Types of Systems Analog DVR Systems — Use Siamese Cable to connect cameras. All cameras are directly connected to the system. PC Based Systems are simply PC’s with a DVR card installed. DVR Appliances are specially built computers that are cheaper then PC Based systems, but are generally impossible to repair. Video quality will never be better then DVD quality (Which is not actually very good) IP NVR Systems — Use Ethernet and TCP/IP to Transmit Video These systems support very high resolution cameras FPS — Frames Per Second — How smooth the video viewing is 30 FPS = Real Time, 15 FPS = Perceived Real Time, 7 FPS shows Jerky Video FPS can be measured: Real Time Viewing and Recorded Video, It can be per card/ system and/ or per Channel Resolution IP Cameras use standard resolution measurement for any digital camera …
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 …

Info Level: Beginner Presenter: Eli the Computer Guy Date Created: February 24, 2012 Length of Class: 70 Minutes Tracks Digital Surveillance Prerequisites Introduction to Digital Surveillance Systems Purpose of Class This class demonstrates the abilities of Digital Surveillance Cameras and explains the differences between types of cameras. Chapters Introduction (00:00) Analog vs. IP Cameras (03:24) Analog Cameras Configuration (08:31) Camera Form Factor (22:17) Camera Feature (35:14) Purchasing Cameras (49:04) Final Thoughts (57:49) Class Notes Analog vs. IP Cameras NVR — Network Video Recorders are used for IP Cameras, DVR – Digital Video Recorders are used for analog cameras. Resolution for Analog Cameras is TVL — Television Lines, for IP Cameras resolution is based on pixels. Analog Cameras Configuration Analog cameras use RG59 (Siamese) Cable for connecting to the DVR. Siamese cable is a coax cable and a 12 volt power cable contained within a single sheath. Analog cameras use BNC connectors (British Naval Connectors) You can use adapters for cameras to connect to RCA or standard coax cable connection on TV’s. Make sure to use the right power adapter for the camera. BalUns allow you to use Cat5 Cable for analog camera wiring. This is NOT an Ethernet, or a TCP/IP connection. It simply uses Cat5 cable to transmit an analog signal. Camera Form Factor Bullet Dome Box — Box cameras require you to buy the lens and mount additionally. Vandal Proof Dome PTZ — Pant/ Tilt …
