Dahua IPC-HDW2231T-AS-S2 is the latest Audio CCTV Camera released by Dahua with an in-built microphone. Some of its features are 2MP, 1/2.8” CMOS image sensor, low illuminance, high image definition, Outputs max. 2MP (1920 × 1080) @25/30 fps, H.265 codec, high compression rate, ultra-low bit rate, Built-in IR LED, max. IR distance: 30 m
The new voice over coaxial technology enables the Dahua audio camera to transmit audio/video signals through the coaxial cable, thereby eliminating the need to run a separate cable for the audio signal
