Description
The Dahua NVR4108HS-4KS3 is an 8-channel, premium-quality 1U network video recorder designed for robust surveillance systems in small and medium-sized IP video deployments, including homes and small businesses.
Powered by a reliable industrial-grade processor and embedded Linux, the Dahua NVR4108HS-4KS3 supports IP cameras with up to 12 MP resolution, delivering smooth playback with decoding capability for up to 8 × 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 80 Mbps for incoming and recording streams and 60 Mbps for outgoing streams, it delivers efficient, uninterrupted recording even during high-demand scenarios.
The device includes one SATA interface supporting a hard drive up to 10 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.
Integrated with Dahua’s WizSense technology, the Dahua NVR4108HS-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.
Compared to the standard 4KS3 model, this HS version 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 6 channels when paired with compatible AI cameras.
Video output is straightforward, with simultaneous HDMI (4K) and VGA (1080P) outputs available for local display, giving installers flexibility depending on existing monitors and display infrastructure at a given site.
This NVR is both cost-effective and easy-to-install, making it ideal for a wide range of applications such as cities, transportation, education, and finance, with support for EPTZ and one-click arming and disarming for straightforward system control.
Network protocol support is comprehensive, including HTTP, HTTPS, TCP/IP, IPv4, UDP, NTP, DHCP, DNS, SMTP, UPnP, DDNS, and P2P, along with 2 USB 2.0 ports for backup and device control, giving administrators broad flexibility for remote access and management.
With its compact 1U design, WizSense AI capabilities, and cost-effective feature set, the Dahua NVR4108HS-4KS3 offers a dependable entry point into intelligent IP video surveillance for growing businesses and residential properties alike.
