Moving into a new home usually comes with a long list of things to organise. There are boxes to unpack, utilities to arrange, furniture to assemble, and countless small details that are easy to overlook.

Security should be part of that first-week checklist.

A new home may have locks, alarms, cameras, or other security equipment already installed, but that doesn't necessarily mean everything is configured for the new occupants. Previous owners, tenants, contractors, or family members may have had access to keys, codes, or connected devices.

Taking some time to review the property from scratch can prevent many unnecessary problems later.

1. Check Every Exterior Door

Start with the doors.

Test the main entrance, back door, side entrance, garage door, and any other exterior access point. Make sure each door closes properly and that the locks work smoothly.

If you have moved into a previously occupied property, consider whether old keys may still be circulating.

It's also worth checking the condition of door frames, hinges, handles, and other hardware. A lock is only one part of an entrance.

2. Inspect the Windows

Windows are easy to forget because they aren't normally used as entrances.

Walk through the property and check that accessible windows close securely. Pay particular attention to ground-floor windows, basement windows, balcony doors, and windows hidden from public view.

If the home has window locks or sensors, test them rather than assuming they work.

This is also a good opportunity to identify windows that may need better lighting or visibility from outside.

3. Change Existing Access Codes

If the property has a digital lock, alarm, garage system, or other access-controlled equipment, find out whether existing codes can be changed.

Never assume that an old PIN is known only to you.

Create new credentials for the people who currently need access and remove unnecessary users where the system allows it.

The same principle applies to physical access cards and digital credentials.

4. Find Out What Security Equipment Already Exists

Some homes come with equipment that new owners don't immediately notice.

Look for:

Security cameras
Doorbell cameras
Motion sensors
Door and window sensors
Alarm panels
Smart locks
Outdoor lighting controls
Garage controllers

Identify what each device does and whether it is still connected.

A camera mounted on the wall is not particularly useful if nobody knows which application controls it or whether it is still connected to the network.

5. Review the Home Network

Connected security equipment depends heavily on the home's network.

Change the router's default password if necessary and use a strong Wi-Fi password. Review connected devices and remove equipment that no longer belongs in the home.

If you inherit smart-home equipment from a previous resident, check whether it is connected to an old account before relying on it.

Keeping a simple record of important connected devices can make future troubleshooting much easier.

6. Decide Where Monitoring Would Actually Help

Not every part of a home needs a camera or sensor.

Instead, identify areas where additional information would be useful.

For example, you might want visibility around:

The main entrance
Driveway
Garage
Backyard
Side gate
Ground-floor windows

The goal is to cover meaningful areas rather than filling the property with unnecessary equipment.

7. Consider Connected Security as a Layer

Once the basic physical security of the property has been checked, technology can provide additional visibility.

Modern Smart Home Security Systems can combine devices such as cameras, sensors, alarms, and access-control equipment so that homeowners can receive information about activity around the property.

This can be especially useful when the home is empty.

For example, a door sensor might indicate that an entrance has opened while a camera provides additional context. Instead of relying on one device, different sources of information can work together.

8. Test Everything Before You Need It

One of the easiest mistakes is assuming that a security device works simply because it is installed.

Test the equipment.

Open a protected door and check whether the expected notification appears. Walk through an area covered by a motion sensor. Check camera views during both daytime and nighttime conditions.

If the system includes remote access, test it while you're still at home.

Finding a problem during a test is much better than discovering it after an important alert has been missed.

9. Check the Exterior at Night

A property can look completely different after sunset.

Walk around the outside of the home when it is dark and look for areas that are difficult to see.

Pay attention to:

Side entrances
Garage areas
Driveways
Garden paths
Back doors
Areas hidden by plants or walls

Outdoor lighting can improve visibility, while motion-activated lights may provide additional awareness when someone approaches.

10. Be Careful With Shared Access

Family members, domestic workers, maintenance staff, neighbours, and service providers may sometimes need access to a property.

Rather than sharing one permanent password or key with everyone, use individual accounts or temporary access methods when the technology supports them.

That makes it easier to know who has access and to remove permissions when they are no longer necessary.

11. Keep Emergency Information Somewhere Accessible

Security isn't only about preventing unwanted access.

New homeowners should also know how to respond if something goes wrong.

Keep important contact information available, such as building security, property management, trusted neighbours, emergency services, and relevant maintenance contacts.

If the home has an alarm system, understand what the different alerts mean and what steps should be taken after one occurs.

12. Create a Maintenance Routine

Security equipment should not be installed and forgotten.

Set aside some time every few months to check:

Camera positioning
Batteries
Door and window sensors
Smart-lock operation
Software updates
Network connectivity
Notification settings
User permissions

A small maintenance routine can prevent equipment from quietly becoming unreliable.

A Simple First-Week Security Checklist

For new homeowners, the process can be simplified into a short checklist:

Check every exterior door.
Inspect accessible windows.
Change old access codes.
Review existing keys and access cards.
Identify installed security equipment.
Secure the home Wi-Fi network.
Test cameras and sensors.
Check outdoor lighting.
Review who has digital access.
Save important emergency contacts.
Create a recurring maintenance reminder.

You don't have to complete every improvement on the first day. The important thing is to understand the property's current security situation and work through the gaps systematically.

Final Thoughts

Moving into a new home is an opportunity to start with a clean security setup.

Check the physical entrances first, review old access credentials, understand existing equipment, secure the network, and test everything before depending on it.

Technology can provide another layer of awareness, but it works best when combined with sensible physical security and regular maintenance.

A simple checklist may take less than an hour to create, but it can make the rest of your time in the new home much easier to manage.
