If you’re looking for a basic—extremely basic—DIY security system, take a look at X-Sense. The company, best known for its range of smoke detectors, offers a bare-bones system that works fairly well and costs next to nothing.
The X-Sense Home Security Kit is available in two versions: There’s the $130, 5-piece kit reviewed here, which includes a hub, motion sensor, two door/window sensors, and a remote-control key fob. An extra $40 will get you X-Sense’s 8-piece kit, which adds an additional motion sensor and two more door/window sensors. The only additional sensor type that works with the system is its Wi-Fi Smoke Detector, which is sold separately.
This review is part of TechHive’s coverage of the best smart home systems, where you’ll find reviews of the competition’s offerings, plus a buyer’s guide to the features you should consider when shopping for this type of product.
The centerpiece of the kit is the hub, a stylish, cube-like device with a light-ring around top that denotes the alarm status. Aside from serving as the connecting point for sensors (up to 32 sensors and 6 remote controls are supported), the device includes a siren (reasonably loud, though a dB rating is not provided) and a battery that provides up to 12 hours of backup if the power goes out. There is no LTE backup should your broadband connection fail.
The unit connects to your home network via 2.4GHz Wi-Fi (only), but it connects to sensors via a long-range RF connection using an unspecified protocol. The company says it can detect sensor pings for up to 1.25 miles (line of sight); in real-world testing (with the typical suburban obstructions), I was able to achieve a sensor range of about 400 feet.

The sensors are big and bulky, in part because each one relies on a large 3-volt battery for power. On the plus side, this can provide a lifespan of up to 3 years, per X-Sense, though they certainly won’t do a lot for your décor.
Setting up the hub and sensors is a relatively painless process that involves installing the battery, scanning a QR code with the X-Sense Security app, and pressing a button on the device when prompted. The next steps are typical: Assign each sensor to a room and give it a name, after which the system is up and running.
A handful of small extra settings are available if you dig around in the menus, including the option to play one of a variety of chimes when doors are opened or motion is detected, and the inclusion of five sensitivity levels on the motion sensor. A history pane logs all activity, with each day recorded separately.
The system offers the usual three operational modes: Disarmed (nothing is recorded, but the chimes still ping); Home (system is armed and sensor trips are logged, but the alarm does not sound); and Away (the alarm sounds when any sensor is tripped). Each mode can each be tweaked a bit, so if you want home mode to sound when doors are opened but not on motion detection, that’s easy to set up.
All of this works fitfully, though it’s never as solid as some of the more mature alarm system options on the market. The app is prone to getting stuck with doors listed as “open” when they are closed, and it can sometimes lose its connection to the app altogether. There can also be a significant delay in relaying commands from the app to the hub, particularly when you’re trying to disarm the system after coming inside and the entry delay countdown is active. Worst of all, on multiple occasions the siren went off after I had put the system into “disarm” mode and received an audio confirmation of that from the hub; I even encountered this type of random siren behavior after I had disabled sirens altogether.
False alarms like this are a pain, but they might be less of a headache than with other security systems, because aside from the siren, the only communication the system offers is push notifications to your phone. There’s no email/text option and, notably, no professional monitoring service offered, either. (X-Sense didn’t even know what that was when I asked about it.) There’s no connection to third-party services like Alexa, either.
That said, this is a system that is designed to be affordable and easy to use; something which covers the basics and nothing more. On that front, it succeeds well enough. If you want a more sophisticated and more reliable DIY home security system—with the option of professional monitoring—take a look at the offerings from Abode, Ring, or SimpliSafe.
