Review: We used this to monitor a ground-floor window where our A/C was installed. It never went off in error, but did work when the sensor was tripped. So, it works! I'm not sure I trust the ISM 415Mhz open RF, though - the unit could easily be jammed or triggered from an RF relay attack. So, use it accordingly. It does what's advertised. Review: Buen producto y facil uso. ## Features - Door alarm uses remote control to set security code for arming/disarming.

The alarm will be set up outdoor on a tree and need a 50-60 foot power cord extension.** A: I have had 3 of these in service for about a year, they all work fine after initial setup. I have had 2 "false alarms" during that time. One at 2 AM...there was no entry after I checked, but on the way out, I did find that the door sensor had lost adhesion to the metal door, fell off, and that caused the alarm. After attaching it back more permanently, not problem. The other "false alarm" (again, no entry) I found that one motion sensor was not blinking red.....dead 9V battery. A quick battery replacement, and the alarm was armed again. One horn is in the out building, the other horn is in the house. Both horns went off when triggered. Tough to find a better system for the money, and the customer service has been great so far. (All my horns/sensors are inside, can't speak to exterior use, but the horn looks durable enough.) **Q: Does this system really require 220 volts to operate as stated ?** A: 220 is never needed for anything but maybe a stove, dishwasher hookups. Generally a good size welder requires 220v. These have to be simply household plug-in capable and it should probably say that a little more clearer. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by C***R on 12 November 2025* We used this to monitor a ground-floor window where our A/C was installed.

One of the standout features is how incredibly loud the alarm is, it definitely grabs attention right away and makes me feel much more secure knowing it can deter any potential intruders. The system works great both indoors and outdoors, and setup was surprisingly simple. Everything feels reliable and well-made, and I like how responsive the sensors are. Overall, this is a solid security system that delivers peace of mind. If you’re looking for something effective with a loud, attention-grabbing alarm, I would definitely recommend the KERUI Home Security System. ## Frequently Bought Together - KERUI Home Security System Indoor Outdoor Weather-Proof Siren Window Door Sensors Motion Sensor Alarm with Remote Control More DIY, Wireless House Hotel Garage Shop Burglar Door Alarm, NO WIFI/GSM/APP - KERUI Standalone Home Office Shop Security Alarm System Kit,Wireless Loud Indoor/Outdoor Weatherproof Siren Horn with Remote Control and Door Contact Sensor,Motion Sensor,Up to 115db,NO WiFi/GSM/APP - KERUI 433MHz Home Wireless PIR Infrared Motion Sensor Detector for Alarm System --- ## 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.gr/products/258538431-home-security-system-indoor-outdoor-weather-proof-siren](https://www.desertcart.gr/products/258538431-home-security-system-indoor-outdoor-weather-proof-siren) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-07-13*
