Dahua HFW2831S-S-S2 IP bullet camera with 8MP 4K resolution, equipped with the latest H.265+ compression technology, IR LED and intelligent object detection.


The Dahua bullet camera meets the highest requirements of professional video surveillance! Thanks to the high-resolution 8-megapixel sensor, it is possible to detect even the smallest details!

With the improved H.265 encoding technology, the Dahua series network camera has efficient video encoding that saves bandwidth and storage space.

This IP bullet camera uses the latest Starlight technology and shows excellent colour images even in low light conditions.

The camera supports SD card recording and is IP65 rated for extreme outdoor use.



High detail even in complete darkness

With the Bullet IP camera, you get clear and detailed images both during the day and at night: The integrated high-performance LEDs emit light in the infrared range. Invisible to the human eye, the scene is as bright as day for the camera sensor. Since the infrared spectrum is above our visible spectrum and thus also above the colour spectrum, videos are displayed in black and white.

The range of the built-in IR LED is approx. 30 metres.




With advanced Wide Dynamic Range (WDR) technology, the Dahua IP bullet camera delivers clear details in environments with high brightness contrast.

The bright and dark areas can also deliver clear video in bright or backlit environments.



Internet Security

The Dahua IP Bullet Camera is equipped with a number of important security technologies, such as security authentication and authorisation, access control, trust protection, encrypted transmission and encrypted storage, to enhance security defence and data protection and prevent third-party programs from causing damage to the camera.



Alarm when motion is detected

There are 4 fields whose size and sensitivity can be freely set, for example, to trigger an alarm when motion is detected and send a push message to the owner. By selecting the fields, you can also exclude zones from motion detection when passing vehicles, trees or bushes trigger an alarm.



Alarming with video analysis

Zones and lines are available to trigger an alarm when objects cross a line (trigger) or enter a zone (intrusion).
