An analog surveillance camera begins with a CCD sensor and then digitizes the image for processing. But before it can transmit the video, it needs to convert it back to analog so it can be received by an analog device, such as a video monitor or recorder. Unlike IP cameras, analog have no built-in web servers or encoders and require no technical maintenance. These functions are implemented in the recording and/or control equipment. In simple words, analog cameras are connected via coaxial cable to the digital video recorder. It is widely used for surveillance in various enterprise organizations. We have various forms of CCTV such as Dome, Bullet, Miniature, HD, Varifocal, Day and Night (IR), PTZ etc...
IP Camera (Network Camera)
What is commonly known as an IP camera, is a camera that digitizes and processes analog images, encodes them internally, and then transmits the video information digitally over an Ethernet connection to a computer or similar device. An IP camera can have either a CMOS or a CCD sensor, and is available in the same styles as traditional surveillance cameras such as Pan/Tilt/Zoom, domes, bullets, box, infrared, covert, and wireless. We have various forms of IP CCTV such as Dome, Bullet, Miniature, HD, Varifocal, Day and Night (IR), PTZ etc...
Digital Video Recorder (DVR)
DVRs are an important part of any successful CCTV project. Video resolution is getting larger, recording speeds are getting faster, and video data compression is reducing the video data file size. TeraByte storage capacity is becoming common in many CCTV applications. Network or remote monitoring of CCTV video is standard in all professional DVRs on the market in 2007 and video distribution across LANs, WANs, and the Web have given the DVR a new market outside of video security known as Business Systems Monitoring that allows management to monitor specified key business areas 24 hours a day. No longer just a security video recorder, the DVR has become a business tool for management with remote monitoring applications.
Network Video Recorder (NVR)
Unlike its predecessor, the DVR, a NVR is not limited to be in the same area as your cameras cabling to one section. The unit can be placed virtually anywhere, it simply just needs to be on the same LAN network as the IP based cameras. In terms, a network video recorder is distinct from digital video recorders as their input is assigned on a network rather than a direct connection to a video capture card. Video on a DVR is encoded and processed at the DVR, while video on an NVR is encoded and processed at the camera, then streamed to the NVR for storage or remote viewing. An NVR is a software program that records video in a digital format to a disk drive, USB flash drive, SD memory card or other mass storage device. An NVR contains no dedicated video capture hardware. However, the software is typically run on a dedicated device, usually with an embedded operating system. NVR is used in IP video surveillance systems. Because of the nature of these units, a camera that is capable of capturing High Resolution (Mega Pixel cameras) will record and playback as that desired resolution unlike a DVR system. Hybrid DVR security systems exist which incorporate functions of both NVR and DVR.
