We are planning to instal a DIGITAL
WIRELESS NETWORK in central zone as this zone is the
focus for agitational rogrammes and VIP movements. This
will be for the 1st time in police department in india.
Comprises of
a). A repeater at Naubath pahad.
b). Receiver station at DCP central zone office.
c). 5 important locations identified to set up towers
and cameras, namely Secretariat, Assembly, Abidis, Indira
park, RTC 'X' roads.
d). DCP, 3 ACPs can watch all events going on from their
office and zoom, pan & tilt any of the cameras.
The cost of this Project is about RS. 52 Lakhs.
The Digital transmissions are superior to analog
transmissions because no overlapping of signals, signals
can be controlled by coding and decoding systems, the
number of points / antennas / control can be increased
as desired, video conferencing, recording and many other
facilities can be added on.
Brief Comparison
between Wireless Link and Fibre Optics
- Cost : 1km of fibre optic of 2 mbps Bandwidth costs
Rs. 10 lakhs for 1 km. Rental for the same 1 km. of
fibre will be Rs. 20,000 per anuum. 2 mbps Bandwidth
is required for video transmission.
- Fibre optics as a one time investment on the proposed
project is too high (10crores) on rental basis it
would incur a cost of Rs.10 lakh per annam only for
the fibre, all other material will cost extra.
- We become totally dependent on the fibre optic
supplier for services offered for operation &
maintenance.
- Relocation, mobile monitoring ( in our vehicles),
remote contrl are not easy or possible in fibre optics.
