I'm having two security cameras being installed today. One will go on the front of my house, and will sit close to the garage door. The other is going to be behind the house. Between both cameras is the garage. Now, the guy who came to install it said I needed at least an 80% signal strength in the tests he did, but we could only get to 60%. I have a mesh wifi system, so I tried moving one of the mesh wifi points into the garage, but still no improvement. We later found out it was due to thr garage door. When it was open, the strength between the front camera and the network was over 90% , but when the garage door was closed, it went to around 60%. Is there anything I can do to get a stronger signal in the garage? Get a wifi booster?
