In brief: Effective home security starts with mechanical protection at vulnerable points. Windows and doors need sturdy mushroom-head bolts or crossbars. Burglary-resistant cylinders and security fittings are essential. Combine these with a visible alarm system and consistent outdoor lighting. Even a few measures significantly increase the effort for burglars and act as a deterrent.
Home security: Where should you start?
The thought of a burglary is unsettling. Many homeowners wonder where to begin. The answer is simpler than you might think. Start with the typical entry points. More than 80 per cent of burglaries occur through ground-floor windows and doors.
Focus your resources on these weak points first. A thick security door is of little use if the window next to it has only a simple latch. A systematic check of your home's exterior is the first step.
Look at your home from a burglar's perspective. Where is it dark? Which window is hidden? Which door looks weakest? This analysis shows you the areas that need attention most urgently.
Analysing weak points: windows and doors
Windows are the most common entry point. Check the fittings. Older windows often have only simple locking bolts. A screwdriver can force them open in seconds. Modern mushroom-head or hook bolts rotate with the mechanism and provide resistance.
With doors, the cylinder is the key component. Cheap cylinders with standard profiles can be broken with pliers. Security cylinders with protective fittings and drill protection make this type of attack impossible. The door leaf and hinges must also be sturdy.
A burglar typically spends only three to four minutes inside a property. Every second they lose forcing their way in puts them at risk and increases the likelihood that they will abandon the attempt.
How can I secure my windows effectively?
Being able to lock your window handles is the minimum requirement. But that is not enough. Breaking the glass completely bypasses the locked handle. Protection has two components: the fittings and the glazing.
Retrofitted solutions such as lockable window handles and additional bolts for the window sash are a good start. For greater security, install burglary-resistant glazing. It consists of laminated glass that does not give way even when struck.
Pro tip
Check the gap between the sash and frame on every window. If it is wider than 2 mm, levering tools can be inserted. Retrofitted security fittings with long hook bolts close this gap and effectively prevent the window from being forced open.
Do not forget shutters or blinds. A raised shutter signals that nobody is home. A lowered shutter provides privacy and another mechanical barrier. Secure shutter boxes from the inside with special bolts.

Choosing the right glazing
Burglary-resistant glass can be identified by the designation ESG/PVB or by its RC resistance class. RC 2 glass withstands several powerful blows from a heavy tool. For typical detached houses, this class is a good standard.
Glazing alone is not a complete solution. It must be combined with secure fittings. Otherwise, the intruder can simply push the entire sash out of the frame. A complete system consisting of a strong frame, sturdy hinges and the right glazing provides protection.
Why is the front door the most important point?
The front door is the most obvious target. It must withstand physical attack. This starts with the material. Solid wood doors or fully reinforced steel doors are more robust than lightweight veneered wooden doors.
The frame is just as critical. It must be firmly anchored in the masonry. Burglars often kick doors out of the frame with a targeted blow next to the lock. Reinforce this area with long, strong screws that reach deep into the wall.
Locking systems make the difference. A multipoint locking system with at least three bolts distributes the force across the entire door frame. A simple latch-bolt lock offers very little protection.
Important note
Never leave your front door key inside the lock. With many doors, a burglar can reach the slot from outside, for example through the letterbox slot or a pane of glass, and simply turn the key. Always remove the key.
A door viewer, or better still, a video door entry system gives you control before you open the door. You can see who is outside without putting yourself at risk. This technology is now affordable and easy to install.
The psychological barrier is just as important as the mechanical one. A house that actively signals security — through flashing lights at the windows, visible cameras or a dog — is more likely to be bypassed. The intruder looks for an easy target.
Technical security: Should you install an alarm system?
An alarm system is not an alternative to mechanical security. It is an addition. Its main purpose is to drive the intruder away once they have entered and call for help.
The visible components act as a deterrent. A well-positioned external siren and flashing lights signal that the house is protected. Invisible indoor detectors such as motion sensors or glass-break sensors trigger in an emergency.
Modern systems are wirelessly connected and require very little cabling. You can often install them yourself. Make sure the alarm system has redundant alerting, for example via GSM and the internet. Cutting a cable should not disable the system.
Smart security while you are away
Smart home components offer new possibilities. You receive push notifications on your smartphone when the alarm is triggered. You can view live images from your security camera. You can switch the lights on remotely.
This convenience comes at a price: IT security. Every connected device is a potential gateway for hackers. Separate your security network from the rest of your Wi-Fi. Always use strong, unique passwords.
Additional advice
Make it look as though someone is home when you are away. Timers for lights and radios are classic but effective. Ask a neighbour to empty the letterbox and move the car occasionally. A well-maintained outdoor area makes the home look occupied. An overflowing letterbox and long grass are inviting.
For protecting your valuables at home, a special safe is a good choice. The

What protects my property and garden?
Security starts at the property boundary. A clearly defined boundary with a well-maintained fence signals privacy. An open front garden with good visibility offers burglars no cover.
Light is your best ally in the dark. Motion sensors with LED floodlights at all entrances and dark corners switch on when someone approaches. This surprises the intruder and makes them visible. Solar-powered solutions are ideal for this and require no cables.
Valuable garden equipment is a popular target for thieves. Store lawnmowers, bicycles and your barbecue in a locked shed. Secure the shed itself with a security padlock. Chain large equipment to something secure inside.

Choose the right lighting
Leaving lights on continuously is outdated. They cause glare, use electricity and make neighbours get used to the light. Smart motion sensors with built-in timers are the solution. They only switch on when someone approaches the house.
Install lights at a suitable height. A sensor three metres above the ground is difficult to tamper with. Position the floodlights so they illuminate the area without dazzling passing neighbours.
Fire safety as part of home security
Security means more than protection from burglars. A fire can destroy your home just as easily. A working fire extinguisher in strategic locations such as the kitchen, garage and hallway is essential.
Especially in the kitchen, where grease fires can occur, a special extinguisher is essential. A
Smoke alarms in all bedrooms and living areas are required by law in most German federal states. Test the devices every month by pressing the test button. Replace the batteries according to the manufacturer's instructions.

Everyday habits that help keep you safe
Security is a routine. Whenever you leave the house, close all windows, including those on upper floors. An open roof window can provide an entry point for a climber.
Do not keep spare keys under the doormat or in a plant pot. Give spare keys only to trusted neighbours. Consider using an electronic key safe with a code.
Be discreet on social media. Do not post live updates from your holiday. Do not publicly share the full duration of your absence. The internet is the first source of information for opportunistic criminals.
Activate neighbourhood watch
A vigilant neighbourhood is a free and highly effective form of protection. Exchange phone numbers. Agree to check with one another about unfamiliar tradespeople or suspicious vehicles.
Many local authorities offer neighbourhood watch schemes or security partnerships. There you can receive up-to-date information about your neighbourhood and practical advice from the police.
Ultimately, burglary protection is not a one-off purchase but an attitude. Start with the mechanical basics for windows and doors. Add visible deterrents such as lighting and alarm systems. Store important documents in a . Keep your gardening tools sharp with a robust
(Wonder Scissors) to keep hedges and shrubs short, which could otherwise provide cover for intruders. Stay alert in your everyday life and trust your instincts when something feels wrong.
Frequently Asked Questions
- Which type of window is safest against burglary?
- The safest option is a modern window with burglary-resistant glazing (ESG/PVB) and a lockable fitting rated RC 2 or higher. The combination of robust hardware and toughened glass is important. Older windows can often be significantly upgraded with retrofitted mushroom-head locking bolts on the handle side.
- How much does a good alarm system cost for a detached house?
- The hardware for a complete alarm system with perimeter protection, indoor detectors and a GSM module for a detached house starts at around 1500 to 3000 Euro. Professional installation costs a further 500 to 1500 Euro. Simple wirelessly connected DIY kits are available from 400 Euro.
- Does a dog flap or a dog help protect against burglary?
- A dog in the home is an effective, living alarm and deters many intruders. An open dog flap or door, however, weakens your door. Choose special lockable security flaps that open only for your pet and can be locked at night. A dog's presence alone is no substitute for mechanical security measures.
- Are smart cameras and video doorbells safe from hackers?
- Smart devices pose security risks. Choose established manufacturers that provide regular security updates. Separate your IoT network from your main Wi-Fi, use strong, unique passwords and enable two-factor authentication. A hacked camera becomes a spying tool and compromises all your other security measures.
- What is the most common home security mistake?
- The most common mistake is neglecting simple mechanical security basics. Many people focus on expensive technology but leave windows with standard locking bolts or doors with cheap cylinders unsecured. An intruder needs only seconds to overcome these weak points before an alarm can even be triggered.
