Door phone, camera or alarm: what to buy first for a flat

For flat owners on a budget, one device is often enough to start. How the three compare and which suits which home.

Customers in apartments often call us wanting “some security” but with a limited budget, around ₹10,000 to ₹15,000. In most flats, one well-chosen device is enough to start. Here is how the three options compare.

A video door phone shows who is at the door on a 7-inch screen inside, lets you speak to them, and records a photo of every visitor. It costs about ₹9,000 to ₹13,000 installed. It suits elderly parents living alone, homes with frequent deliveries, and anyone who is uneasy opening the door to strangers. Calls can also ring on your phone when you are out.

A single camera outside the door, recording to a memory card or small recorder, costs about ₹6,000 to ₹9,000. It suits flats where the main concern is what happens in the corridor when you are away, such as parcels or visits by staff. Please check your society’s rules first, as some associations restrict cameras in common areas. A wireless alarm with door sensors and a motion detector costs ₹12,000 to ₹18,000. It suits homes that are often left empty, as it alerts your phone and sounds a siren if a door opens when the system is armed.

For most families, we suggest the video door phone first. It is used every day, not just when something goes wrong, and it can be joined later by a camera or alarm on the same app.
