Costar Waterproof Wireless Doorbell — 1000 ft Range, 32 Chimes

<p>The doorbell you cannot hear from the kitchen, the terrace or the back bedroom is a daily annoyance in most Indian homes — and rewiring a new one means chasing an electrician. This Costar set is fully wireless: a waterproof push button sticks to the gate or door frame, and the receiver simply plugs into any socket, so you can move it (or add a second one) as needed.</p><p>It is overlooked because people search for smart video doorbells costing ₹5,000+, when the actual problem is just range and volume. The 1000 ft range covers independent houses and terraces, with 32 chimes and 5 volume levels plus an LED flash for noisy rooms.</p><p>Rated 4.2 out of 5 from 540+ Flipkart ratings, with buyers highlighting the loudness and that the button survives rain.</p>
