GE 45989 Personal Window/Door Security Off/Chime/Alarm
Perfect for home, garage, apartment, dorm room, mobile home, RV, office and more
This 12-pack of GE security sensors is easy to set up and requires no wiring, which makes it an ideal choice for renters and anyone who doesn't want to deal with potential wiring issues. They're also easy to install, and the GE alarm has all the features you need, including two volume settings (off/chime/alarm), a low battery test button, and a tamper alert. The GE alarms have a loud, visible alarm output and are easy to set. The GE alarms also do one thing our top picks don't: They support two triggers, so you can set an alarm when a window or door is left open, or you can also set an alarm when the door or window is opened or closed. The GE alarms also sound a loud chime when a door or window is opened, which is a useful feature. But, the GE alarms aren't as reliable as the top picks, and they also have a shorter battery life.

SABRE HS-DSA Wedge Door Stop Security Alarm 120 with dB Siren --- Great for Home
VERSATILE WITH MAXIMUM SECURITY features a non-skid pad to prevent door from opening while alarm sounds; ideal for bedrooms, hotels, apartments, dorm rooms, front doors, etc. - great travel alarm
The Sabre HS-DSA Wedge Door Stop Security Alarm with 120 dB Siren looks great, it's easy to install, and it functions as a security alarm and a door stop. The alarm activates when the door is under pressure, which should help deter intruders from breaking in. It's also loud enough to potentially wake or alert someone inside. The alarm's 120 dB siren is loud, too, loud enough to potentially alert neighbors and passersby. The alarm's battery status light lets you know when it's time to change the battery. But our biggest gripe is that the alarm's door stop function is inconvenient. When you open the door, the alarm activates, which not only alerts you that someone is entering your home, but the alarm also continues to go off until you deactivate it. It's annoying, and we wish it had a dedicated deactivation button. The alarm's mounting brackets are awkward, too, and we'd prefer a more secure mounting option. But overall, the Sabre HS-DSA Wedge Door Stop Security Alarm with 120 dB Siren is an attractive, high-quality home security device.

Easy installation(2.4GHz Network): All accessories in the set are already paired before leaving the factory. This door alarm built in a Bluetooth module. As long as your router supports a 2.4GHz network, you can easily connect to the network by turning on the Bluetooth of your phone and following the instructions.
The CPVAN WiFi Door Alarm System (2nd Gen) offers impressive range, easy to install, and a variety of compatible accessories. The smartlife app is intuitive and easy to use, and the alarm itself sounds decently loud, though you'll definitely want to keep it out of your baby's earshot. Pros include the app's intuitive and easy-to-set up interface, which you can personalize for different zones in your home. It also allows you to set different ringtones for each of your sensors, so you can tell which door has been opened. The smartlife app also lets you control other smarthome devices (such as lights and switches) that connect to the hub. Cons include the hub's relatively limited range of about 500 feet, and the fact that the hub can't send alerts via text message or phone call. The hub also lacks a siren, so you'll have to rely on the mobile app for any alerts. The hub's $40 price tag is a little steep, but considering its versatility, its range, and its convenient smarthome integration, we think it's worth it.

HENDUN Wireless Door Alarm with Remote
Easy to install and operate - pool/gate/door alarm with remote
The $28 HENDUN wireless door alarm is easy to install, so it's perfect for renters and retirees. This alarm is compact and unobtrusive, and it can be set to sound only while you're at home, so it doesn't disturb other people. The alarm also alerts you to windows or interior doors being opened, so you'll know if your kids, elderly relatives, or houseguests have wandered off or wandered into danger. The alarm is easy to set up, and the alarm settings can be adjusted with the remote control. The alarm can be removed from the wall and recharged, so you'll never have to worry about a dead battery. The alarm's magnetic sensors aren't very sensitive, so you'll still need to monitor your children or elderly relatives, but it's better than having an alarm with no sensors. The alarm isn't wireless, so you can't place the alarm anywhere you want. The alarm also emits a shrill, high-pitched sound, so it's annoying if you have a quiet household.
