There are so many topics on cctv, door viewer, monitor, alarms etc.
I would appreciate a simple solution to see and record who is at my front door ( only external door to a small apartment) and when I am not around, it will record anyone snooping and also works as a door bell.

I found digital door viewer which could do all that without a door bell. Shopee carries some brand to Phillips and the price ranges from rm 98 to 1000+.

There is an all in one digital door viewer cum doorbell costing less than 200. While I like low prices, I know quality of electricals vary directly with price.

Can I have suggestions please?

I took a look at the shopee offering.
It says to stick it on the door? Sounds like some thief can remove it easily. I don't plan to install grills. Nobody pinched yours yet?

Sounds promising, thank you, will read more about it.
