AI based object tracking, PTZ control and adaptive IR illumination are featured in the new high definition Wisenet X PTZ PLUS cameras by Hanwha Techwin.
Designed for use in perimeter protection and for large open areas such as airports, car parks, industrial estates, stadia and city centres, the new 2MP, 6MP and 4K Wisenet X PTZ PLUS cameras can capture evidence grade images of objects up to a distance of 200 metres regardless of the lighting, the product company says, with adaptive IR (infra-red) which adjusts the angle of the camera’s IR LEDs to match the level of zoom.
At the heart of the new X PTZ PLUS cameras is Wisenet7, Hanwha Techwin’s proprietary chipset. The cameras also have from a Techwin proprietary device certificate issuing system which embeds unique certificates into Wisenet products during the development phase and manufacturing.
Wisenet7 products have ‘extreme’ Wide Dynamic Range (WDR) using Local Contrast Enhancement and Scene Analysis to capture images from scenes containing a challenging mix of bright and dark areas. An AI auto-tracking feature allows control room operators to monitor the movement of objects whilst remaining hands-free to control other cameras. 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.
During their life cycle, most PTZ cameras are likely to be expected to ‘pan and tilt’ many thousands of times and it is not unknown for positioning errors to occur. 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.
Other features:
– wipers remove rain, sleet or snow and then activate a heater on the lens to dry any residual water.
– An extended tilt range of up to 110 degrees ensures that objects positioned above the cameras can be seen.
– Improvements in manual control PTZ functionality makes it much easier for operators to manually 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.
Compact and about 65 per cent lighter than most PTZ domes, the camera-mount installed X PTZ PLUS cameras require engineers during a first fix to just ‘match three points and twist’. This enables them to tighten screws without having to hold onto the camera. Unlike conventional PTZ cameras which require up to five separate cables, the 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.
The new PTZ PLUS cameras are:

-Wisenet XNP-8300RW: 6MP 30x optical zoom PTZ camera
-Wisenet XNP-6400RW: 2MP 40x optical zoom PTZ camera
Uri Guterman, Head of Product & Marketing for Hanwha Techwin Europe, said: “Setting a new standard is a phrase which is often used when products are launched, but I believe it can genuinely be applied to these new cameras. Our highly talented design, development and manufacturing teams have certainly put their expertise to very good use and in doing so, have raised the bar in terms of providing users with the ability to closely monitor and track any suspicious activity or incident.”
