Calcutta, March 6 :    Calcutta, March 6:  The winds of liberalisation are sweeping through Lalbazar. Struggling to check the spate of dacoities in apartments, the police are ready to tread the path of privatisation. And Tata-Honeywell, the joint venture company between Tata Industries Ltd and Honeywell Inc. of USA, has already 'impressed' senior police officers with a recent security drill at Lalbazar. 'The technology is really good. I am sure it will help us check crime in the city,' said deputy commissioner, detective department, Banibrata Basu. 'But as this is the first time in the 223-year history of Calcutta Police that we are planning to join hands with a private firm, we will have to await clearance from the government, beside gauging the public response to such a move. So, we have decided to conduct a survey among the people,' he added. 'We are all set to instal the US-based technology in Calcutta, pending clearance from the police,' confirmed Rajarshi Datta, regional support manager, Tata-Honeywell. Explaining the technology, Datta said the entire security system, including the alarm, will be controlled by electronic devices and auto-dial machines linked to master computers through a central monitoring mechanism. The master computer will be set up at the local police station. The security devices, which can be set up at various points inside the house, will remain 'active' when it's empty. In case of a break-in, an alert will flash on the computer screen at the police station. The special security devices include: Door security: A magnetic contact device to be attached to the door-latch. If anyone breaks open the door, the magnetic contact will be cut off, and the alarm will start ringing. A message will instantly be relayed to the master computer installed at the local thana through a micro-processor panel. The message will start flashing on the screen, with the address of the house Window security: A 'glass-break sensor' will be installed at any 'hidden' place in the house. If the window is broken open, the device will 'catch the frequency' and despatch a message to the master computer ntruder security: A sensor capable of detecting any intruder, on the basis of his/her body temperature and alerting the police station Telephone security: A 'tamper switch' which will raise an alarm the moment the telephone wires are snapped, a common ploy of goons Kitchen security: A sensor to detect a gas leak in the kitchen and set off an alarm Videophone: A hidden video camera to be placed above the door-bell. The image of the person at the door will flash on a special screen inside the room Auto-dial system: A message-recording facility to be linked with devices by a control panel. The owner can store four telephone numbers in the system, which will be alerted as soon as an untoward incident occurs Datta said the security-system package will be priced between Rs 9,000 and Rs 25,000, depending on the number of devices to be installed. 'We have chalked out a plan to ask the company to pay us a licence fee. As we will have to keep a watch on the master computer round-the-clock, we will have to increase manpower. We have also told the government to allot more funds for the police budget,' said Basu.
