Surveillance Center Device Pack 6.0.3, which support Reolink E1 Ourdoor, was withdrawn.
No ETA for a new one. 

Problem is solved.
.26 was tied to the wrong device within Synology. (leftover from dual lan connection)
Changed the IP and the Reolink configured nicely.
not just with ONVIF but also with correct Brand and Model.
thanks for all the help.
I’m glad I can keep the camera.
regards Franz

The reworked Device pack didn’t help.
Pinhole reset didn’t work.
Synology Support suggested to try a Lan Connection and that worked just fine - even discovered the camera automatically.

Finally used nmap to find out, that NVIF port 8000 was open when LAN connected:

doesn’t work for me. Tried all ports that are configured including http 80

@joseph-chircop_497308027822318
is there some kind of firewall in Reolink cameras?
At this time I cannot login using safari, as I’m getting:
Operation failed due to unknown reason.
Same iPad using chrome still works.

@joseph-chircop_497308027822318
as I said, ONVIF is enabled.
i also tried the RTSP URL. Still no connection.

@joseph-chircop_497308027822318
i’m very well aware of that suggestion. See 2nd bullet above.
didn’t help.

I got a Synology DS918 with DSM 7.1.1-42962 Update 3 and Surveillance Station 9.0.2-10061 with Device Pack 6.0.3-4471.
An existing WansView (ONVIF) Camera is working just fine.
But trying to add a new Reolink E1 Outdoor, is not possible. Trying to Authenticate fails.
Cam can be accessed with iOS App, Browser, Windows App w/o any problem.
I tried:

• With Realink and Camera Model
• With ONVIF using port 8000 (activated in Camera)
• Several different users with long and short passwords.
• moved cam to Wlan of the Fritz!Box where Synology is connected so they are in the same network.
• Same IP Adress works in Browser using https
• Tried Surveillance Center in Browser and with Windows App.
• Turned uPnP off and on in Router and E1.

Clicking on Authenticate always states that Camera is not connected.



Any ideas highly appreciated.
