compressed video streams. Network
Cameras are the fastest growing trend in the

Network cameras have built‐in motion detectors and
compression engines,
which enable the DVR Server to use a minimum of its computer resources;
therefore,thesamecomputercanalsobeusedforothertasks.

PTZCameras
WhatarePTZCameras?
PTZ camera is the camera with the mechanical assembly for Panning, Tilting and
Zooming the camera. There are many types of PTZ cameras available and their cost
variesbased on Speed, Zoomcapacity,Manufacturer,etc.Network PTZ camerasdoes
not require any addition wiring or devices,
since PTZ commands are being send over
TCP/IPnetwork; therefore,making installationprocess muchsimpler andeliminatinga
