Part of the Gen2 extension of the IceCube Neutrino Observatory at the geographic South Pole is a surface air shower detector. Primary goal is to veto atmospheric muons and neutrinos as background for the measurement of astrophysical neutrinos. One possible technology are compact imaging air Cherenkov telescopes, IceAct, that exhibit a lower energy threshold compared to surface particle detectors. The IceAct telescope design is adapted from the FAMOUS fluorescence telescope which achieves a large field of view. It consists of a Fresnel lens allowing for an enclosed optical system protecting the camera from the harsh environment. The camera is based on light collecting Winston cones and SiPMs allowing a high duty cycle. Here we will present the development of a new 61-pixel camera that is intended to replace the 7-pixel camera, currently operating with an IceAct prototype at the South Pole.
