Description

The Dahua IPC-HDBW2831R-ZAS-S2 8MP 4K Lite Dome Network Camera delivers superior video performance and advanced surveillance features for professional security applications. Powered by a 1/2.7″ CMOS image sensor, it provides crisp 4K ultra-high-definition footage at up to 15fps and smooth 2688×1520 resolution at 25/30fps.

Equipped with Smart H.265/H.264 compression technology, the camera reduces bandwidth and storage needs without compromising video quality. Its built-in IR LEDs deliver up to 40m night vision, while starlight technology ensures clear, vibrant images even in low-light environments.

With support for intelligent video analytics (IVS) including tripwire and intrusion detection, plus abnormality alarms such as motion detection, tampering, and SD card errors, this camera enhances security monitoring and response efficiency.

The robust IP67 weatherproof and IK10 vandal-resistant housing makes it ideal for both indoor and outdoor installations. Power options include 12V DC or PoE for flexible setup. Additional features include audio I/O, alarm I/O, Micro SD card support (up to 256GB), WDR, 3D DNR, BLC, and HLC for superior adaptability across environments.
