Tamil Nadu police department CCTV recordings distributed storage

distributed-storage

Hello Sir,

In verge of twin murder by police in Sathankulam, I would like
to bring to your notice that the need of the hour is to establish
live streaming of every police station CCTV to a centralized
monitoring facility most propably SP Office

The thought of superior officers monitoring them will deter the
subordinates from getting involved in illegal activities like the
one that happened in Sathankulam

In addition to live streaming we may have to make arrangements to
store all the CCTV recording in cetralized location most propably
SP Office. By doing this in future we will never ever lose any CCTV
recording neither unintentionally nor intentionally as we lost in
Sathankulam case

Regards the cost estimate I have done a market analysis and arrived
at rought figure of 10 Crore for implementing all the infrastucture
discussed in this letter. Total fund allocated to Police Department 
in 2020 budget 8876.57 Crore. Hence the estimate for these 
imrpovement account only for just a mere fraction of 0.1 percent

I have also analysed the technical feasiblity to implement a 
failure detection system. This is also very much posible at 
affordable cost. With this failure detection system (FDS) in place
any single camera which stops sending recording will be imedietly 
notified. This failute detection sytem can be implemented in 50L 
to 1Crore INR

We can also introduce image processing mecahnism (IPM) which will
generate text based timeline of events happening. You can imagine 
this like as video-to-text conversion mecahnism. Say for example if 
any person enters the camera frame at 11:00 AM on 01/Jan/2021 then
the IPM will generate a message line "11:00:53 01/Jan/2021 CAM01 
new person identified" 

With IPM we don't have to sit and watch hours and hours of video
to find any particular event. Just you can do a text seach. We can
even go to extent of implementing facial recognition (China is 
already doing this) and verify against Aadhar. This can also be
done at a affordable cost of 50L to 1Crore INR

Regards,
Dinesh
