The DHD80/36RW-T-M can capture 4k footage and offer up to 50m IR with a built-in microphone to utilise the audio over co-ax. Feature with compatible recorders.
Audio over co-ax allows the camera to transmit audio picked up from its built-in microphone and transmit this over the came co-ax cable as the video transmission. An audio over co-ax compatible recorder is required to fully utilise this function and would allow audio on each channel an audio over co-ax camera is on.
Due to the sensitivity of these cameras you may occasionally get some interference from the power supply. We recommend that you use either a 3amp ungrounded power supply or, if using a box power supply, one of the dedicated isolators.
