Think in layers, not one big fix
No single gadget stops a determined intruder. What works is making each step slower, noisier and more visible, so that most would-be thieves give up and move on.
Picture four layers: your boundary (wall, fence, gate), the outside of the house (doors, windows, lighting), the inside (alarm, safe spots) and you (habits and neighbours). A weakness in one layer is covered by the next.
- Boundary: slows people down and blocks the view of what is worth taking.
- Building: strong doors and window protection decide how long entry takes.
- Detection: alarms and lights make noise and attention.
- People: routines, neighbours and a plan decide how well you respond.
Walk the property like an intruder
Do this once in daylight and once at night. Look for the easiest way in, not the most dramatic one. Check the easy ways in first: an unlocked door, an unprotected window or a weak back door.
Check what helps a person climb: wheelie bins against a wall, a tree touching the roof, a stacked pile of bricks. Check where someone could hide from the street while working on a lock.
- Count every door and window that opens, including the small bathroom window.
- Note any gap where a hand can reach a latch or key through burglar bars.
- Look at the gate and garage: is the remote on your car visor or in plain view?
- Check that the lights near each entry point actually work.
Doors, windows and locks
Exterior doors should be solid, with a sturdy frame and a lock fitted properly into it. A strong door in a weak frame fails at the frame. Security gates over the front and back doors add time, but only if you lock them whenever you are in the house too.
Burglar bars and window locks help most when the gaps are narrow and the fixings are secured into masonry, not just the wood. Keep spare keys away from the obvious hiding places such as under the mat or a nearby plant pot.
- Lock inside doors that lead to the bedrooms at night if your layout allows it.
- Keep a set of keys by your bed so you can leave the house quickly in a fire.
- Change locks when you move into a new home or lose a key.
- Do not leave ladders, tools or garden furniture where they help a climber.
Lighting, alarms and cameras
Light at doors and corners makes people think twice, and it helps neighbours see what is happening. Motion lighting is cheap and useful. A working alarm with a loud siren is a strong deterrent, because intruders do not want to be heard.
Cameras are most useful when you can see the footage on your phone and when the picture is clear enough to recognise a person. They record events; they do not stop them. If you pay for an armed or unarmed response service, confirm in writing what the response actually is and who is responsible for the alarm monitoring.
Habits that cost nothing
Many break-ins happen at times a routine is predictable: when the house is empty, at the school run, or while someone is in the garden with the front door open. Small habits remove those chances.
Be careful about who you let in. Ask for ID from anyone you did not call, and phone their company on a number you look up yourself. Be careful on social media about posting that you are away.
- Lock the gate and front door even when you are at home in the garden.
- Do not leave windows open when you go out, even for a short time.
- Do not leave bags, laptops or phones visible through a window.
- Take in washing and bins; a house that looks lived in is a harder target.
- Ask a trusted neighbour to collect post and park in your drive when you travel.
If someone gets in
Your life matters more than your property. Do not confront anyone and do not chase. If you can do so safely, move to a room with a lockable door, call the police and stay quiet and calm.
Keep the police emergency number, 10111, saved in your phone and on the fridge. If you want to pass on information about a crime without giving your name, Crime Stop takes tip-offs on 08600 10111.
A simple checklist
Use this list once a month. It takes about ten minutes.
- All outside doors and gates lock properly and are used.
- Outside lights work and cover each entrance.
- Alarm batteries and armed settings are tested.
- Spare keys are held by someone you trust, not hidden outside.
- Emergency numbers are saved and everyone at home knows the plan.
- You know your neighbours' numbers and they know yours.
- Valuables are in a safe or out of sight, and serial numbers are written down.
Questions people ask
What is the cheapest thing that makes a home safer?
Using the locks and gates you already have, every time, plus working outside lights. Easy ways in, such as an unlocked door or window, are the first thing to fix.
Do I need an alarm and a response service?
An alarm helps, and a response service adds to it. Neither replaces good locks. Ask any provider in writing what exactly happens when the alarm goes off.
What number do I call in an emergency?
Call SAPS on 10111 in an emergency. If you only want to give a tip-off without your name, Crime Stop is 08600 10111.
