The DS-2AE4223T-A3 is a TurboHD 2 MP indoor PTZ dome camera provides high definition analog output up to 1080p. TurboHD means that the analog signal can be sent over existing coaxial cable, eliminating the need to run new cables for high definition video. The 4 mm to 92mm 23x lens allows the correct angle of view to fit any situation. Digital WDR (Wide Dynamic Range) ensures images will be optimal, no matter what the lighting conditions. The camera also features a range of Smart functions, including line crossing, intrusion, and region entrance and exit, benefitting users with great improvements on security efficiency and, more importantly, with key events and objects being recorded for further forensic needs.
