The ACTi D91 1 Mp Indoor Mini Dome Camera comes with a built-in 2.93mm lens that captures clear images of the surveillance area. The lens’ 72° horizontal viewing angle allows coverage of a wide area. The 1/4" progressive scan CMOS sensor ensures clear images even of moving objects and thanks to a minimum illumination of 0.1 lux (F2.0), the camera reproduces crisp detail even in dimly lit areas.For real time surveillance, this indoor camera supports a maximum frame rate of 30 fps, and ensures no compromise on the image quality by capturing footage in 1280 x 720p. H.264 high profile and MJPEG compressions ensure reduced file sizes, so you can store more footage in a limited storage space, and allow for optimized utilization of network resources.You can store footage on-board the mini dome camera by inserting a microSDHC card (sold separately) into the provided slot, so no data is lost in case of power or network failure. In addition, the PoE camera can be powered via the network cable itself, eliminating the need for a separate power supply and associated wiring.
