Telecamera di videosorveglianza DAHUA IPC-HDBW5541E-ZE-27135-S3 5MP IR dome

The DAHUA IPC-HDBW5541E-ZE-27135-S3 is a 5MP IR fixed dome surveillance camera designed for outdoor and indoor video monitoring. It combines a 1/2.7" CMOS sensor with a 2.7–13.5 mm varifocal lens, electronic shutter control and built-in IR illumination to capture detailed images in varied light conditions. The camera includes a built-in microphone, microSD slot (up to 1 TB), RJ45 network port with PoE support and alarm I/O, all housed in a weatherproof white enclosure rated for operation from –30 °C to +60 °C.

Advantages

This DAHUA 5MP IR dome camera delivers high-resolution 2960 × 1668 video for clear identification and monitoring. The varifocal 2.7–13.5 mm lens provides flexible field-of-view adjustment while the low-light sensitivity (minimum 0.0005 Lux) and infrared illumination improve visibility at night. Multiple power options (12 VDC, 24 VAC, PoE 802.3af, ePoE) and on-board storage support up to 1 TB microSD simplify installation and increase deployment choices. Robust operating temperature range and outdoor rating make it suitable for a variety of environments.

Suitable for

• Perimeter and outdoor area surveillance
• Parking lots and access control points
• Building entrances and lobbies
• Retail and commercial premises requiring detailed image capture

How to use

Mount the camera on a stable surface using appropriate anchors for the installation site, orient the varifocal lens to achieve the desired field of view, and secure the housing. Connect power using 12 VDC, 24 VAC, PoE (802.3af) or ePoE and link the camera to the network via the RJ45 port. Insert a microSD card up to 1 TB if local recording is required and configure video, audio and alarm settings through the camera web interface or supported NVR software. Adjust electronic shutter and exposure settings to optimise image quality in different lighting conditions.

Recommendations

For optimal night performance, ensure the IR area is not obstructed and avoid pointing the camera directly at highly reflective surfaces. Use PoE where possible to simplify cabling, and regularly check firmware and NVR compatibility to maintain reliable recording and remote access.
