CZ637 System Overiew

Featuring powerful optical zoom and accurate pan/tilt/zoom performance, CZ637 explosion proof PTZ speed dome camera can provide large monitoring range and great detail. CZ637 explosion proof PTZ speed dome camera has very excellent low light performance due to adopting the latest starlight technology. The camera is equipped with smooth control, high quality image and good protection, which make it can meet most of the requirements of video surveillance applications.


Starlight Technology

For challenging low-light applications, starlight Ultra-low Light technology offers best-in-class light sensitivity, capturing color details in low light down to 0.005lux. This explosion proof speed dome camera uses a set of optical features to balance light throughout the scene, resulting in clear images in dark environments.


Wide Dynamic Range

CZ637 explosion proof PTZ speed dome camera achieves vivid images, even in the most intense contrast lighting conditions, using industry-leading wide dynamic range (WDR) technology. For applications with both bright and low lighting conditions that change quickly, True WDR (120 dB) optimizes both the bright and dark areas of a scene at the same time to provide usable video.



This feature controls the pan/tilt/zoom actions of the camera to automatically track an object in motion and to keep it in the scene. The tracking action can be triggered manually or automatically by defined rules. Once a rule is triggered, CZ637 explosion proof PTZ speed dome camera can zoom in and track the defined target automatically.



CZ637 explosion proof PTZ speed dome camera is certified ATEX/IECEx Hazardous Location. Zuoan can respond respond to all of these challenging demands with a wide range of equipment with the most advanced technical features for CCTV systems that operate in Marine(with high corrosive salt), offshore, Oil & Gas and industrial locations (IIB and IIC).
