System Overview
The 4MP IR PTZ Dome camera uses a 1/2.8-in STARVIS™ CMOS imager with a 45x optical zoom lens, providing an all in one solution for capturing long-distance video surveillance for outdoor applications. The camera offers Analytics+ functions at the edge - performing complex perimeter protection surveillance with Smart Motion Detection to distinguish human and vehicle motion, significantly improving accuracy and reliability as compared to standard intelligent features.
Functions
Perimeter Protection
Dahua Analytics+ includes Tripwire and Intrusion functions that offer custom tripwires based on object type for automation in limited access areas. Perimeter Protection requires less pixels to detect an object to deliver improved accuracy and decreased false alarms due to lights, weather, trees, or animals.
Alarm Track
Controls the pan/tilt/zoom actions of the camera to automatically track a human or a vehicle that triggers an alarm based on a Perimeter Protection rule. Once an alarm is triggered, the camera tracks the target automatically until the target leaves the scene or the tracking time is exceeded.
Smart Motion Detection
Smart Motion Detection, a component of Dahua's Analytics+ technology, improves alarm accuracy and decreases the number of false alarms. The advanced SMD algorithm analyzes a scene for human or vehicle motion, while filtering out other motion due to trees, leaves, animals, weather, and triggers an alarm when detected. SMD also saves time when searching recorded video by filtering false alarms and allowing quick retrieval of an alarm due to a person or vehicle.
Predictive Focus Algorithm+ Technology
The camera uses innovative PFA+ Technology to improve zoom accuracy and to decrease focus time. A series of advanced algorithms more accurately judge the direction and the distance to a subject, improving picture clarity throughout the zooming process and decreasing focus time. PFA+ extends lens life by 10%.
ArcticPro
The Dahua ArcticPro Series of extreme-environment cameras combine temperature-tolerant components, a waterproof enclosure, and an integrated heater to ensure flawless operation in temperatures as low as -40° C (-40° F). For applications that demand high-resolution video with advanced features in extremely cold environments, the Dahua ArcticPro Series offers a camera to satisfy the most demanding requirements.
Environmental
The camera complies with the IK10 Vandal Resistance impact rating making it capable of withstanding the equivalent of 5 kg (11.02 lbs) of force dropped from a height of 40 cm (15.75 in.). Subjected to rigorous dust and water immersion tests the camera suitable for the most demanding outdoor applications. The camera carries an IP67 rating that ensures protection from total dust ingress and protection from water immersion between 15 centimeters and 1 meter in depth.
Protection
The camera allows for ±25% input voltage tolerance, suitable for the most unstable conditions for outdoor applications. Its 6KV lightning rating provides effective protection for both the camera and its structure against lightning.
