If you want to see who's at the door without opening it—and without drilling a ton of holes for a traditional doorbell camera—this EZVIZ CP4 peephole camera is a great alternative.

It replaces your existing peephole with a 1080P HD camera on the outside and a 4.3-inch color touch screen on the inside.

The wide 166-degree lens gives you a full view of whoever's out there, day or night, with infrared night vision that works even in total darkness.

The 4600mAh rechargeable battery lasts up to 3 months on standby, so you're not constantly charging it.

It detects human motion with customizable sensitivity, so you get alerts without false alarms from cars or pets.

Two-way talk lets you chat with visitors even when you're not home, and there's even a voice changer if you'd rather sound anonymous.

You can use free cloud storage (6-second loop) or pop in a microSD card up to 256GB for local recording.

Installation requires an existing peephole hole (16.5–50mm diameter) and door thickness between 35–105mm.

If you don't have a peephole, you'll need to drill one.

It works with 2.4GHz Wi-Fi and supports Alexa/Google.
