The Hikvision 32 Channel AcuSense DVR iDS-7332HQHI-M4/S (5MP/4K+32CH+AI Motion Detection+Perimeter Protection+POS+H.265 Pro+) is a high-capacity, AI-enhanced digital video recorder built for large-scale surveillance systems.
Equipped with deep learning algorithms, it delivers:
-
Perimeter protection for line crossing, intrusion, and region-based detection.
-
AI-powered motion detection 2.0 on all analog channels, with human/vehicle classification to reduce false alarms.
It supports 32 analog channels with encoding up to 1080p @ 15 fps, while allowing up to 48 IP cameras (up to 5MP/4K resolution) for hybrid flexibility.
The DVR includes POS integration, enabling transaction data overlay and triggered recording — ideal for retail, banking, and commercial surveillance.
With H.265 Pro+/H.265 Pro/H.265/H.264+/H.264 compression, it minimizes storage and bandwidth costs without compromising video quality. It also features 4 SATA interfaces for large-scale storage expansion.
