This is a very nice DIY alarm system that is easy to set up and has lots of useful features and has no monthly fees. I got this alarm system to secure a small apartment. I was quite surprised with how well it performs and all the features it has. It is not hard to install or set up but there is no install manual provided with much information on how to do that. I got some good information from watching the videos that are provided in the product description. After some initial problem solving and getting things figured out things were very easy. I already had the Tuya app and was familiar with it as I have other home security and automation devices using it. In order to help other people getting this system set up the Default User code is: 1234 and the Default Admin code is: 6666. You can change these in system settings. This is a very nice alarm system. It has succeeded in my expectations in almost everything it does and can do. For the price this is a perfect little budget alarm system that anybody could install if they have the patience and a bit of time learning how it all works. Once set up it mostly runs itself. The two included remotes, RFID tags, motion sensor, siren, PIR motion detector, and the door/window sensor all came pre-paired. The system runs off Wi-Fi. Push notifications are instant. You can have multiple users in different locations without any issues that are able to monitor events and alarms. The screen has a beautiful, clear and easy to see display. It's a nice colorful display and the touchscreen works great. I had no trouble arming and disarming the system with the included remote, keypad, or the two included RFID tags. The door/window sensor has a small slide switch on the back that is hard to turn on without a tool and even worse was the switch to turn on the motion detector. I wish they included a tool to use to turn these sensors on and off. To change the batteries in the PIR motion detector is the same process as in a PGST PIR motion sensor. It's a great value for money if you want a straightforward, self-installed alarm with touchscreen control and optional GSM backup. It's great for the DIYer and on a budget. I've never seen an alarm system with all these features and how well it works for the same price point. I recommend this alarm system to anybody on a budget but still wants quality and features.

Was very straight forward to setup. The Motion Sensor and Siren were the main motivating factors. I already have a large amount of cameras and just wanted to add a sensor and key fobs. The ability for it to work with Alexa straight out of the box is a plus. The fact that its free and you don't have to upgrade to subscription is a plus. There is a subscription option, but its not necessary for everyone. Units are well made and durable. They don't look or feel cheap which for the price they could have. The RFID tags are usually found in higher price point systems and make the entire disarming process easy!

I was struck by how small this new home security system is compared to my current one. It's only 75% of its size and about the size of my smartphone. But don't let its size fool you because it's jam-packed with the latest home security technologies. The system arrived factory pre-configured. All I needed to do was plug it in, and it was up and running in no time at all. If needed, adding more components is possible using the system control panel, as shown in the sales support video clips. Once the system was turned on and pairing activated, the popular Alexa and SmartLife apps immediately detected it. The Alexa app only allowed me to arm or disarm it. On the other hand, not only did the SmartLife app allow me to do that, but it also let me change some of the system's settings, such as entrance or exit delays, siren duration, etc. I am very happy with this home security system and do not hesitate to recommend it, especially if you already have the SmartLife app installed on your smartphone and want to be able to not only arm or disarm this security system but also change some of its settings remotely.

I set up the Home Security Systems alarm with its GSM 4G plus Wi-Fi a 4.3 inch touch screen app alerts wireless motion sensors and door sensors right in my home office. Setup stayed manageable alerts arrived quick enough. A door sensor went off and my phone buzzed at once the screen lit up to mark the tripped zone so no guessing needed. The DIY side suits me fine you skip waiting on installers and it links with Alexa if that fits. I tested the SOS button once it handled straight from the panel. Placement still counts though for any wireless setup. A sensor in weak signal or strange angle can lag or miss so repositioning comes up while sorting it all out. Value holds because app alerts and the cellular Wi-Fi backup arrive without fees piling up durability looks solid sensors manage daily wear. I placed units on entry doors and motion spots near the office. That cut the usual did we lock it worry pretty fast.

I’ve been using this home security alarm system, and it has been an excellent addition to my home security. The touch screen is easy to read and makes the system simple to navigate, while the WiFi connection options give me added confidence that alerts can come through when needed. I really like that it works with the app for instant notifications, and the SOS feature adds an extra layer of reassurance. The wireless motion and door sensors made setup convenient, and I appreciate that it is a DIY system with no monthly fee. It feels useful, well designed, and made with quality materials, especially for the price. It also works with Alexa, which makes it even more convenient for everyday use. Recommended!

I’m giving this system three stars because it really is a great idea, but it falls short in some important areas. The biggest issue is that it doesn’t link to any actual emergency numbers, since there’s no subscription service. That part is nice in theory — no monthly fees — but it also means you’re not getting true monitored security.Another downside is the lack of instructions. Ours came with almost no guidance on how to install or use it. We had to look up YouTube videos just to figure out the setup, and we still have one piece left over that plugs into something, but we have no idea what it’s for. That’s not exactly confidence‑inspiring for a home security product.That said, I’m giving it three stars because the system does work perfectly as a basic alert setup. If all you want is to hear when doors open and close, it does that job well. The sensors are responsive, and the alarm is loud enough to notice. My favorite part is the RFID keychain tags. Being able to arm and disarm the system with a quick tap instead of typing in a code is genuinely convenient and feels more modern than some higher‑priced systems. Overall, it’s a good option for simple awareness inside the house, but if you want something that connects to emergency services or offers real security features, I’d go with a different system.

Installation of this alarm was rather easy. The company has some customer service, but we didn't need any assistance. It has a high decibel alert system along with a timer, a app and it is set in multiple languages with a built-in backup battery into a voice intercom. There's no subscription fee although you can upgrade and you can also use this- meaning it's compatible with smartlink and Google as well as a few others. My only complaint is in the data privacy. Read over everything, and if this is for you then add some security to your house. It's very easy to use and the app is fairly user friendly although not as simplified as say ring. The price is affordable and overall I would rate this a 4 out of 5 stars.
