PTZs with AI-Enabled Tracking

by Benchmark

Hanwha Techwin has launched the Wisenet X PTZ PLUS range which incorporates AI based object tracking, precise PTZ control, improved pre-set accuracy, adaptive IR illumination and enhanced cybersecurity. Designed for perimeter protection and large open area applications, the 2MP, 6MP and 4K PTZ cameras are able to capture evidence grade images of objects over distances of 200 metres regardless of the lighting conditions, with the help of adaptive IR technology which adjusts the angle of the camera’s IR LEDs to match the level of zoom.

The cameras make use of the Wisenet7 proprietary chipset which offers technologies to significantly enhance the cameras’ cybersecurity credentials. The cameras also benefit from a proprietary device certificate issuing system which embeds unique certificates during both the development phase and manufacturing process.

Wisenet7 also ensures the capture of high quality images with an extreme wide dynamic range (WDR) feature utilising local contrast enhancement and scene analysis technologies to capture clear images from scenes containing a challenging mix of bright and dark areas.

The AI-enabled auto-tracking feature allows operators to efficiently monitor the movement of objects whilst remaining hands-free. With a right click of a mouse, operators can programme a camera to lock onto and auto-track a specific object. It does so with the help of deep learning video analytics which detects and classifies people and vehicles. The video analytics is supported by AI algorithms unique to Hanwha Techwin.

Wisenet PTZ PLUS cameras, which have a pre-set accuracy of ±0.1 degrees, are able to detect if they are not precisely aimed at the specified field of view and will move within one second to the correct position. Built-in wipers remove rain, sleet or snow and then activate a heater on the lens to dry any residual water. Improvements in manual control make it much easier for operators to zoom to see close up detail of target objects and track their movement. A focus save function, which can be applied to 32 pre-defined areas, ensures that regardless of the lighting conditions, a camera is able to rapidly come into focus when it is moved to a new position.

The camera mount can be quickly and easily deployed, requiring engineers during a first fix to match 3 points and twist. This conveniently enables them to tighten screws without having to hold onto the camera. Unlike conventional PTZ cameras which require up to 5 separate cables, the Wisenet X PTZ PLUS only needs a single RJ45 cable to operate and this is installed with a flexible bush to ensure the camera is waterproof.
