1. Inform a Trusted Neighbor: Let a trusted neighbor know that you'll be away. They can keep an eye on your apartment, collect mail, and report any suspicious activity.

2. Install Smart Security Devices: Consider installing smart security devices such as cameras, doorbell cameras, and smart locks. These allow you to monitor your apartment remotely and receive alerts if there's any unusual activity.

3. Upgrade Locks and Bolts: Ensure that all locks on doors and windows are secure. Consider upgrading to deadbolts or smart locks for added security.

4. Set Timers for Lights: Use timers to turn lights on and off at different times throughout the day. This creates the illusion that someone is home, deterring potential burglars.

5. Secure Sliding Doors and Windows: Place a metal or wooden rod in the track of sliding doors and windows to prevent them from being forced open.

6. Don't Advertise Your Absence: Avoid posting about your vacation on social media until after you've returned. Broadcasting your absence can make your apartment a target for burglars.

7. Stop Mail and Newspaper Deliveries: Contact the post office and newspaper delivery service to temporarily stop deliveries while you're away. A buildup of mail and newspapers is a clear sign that no one is home.

8. Consider a Home Security System: If you don't already have one, consider investing in a home security system. Many companies offer affordable options with 24/7 monitoring.

9. Secure Valuables: Store valuables such as jewelry, electronics, and important documents in a locked safe or a hidden location.

10. Ask for Police Patrols: Some police departments offer vacation patrol services where officers will periodically check on your apartment while you're away. Contact your local police department to see if this service is available.
