Dallmeier RDF6400DN (12 - 40 mm)

The Dallmeier RDF6400DN sets itself apart from conventional dome cameras through its combination of 4K UHD resolution, a motorized P-Iris varifocal lens with a 12–40 mm range, and true day/night functionality, all housed in an IP66- and IK10-rated enclosure. This makes it suitable for demanding outdoor surveillance where detail and durability are critical.

Highlights

• 4K UHD resolution (3840 x 2160) at up to 30 fps for crisp, detailed images.
• Motorized P-Iris varifocal lens, 12–40 mm, with remote zoom and focus adjustment.
• True day/night with IR cut filter and minimum illumination of 0.05 lux (colour) / 0.01 lux (B/W).
• IP66 weatherproof and IK10 vandal-resistant housing for outdoor use.
• Wide Dynamic Range (WDR) exceeding 120 dB for challenging lighting conditions.
• H.264, H.265, and MJPEG compression for efficient storage and bandwidth use.
• Two-way audio via line in/out and local recording to MicroSDXC card (up to 1 TB).
• Power over Ethernet (PoE, IEEE 802.3at Class 4) or 12 V DC for flexible installation.

In daily use

The RDF6400DN excels in scenarios requiring fine detail over medium to long distances, such as parking lots, perimeters, or building entrances. The motorized lens allows installers to adjust the field of view remotely, reducing the need for manual adjustments at the camera. Its robust construction ensures reliable operation in temperatures from -30 °C to +50 °C, while the integrated IR cut filter automatically switches to black-and-white mode in low light to maintain image clarity.
