With the new CC400W I purchased a couple and installed at my mom’s house, she lives alone. I wanted to add these remote cameras to my home NAS Surveillance Station for monitoring and recording. The cameras are set up at my mom’s on her Wi-Fi network, I gave them a fixed internal IP address, I used external port 8881 and 8882 to the respective cameras fix IP address using internal port 443. I can go on a web browser from my home, enter my mom’s publicly addressable IP address and the respective port 8881 or 8882, enter the username and password to the CC400W and I get the Synology Camer interface and video stream. When I go to Add camera within Surveillance station on my DS1522+, I add manually, I enter my mom’s IP address, HTTPS port 8881 or 8882, I select Next, I then Authenticate, enter the Username and Password of the respective CC400W, leave the port as HTTPS and 8881 0r 8882, hit Authenticate, I get a thumbnail of the camera and a Green Checkmark under Status. When I hit Next, I use Quick Set Up, review the Summary and hit Done. Surveillance Station then goes through an Activating cycle which results in “Disconnected.” Is there additional settings or configurations I am missing? Thank you.
I was able to solve the issue. There is an Advanced tab under the Edit Camera option, it has a Port Forwarding section which gives you the ability to configure a customized port number to connect to the camera in addition the port 443, I had also created a port forward from external port 9555 to internal port 554 to the fix IP address of the CC400W camera. I checked the “Customized RTSP Port” box and entered the 9555 and then Save. Surveillance Station then reauthorized and it worked. It needed to have both the port 443 HTTPS web UI and the port 554 RTSP, which the Edit Camera, Advanced Tab let you add, so both were in play. I could have missed it, but these added instruction for a remote Synology camera functionality were not anywhere that I could find. Another self-asked/answered post on the forum.
Great question—this is a classic scenario when adding remote cameras behind NAT to Synology Surveillance Station.
Let’s break this down carefully, because you’ve done almost everything right:
Your configuration so far:
-
Remote site: Cameras on local fixed IPs (e.g., 192.168.1.X), HTTPS port 443.
-
Remote router: Port forwards:
- PublicIP:8881 → Camera1:443
- PublicIP:8882 → Camera2:443
-
From a browser: You can access camera streams over HTTPS externally.
-
Surveillance Station: During Add Camera, authentication succeeds and you see thumbnails.
-
But after hitting Done, Surveillance Station tries to activate recording—and fails with “Disconnected.”
This usually means:
-
The test connection (authentication) uses HTTPS for login and thumbnail, which works fine.
-
The actual video stream protocol (RTSP) fails, because:
- RTSP uses additional ports.
- Synology tries to access RTSP port 554 by default.
- Your port forwarding rules only forward 443 (HTTPS), not RTSP.
Why does this happen?
Many IP cameras have:
- A web admin interface over HTTPS (port 443).
- A video stream over RTSP (port 554 or another dedicated port).
- Surveillance Station uses RTSP to record video.
When you set up the camera in Surveillance Station:
Login and snapshot: over HTTPS (your ports 8881/8882).
Video stream: RTSP (probably not forwarded).
That’s why you see the green check at login but end up disconnected.
How to fix it
Identify the RTSP Port on your CC400W
Usually:
-
Default RTSP port: 554
-
Sometimes cameras can use alternate ports. Check:
- The camera’s web interface under Network or Streaming settings.
- The manual.
- Any reference to RTSP or Media stream ports.
Add Port Forwarding for RTSP
On your mom’s router:
-
Add a rule:
- Public port: e.g., 8554 (for camera1), 8555 (for camera2)
- Internal IP: camera’s fixed IP
- Internal port: 554 (or whatever RTSP port you found)
Example:
| Camera | Public Port | Internal IP | Internal Port |
|---|---|---|---|
| Cam1 | 8554 | 192.168.1.10 | 554 |
| Cam2 | 8555 | 192.168.1.11 | 554 |
Configure Surveillance Station to use the correct RTSP port
When adding the camera:
-
Under Advanced Settings (instead of Quick Setup), set:
- RTSP Port: 8554 (or whichever you mapped)
- HTTPS Port: 8881
-
Make sure the Video Path is correct (sometimes
/Streaming/Channels/101or similar).- Surveillance Station often autodetects this.
- If not, refer to your camera documentation.
Verify Firewall Settings
If the camera or router has a firewall:
- Allow inbound RTSP connections.
- Allow HTTPS management connections.
Test the RTSP Stream Independently
Before adding to Surveillance Station, test the RTSP URL with VLC:
VLC test URL format:
rtsp://username:password@publicIP:8554/Streaming/Channels/101
Replace:
username/passwordpublicIP8554- the correct video path
If VLC plays the stream, Surveillance Station will too.
Try Adding Again
After forwarding RTSP and confirming VLC access:
-
In Surveillance Station:
- Add manually.
- HTTPS port = 8881/8882.
- RTSP port = 8554/8555.
- Do a connection test.
- Finish setup.
Quick Checklist Recap
Port forward HTTPS (done).
Port forward RTSP (needed).
Confirm firewall allows RTSP.
Test RTSP in VLC.
Input the correct RTSP port & path in Surveillance Station.
If you share:
- The camera’s model-specific RTSP path, or
- A screenshot of your Surveillance Station Advanced Settings page,
