A camera isn’t going to stop a determined thief and yes they will undoubtedly have their faces covered but I would still strongly recommend getting one as sometimes what it captures can prove to be invaluable as I’ve recently discovered.
The ‘Ring wireless floodlight cam’ would be a good choice. I won’t go into too much detail as you will find everything you need to know online, but what I will say it that it’s fantastic all round, the infra-red night vision is the best I’ve seen, has a great app which runs fast and the unit is very simple to install and even easier to setup. They typically retail for around £250 but when on offer can be had as cheap as £149, worth every penny at even full retail. All recordings are automatically uploaded to the cloud with 30 days history and Ring have the cheapest cloud plan for unlimited recording at only £25 a year. Compare that with some of their competition, ‘Nest’ £240 a year and ‘Hive’ a crazy £360 a year! You also get free theft protection for as long as you own the camera, if after installation the camera got stolen by someone ripping it off (not easy done), Ring will send you out a replacement for free!
You can do the same with the FL A3/RS. I deactivate the keyless entry every night, much better than using a faraday pouch.
