Dahua Technology Pro Series 52C232XANR 2MP In-Ceiling PTZ Network Dome Camera

The 52C232XANR 2 MP Starlight PTZ Dome camera features a 1/2.8-in. STARVIS™ CMOS imager with a 30x optical zoom lens, and provides an all-in-one solution for capturing long-distance video surveillance for indoor applications.

The 52C232XANR camera uses the Smart H.265+ video compression standard to improve encoding efficiency while preserving high-quality video.

The 52C232XANR PTZ camera is equipped with quick and accurate pan/tilt/zoom control and True WDR for applications with direct sunlight or glare.

Starlight Technology

For challenging low-light applications, Dahua’s Starlight Ultra-low Light Technology offers light sensitivity that captures details in low light down to 0.005 lux.

The 52C232XANR camera uses a set of optical features to balance light throughout the scene, resulting in clear images in dark environments.

Wide Dynamic Range

The 52C232XANR 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.

Intelligent Video System

IVS is a built-in video analytic algorithm that delivers intelligent functions to monitor a scene for Tripwire violations, intrusion detection, and abandoned or missing objects.

A camera with IVS quickly and accurately responds to monitoring events in a specific area. In addition to scene analytics, the 52C232XANR camera offers tamper detection by recognizing a dramatic scene change and generating a warning message to inspect the camera.


This feature controls the pan/tilt/zoom actions of the 52C232XANR 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, the 52C232XANR camera can zoom in and track the defined target automatically.

PFA Technology

The 52C232XANR 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.

Smart H.265+

Smart H.265+ is the optimized implementation of the H.265 codec that uses a scene-adaptive encoding strategy, dynamic GOP, dynamic ROI, flexible multi-frame reference structure and intelligent noise reduction to deliver high-quality video without straining the network.

The smart H.265+ technology reduces bit rate and storage requirements by up to 70% when compared to standard H.265 video compression.


Dahua 52C232XANR network cameras are equipped with a series of key cybersecurity technologies including: security authentication and authorization, access control, trusted protection, encrypted transmission, and encrypted storage.

These technologies improve the 52C232XANR camera’s ability to prevent malicious access and to protect data.


With a temperature range of –30° C to +60° C (–22° F to 140° F), the camera is designed for extreme temperature environments.

The 52C232XANR 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.).
