PoE Extender domes
The new Wisenet PoE extender cameras, pictured, are designed to save installers time and money when fitting two cameras within 80 metres of each other.
For retrofit applications where an additional camera is needed, system integrators need to simply substitute a Wisenet camera with a PoE Extender camera, and then re-install it at the new camera location, with both devices being able to share the same cable run. Able to support all PoE cameras in the Wisenet range, the new 2 and 5 megapixel PoE Extender indoor and outdoor dome cameras provide a solution for new installations, the makers say, as they reduce the number of network ports and switches, as well as the amount of cabling, required.
The installer also has the option to connect other PoE enabled devices to the Wisenet PoE extender cameras, such as a supplementary lighting unit, I/O controller or PIR sensor.
The four new domes all have built-in infra-red LEDs which illuminate objects up to 50m from the camera and feature Digital Image Stabilisation (DIS) which helps towards sharp, stable images by reducing motion blur as caused by wind or vibration, the manufacturer says. All products come with Wide Dynamic Range (WDR); the 2 megapixel models performing at up to 150dB and the 5 megapixel models at up to 120dB, to produce images from scenes containing a mix of bright and dark areas, which normally results in over-exposed or under-exposed images.
Part of the Wisenet X Plus series, these cameras feature magnets which lock sensor modules into the dome housing. A waterproof gland, through which a network cable can be inserted with an RJ45 plastic push-through device, negates the need to re-make a cable end. Before installation, technicians can configure IP network settings without the need to remove a camera module from its packaging,
The new cameras come with license-free specialist analytics such as directional detection, virtual line, enter/exit, appear/disappear and loitering detection. An audio analysis function is able to recognise critical sounds, such as explosions, screams and broken glass, and then generates an alert to enable emergency services to react.
The processing power of the chipset at the heart of the new cameras enables them to support edge-based people counting, heatmap and queue management applications. These are for use by retailers, art galleries and museums for understanding of customer behaviour and improve productivity, with the option to display the captured data on the centralised dashboard of the Wisenet Retail Insight (v2.0) business intelligence solution.
如图所示，新的Wisenet PoE扩展摄像机被设计用于在彼此相距80米的范围内安装两个摄像机时，可以节省安装人员的时间和安装成本。
对于需要附加摄像头的翻新应用，系统集成商只需将Wisenet摄像机简单地替换为PoE Extender摄像机，然后将其重新安装在新的摄像机位置，此时，两个设备就可以共享同一条电缆。制造商表示，新的2百万和5百万像素PoE扩展室内和室外半球型摄像机能够支持Wisenet范围内的所有PoE摄像机，它们为新安装提供了解决方案，该方案可以减少网络端口和交换机的数量以及所需的电缆数量。
安装程序还可以选择将其他支持PoE的设备连接到Wisenet PoE扩展摄像机，例如辅助照明单元，I / O控制器或PIR传感器。
这四个新半球型摄像机均具有内置的红外LED，最远可照亮50m外的物体，并具有数字图像稳定（DIS）功能，可通过减少由风或振动引起的运动模糊来帮助获得清晰，稳定的图像。所有产品均具有宽动态范围（WDR）；2百万像素型号的性能高达150dB，5百万素型号型的性能高达120dB，以从包含明暗区域混合的场景中生成图像，而通常这种情况会导致图像曝光过度或曝光不足。
这些摄像机是Wisenet X Plus系列的一部分，其磁性将传感器模块锁定在球罩中。防水压盖可用于将网络电缆与RJ45 plastic 嵌入式设备一起嵌入，从而无需重新制作电缆末端。在安装之前，技术人员可以配置IP网络设置，而无需从包装中取出摄像头模块，
新的摄像机具有免许可证的专业分析功能，例如方向检测，虚拟线路，进入/退出，出现/消失和游荡检测。音频分析功能能够识别关键声音，例如爆炸，尖叫声和碎玻璃，然后生成警报以使紧急服务能够做出反应。
新型摄像机核心的芯片组的处理能力使它们能够支持基于边缘的人员计数，热图和队列管理应用程序。这些供零售商，美术馆和博物馆使用，以了解客户行为并提高效率，而且还可以选择将捕获的数据显示在Wisenet Retail Insight（v2.0）商业智能解决方案的集中式仪表板上。
