Cohu Nexus PTZ High-Definition IP PTZ Camera System for Critical Infrastructure Perimeter Surveillance with AI Video Analytics

The Cohu Nexus PTZ is the industrial-grade PTZ dome surveillance camera designed for the outer perimeter of critical infrastructure installations — power plants, high-voltage electrical substations, water treatment facilities, military bases, and ports — that operate in extreme climatic conditions without permanent surveillance personnel at each point and need automatic intrusion detection with threat type classification before the operator reviews the image.

The 1/1.8" image sensor with 4K/30fps resolution and 30x optical zoom (960x total zoom with 32x digital zoom) enable identifying a vehicle license plate at 150 meters or a person's face at 80 meters from a single installation point — covering typical substation perimeter radii without multiple narrow-field cameras. The NexusAI embedded AI video analytics module automatically classifies people, wheeled vehicles, and tracked vehicles in the image with a false positive rate below 0.8% in rain, fog, and snow conditions, and generates categorized intrusion alerts directly in the VMS without an external analytics server.

The high-pressure automatic lens wash system integrated in the dome maintains optical clarity at coastal installations with salt accumulation, dust-emitting processing plants, and high-humidity environments with frequent condensation — without requiring manual maintenance between cleaning cycles of up to 72 hours. Operation at -50°C uses the sensor's automatic start-up heater to guarantee full image timing from startup in Arctic or Andean high-mountain environments, while passive thermal dissipation manages the +60°C of coastal desert installations.
