These are perfect if you have children or elderly people who elope. These are easy to install, extremely loud for alerts, and very simple directions to program the remote.

La alarma funciona bastante bien, tiene un sonido fuerte, lo unico que no me agradó mucho es que la alarma deja de sonar si vuelves a cerrar la puerta o ventana. Una de las alarmas venia con parches de pegamento viejo (tuve que retirarlos con calor y ponerle nuevos) pero en general cumplen con la función de "alarmar" y que se percibia la alarma en toda la casa.

I tried out a few different options for a DIY home alarm system and these were the ones that absolutely fit the bill. I started out with a pair of them to test out and ended up buying 3 more sets. Why?1) Extremely easy to set up. There is a little give in the space needed between the magnets and the actual alarm, so if your windows/ doors and frames aren't flush, no problem 2) Range! I can arm and disarm the units in my basement from my second floor. I was very surprised and happy about this! 3) Compatibility of components- I had to watch a Youtube video to learn how to do this, but it turns out, you can pair every single transmitter to work with ALL the alarms, and ALL transmitters can be paired to activate every single alarm. 4) Abundance of key fob transmitters. Every alarm comes with a transmitter so everyone in the family can have one that works the same as the next 5) Panic button: because I can activate the alarms from such a long distance, I use one of the transmitters as a panic button in my bedroom. If I hit the "lightning bolt" button, I can get ALL the alarms in the entire house to go off together. If that doesn't scare the $%#t out of an intruder, then nothing will. 6) Doorbell function: you can set the alarms to give off a double ring, just to alert you when someone opens a door or window. It's pretty loud, but would be good if you're outside or in the basement and want an alert of this kind. 7) Cost: I paid a lot more more for a lot less when I first started testing out different components for my home security. I returned the others after I saw what this system could do. 8) Power: I like that they run on batteries, so if power gets cut, they will still work.Cons? No internet alerts when your system gets set off. This is a real time, intruder focused system, not a monitoring system (so no monthly fees- another pro). To address this, I also bought a couple of Reolink security cameras to provide eyes into my home. They alert me if motion is detected inside the house. Because it has 2-way audio, I should be hearing a hell of a racket if someone actually gets in. Anyway, I am very happy with the synergy between these two systems.

PROS: Easy installation. I installed two alarms on both my doors in about 5 mins. The box included a remote, the host (big white box that goes on door), magnet box (slinder white strip), and 3 adhesive strips.Remote is already programmed to the alarm, so no need to do that. Adhesive strips seem to hold well. Alarm is loud...very loud. Remote is also very sleek looking and resembles the keyless remote to my car. And yes, you can put it on your keychain.CONS: Although I appreciate the loudness when the alarm is in armed mode, it is WAY too loud for just the normal doorbell function which alerts you the door is being opened. I don’t even use this function for that reason.If you have more than one alarm (as I do) you have the ability of pairing one remote to multiple alarms. However, the downfall of this is that whatever mode you put the paired remote on, this mode will apply to any alarms paired to that remote.Just because I want to arm my front door at night doesn’t mean I want to arm the door of my child’s bedroom as well. I just want to be alerted that he is trying to get out of his room (via doorbell mode). After finding this out I had to unpair the remote and repair them with their own individual alarm.Despite the cons, I find the pros outweigh the cons. It’s well priced and seems to be of good quality. Granted I’ve only had it for one day, but so far so good.
