- Level: Intermediate
- Presenter: Eli the Computer Guy
- Date Created: March 2, 2012
- Length of Class: 50 Minutes
Purpose of Class
- This class teaches students about how IP Surveillance Cameras work and considerations for installing and maintaining them.
- Introduction (00:00)
- Overview (01:49)
- Networking Issues (12:39)
- Virtual PTZ (26:37)
- Demonstration (31:17)
- Final Thoughts (41:19)
- 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
- 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.
