Dahua 3X66 Series

Visit CTC Communications to explore the exceptional deals on cutting-edge Dahua Security Surveillance Cameras from the latest 3X66 Series, designed for optimal security monitoring needs.

Introducing the New 3X66 surveillance cameras with advanced features designed to enhance security and reduce false alarms. Equipped with Quick pick, SMD 4.0, and AI Self-Adaptive technology, these cameras deliver an impressive 99% increase in surveillance detection accuracy. Additionally, the 3X66 cameras significantly reduce false alarms triggered by small and large animals, providing reliable and efficient monitoring.

Quick Pick

Quick Pick technology can quickly identify human/vehicle targets of interest, which optimizes the search for relevant SMD events. With excellent integration of intelligent functions of both cameras and recorders, this feature can search human/vehicle targets based on AI algorithm that can extract and compare clothing and vehicle colors.


AI SSA (Scene Self-adaption) technology is based on deep learning algorithm that can intelligently identify multiple scenes and adjust to their optimal images.

AI Coding(IP Solution)

With the improvement of monitoring resolution, how to maintain image quality while saving storage cost has become one of the most concerning problems of users. Based on CBR (Constant Bit Rate), WizSense AI Coding dynamically allocate bit rate, providing clear target images while saving more than 25% bit rate compared with H.265.

SMD 4.0

With upgraded AI capabilities, the SMD function filters out irrelevant objects in the scene. Equipped with new deep learning algorithm, SMD 4.0 is optimized to filter out small and large animals in the scene to avoid triggering false alarms.
