IP CCTV Surveillance Cameras
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" has become synonomous with those used for CCTV surveillance systems.
There are two distinct types of IP cameras:
Centralized IP cameras, which require a central network video recorder (NVR) to handle the recording, video and alarm management.
Decentralized IP cameras, which do not require a central NVR, as the cameras have recording function built-in and can thus record directly to any standard storage media, such as SD cards, NAS (network attached storage) or a PC/server.
The most significant advantage is the amount of data that makes up each individual frame (picture) of video. Traditional analog video contains just over 300,000 pixels. IP cameras easily deliver
2,000,000,000 pixels or more! That requires more; more storage, more bandwidth and more knowledge of how all of these parts work together to meet your expectations. That knowledge is what separates VIALARM from other security vendors.
