Cheap Home Security Product Reviews

solar spotlight with solar panel

Mpow Solar Spotlight

Best for shining a light on dark pathways

Check Price on Amazon

Intruders literally bank on coming and going without being seen. But you can stop them in their tracks with this outdoor security spotlight. We’re big fans of Mpow’s solar spotlight because it’s motion-activated and relies on solar power for extra security in the event of a power outage.

Pros

  • High-efficiency solar panel
  • 45 ft. illumination range
  • Weatherproof design

Cons

  • Power concerns on cloudy days
  • Condensation creep in wet weather

doberman entry alarm

Doberman Security Entry Defense Alarm

Best for scaring off intruders

Check Price on Amazon

This door alarm has you covered with a 100-decibel siren—about as loud as a jackhammer—to scare burglars off before they can harm you or your home. Plus, the easy installation means you can start protecting your home in minutes.

Pros

  • Good customer reviews
  • Easy peel-and-stick installation
  • Siren that can be heard from over a mile away

Cons

  • No way to adjust siren volume
  • Incompatibility with some doors

security bar for patio door

Prime-Line Aluminum Patio Door Security Bar

Best for shoring up sliding glass doors

Check Price on Amazon

Weak locks and breakable glass make sliding glass doors easy access points for intruders. Add extra security with this aluminum bar that helps prevent a thief from prying open your sliding glass door. But don’t forget to keep patio doors and other sliding doors locked—a security bar isn’t enough protection on its own.

Pros

  • Lightweight aluminum construction
  • Strong steel frame
  • Different finishes to match décor

Cons

  • Confusing mounting instructions
  • No adjustability without cutting the rod

fake security camera with red LED lights

UniquExceptional Fake Security Camera

Best for sending the message that troublemakers are being watched

Check Price on Amazon

If a criminal thinks they’re being watched, there’s a good chance they’ll abandon their break-in attempt. That’s the whole idea behind UniquExceptional’s fake security camera. Install these “cameras” inside or outside your home to give the illusion that it’s protected with high-tech security.

Pros

  • Long-lasting battery power
  • Indoor or outdoor use
  • Real infrared lights

Cons

  • Not a real security camera

window over sink with etched glass window film on half the window

ARTSCAPE Etched Glass Window Film

Best for keeping out prying eyes

Check Price on Amazon

Visible valuables like electronics, jewelry, and nice furniture tempt curious trespassers to break into your home. But when you use Etched Glass Window Film, they won’t be able to see what’s inside or if anyone is there. This window film also offers privacy without blocking light—it just blocks nosey people who are up to no good.

Pros

  • Pre-cut to standard window size of 24 x 36 in.
  • Easy to apply, no sticky adhesive
  • Designed to simulate textured or stained glass

Cons

  • Doesn’t fortify glass
  • Isn’t as opaque as expected

close up view of peephole

Schlage One-Way Wide Angle Peephole

Best for knowing who’s at the door

Check Price on Amazon

Pros

  • Easy installation
  • One-way view
  • Excellent clarity

You can use the key or the three-digit combination lock to keep your handgun or other small valuables (like a passport) safe from little ones or thieves.

Pros

  • Keyless entry with combo lock
  • 16 ga steel housing
  • Security cable included

white alarm with four numbered buttons and one round button

SABRE Shed and Garage Alarm

Best for thwarting sneaky outdoor intruders

Check Price on Amazon

Thieves break into garages in under six minutes, on average, and smaller sheds in even less time. The SABRE Shed and Garage Alarm is your defense against these kinds of attacks, because the sensors sound an ear-piercing alarm when they detect motion. Plus, SABRE’s alarm is better than most because it has a combination keypad, so you’re the only one who can turn off the alarm—not sneaky intruders.

Pros

  • Easy installation
  • Multiple sound modes
  • Secure arm/disarm function

Cons

  • Some vulnerability to tampering
  • 30-sec. delay before alarm sounds

brass door strike plate

Defender Security Combo Deadlatch and Deadbolt Strike Plate

Deadbolts are built to last, but they can’t do their job if the rest of your door is vulnerable to kicking, prying, and ramming. The solution? Replace your deadbolt strike-and-latch with Defender Security’s hardware to prevent thieves from entering with force. The long screws included with this product add extra strength and durability to a potentially weak portion of your door.

Pros

  • Steel construction
  • Brass finish

Pros

  • Perfect for renters or roommates
  • Equipped with 120 dB siren
