- CCTV Camera & IP Camera Security System
CCTV Camera Pros offers a complete line of quality CCTV cameras and security cameras for surveillance systems. An Internet protocol camera, or IP camera, is a type of digital video camera commonly employed for surveillance, and which, unlike analog closed circuit television (CCTV) cameras, can send and receive data via a computer network and the Internet. Although most cameras that do this are webcams, the term "IP camera" or "netcam" is usually applied only to those used for surveillance. An IP camera is typically either centralized (requiring a central network video recorder (NVR) to handle the recording, video and alarm management) or decentralized (no NVR needed, as camera can record to any local or remote storage media). The first centralized IP camera was Axis Neteye 200, released in 1996 by Axis Communications. IP cameras are available at resolutions from 0.3 (VGA resolution) to 29 megapixels. As in the consumer TV business, in the early 21st century, there has been a shift towards high-definition video resolutions, e.g. 720p or 1080i and 16:9 widescreen format.IP cameras differ from previous generation analog cameras which transmitted video signals as a voltage, whereas IP camera images are sent using the transmission and security features of the TCP/IP protocol. Some advantages to this approach include: Two-way audio via a single network cable allows users to listen to and speak to the subject of the video (e.g. gas station clerk assisting a customer on how to use the pay pumps) The use of a Wi-Fi or wireless network. Distributed intelligence such as video analytics can be placed in the camera itself allowing the camera to analyze images. Secure data transmission through encryption and authentication methods such as WPA, WPA2, TKIP, AES. Remote accessibility allowing live video to be viewed from any device with sufficient access privileges. PoE Power over Ethernet to supply power through the ethernet cable and operate without a dedicated power supp.
