Fitting a video doorbell is an excellent way to boost your home security, but if you rent your home or live in an apartment, they're just not possible. That's where the catchily-named EZVIZ EP4 Wire-Free Peephole Door Viewer comes in. This little 4K camera fits in your front door's spyhole, and provides you with all the best features of a video doorbell without any drilling or damage.
Installing the EP4 is incredibly easy, and I managed to complete the whole process in around 10 minutes thanks to EZVIZ's handy video guide (the video shows an earlier model, the CP4, but the process is identical). The most time-consuming part was waiting for the EZVIZ app to download on my phone.
