To increase home security, start by thinking like a burglar and walking the perimeter of your property to spot every weak point before you buy a single lock or camera. A thorough vulnerability audit reveals exactly where your home is most exposed, allowing you to prioritize the fixes that will actually deter an intruder.
How to increase home security with a vulnerability audit
Begin your audit by examining every entry point. Check each door for gaps between the frame and the door itself, test the fit of the strike plate, and inspect the condition of the hinges. Look at windows for cracked frames, loose latches, or single-pane glass that could be shattered easily. Move outside and study your landscaping: overgrown shrubs and trees near doors and windows create perfect hiding spots for someone waiting to break in. Evaluate your existing lighting, noting any dark corners or shadows that could conceal movement. Finally, test every lock on your property, including sliding door latches and garage entry locks, to identify which ones are flimsy, broken, or outdated. This audit gives you a clear list of what needs to be addressed first.
Reinforce doors and locks to prevent forced entry
Replace old-fashioned chain locks and avoid pushbutton doorknob locks, as they offer false or insufficient security; instead, install wide-angle peepholes in all entry doors so you can see who is outside without opening the door. Upgrade to high-quality deadbolts with a one-inch throw bolt and pair them with heavy-duty strike plates secured by long screws that reach into the door frame's stud. For sliding glass doors, place a metal rod or dowel in the track to prevent the door from being forced open, and consider adding a security screen door as an additional barrier at your main entrance.
Secure Windows with film, locks, and pins
Secure all windows with working key locks or pins, and consider applying shatter-resistant security film or installing laminated glass to deter forced entry. The film holds glass together when struck, making it much harder for an intruder to smash through quickly. For windows on the ground floor or near a porch roof, add security bars that can be released from the inside in case of an emergency, ensuring you are not trapped during a fire. Test every window lock seasonally to confirm it engages fully and replace any that are stiff or broken.
Install and position security cameras correctly
Strategically place security cameras to cover all entrances and exits, mounting outdoor cameras 8-10 feet high to avoid tampering and ensuring they avoid backlighting for clear images. A camera pointed toward a bright window or direct sunlight will produce a washed-out, unusable feed, so angle them away from strong light sources. Place visible signage indicating the presence of security cameras on your property, as the combination of a visible camera and a sign is a powerful deterrent. For maximum coverage, position cameras at corners where they can see two sides of the house at once.
Use smart home tech and secure your network
Consider installing a professionally monitored home security system, as visible alarms and signs act as powerful deterrents. When you set up smart home devices, you must also secure the network they rely on. Secure your Wi-Fi network using WPA3 encryption (or WPA2 at minimum), change default admin credentials, and create a separate guest network for IoT devices to isolate them from your main network. Use strong, unique passwords for every smart home device and enable two-factor authentication (2FA) wherever possible to prevent unauthorized access. Keep firmware and software updated on all smart devices, enabling automatic updates if available, as unpatched devices are open to attackers. Regularly audit your connected devices and remove any forgotten or unused ones, as they can become silent security liabilities. A compromised smart lock or camera can give a burglar a virtual key to your home, so knowing how to properly set up home security cameras with encrypted feeds and secure mounting is essential.
Add outdoor lighting and eliminate hiding spots
Trim shrubs and trees around doors and windows to eliminate hiding spots for potential intruders and improve visibility. Install motion-sensor lights at every entry point, including the back door, garage, and side gates, so that anyone approaching triggers a sudden flood of light. Position lights to cover dark pathways and eliminate shadows where someone could crouch unseen. For the best effect, combine motion-activated floodlights with low-level ambient lighting that stays on all night, creating a well-lit perimeter that makes covert approach nearly impossible.
Safeguard valuables and create an emergency plan
Invest in a high-quality safe that is securely bolted to the floor or wall to protect jewelry, cash, passports, and important documents. Create a detailed home inventory with serial numbers, photos, and receipts for all valuable items, storing that information in a secure digital location or off-site. Develop a family emergency plan that covers what to do during a break-in, including a safe room, a meeting point outside, and how to contact emergency services. Practice the plan with all household members so that everyone knows their role without having to think during a stressful event.
Maintain security and build community vigilance
Regularly test your alarm system, motion sensors, and camera feeds to confirm everything is working. Change batteries in all wireless devices at least once a year, and update access codes and passwords for keyless entry systems and smart devices every few months. Make your home appear occupied by arranging for mail and newspaper collection and maintaining your lawn if you are away for an extended time. Connect with your neighbors and consider forming a neighborhood watch program, sharing information about suspicious activity and looking out for each other's properties. A community that communicates is far harder for criminals to target than a street of isolated homes. Apply the principle of unique, complex passwords to every device and service connected to your home security system.
