Câmara de vigilância dome IP Dahua WizSense IPC-HDBW3849E-AS-IL — 3840×2160, montagem no teto, com fios, preto

The Dahua Technology WizSense IPC-HDBW3849E-AS-IL is an 8MP fixed-focal dome IP security camera designed for ceiling installation in indoor and outdoor environments. It uses a 1/2.7" CMOS sensor to deliver up to 3840 x 2160 resolution at 25/30 fps, supports wired Ethernet connectivity and offers night-vision capabilities with IR and warm light illumination to improve image capture in low-light conditions.

Advantages

The camera provides high-resolution 8 MP imaging with H.265 compression for lower bandwidth and storage use. Built-in IR LEDs and warm light extend visibility up to 30 m, while WDR, 3D noise reduction and other image enhancements support a range of monitoring scenes. It includes intelligent analytics (intrusion, tripwire, human/vehicle classification, face detection) and multiple alarm and audio interfaces, plus robust environmental protection (IP67, IK10) for reliable indoor and outdoor operation.

Suitable for

• Ceiling-mounted surveillance of retail stores and shopping areas
• Perimeter and entrance monitoring of office buildings
• Parking garages and lot monitoring with night-time requirements
• Public spaces where vandal resistance and weather protection are required

How to use

Mount the dome camera on a suitable ceiling surface using the manufacturer’s mounting template and hardware. Connect the camera to a network via wired Ethernet and provide power either through a 12 V DC adapter or PoE. Configure resolution, frame rate and compression settings in the camera web interface or management software to match available bandwidth and storage. Enable intelligent detection rules (intrusion, tripwire, face detection) and set sensitivity levels and notification preferences. Insert a compatible microSD card if local recording is required and verify night-vision operation in low-light conditions.

Recommendations

Place the camera where its 355° horizontal viewing coverage and 58° vertical field of view are suitable for the monitored area. For reliable night-time detection, position the camera so warm light and IR illumination cover critical zones; adjust SMD area settings to limit warm-light-triggered alarms. Use PoE for simpler installation and consider periodic inspection of seals and mounts to maintain IP67/IK10 protection.
