@ marcogovoni - I'm sorry to hear you're having troubles connecting to this camera. If you turn off all other cameras will this one connect? If so, you may be experiencing network congestion.
Are you using the default username:password of admin:<blank>? If so, please create a custom admin user for the camera and try connecting. We have a couple of users report issues connecting their Foscam cameras in Sighthound with this default username and password.
@ Jepsh - We have a small number of users report similar issues with the latest update. One user reported success after editing the camera and reconfiguring it using UPnP. If your camera supports UPnP I'd recommend trying this. Our engineers are currently hard at work on resolving this issue. In the meantime if you'd like to revert to the previous version of Sighthound you can do so at
