The ARN-7516P-4K is a high-performance 16-channel 8MP/4K Network Video Recorder (NVR) with integrated Power over Ethernet (PoE) functionality. Equipped with 16 built-in PoE ports, it delivers power supply and video transmission through a single network cable with a maximum distance of up to 100 meters, eliminating the need for extra power wiring. Powered by an industrial-grade embedded HiSilicon CPU and running an embedded Linux OS, it features an advanced H.265 High Profile compression algorithm that reduces stream bandwidth by 30% via space-time filtering technology. Designed for high-definition surveillance environments, it offers seamless 4K video recording, multi-channel synchronous playback, and intuitive control, making it an ideal choice for commercial facilities, campuses, residential complexes, and enterprise security setups.

• Supports up to 16-channel 8MP/4K IP camera inputs.
