If you have seen anything like this when you were crossing through streets of Dhaka in last few days, don’t be confused. If you thought that a new set of lucrative street lamps are installed, you are wrong. Actually when you looked at it, it might also examining you for any kinds of suspicion. Because it is a CCTV camera. The Dhaka Metropolitan Police decided to install the digital surveillance system for traffic management and crime control, setting up a unified control room. As a result, number of cameras is installed at Mohakhali, Nabisco mor, Shat Rasta mor, Karwanbazar and other important places.
The lamp shaped Black unit is the camera; the white box on top of it contains the power/ supporting units and topmost white unit is the wireless radio to connect the camera with a base station which is again connected to the control room. Wireless Network is done by Motorola Canopy AP-SM (Access point – Subscriber module) system. Motorola uses the ideal technology for making delivery of high-demand technologies like internet access, voice over IP, video services, and security surveillance much quicker and much less expensive. Canopy has been widely used in Bangladesh for past few years by wireless ISP’s for providing Last Mile solution. Initially Banglalink, one of the GSM operators,also used canopy for backbone connectivity to their base stations which were later replaced by Microwave and optical fiber.
