Technical Highlights
The XRN-420S supports ONVIF and SUNAPI protocols, enabling seamless integration with third-party VMS platforms via CGI support. Its 50W PoE budget efficiently powers compatible network cameras while minimizing installation complexity. The unit features 4-channel audio input/output with G.711, G.726, and AAC compression, plus 2-way audio communication for interactive surveillance scenarios.
Recording flexibility includes 4-point and 8-point polygon motion detection, quality presets, GOP and bitrate configuration, plus advanced camera controls such as WDR, Day/Night mode, shutter adjustment, and digital stabilization. Local storage is managed through a comprehensive logging system capturing up to 100,000 system and event entries each. Network protocols include IPv4/IPv6, TCP/IP, UDP/IP, RTSP, NTP, HTTP, DHCP, SMTP, DNS, DDNS, uPnP, and HTTPS.
Applications
Ideal for retail stores, office buildings, educational facilities, and small-to-medium commercial spaces requiring reliable video surveillance without extensive infrastructure investment. The compact form factor and integrated PoE+ connectivity eliminate the need for separate power distribution, reducing installation costs and complexity.

The XRN-420S balances affordability with professional capabilities. Its H.265 codec support and 50 Mbps recording bandwidth optimize storage efficiency, critical for cost-conscious deployments. The dual display outputs cater to both control room and mobile monitoring scenarios.
N+1 redundancy and ARB failover provide business continuity for security-sensitive applications. Integration with Wisenet AI cameras enables advanced analytics via CMS, future-proofing smaller installations. While limited to 4 channels and single SATA storage, the XRN-420S delivers proportionate functionality for its compact footprint—a solid entry point for organizations graduating from DVR-based systems to network video recording.
