CLOSED CIRCUIT TELEVISION SYSTEM (CCTV)

Introduction
Throughout the world, Closed Circuit Television surveillance and observation are now a way of life for many people, whether the systems are at the work place, on motorways, in shopping centres, banks or at sports venues.  Evidence produced by CCTV systems of incidents is being accepted in law courts in many countries. With this expanse in the use of CCTV, the quality of information provided by CCTV is critical.

IVORY SYSTEMS  has been involved in designing and installing Closed Circuit Television (CCTV) Systems for nearly eight years and therefore possess extensive experience and technical expertise in the selection and application of available equipment.

Our design is a modular CCTV system which takes utmost advantage of recent advancements in camera resolution, central monitoring, touch screen control and other recent technologies in professional surveillance developed by Philips CSS, Sky-tracke and VISTA. Philips CSS is a manufacturer with an established reputation for high products amongst corporate CCTV users in the world.

Scope of Proposal

• Design a standard Surveillance system with high levels of functionality and multi-level system security at minimal cost.
• Ensure that the system has straightforward network modification and upgrade and long term compatibility with new developments.
• Design an event monitoring system flexible, easy to operate and absolutely solving the security challenges of our client.
• Ensure that the Surveillance system has facility for user control of real-time features on multiplexed recording playback, fast picture update.

Key Benefits of Solution

• Flexible- Additional Modules and controllers can be added easily to expand the system’s size and capability. Cost effectively manages a range of configurations.
• Cost-effectiveness – Distinctly higher performance and reduced installation and maintenance costs deliver real value for money.
• Simplicity and Ease of Use: The systems are user friendly and do not need a high level of expertise to operate.
• All-Round Support from IVORY SYSTEMS – The high quality systems from IVORY SYSTEMS are backed up with comprehensive maintenance, service and training support. With a wealth of experience in industrial, commercial, leisure and retail applications, communication channels are guaranteed to stay open, and personnel and property remain safe.

Design Considerations

The contexts in which the design process will take place have been defined in two categories:

1. The Client’s requirements
2. The Characteristics of the site

The need for clarity, speed and accuracy of image and information blended with ease of control inspired the design for the Surveillance system. Accordingly, our recommendations are based on the following:

• Size/Complexity of the project
• Flexibility required
• Degree of event management required

The underlying considerations that run throughout the design of these systems include

• Cost effectiveness,
• Adherence to stipulated standards,
• Aesthetics
• Building management and systems integration.

Design Overview

Cameras
Colour digital wide view cameras for external applications and digital dome cameras for indoor use. The wide view cameras are able to cover up to about 50m away at about right angle which is suitable for outdoor applications.

Mounting
All external cameras will be mounted on fixed brackets while indoor cameras are ceiling mounted.

Monitors
These are colour monitors hence consistent with the camera used. Monitoring is achieved via a high performance colour monitor. The proposed monitor offers a high quality video output.

Digital Recorder (DVR / NVR)
All images are continuously recorded so that events can be reviewed if the need arises. Recording is achieved by Digital Video recorders / Network Video recorders which records images of relevant events and stores them on the Hard Disc in the recorder. This makes recorded images much easier to manage.

This device also manages the video information from each of the cameras connected and processes same either to be displayed on an analogue monitor or PC monitor or routed to unto an external or internal archiving medium (e.g. DVD ) for future reference. We have from 4 –channel to 64-channel DVR / NVR based on the site’s requirement.

Control Centre
The control centre is the heart of the system as it houses the Triplex, the Video Recorder and other ancillaries of the system. Control of all equipment is from this centre and an overview of the entire facility can be seen from there.
