Hi @SHIRLEYn81! There are so many variables to consider that no one in their right mind would give you an answer.
I would try one first and see what happened, or even turn your mobile onto WiFi rather than sim and see what reception was like where you plan to site the camera.
WiFi extenders are quite reasonably priced if the signal from the router is inadequate.
From the 29th of March our TalkTalk Community will move to peer-to-peer support and the TalkTalk team will no longer be here to support with queries. Don't worry we still have plenty of ways to reach out if you need to speak to TalkTalk directly. For more details check out the link here:
