WiFi Door Alarm System, Wireless DIY Smart Home Security System, with Phone APP Alert, 8 Pieces-Kit (Alarm Siren, Door Window Sensor, Remote), Work with Alexa, for House, Apartment, by tolviviov

An excellent purchase! This door alarm exceeded all my expectations. It's affordable, easy to install, and extremely effective. Within minutes, I had it working at both the front and back entrances.The sound is loud and deterrent, ideal for alerting anyone who tries to open a door without authorization. It gives me great peace of mind knowing I have an extra layer of security without having spent a fortune.Perfect for apartments, houses, and even for traveling. For the price, I honestly didn't expect much, but it has been one of the best investments for my home security.

I'm super excited to have this in my home for extra protection! My 2 year old learned how to open doors so I needed to protect him. They were easy to install and link to an app that's easy to use and alerts me virtually if any door is opened. I'm super excited to see how we'll it works and how long it continues to work. I didn't want to hardwire a system in but that's my next step if this easy one doesn't work. I love it so far!

I wish the alarm speaker was a little louder, but everything seems to be working within the app. There is a lot of navigating within the app but that’s just user error on my part. I don’t know if I’m gonna be able to figure out how to mount all of the sensors within my RV and once again that is something I didn’t consider before purchasing the system.

I'm very happy with this system. It came with everything I needed, and I installed it in less than 30 minutes. The best part is there are no monthly fees. I get notifications on my phone if a door or window is opened. Ideal for tthose of us who want hassle-free security. "After comparing several options, I chose Tolviviov because of its price and features. I was surprised by how comprehensive it is: door and window sensors, app control, and Alexa compatibility. It works perfectly, even when I'm away from home."

This home security system by Toliviviov is much more capable then you'd have thought coming from a brand that no one has really ever heard of. Now that's not a detraction rather a compliment. I've been without a home security system for a while. I had been using Piper, a stand alone one piece home security system that you set up and is self contained. But it eventually died and the Piper company through mergers and such has seemingly gone out of business; you can't even find them listed on Amazon anymore. So I've done without until some family friends asked for my help in home security. Researching and purchasing for them was the imputes I needed to look for myself and I came to the conculusion that there are a lot of DIY systems out there running the gambit from cheap to expensive, but you're seemingly paying for the same sensors and the app each uses does largely the same thing. Surprisingly the Tolviviov is surprisingly robust and capable. It came boxed securely and quickly, the sensors were easily paired and I had the system up and running in almost no time. I've since looked into getting water/leak sensors cause you really have no excuse for inexpensive sensors to alert you to a leak or a busted hose/pipe before water damage can occur. I've quickly expanded to fourteen sensors and you can have a total of twenty as listed. The Tolviviov people were quick to respond when I asked a question.The only negative thing I have to say is that the listing that I purchased had a motion detector and a stand alone battery powered keypad. However what I actually received contained additional door/window sensors and not the motion detector or keypad. I can only assume a substitution was made(?) but I'm not really worried about it as the motion detector is only twelve dollars plus shipping should you wish to purchase it and also I can easily use the included remote and the app to control the system, the keypad was just going to be back up. But I would've wished for both of them to be included as described.The only pressing concern I do have is that the ring on the base unit is only partially illuminated... I had thought it was some kind of battery charge indicator as the base unit has a battery back up, but it is in four segments and one segment is fully lit and the other three are only partially lit. I'm not sure if something's going on or I'm not doing some part of the set up (reference pic)...But the home security system from Tolviviov is available under a few different names, but you can't seem to go wrong with purchasing it. You should think about when considering it as a purchase, what are you really buying? I mean there's nothing wrong with buying a name brand system from the likes of Nest, Ring, Eufy, ADT or Simply Safe. But the door/window sensors are largely the same, there's only so many ways to make a microchip sense a magnet and put a battery on it after all. What you're really paying for is the name on the system and what you hope is a capable app. If you don't mind buying generic, so long as it has a capable app which this does, you can secure your property and save a bundle...
