Grilles and Shutters

Grilles and shutters are window protection similar to bars in that they offer security through obstruction; essentially, they prevent a criminal from accessing the window to attempt a break-in.
Grilles are attractive metalwork that is installed on the interior or exterior of the glass, providing artistic curb appeal to the home and preventing anyone from entering through the window.
As with window bars, it’s important to make sure there’s a way to remove them to exit through the window if necessary, but they provide excellent security.
Shutters do the same. Security plantation shutters can be closed and latched (and sometimes locked) to cover the window and prevent access while obstructing the view, but they fit stylistically with the appearance of the home.
Roll-down shutters, similar to what storefronts use, can be attractively disguised on the outside as a blind or roller shade, but they are actually fitted into a track from which they can’t be dislodged once they’re locked in place.
Both of these solutions require measuring, professional installation, and some upkeep, but they offer the security of bars without the prison vibe.
Pros and cons of grilles and shutters
Grilles and shutters have their own set of pros and cons. Grilles are typically less expensive than shutters, and they can be installed on the interior or exterior of the window.
However, they may obstruct the view and can be difficult to clean.
Shutters, on the other hand, can be more expensive and require professional installation, but they can also provide added insulation and noise reduction while enhancing the appearance of your home.
Window Security Films
Another effective way to secure windows without bars is to use window security film. This thin, tear-resistant film is applied over your existing windows and strengthens the glass to prevent break-ins.
It makes the windows much more difficult to penetrate and slows burglars down, often enough to make them give up and move on to easier targets.
Window security films not only make your windows more secure but also have other benefits. They can protect against UV rays, reduce glare, and even provide protection from flying glass during natural disasters.
They can be easily applied and removed and come in a variety of styles, including tinted, frosted, decorative, or clear.
There are several types of window security films available, including:
- Tinted/black
- Frosted white
- Decorative
- Clear
Choose the type that best suits your needs and style preferences.
Window Locks
Window locks are another viable alternative or addition to window film, bars, or home alarms.
Supplemental window locks can be added to most types of windows and can help prevent break-ins.
There are several types of window locks available, including flip locks, turnbuckles, and sliding window locks.
Flip locks are the most common window lock hardware that comes with windows, but turnbuckles require that you squeeze a lever while turning the latch, or unlock the lever with a key, in order to open.
Window locks are a cost-effective way to secure your windows without compromising their appearance.
They can be easily installed and come in a variety of types to suit different window styles.
However, they may not be as effective as other window security measures and may not deter determined burglars.
Polycarbonate Safety Shields
One of the best ways to burglar-proof windows is to install polycarbonate safety shields, like DefenseLite, over your existing windows.
Polycarbonate is 250 times stronger than glass and nearly impenetrable by would-be thieves.
Polycarbonate safety shields provide excellent protection against break-ins while maintaining the appearance of your windows.
They can be custom-cut to fit any size window and are highly resistant to impact, making them almost impossible for burglars to break through.
Additionally, polycarbonate shields are lightweight and easy to clean, making them a low-maintenance option.
Installation and maintenance of polycarbonate safety shields
Installation of polycarbonate safety shields typically requires professional help, as they need to be securely fitted to your existing windows.
However, once installed, they require very little maintenance. Regular cleaning with a soft cloth and mild detergent is usually all that’s needed to keep them looking their best.
Motion Sensor Lights

Motion sensor lights are an excellent way to deter potential intruders while providing extra security for your home.
These lights automatically turn on when they detect movement, startling would-be burglars and alerting you or your neighbors to their presence.
There are several benefits to installing motion sensor lights around your home, including:
- Deterrence: The sudden illumination can make criminals think twice before attempting a break-in.
- Increased visibility: Well-lit areas make it easier to spot intruders, both for you and your neighbors.
- Energy efficiency: Motion sensor lights only turn on when needed, saving energy compared to traditional outdoor lighting.
Installation and maintenance of motion sensor lights
Installing motion sensor lights is relatively straightforward and can typically be done by most homeowners. Choose strategic locations around your home’s exterior, such as near entry points or dark corners.
Be sure to follow the manufacturer’s instructions for proper installation and maintenance. Regularly check the lights to ensure they are functioning correctly and replace bulbs as needed.
Security Cameras

Security cameras serve as both a deterrent and a means of gathering evidence in the event of a break-in.
Modern security cameras come in a variety of styles, from discreet doorbell cameras to more visible outdoor cameras, and can be connected to your home’s Wi-Fi network for remote monitoring.
There are several benefits to installing security cameras around your home, including:
- Deterrence: The presence of security cameras can make burglars think twice before attempting a break-in.
- Evidence collection: In the event of a break-in, security cameras can provide valuable evidence to help law enforcement catch the culprits.
- Remote monitoring: Many security cameras can be accessed remotely through a smartphone app or web interface, allowing you to keep an eye on your home even when you’re away.
Types of security cameras available
There are several types of security cameras available on the market, including:
- Doorbell cameras
- Outdoor cameras
- Indoor cameras
- Wireless cameras
- Wired cameras
Choose the type that best suits your needs and preferences.
Be sure to consider factors such as image quality, storage options, and compatibility with your existing home security system.
