Review: Very Loud Alarm, Easy Install, Works Great - Due to health issue I needed to leave my front door unlocked but wanted an alarm if someone opened the door. I put this on front storm door. A friend who's habit is to just walk in, not ring door bell, came over and when this thing went off I could hear it in the back of the house. Scared her, she stood on the porch screaming as it was loud and if she had shut the door it would have stopped..... Served the purpose. I looked at a lot of these type alarms but found this one was easiest to install as I did. The smaller magnetic piece with this device could stick to the door yet still be close enough to the door jam to work the alarm. There are many settings which was also helpful because I set it to stop once the door was closed again. Review: Easy setup - Purchased to use when staying at Airbnb so I know if someone is coming inside. Easy to set up. The alarm is somewhat loud, but could be louder. ## Technical Specifications | Specification | Value | |---------------|-------| | Battery description | Alkaline | | Brand | SanJie | | Colour | White | | Compatible devices | Home Security System | | Number of batteries | 2 AAA batteries required.

Easy to set up. The alarm is somewhat loud, but could be louder. ### ⭐⭐⭐⭐ deafening *by A***C on 4 January 2024* This product is great for its purpose but it is deafening even at the lowest volume. I wish it had a tune, or a different chime option. It does the trick so definitely don't get me wrong it's a great product but my god, if I got it for a dementia patient, sure, I'll know when they leave but I might've just gave them a heart attack in the process. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/662939404-sanjie-door-alarms-for-kids-safety-home-security-dementia-pool](https://www.desertcart.hr/products/662939404-sanjie-door-alarms-for-kids-safety-home-security-dementia-pool) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-09-20*
