What model of Jidetech camera do you have? Assuming that it clams to support RTSP, it sounds like it uses a less-common RTSP url so your Camect device can't guess it automatically, and that it doesn't support Onvif or it would have been able to tell Camect what the correct url is.
The high-level overview for what to do if your cameras don't come up is
here.
In your specific case, you'll need to figure out the RTSP url that applies to your camera model -- you may be able to find it by Google search, on a page like
this one, or by asking in the manufacturer's support forum. Once you know the RTSP url, of your camera, you can add the camera manually ...
home settings (cog wheel at top) > devices > add camera ... set the type to "Stream URL" and enter the RTSP url.
You can also use the VLC app (available from
videolan.org) to fetch video from an RTSP url ... This may be a quicker way of testing than plugging things into Camect. If you get an RTSP url that works with VLC it should also work in Camect.
