During last few years, G-APDs (i.e Geiger-mode Avalanche Photo-diodes or Silicon Photo-multiplier s) have emerged as viable photo-sensors for ground based very high energy gamma ray telescopes. They are expected to replace conventional Photomultiplier Tubes due to their superior qualities. Last few years, our group has been engaged in the design and development of G-APD based imaging camera for 4m class telescope. This camera, consisting of 256 pixels, will be installed on a telescope operated by BARC. This telescope will be installed at Hanle in Ladakh in few years’ time and will be dedicated for observations of blazar class active galactic nuclei. Various features of the camera, current status and future plans will be discussed.
