Outdoor camera: How to prepare sensibly?

The users and others have already given you some quite valuable tips (reflection etc.). I had the cameras connected via network cables with PowerOverEthernet (POE) in the last house as well as now in the new house. Works perfectly. However, there are also some models that have their own power supply (then you would have to leave space for a transformer). But many models work with POE. Regarding placement: high enough to protect the camera from vandalism, but low enough so you can still see faces (and not the bald heads/hats of people). I would choose a pan/tilt dome CAM (the one with the round half-glass). No spider can spin its web in front of that, I had that problem with the old cameras with classic housing. Apparently the devices emit a bit of heat or for some other reason the critters find these housings so attractive. The half-round DOME CAM is easy to maintain and a small flush-mounted box is sufficient. Others have already said something about reflection, shadow casting etc. And as mentioned above, definitely do not integrate via WLAN. The cameras transmit images and videos and LAN cables have up to four times the data throughput compared to WLAN. WLAN performance is usually insufficient for such applications (except for a single toy cam from the hardware store). And if you also want to record at night, either provide power cables for infrared illuminators near the camera or invest in corresponding camera technology. Possibly a motion detector near the cam also makes sense, which then switches on the outdoor lighting so the cam can see something.
