Wisenet X PTZ PLUS cameras
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-9300RW, pictured: 4K 30x optical zoom PTZ camera
– Wisenet XNP-8300RW: 6MP 30x optical zoom PTZ camera
– Wisenet XNP-6400RW: 2MP 40x optical zoom PTZ camera
Hanwha Techwin公司的新型高清Wisenet X PTZ PLUS摄像机具有基于AI的目标跟踪、PTZ控制和自适应红外照明功能。
新型2MP，6MP和4K Wisenet X PTZ PLUS摄像机专为周界保护和大型空旷区域（如机场，停车场，工业区，体育场和城市中心）而设计，该公司表示不论光线如何，都可以捕获远达200米外目标的证据品质级别的图像，并带有自适应IR（红外），该红外IR可以调节摄像机的IR
LED灯的角度以匹配变焦级别。
新X PTZ PLUS摄像机的核心是Hanwha Techwin的专有芯片组Wisenet7。摄像机还具有Techwin专有的设备证书发布系统，该系统在开发和制造阶段将独特的证书嵌入到Wisenet产品中。
Wisenet7产品具有“极高”的宽动态范围（WDR），可使用局部对比度增强和场景分析功能从场景中捕获具有挑战性的明暗区域混合的图像。AI自动跟踪功能使控制室操作员可以
监控物体的运动，而无需动手就能控制其他摄像机。只需单击鼠标，操作员即可对摄像机进行编程，以锁定并自动跟踪特定目标。它是借助深度学习视频分析来实现的，该视频分析可以对人员和车辆进行检测和分类。视频分析由Hanwha Techwin独有的AI算法支持。
在其整个生命周期中，大多数PTZ摄像机可能会发生数千次“平移和倾斜”，并且不会发生定位错误。预设精度为±0.1度的Wisenet PTZ PLUS摄像机能够检测到它们是否未精确对准指定的视野，并将在一秒钟内移动到正确的位置。
其他功能包括：
–刮水器去除雨水，雨夹雪或雪，然后启动
镜头上的加热器以蒸发残留的水。
–高达110度的扩展倾斜范围确保可以看到位于摄像机上方的物体。
–手动控制的改进PTZ功能使操作员更容易手动缩放以查看目标对象的细节并跟踪其运动。
–聚焦保存功能可应用于32个预定义区域，可确保无论光照条件如何，摄像机移动到新位置时都能迅速聚焦。
紧凑型且比大多数PTZ球型摄像机轻约65％，安装在摄像机上的X PTZ PLUS摄像机在首次安装时要求工程师仅“匹配三点并扭转”。这样一来，他们就可以拧紧螺丝，而不必固定在相机上。与传统的PTZ摄像机最多需要五根单独的电缆不同，X PTZ PLUS只需要一根RJ45电缆即可运行，并且安装有灵活的衬套以确保摄像机的防水性。
新的PTZ PLUS摄像机包括：
– Wisenet XNP-9300RW，如图：4K 30倍光学变焦PTZ摄像机
– Wisenet XNP-8300RW：6MP 30倍光学变焦PTZ摄像机
– Wisenet XNP-6400RW：2MP 40倍光学变焦PTZ摄像机
