IP Cameras And Their Advantage As A Surveillance Camera

Posted by ProVisual on 8/22/2014 to News

An IP camera, otherwise known as 'Internet protocol camera' is a digital video camera commonly used for surveillance. IP cameras 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 an IP camera for security purpose. The function of these cameras is to identify a person or event, therefore image quality is very important. When the video (recorded by an IP camera) is compressed, the images quality suffers and consequently the storage efficiency rises. Hence correct image quality should be configured within the IP camera according to the requirements of the work area where IP camera is employed. IP cameras give high image resolution; they have a minimum resolution of 640x480. Some IP cameras provide HDTV image quality at 30 frames per second and multi-megapixel resolution.

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

In IP cameras, there is a two-way audio via a single network cable --those who are watching the video can communicate with people in the video. For example, gas station employees can talk to their customers via an IP camera. IP cameras are very flexible as they can be moved around. In IP cameras, data can be securely transmitted using encryption and authentication methods like AES, TKIP, WEP, WPA, and WPA2. There is often a misconception that if the internet goes down, IP cameras also go down. The truth is, in IP cameras the internet connection is not a necessity to record. IP camera datum are recorded to a local storage device and the internet is used for remote viewing the video stored onsite. Also in some IP cameras live video can be viewed from any computer, smartphones and other devices.

IP cameras can function on a wireless network. For Initial configuration a router has to be used and once the IP camera is installed, it can then be used on the wireless network. Such IP cameras are used in defense forces, especially for navigation purposes. Modern IP cameras can function without an additional power supply. This is possible using the PoE-protocol which gives power via the Ethernet-cable. Modern IP cameras come with advanced motion sensor controls and extreme low-light functionality. IP cameras are available in a wide variety of sizes. An IP camera is a powerful device which can transmit digital video signals directly via an Internet network and allows quick remote access, digital storage and more. With their numerous benefits over traditional cameras, IP cameras are the next generation of video surveillance.
