With an auto-iris lens, the iris is controlled automatically to regulate the amount of light entering the camera. This is ideal for camera installations in outdoor locations, high- contrast situations, and areas where lighting conditions fluctuate.

(Bayonet Nut Connector) Video connector, the most commonly used in CCTV.

A CCD image sensor is a light-sensitive image device available in many IP network cameras. The sensor transforms light into electronic signals. CCD sensors provide strong light sensitivity allowing for video surveillance in low-light conditions.

CCTV (or closed-circuit television) refers to the use of analog surveillance cameras to submit a video signal to a specific set of monitors. Since a CCTV system is closed, only a limited number of viewers can access the footage from a single location. With the arrival of IP-based surveillance, analog CCTV systems are now being superseded by improve [..]

The two industry standards for mounting a lens on a camera. The C-Mount lens has a 17.5mm flange back distance. The CS-Mount lens has a 12.5mm flange back distance.

A Digital Video Recorder is a generic term for a device that is similar to a VCR but records television data in digital on a hard drive as opposed to a VCR tape. A DVR looks like a VCR and has all of the same functionality of VCR (recording, playback, fast forwarding, rewinding, and pausing) plus the ability to skip to any part of the program witho [..]

Ethernet is a standard technology for network communications in LANs (Local Area Networks). Ethernet LANs use twisted pair cabling, with network devices connecting to a central cable or hub. The most common Ethernet systems are 10BASE-T and 100BASE-T10, which transmit data at speeds of 10 Mbps and 100 Mbps.

The field of view represents the complete area of coverage provided by a network camera when viewed at full frame. Field of view can be determined by camera type, lens, and image resolution.

FTP (File Transfer Protocol) is a network protocol used to transfer files from one computer to another, or between devices on the network. An FTP client can connect to an FTP server to access and manipulate the files stored on that server.

Image compression reduces the file size of video images to optimize bandwidth while streaming surveillance footage. The most common compression technologies for IP network cameras are Motion JPEG and MPEG-4. H.264 is the latest compression technology that significantly reduces the file size of high-quality video images.
