Frequently Asked Questions

Why does my Synology camera keep disconnecting randomly?
Random disconnections are usually caused by network instability, insufficient bandwidth, or power issues. Check your network switch capacity, ensure adequate PoE power delivery, and verify your internet connection is stable.
How do I find my camera's RTSP URL for Synology Surveillance Station?
The RTSP URL varies by camera brand. Common formats are rtsp://[IP]:554/live/ch00_0 or rtsp://[IP]/stream1. Check your camera's manual, web interface, or contact the manufacturer for the exact RTSP path.
Can too many cameras cause connection drops in Surveillance Station?
Yes, exceeding your network bandwidth or NAS processing capacity can cause cameras to drop. Monitor your network utilization and consider reducing video quality, frame rates, or upgrading your network infrastructure.
What should I do if Surveillance Station says 'camera lost' after a power outage?
After power outages, cameras may receive different IP addresses from DHCP. Check your router's connected devices, update the camera's IP address in Surveillance Station, or configure static IP addresses for your cameras.
Why can I see my camera in a web browser but not in Surveillance Station?
This indicates the camera's web interface works but the RTSP stream has issues. Verify the RTSP port (usually 554) isn't blocked, check the RTSP URL format, and ensure the camera's streaming settings allow multiple connections.
