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.
