Mumbai Blast & CCTV.

Mumbai Blast & CCTV.

13 Jul 2011 Another Bomb Blast occurred in the centre of Mumbai (Maharashtra, India) at Dadar, Opera House and Zaveri Bazar. That day approximately 18 People killed and 131 injured, now investigation is going on. That day every TV Channel talked about CCTV because most of the blast area had CCTV cameras. But still most of the people don't know any thing about CCTV. Sum People told me to write about CCTV so this post is for them. I already wrote my opinion about blast (14/07/2011) on my face book wall (facebook.com/Shaju Thresiamma). But that was a Hindi – English language.

         

Now we need to check what is CCTV, it means Closed Circuit Television. This System have three main equipments Camera, Monitor and Recorder, Camera will transmit a signal to monitor and recording. Then a security officer will check that visuals and monitoring that place. If there is anything wrong happening in frond of the camera then this officer will inform Police, authority or mobile squad. Then they will catch that person and recorded visuals are evidence for this crime, this is the use of CCTV. If you wand we can send camera signal more than 1KM. But for this we need to fix sum extra equipments also (eg. Modulator and Demodulator or equivalent) and we need to make a good plan before fix CCTV. Anyway I don't wand explain technical side, all developed Countries are using CCTV for security.

These days two types of CCTV Cameras are available in International market, one is fixed camera and other one is moving camera (small internal camera also available for different use.). Fixed camera only shows what is going on in frond of that. But moving camera can move 180 Degree left and right, up and down (Pan-Tilt) and this have Zoom in and Zoom out facility also. It will move 180 Degree 24 hours and if you wand you can stop where you wand and you can focus a place or particular item. That means if your camera is far away from a place then also you can Zoon in (near) and Zoom out that place or person. But don't think for this you need to go near that camera, this all controls are available near security officer table.

         

According to TV Channels Mumbai blast location cameras are fixed cameras. My opinion is better we should fix one moving camera also with 4-5 fixed cameras. For example one security officer need to know what is going on in frond of a particular 'Building'. Then we need to fix one fixed camera in frond of that building but that camera will show only what happening in frond of that building. It will never show what is happening at left and right building. In this case we need to fix two more cameras if you wand monitor that buildings. This way we fixed 5 cameras in frond of five buildings. One day sum one blasted camera no 3, security officer only knows camera no 3 is 'dead' or sum thing happened. But he never knows how that happened until he visits that location. If you fixed a secret moving camera opposite that building from height, then (that will monitor all fixed cameras and that area) that security officer can move that camera and he will understand what happening in damage camera location. I hope our Engineers and Police officers will solve our security lapses.

          One thing I am sure who are behind this bomb blast they knows there is cameras, they checked our security. Then we should show them our ability and we should appreciate Mumbai people for their self-confidence. I hope our special investigation team is doing best investigation.
