 A
DVR card is a digital video recording device specially designed
to enable a PC to accept audio-visual feeds from security cameras
through BNC connections. The DVR card graphic on the left is a 4-channel
card which when inserted into the expansion slot of a PC will recieve
video feeds from 4 non-IP surveillance cameras over coaxial cabling,
thus turning the PC into a video recorder. The PC may then be connected
to a LAN, WAN or Internet via RJ-45 and CAT5/6 cabling or wireless
means. Then you can have access to as well as view, search and control
live and stored video from all connected cameras from anywhere in
the world!. Motion detection, alarm management and configuration
for FTP, HTTP, PPPoE as well as hard disk recording are some of
the features. Usually a DVR driver software accompanies a DVR Card.
Because cameras are connected directly to the PC no bandwidth consumption
results until someone logs into view the cameras over the network.
This is one advantage over IP cameras which are bandwidth intensive.
Up to 32 cameras can be used with a PC DVR system. This is ideal
for most business office environments. |
Stand-Alone
DVR System (LAN/WAN/web optional) |
|  Stand-alone
DVRs are speciallised digital video recording equipment which accept
video feeds from surveillance cameras(usually non-IP) over BNC connections.
DVRs perform multiplexing functions such as hard disk recording,
search and play back, motion detection,alarm management, archiving
and pan-tilt-control of cameras simultaneously.
With LAN/WAN options, a DVR combines the simplicity of VCR functionality
with the sophistication of TCP/IP networking, thus converting your
system into one which could be accessed and controlled both from
your local area network system and remotely over the internet through
most internet browsers.
This is more than a replacement for the traditional VCR time-lapse
video recorders as there are no video video cassettes to change.
Also your network will be protected from the consequences of high
bandwidth demand of video streaming which results from running only
network cameras over your existing network |
DVR
Software |
 A
DVR software is used to manage a network of cameras and other security
devices on a computer system.
Local and remote configuration, viewing, pan-tilt-zoom control,
recoding, archiving, events and alarm management, etc, are all made
possible by DVR software via a web browser or some licensed application
software.
All Network Camera systems come with in-built software to manage
them. Third-party softwares are also available for enhanced systems
management such as camera touring, scanning, audio-visual alerts,
tamper-proof recording, date/time stamping and multi-up displays
of cameras and other devices like intrusion detection, audio and
lighting units. |
