 Closed
Circuit Television Systems, popularly known
as CCTV systems are widely used in almost all
the industries for various purposes. These CCTV
systems are common in nature as far as their installation
is concerned except in potentially Hazardous Areas.
It has proved beyond doubt that the CCTV systems
play vital role in the safety, process control, overall
supervision, watch & ward etc; and as per any individual's
intention or liking. There are various types of CCTV
systems ranging from simple monitoring to recording
the events for a number of days from minute to minute
as per the set-up for a wide range of cameras. The information
so available is effectively used in diagnosing the itching
problems.

However,
in potentially hazardous areas, normal CCTV Systems
cannot be used, as these are available. The equipments,
like CCTV camera, Zoom Lenses, Pan & Tilt
Head (Scanners), Monitors etc; are required to be enclosed
in a Explosion proof, Flameproof Enclosures which are
Weatherproof too. For this, site conditions and potentially
hazardous Zones predominantly come in the picture while
selecting the equipment. It is possible to select proper
system to monitor each and every site of the above referred
Plants or Establishments. During last decade or so,
we have designed the equipment for utilizing them in
Zone- 1 and Zone-2 for Gas Group-I , IIA, IIB &
IIC. The equipments have been supplied and successfully
installed in Refineries, Petro Chemical Plants and Defense
establishments during last decade. The Flameproof, Explosion
proof Enclosures for the CCTV equipments for
the Hazardous Areas are custom built and number of Accessories
can be added depending upon site requirements. Monitoring
of various areas which are inaccessible to persons during
the actual operation of the plant or where it is not
possible to depute a personnel for getting the on the
spot information which is vital, CCTV systems
are quite useful.

Flame
proof, Explosion proof, CCTV system equipments are designed
and manufactured as per IS: 2148 (1981) for Zone 1 &
Zone 2 for Fas Group I,IIA, IIB and Group IIC. These
equipments are with weather proof protection as per
IS: 13947 (Part 1, 1993) and also conforming to IS:
13346 (1992) for General Design, Rating and Performance.
|
|
The
Equipments have been Tested and Certified by Central
Mining Research Institute (CMRI) for Flameproof, Explosion
proof and Weatherproof construction as per Indian Standards
mentioned above. The Equipments are also certified and
approved by Bureau of Indian Standards (ISI Mark) as
per the Licence: - CM/L - 7336674 . The equipments have
approvals from CCOE (Chief Controllers of Explosives,
Nagpur) and D.G. F. A.S. L. I.

CCTV
SYSTEMS FOR STEEL PLANTS, CEMENT & CHEMICAL PLANTS
:-
|
|
In
Steel and cement plants CCTV system needs special
attention to the enclosures in which CCTV cameras
are designed because of generation of high temperature
of the processes invoved. This refers to Slab Caster
Bloom Caster and Furnaces. The CCTV systems have
proved quite useful in these manufacturing shops in
a number of ways. In Chemical Plants too where the temperature
is above normal, it is advisable to use water cooling
jackets ( WCJ). These WCJs not only maintain healthy
temperature surrounding the camera. Which is enclosed
in the WCJ, but also protects from any chemical reaction
arising out of manufacturing processes.
