Common questions
What does WizSense mean?
Dahua says WizSense is its series of AI products using an independent AI chip and deep learning, focused on human and vehicle detection. See our guide to Dahua WizSense cameras.
Does it have night vision?
Yes. It has 3 built-in IR LEDs with a range of up to 30m, and Dahua lists 0.007 lux at F1.4 in colour, 0.0007 lux in black and white and 0 lux with the illuminator on. Dahua says the WizSense 3 Series uses starlight technology and a large aperture lens for clear images in poor light; see our guide to Dahua Starlight low-light cameras.
Is it a weatherproof camera?
Yes. Dahua lists IP67 against dust and water and IK10 for impact in a metal housing, so it can be fitted outside as an outdoor CCTV camera or outdoor security camera. With 3 IR LEDs reaching 30m it is also an infrared camera for night-time coverage.
Is it vandal-resistant?
The metal housing is rated IK10 for impact: Dahua says it can take more than 5 punches from a 5 kg hammer falling from 40 cm (20 J). It is IP67 rated against dust and water.
How is it powered?
From PoE (802.3af) or 12 VDC. Dahua says the camera allows a ±30% input voltage tolerance for some power supplies.
Does it have audio and alarm connections?
Yes. Dahua lists 1 audio input and 1 audio output (RCA) and 1 alarm input and 1 alarm output for the -AS version, and the camera has a built-in microphone.
Is there a 3.6mm version?
Dahua lists the IPC-HDBW3841E-AS-S2 with 2.8 mm and 3.6 mm lenses. This listing is the 2.8mm version, with a horizontal field of view of 107°; the 3.6mm gives 84°.
Which recorder should I use?
It supports ONVIF Profile S, G and T, so it can be added to recorders and software that support ONVIF. Dahua says Quick Pick is available with an AI NVR. See our network video recorders, and use a PoE switch for power if the recorder has no PoE ports.
