The Dahua NVR4116-4KS3 is a 16-channel, premium-quality 1U network video recorder designed for robust surveillance systems. Powered by a reliable industrial-grade processor and embedded Linux, it supports IP cameras with up to 12 MP resolution. The NVR delivers smooth playback with its decoding capability for up to 16 × 1080p streams at 30 fps. It features advanced video compression options including Smart H.265+, H.265, Smart H.264+, and H.264, significantly reducing storage needs and network load without compromising image quality. With a bandwidth capacity of 160 Mbps for incoming, recording, and 64 Mbps for outgoing streams, it delivers efficient and uninterrupted recording, even during high-demand scenarios. The device includes one SATA interface supporting a hard drive up to 20 TB capacity, allowing for long-term video storage. The HDD is not included in the package and must be purchased separately, giving users the flexibility to choose the most suitable drive for their needs. This device offers a solid balance of high-resolution video, efficient compression, and scalable storage for modern surveillance environments.

Integrated with Dahua’s WizSense technology, the NVR4116-4KS3 provides enhanced intelligence that improves accuracy and efficiency in surveillance. The recorder supports 4-channel SMD Plus, which accurately filters human and vehicle targets from irrelevant objects such as leaves, light, or animals, minimizing false alarms. When paired with compatible Dahua AI cameras, the NVR also enables advanced functions including face detection, perimeter protection with line crossing and intrusion rules, people counting for retail analytics, stereo analysis for behavioral studies, and heat mapping to track density in monitored areas across up to 12 channels. These functions are provided by the connected cameras, since this recorder does not process AI analytics on its own. For playback, users benefit from multiple modes such as instant, event-based, tag-based, or smart search, making it simple to locate critical video segments. Multi-channel playback of up to 16 channels runs smoothly, while features like electronic PTZ, one-click arming/disarming, and support for ONVIF integration provide flexibility in diverse setups.

Two USB 2.0 ports provide easy access for data backup and mouse control, while one RJ-45 10/100/1000 Mbps Ethernet interface ensures stable network integration. The recorder offers multiple storage options, including FTP, SFTP, NAS, and DAS, allowing users to archive video footage efficiently. These options ensure compatibility with direct-attached drives, network servers, and remote storage systems, giving flexible choices for data management and backup strategies in diverse surveillance setups. Its security features include IP/MAC address filtering, HTTPS encryption, trusted certificates, and dual-user accounts, safeguarding both data and access. Compact and energy-efficient, this NVR is designed for reliable, long-term performance in professional security systems.
