They could be used for security purposes to deter criminals monitor workers and activities of equipment. Not all video surveillance system are the same and it is therefore important to take note of their features. The IP video surveillance system is much more flexible and future proof for customers and installers as compared to the traditional analogue system. Being an open system they do not use proprietary equipment and the system can be monitored from wherever internet access is available. Here are 10 facts to take note of when considering a IP Video Surveillance System: 1. IP Camera The Camera is the eye of the surveillance system and therefore is one of the most important components of the system. Image quality is the most important feature of the camera. This is especially so in security surveillance and monitoring applications where properties and lives could be at stake. A good image quality allows good details to be shown even when zoomed in. IP Cameras such as the GRID’s 720ºhi-resolution 12MP camera has a full undistorted 720° field of vision and with no blind spots. Because of its wide field of coverage one 720º camera is able to do the job of three bullet cameras. This means a great saving over using bullet cameras and less wiring of cameras needed. 2. Indoor or Outdoor system

Power over Ethernet PoE Switch The PoE switch has two functions it sends data to from the camera and provides power to it. By powering the IP cameras directly it eliminates the need of installing a power outlet for each camera as in the traditional system. 4. Network Video Recorder NVR The NVR which is the equivalent of a digital video recorder DVR of the tradition surveillance system records the images capture by the IP cameras at a higher resolution 1028p 1920 x 1080as compared to the DVR 720 x 480. The NVR therefore offers clearer image of the two. 5. Connections As IP Cameras and NVRs are network based they need not be connected directly to each other. IP Cameras are connected to the network via the PoE and the NVR is connected directly to the network. Video images captured by the IP camera are transmitted to the NVR via the network. This is a much similar set up as compared to the traditional surveillance system. 6. Video Analytics Advance IP cameras also come with additional features such as motion detection capability. When movements are detected alerts can be sent via the internet to a smartphone or to the security firm. A video clip of the incidents can also be sent along with the alert. 7. Video Compression Especially for a setup with many IP cameras and for the potential of adding on more cameras in future choosing the right video compression technology e.g. Avi mpeg2 or mpeg 4 is important to prevent network congestion. 8. Storage Capacity When choosing video recorders an important question to ask is how much storage would be needed. This would depend upon resolution of the cameras the amount of archived footage to store and the duration to keep recorded footage. As an example to determining storage space needed of a four-camera system each with 3-megapixel resolution and a frame rate of 5 fps using mpeg-2 compression on a NVR running 24 hours a day and storing for 7 days per camera would require 2.29 terabytes of storage space for footage according to the Super circuits calculator.

Cable Selection The most commonly used cables for the infrastructure of video surveillance system are the cat 5/6 coaxial cable and untwisted pair copper wire. These cables have a distance limitation of up to 100 meters. For a small area of coverage these cables are adequate. For large area of coverage exceeding 100 meters the other option to consider would be fibre optic cable such as the GRID’s GPON fibre optic cable which has a distance of up to 20KM. Fibre optic cables are also not prone to electromagnetic interference takes up less space lighter and easier to be laid as compared to copper wires. 10. Audio Integration Video management system can also integrate audio into its surveillance system. Audio is useful for systems that require hearing and speaking with possible perpetrators For more information on GRID’s Video Surveillance System and other telecommunication needs please contact 6486 8777.
