Solutions & Applications
Factory
Office
In a factory setup, you can connect all analogue video cameras from the production plant, office, warehouse, loading bay into the transmitter installed
in the guard house. Then the security guard can see the live and recorded videos in a video monitor. At the same time, the videos can be transmitted
via the LAN so the managers sitting in the office can also manipulate the video from their own PCs. Also they can monitor the activity inside the
factory from a PDA and the mobile network while they are going out.
Solutions & Applications
Convenience Store
Petrol Station
ATM
For retail chains like convenience stores and petrol stations, the managers in the company’s headquarters can monitor the current activities in every
branches via the Internet. A multi-site monitoring software allows monitoring up to 16 videos from a number of remote sites simultaneously by using
one PC.
Solutions & Applications
Traffic
In the past, traffic monitoring and security in a town centre would usually rely on optical fibre network for transmitting the videos back to the control
room. However the optical fibre network is very expensive to install and to maintain. So the installation of the cameras can only be limited to the
extremely prime area.
From now on, the video cameras installed in the public area can be connected to a VT transmitter and the video signal can be transmitted to a nearby
building via wireless LAN. Then the video data can be relayed to the control room via ADSL. It would significantly reduce the cost of installation and so
these applications can be further expanded to cover more extensive area.

Public IP vs. Private IP addresses
“I can see me, why can’t you?”
Private IP address can only be viewed from within the
local network. Public addresses can be viewed by
anybody on the world wide web.
Basic Explanation of Internet Viewing
For the DVR/Video System to work correctly you need
to make sure customer has sufficient bandwidth.
At the DVR site you need to be concerned about
“upload” speed. Minimum of 500 kbps is suggested.
At the Remote Viewing site you need to be concerned
about “download” speed.
Use site like www.speedtest.net or many other Ping
speed sites.

Pre-Trip Requirements
Determine if customer already has broadband connection.
If they need to order the DSL or Cable broadband service, be aware
that it normally takes a minimum of five days (some closer to 2 weeks
depending on ISP technician workload).
Ensure the Customer orders a Bandwidth service level capable of
supporting their remote viewing expectations.
If possible, suggest a static IP for more reliable remote access.
IP vs analog HD-SDI
IP Camera Systems
• Most popular IP Video
Management Software
(VMS) require annual license
fees.
• IP NVRs can record up to 64
cameras (you can do more
but it is not recommended)
on a single machine.
• IP Cameras are available up
to 5 mp. (some 8 and 10 mp
cameras are actually multiple
2 mp cameras in same
housing)
Analog HD-SDI Systems
• Analog HD-SDI DVRs do
not have any software
maintenance fees.
• Analog HD-SDI DVRs can
be linked via Central
Management System
(CMS) software to display
64 cameras on a single
screen.
• Analog HD-SDI 1080p
(2MP) are sufficient for
90% of all applications.
IP Camera 1080p
2 MegaPixel Sensor
ANALOG HD-SDI 1080p

Applications of Video Monitoring Over IP
The three main application areas targeted can be defined as
following:
E-Surveillance -The merging of the analog and digital worlds is particularly
relevant to surveillance applications, where existing CCTV systems are being
integrated into the IT environment, enriching them with new functions and
greater flexibility at a lower cost.
Web attractions - Posting real-time images on a network (very often the
Internet) is making websites very popular.
Remote monitoring - Enabling processes taking place in your professional
environment (factory, construction work, etc.) to be viewed while working
from home or at your office desk.
There are so many benefits of CCTV system installation.
So people prefer it .
Increased deterrent
Reduced retail theft
Increased detection
Staff protection
Remote monitoring
Reduced fear of crime
Increased professionalism
Receive warnings in advance
Safer working environment
Eliminate fraudulent insurance claims
CCTV Types
( Indoor & OutdoorIP66)
Annex, suggest fiber network for CCTV
Great Distances between devices.
Coax is functional to 1000’ in CCTV applications without amplifier.
Functional to 10,000’ (multimode) i.e. 20 miles (singlemode)
Fiber is easier to install- Light weight & small diameter
Fiber Generates no interference- and nothing interfere with it (EMI & RFI).
System can be easily upgraded in view of future expansions.
Fiber have longer life-No corrosion.
Lower maintenance cost after installation
Security of communication
Much higher data speed.
