The Dahua HDCVI Active Deterrence Series adds a warning light and siren to an HDCVI camera, so it can actively warn off intruders as well as record them. Alarms are sent back to the recorder over the same coax cable. The range includes TiOC, Active Deterrence 2.0 and PIR models. In Dahua model codes, these are the HAC-ME cameras.

The Active Deterrence Series cameras we list are below. See also our Dahua TiOC and active deterrence range, or compare the other Dahua HDCVI series.
