FTP (File Transfer Protocol):
protocols, used to exchange files between computers/devices on networks. Network cameras
with embedded operating systems use FTP to send camera images to an authorized user's
computer or web site.
UPnP (Universal Plug & Play):
automatic peer-to-peer detection of devices on the network. Allows the discovery of UPnP-
enabled devices in a network environment.
RTSP (Real Time Streaming protocol):
streaming of audio and video. Mostly used for remote viewing of live or stored security
camera video over the Internet. RTSP can be considered as a "remote control" for controlling
the media stream delivered by a media server. RTSP servers typically use RTP as the
protocol for the actual transport of audio/video data.
CMOS Sensor (Complimentary metal-oxide semiconductor):
image sensor available in many IP network cameras with less circuitry hence consumes less
power, produces higher frame rate & is less costly as compared to CCD sensors.
Pan/Tilt:
IP cameras with panning capabilities can move back and forth horizontally in
order to monitor wider areas. In many cases a camera's panning functionality can be
controlled remotely from network PC using video management software. Tilt refers to an IP
camera's ability to be directed up and down in a vertical plane. The camera lens can be aimed
at a specific part of a scene, and in many cases the tilt can be controlled remotely.
Frame Rate:
The frame rate is used to describe the frequency at which a video stream is
updated is measured in frames per second (fps). If you want more accurate video then the
frame rate should be kept high. Lower the frame rate, lesser the image details.
Gain Control:
When camera produces a quality picture, it needs a sufficient amount of
light to produce a minimum stable picture, in case the light condition reduces to a certain
level, there is insufficient light to the camera to create a quality video picture. AGC
(Automatic gain control) increases the amount of amplification in these conditions to bring
the video signal up to the minimum required level. Besides increasing picture signal, AGC
also helps to reduce noise and picture attenuation.
