IP Surveillance Cameras

description
Info Level: Intermediate Presenter: Eli the Computer Guy Date Created: March 2, 2012 Length of Class: 50 Minutes Tracks Digital Surveillance Prerequisites Digital Surveillance Cameras Introduction to Digital Surveillance Systems Purpose of Class This class teaches students about how IP Surveillance Cameras work and considerations for installing and maintaining them. Chapters Introduction (00:00) Overview (01:49) Networking Issues (12:39) Virtual PTZ (26:37) Demonstration (31:17) Final Thoughts (41:19) Class Notes Overview IP Cameras are full fledged computers IP Cameras send the video over TCP/IP and can use Standard Ethernet networking equipment. They can store video either with: on board memory, send to an FTP Server, be controlled by an NVR (Network Video Recorder) Resolution is measured in standard pixels Features may require that you pay additional money to unlock capabilities Networking A single 5 MegaPixel Camera can use up 30Mbps of Bandwidth. Multiple Mega Pixel cameras can bog down a LAN. "Pushing Intelligence to the Edge" means that decisions about when to record video and other features are made by the camera itself and not a central NVR. Parallel Networks are used to give surveillance equipment their own dedicated Ethernet Network so that it does not interfere with Computer and VoIP communications. Power Over Ethernet allows you to power your IP Cameras through the network cable. Virtual PTZ Virtual PTZ allows you to zoom in on a specific area of a video while the camera is still recording the entire scene. Much better then standard PTZ. (A Single 20 Mega Pixel Camera could watch a very large parking lot.) Final Thoughts... IP Cameras are only expensive when viewed per item. When you look at the total cost for a project they can end up being much cheaper. 1 $2000 camera can do the job of 4 $500 cameras... Not all cameras are compatible with all NVR's. Make sure you budget not just for the cameras, but also for the licenses. The ability to record on an IQinvision camera is an extra $70 PER camera. Resources IQinvision Geovision IP Cameras
