The 10 best home security measures for your house

Keeping your home secure isn’t just about luck or having a good lock. It’s about combining prevention, common sense and the right technology.

Below, you’ll find the 10 best home security measures, with practical advice you can start using today—whether you live there all year round or only part of the year.

1. Install secure doors and windows

Your home’s first line of defence is its access points. A reinforced or high-security door doesn’t just deter intruders—it slows them down if they try to force entry.

A Grade 3 security door or higher (under UNE-EN 1627 standards) can withstand more than 5 minutes of direct attack. That may not sound like much, but it’s critical—most intruders give up if they can’t get in quickly.

For windows, multipoint locks and laminated glass (3+3 or higher) add extra resistance. If you live on a ground floor or have a terrace, install fixed or hinged bars and check the fixings every year.

According to Spain’s Security Observatory, over 80% of home burglaries happen through the front door or windows (55% and 28.3% respectively). A small upgrade can prevent a major problem.

2. Identify weak points and reinforce them

Every home is different, so your approach to home security should be tailored to your space. Before investing in expensive systems, carry out a full check:

• Which access points are most vulnerable?
• Are there dark or hidden areas?
• Can people see inside from the street?

Don’t forget garages, storage rooms or patios—secondary entrances are often overlooked. A motion-sensor light or a smart lock can make a real difference.

A useful exercise is to walk around your home and imagine trying to get in without keys. What you notice will give you valuable insights.

3. Install a security system and make it visible

The most effective way to ensure full home security is with a connected alarm system. Today, installation is quick and affordable, especially with services like Olin Protect, which include cameras, sensors and 24/7 monitoring.

There’s one key detail: make it visible. Stickers, sirens and visible detectors act as strong deterrents.

Modern systems also let you control everything from your phone, receive real-time alerts and check live footage—ideal if you’re away for long periods.

4. Create an inventory of valuable items

No one likes to think about theft, but being prepared makes a big difference.

Create a list—or better, a digital file—with photos, serial numbers and descriptions of your valuables: jewellery, watches, electronics, artwork…

Store this information securely in the cloud or in an encrypted folder. It will help prove ownership and speed up insurance claims or police reports.

This simple step strengthens your home security and reduces both financial and emotional impact if something happens.

5. Use a safe for important items

Not all home security measures rely on technology. Sometimes, the most traditional solutions are still the most effective. A built-in, well-hidden safe is one of the best ways to protect documents, cash and valuables.

Choose one certified under UNE EN 1143-1 for proven resistance. Avoid portable or decorative safes—they don’t offer real protection.

Install it in a discreet location and don’t share its position. If you connect it to your alarm system, even better.

6. Make your home look occupied when you’re away

An empty house sends clear signals: shutters down for weeks, a full letterbox or no lights. To improve security while you’re away, use timers for lights and blinds or ask a neighbour to collect your mail.

Small actions like these make your home look lived-in and reduce the risk of being targeted.

7. Don’t share your absence on social media

This is one of the most common—and easiest to avoid—mistakes. Posting in real time that you’re away can put your home at risk.

Adjust your privacy settings so only trusted contacts can see your posts. And if you want to share holiday photos, do it once you’re back.

Organised groups often monitor open social profiles to identify empty homes. Don’t give them that opportunity.

8. Keep outdoor areas tidy

A neglected garden or terrace can also affect your home’s security. Tools, ladders or poorly placed furniture can be used to climb walls or access windows.

A well-kept exterior suggests the property is occupied and reduces temptation. Install motion-sensor lighting in key areas.

If you have outdoor cameras, make sure lights don’t interfere with visibility and that angles cover critical points.

9. Get to know your neighbours

It may sound simple, but it’s one of the most effective measures. In smaller communities or residential areas, attentive neighbours are a powerful security asset.

If you notice anything unusual or unfamiliar people nearby, report it. Likewise, you can ask neighbours to keep an eye on your home when you’re away.

Security is also built on trust and cooperation. No camera replaces a watchful neighbour.

10. Avoid careless habits

Home security depends as much on behaviour as it does on technology. Don’t leave spare keys under the doormat or mention trips on your voicemail.

Check doors and windows every night. If you employ domestic staff or maintenance workers, change locks or codes when they no longer need access.

A home security plan isn’t complicated—it’s about consistent, sensible routines.

Protecting your home doesn’t require huge spending or constant worry. Good home security is about anticipating risks, understanding weak points and combining smart habits with reliable technology.

Start with the essentials: a secure door, a connected alarm system and responsible day-to-day habits. If you also rely on a trusted service like Olin Protect, you’ll have peace of mind knowing your home—whether it’s your main residence or a second property—is always protected.

Looking after what matters most is much easier when you have solutions designed around you.
