Dahua USA launches three-in-one camera

Dahua Technology has announced the release of a Three-in-One Camera (TiOC) for its North America market, built to deter unwanted behaviour in three different ways. With warm-light LEDs, an active alarm with red and blue flashing lights, and two-way talk, the TiOC helps security operators take a proactive approach and stop incidents before they occur.

These features are referred to in shorthand as “lights, camera, action,” says Jennifer Hackenburg, product marketing director at Dahua USA. “The camera helps our customers direct security operations in an active way while decreasing the need for on-site personnel.”

Where traditional security cameras may struggle to render usable video at night, the TiOC reportedly solves this issue with Smart Illumination. When integrated with Smart Motion Detection, this means that the camera’s warm-light illuminators turn on when a target appears in a defined monitoring area. The camera then records in full colour for as long as a target appears, with the LEDs acting as illumination for the recording as well as a deterrent to undesired activity. When a target stops, the LEDs switch off and the camera goes back into IR mode. “Using LEDs only when there is target reduces light pollution as well,” Hackenburg added.

If a target passes from a monitoring area into a “rule area” – a more narrowly defined area of interest – the TiOC’s active alarm feature is triggered. A siren sounds and red and blue lights flash to further deter the intruder. At this point, a prerecorded or custom message can be played through the camera’s speaker, or a security operator can use the two-way talk feature to speak to the intruder. Dahua developed new technology to improve the audio quality of this feature.

“Our VoiceCatcher technology is made up of a dual microphone that picks up audio at a greater distance – seven metres – than a traditional single microphone,” commented Hackenburg, “And our proprietary noise reduction algorithm reduces background noise such as wind.”

Other features of the TiOC include 4MP resolution, a 2.8mm fixed lens, Smart H.264+ and Smart H.265+ dual codec, triple-stream encoding, and Starlight technology. The camera is rugged as well, with an IP67 rating and ArcticPro functionality that lets the camera operate in temperatures down to -40°F.
