuit television (CCTV) cannot be used to perform this function.

Resolution and image quality are key factors to be considered when selecting one for security purpose. The function is to identify a person or event, therefore image quality is very important. When the video is compressed, the images quality suffers and consequently the storage efficiency rises. Hence correct image quality should be configured according to the requirements of the work area where it is employed. They give high image resolution with a minimum of 640x480. Some types provide HDTV image quality at 30 frames per second and multi-megapixel resolution.

Irrelevant parts of the recorded video can be clipped out. This feature allows the storage consumption to decrease by approximately 70%.Modern IP cameras enables on board recording up to 32 GB. In case of network failure, it can continue recording until network reconnection occurs. Instant updates can be sent to computer or smartphone. The technology is making a fast progression in the surveillance market. Users can view recorded scenes in very high detail, using IP video technology.

IP cameras are very flexible as they can be moved around. Data can be securely transmitted using encryption and authentication methods like AES, TKIP, WEP, WPA,WPA2.

There is often a misconception that if the internet goes down, IP camera also goes down. The truth is, mostly IP cameras are recorded to a local storage device and the internet is used for remote viewing the video stored onsite. Also live video can be viewed from any computer, smartphones and other devices.

They can function on a wireless network. For initial configuration a router has to be used and once it is installed, it can then be used on the wireless network. Such IP cameras are used in defense forces, especially for navigation purposes. Modern types can function without an additional power supply. This is possible using the PoE-protocol which gives power via the Ethernet-cable.
