A prototype of the drone to be used by Kolkata Police
Kolkata: Kolkata Police is gearing up for major high-tech procurements, inviting tenders for heavy-duty drones and encrypted digital radio sets worth nearly Rs 3.9 crore to modernise city surveillance and emergency communications. The force has floated an e-tender valued at a little more than Rs 1 crore to procure two unmanned aerial vehicles (UAV) alongside specialized training for 12 to 15 police ‘pilots’. The new handsets feature built-in GPS units accurate to within 10 m, allowing central control rooms to track patrolling officers in real time. Weighing under 475g with 10-hour battery cycles, the radios also feature high circuit protection, ensuring communication remains uninterrupted even if the antenna gets damaged.
Unlike older radios that have static distortion, these new devices transmit compressed, encrypted binary data packets using time division multiple access technology. This ensures crystal-clear audio during emergency responses and prevents unauthorized eavesdropping.
