Upgrading analogue to IP

The Special Branch, or SB, is the prime intelligence agency of Bangladesh. This is the only intelligence outfit of Bangladesh which works in all strategic, operational, and tactical levels. Some people threw bomb in Special Branch (SB) headquarters premises situated in Malibagh, Dhaka, Bangladesh, during a strike throughout the country.

The existing analogue CCTV system they utilised was unable to find out the culprit. SB authority therefore turned to a partner of LILIN – AA Technology Ltd, a professional CCTV solution provider in Bangladesh, to upgrade to a high resolution IP surveillance system. AA Technology Ltd showed SB security team the IP surveillance system by LILIN, which they liked so much and decided to deploy LILIN system at SB.
