Keeping your home safe is a top priority, but even with the best intentions, many homeowners leave themselves vulnerable by making simple, avoidable mistakes. At WDT Security, we’ve seen it all – from outdated alarms to poor CCTV coverage – and we’re here to help you stay one step ahead of potential intruders.

Here are some of the most common home security mistakes we come across, and how to fix them.

1. Forgetting to Set the Alarm

It might sound obvious, but you’d be surprised how often people forget to actually arm their security system – especially if they're just popping out for a short time.

How to avoid it: Make it a habit to set your alarm, even if you're only leaving for 10 minutes. Most modern systems, like the ones we install, can be controlled from your phone using an app – so you can arm or disarm the system remotely, no matter where you are.

2. Poor CCTV Camera Placement

CCTV is a brilliant deterrent – if it's installed properly. We've seen cameras pointing at walls, set too high to catch faces, or placed where lighting causes glare at night.

How to avoid it: Have your CCTV system professionally installed. At WDT Security, we assess your property layout and lighting conditions to make sure your cameras give you clear, useful footage – day or night.

3. Leaving Spare Keys in Obvious Places

Under the doormat. In the flowerpot. On top of the meter box. These are the first places a burglar will check – and they know all the classic hiding spots.

How to avoid it: If you need to leave a key outside, invest in a secure key safe with a combination lock – and don’t forget to change the code regularly. Better still, consider a smart lock system for more control.

4. Relying Too Much on DIY Security

DIY alarm and CCTV kits are popular, but they often lack reliability and support. We've had customers come to us after a break-in, only to discover their system wasn't even recording properly.

How to avoid it: Use a professional security company (like us!) to install a system that’s built to last. We’ll make sure everything is set up correctly, configured for your property, and backed by proper support and maintenance.

5. Not Using the System’s Full Features

Modern alarms and CCTV systems come with loads of smart features – but if you're not using them, you’re not getting the full benefit.

How to avoid it: We always show our customers how to use their systems properly – from remote access and mobile notifications to setting up custom zones. If you’ve already got a system but don’t feel confident using it, we’re happy to help.

6. Lack of Deterrents

A visible security system is one of the biggest deterrents to would-be intruders. But some people have alarms with no external sounder, or cameras that aren't easy to spot.

How to avoid it: Make it obvious that your home is protected. Use signage, external bell boxes, and clearly placed cameras to let anyone passing by know your property is secure.

7. Outdated or Poorly Maintained Systems

Old systems can fail when you need them most. Faulty sensors, dead batteries, or broken cameras are all things we've seen leave people exposed.

How to avoid it: Book a regular service for your system. At WDT Security, we offer maintenance packages to keep everything running smoothly and catch problems before they become serious.

Final Thoughts

Home security doesn’t have to be complicated – but it does need to be done properly. Avoiding these common mistakes can make a big difference when it comes to protecting your home, your belongings, and your loved ones.
