Do they leave a residue? Could you use them in a vacation rental without leaving gluey stuff on their door?** A: If you used comand strips. The product it comes with is foamy double sided tape and will leave a residue after removing. **Q: Would this be suitable to secure my camper van windows and doors when van is parked in driveway/campsite or at hiking trail?** A: These are obviously not 'high security'. Rather, they just make a noise that is loud enough to be a good deterrent to a would-be thief. So I think these would be very suitable to help secure camper van windows and doors IF you are parking your vehicle where there are people nearby who will respond to the alarm noise. They aren't extremely loud, but they are loud enough for people within maybe 150 feet or so to hear the alarm. **Q: How long battery last?** A: It will last 40-60 minutes continuously. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great in imperfect mounting situations. *by J***W on May 3, 2020* This is a great product that is easy to install and operate.I was concerned after reading several reviews that the alarm and sensor would need to be mounted very close to each other to achieve proper operation. After a bit of hand testing I found that gaps of one-half inch would keep the alarm from going off. In one of my installations the alarm unit and sensor are no even parallel to each other with no adverse affects to performance. Would like to upload some pictures of my install, but either Amazon or the seller seem to have this disabled.The unit is easy to use with the three position micro-switch; High, Off and Low. The only comment I would have is that because it is a micro-switch people with limited dexterity might find it difficult to use.I did not evaluate battery life because, frankly, I cannot imagine listening to this thing go off on high for anything more than a few seconds. ### ⭐⭐⭐⭐⭐ Awesome door alarm! *by S***N on September 11, 2021* I love this door alarm! Its easy to install & loud. OMG 😲 it's loud! It's just what I was looking for. Mom is 88 & got out once which is 1 time too many. This alarm will scare the s**t out of you. It's awesome! ### ⭐⭐⭐⭐ Works, low is low and loud is loud *by A***R on May 11, 2020* Although these arent the most appealing with how shiny silver they are. The loud setting is actually quite loud and is what I was looking for when I am gaming or playing music. ## Frequently Bought Together - Door Window Alarm Sensors 4 Pack New Version with Two Volume Levels NOOPEL Burglar Intruder Entry Sensor Alert for Home Security with Batteries Included - LiCB 20 Pack LR44 AG13 357 303 SR44 Battery 1.5V Button Coin Cell Batteries - Door Window Alarm 2 Pack, New Version with Two Volume Levels,NOOPEL Burglar Intruder Entry Alarm for Kids Toddlers Indoor Personal Safety --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.es/products/164328465-door-alarms-when-opened-4-pack-new-version-with-two](https://www.desertcart.es/products/164328465-door-alarms-when-opened-4-pack-new-version-with-two) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-06-07*
