20 Best security products under $25
Locks under $25
1. Defender Security Door Lock: Best for homes with kids
Most intruders know to attack a door at the lock—but what if your door had an extra lock in an unexpected place? The Defender Security Lock can easily be installed nearly anywhere on the inside edge of your door. It's easy to lock and unlock from the inside, but it's impossible to tamper with from the outside. Plus, you can place it high on the door so small kids can’t escape when it’s secured.
But it’s not a perfect fit for every door. You may need to get handy with a chisel to fit it on some doorways. You may also need to replace it after a few years of wear and tear. It’s a good idea to look for these on sale and buy a couple at a time so you can replace one as soon as it shows deterioration.
2. SABRE Door Security Bar: Best for added door security
If you're worried that your locks aren't secure enough, a door jammer security device like the SABRE Security Bar is a good option. It fits under your door handle and adjusts to the length you need. A rubber foot prevents the bar from sliding on your floor.
3. Defender Security Sliding Window Locks: Best for vinyl window security
Amazon.com list price as of post date. Read full disclaimer.
Standard window locks work well for keeping windows shut, but if you want to be able to keep your window partially open for ventilation, Defender’s Sliding Window Locks offer both protection and airflow. No screws required, just clamp it on to the window track at the desired location.
4. Lion Locks: Best for aluminum sliding doors/windows
Gripping pads on Lion Locks door and window locks keep them secure on any sliding door or window track. Double thumbscrews make installation easy and snug. Choosing the lock placement along the track lets you control how far your door or window opens.

6. Defender Sliding Door Security Bar: Best for sliding glass doors
The Defender Sliding Door Security Bar is just like your grandma's broomstick in the sliding door track, but with handy components like a hinge that makes it easy to lock and unlock without removing the entire thing and an adjustable telescoping length.
Alarms under $25
7. Taiker Personal Emergency Alarm: Best for deterring intruders
A whole-house alarm system with monitoring might not be in your budget, but there's no reason you can't still scare off intruders with a loud noise. A five-pack of push-button Taiker alarms is under $20, so you can stash one in every room of your house.
8. SABRE Shed and Garage Alarm: Best for garages and outbuildings
Even though the SABRE alarm is marketed for commercial doors, you can use it to secure any door in your home, including your garage or shed door. It's easy to arm and disarm with your own four-digit code, and you can choose between alarm and chime modes.
9. GE Personal Security Kit: Best for apartments or dorms
With three separate alarm components, the GE Personal Security Kit is a smart going-away present for any college student. It comes with a door/window sensor alarm, a keychain panic alarm, and a doorstop intrusion alarm. All are battery-operated and easy to arm and disarm.
10. GE Door/Window Alarms: Best for DIY home security systems
Door and window sensors like these GE window/door alarms can work almost as well as a full security system without monitoring. Just mount the sensor and the magnet and then select between "Alarm," "Chime," and "Off." The sensors' shrieking, 120-dB alarms will surprise any would-be intruders.
Lights and monitoring under $25
11. HMCity Outdoor Motion Sensor Solar Lights: Best for outdoor lighting

14. ZOSI 1080p CCTV Camera: Best for monitoring
When we found these cheap security cameras, we knew they had to be on the list. But the ZOSI 1080p CCTV Camera doesn't come with the needed DVR or cables, and the monitoring app for smartphones and tablets is difficult to use. Still, the cameras work well for monitoring in all weather conditions and come with lifetime tech support.
