Good first effort, you need a camera over-viewing the whole out-front [2.8mm lens] move the current camera down about a meter to catch the faces.
Note a cam behind a window wont work real well the IR will reflect back. You could put a pin-hole there but they are only 1mp [lets crank it up HIK !]
Oh seeing your now buying more cams Install one pointed down the road with a bit of zoom to catch plates. [say 12mm lens]
I have 8 cams out the front 3 wide angle [2.8mm HIK 4Mp domes] And a couple of hundred watts of IR -non covert, normal people dont notice but crims run.
two custom number plate capture and two for color at night. The other two are on the fence looking wide angle up the street left & right.
Im about to put a HIKvision pin-hole at the door as well to get an in the face shot -height 120cm -watch out where the sun is tho
Its a little excessive but I have caught every single thief with amazing shots of their faces and cars. -Im in a high crime rate industrial area.
If the cops dont mind [no current wide investigation] with this scum paste it on facebook as well
He looks like he bald as well dressing up like his 20
One last thing have a walk around a few blocks and see if anyone has a camera you can access, I bet scum-man has been there
