Dahua Adds 2MP P/T/Z Cameras With H.265 to Pro Series, Ultra Series

The IP-based cameras offer an ultra low-light, 2-megapixel sensor, wide dynamic range (WDR), Starlight technology and backwards-compatible compression options.

IRVINE, California — Dahua Technology USA has added five new mid-to-long range pan/tilt/zoom (p/t/z) cameras to its Pro Series and Ultra Series. The network cameras feature an ultra low-light, 2-megapixel sensor, wide dynamic range (WDR), Starlight technology and backwards-compatible compression options.

P/T/Z cameras are widely used for applications that require real-time tracking of people or vehicles with an appropriate level of zoom to identify fine details up close. The continuous movement that p/t/z models endure requires more bandwidth than a stationary camera. Dahua’s new 2MP p/t/z cameras offer H.265 for improved encoding efficiency while preserving high-quality video, according to the company. H.265 is said to save up to 50% on bandwidth and storage when compared to standard H.264. The cameras also support MJPEG and H.264 for backwards compatibility.

“These new additions to Dahua’s portfolio have the latest compression standard, but for systems that are not yet ready for an upgrade to H.265, the cameras are also compatible with previous codecs,” says Jennifer Hackenburg, senior product marketing manager, Dahua. “In this way, the end user’s investment in their video surveillance system is maximized, because they can transition to the new codec whenever they’re ready. It’s as simple as flipping a switch.”

The new Pro Series mini-p/t/z is offered at a cost-effective price point, offers ease of installation, and has IR illumination and a 25x optical zoom lens, according to the company. Three of the new Pro Series p/t/z models feature a 30x zoom, true WDR, and auto-tracking functionality. Dahua says this allows the camera to follow a subject automatically without the need of an operator. The new Ultra Series p/t/z features a resilient metal housing for tough environments, auto-tracking, a 40x optical zoom lens, and an IR distance of up to 200m (656.7 feet).

With ultra-low light Starlight technology, all five p/t/z models deliver enhanced detailed surveillance in nighttime scenes, the company states. By balancing light throughout the scene, Starlight allows for detail to be captured in low light at illumination down to 0.005 lux.

Additionally, Intelligent Video System (IVS) analytics allow the cameras to quickly and accurately respond to monitoring events in a specific area, Dahua states, including tripwire violations, intrusion detection and detection of abandoned or missing objects.
