Dahua Releases New Cameras With Night Color Technology, Enhanced PoE

Dahua’s night color technology network dome and bullet cameras do not require external IR or white-light illumination.

IRVINE, Calif. — Dahua Technology announces the addition on two new cameras to its eco-friendly, patented enhanced Power over Ethernet (ePoE) product family.

The DH-IPC-HFW4239TN-ASE 2MP fixed bullet and the DH-IPC-HDBW4239RN-ASE 2MP fixed dome utilize Dahua night color technology, using a high-performance sensor and ISP and an achromatic, large aperture lens (F1.0), which is said to produce crisp, clear color images in low-light environments.

Dahua says this light-sensitive technology allows the camera to remain in color mode and to capture more available light to reproduce color images with superior detail and contrast in applications with at least 1 lux of ambient or artificial light.

Night color technology cameras are recommended for applications where saturated, full-color images are produced in very low ambient light applications.

The achromatic lens coupled with a large aperture is far superior to a traditional lens used in surveillance cameras for multi-color “white-light” imaging, according to the company.

Dahua’s night color technology network dome and bullet cameras do not require external IR or white-light illumination. Night color technology is said to consume 1/3 to 1/2 of the wattage required by cameras with IR illumination.

The cameras also incorporate back-illuminated pixel technology and a 1/2.8-inch STARVIS CMOS sensor to deliver clear color images suitable for identification-level monitoring.

“Our two new night color technology ePoE cameras are high-performing solutions made for low-light deployments,” says Jennifer Hackenburg, senior product manager at Dahua North America. “With many very low light scenarios requiring the ability to identify the color of clothing or a vehicle, this new camera not only provides full color in very low-light, it requires no LEDs or IR cut filter, making the entire solution more cost-effective and power-saving.”

In addition to low-light performance, the night color technology cameras feature Dahua’s enhanced PoE technology, a plug-and-play solution that transmits power and data over long distances via Ethernet or coaxial cables.

ePoE technology uses advanced modulation to transmit video, data and power up to 800 m (2624 ft) at 10 Mbps via a single CAT5E cable or up to 1,000 m (3281 ft) via a standard RG59 coaxial cable, according to the company.

For video security and surveillance installers, Dahua says ePoE technology saves time and money by reducing overall cabling requirements, allowing for existing coaxial cable to be used and minimizing the number of peripheral devices needed. For new installations, ePoE offers the ability to design long-distance applications without the need for additional repeaters.
