For women living alone, security measures should not be limited to simply installing security equipment, but should begin at the stage of selecting a property. This article recognizes the security needs unique to women and introduces practical measures.

Security Risks Faced by Women Living Alone

While security in rental housing is important for all residents, women living alone face unique risks. According to statistics from the National Police Agency, reports of residential break-ins and illegal entry are increasing year by year, and crimes targeting women in particular—such as stalking, voyeurism, and groping—have become social issues.

The main security risks that women should be concerned about are as follows.

Illegal Entry and Burglary: To prevent break-ins targeting women living alone, multi-layered locking mechanisms and security windows are effective.

Stalking and Ambushes: There is a risk that your home's location can be identified through social media or that you may be followed on your way home. There are also cases where landlords or property management companies inadvertently leak room numbers or resident information, so advance confirmation is important.

Wiretapping and Voyeurism: Commercially available small listening devices and hidden cameras can be easily obtained online. They may be placed near balconies, windows, or around outdoor air conditioning units, so it's worth regularly checking and considering installing security cameras.

Fraud and Robbery by Visitors: Once someone knows you live alone, scammers and suspicious persons may visit. Pre-screening via door peephole or door camera is essential.

Five Security Points to Verify First When Choosing a Property

Before deciding on a property, here are five security points to verify.

1. Approach from Entrance to Public Road

Check if there are street lights or pedestrian traffic in front of your entrance and whether there are many blind spots. It's important not only to visit during the daytime, but to actually visit at night to check the brightness of street lights and the atmosphere of the surrounding area. Also check whether there are vacant properties or abandoned buildings nearby, and whether there are pedestrians or street cameras at night.

2. Building Entrance and Common Areas

Check for auto-lock, the presence of security cameras, and the building manager's work schedule. Verify that street lights around the entrance are sufficient, there are no blind spots, and delivery boxes are safely designed. Even older buildings often have had their security recently upgraded, so verification is important.

3. Window Structure and Security

Check whether the glass is single-pane or multi-pane, and whether the window frame has more than one lock. Especially for first-floor windows and waist-high windows, which experience high rates of break-ins, check for the presence of security glass (laminated glass). Security glass is difficult to break and makes noise even if it does break, which deters intruders.

4. Landlord and Property Manager Response

Confirm in advance to what extent resident personal information (room number, name, contact information) will be disclosed to outside parties. Whether mail is piled up in common areas or whether the property is kept clean is also an indicator of security awareness. It's also important to tell them that you are a woman living alone and to sense whether they will cooperate with security measures.

5. Balcony and Exterior Wall

Check whether the balcony is too close to an adjacent building and whether exterior wall ducts can be locked. Also check whether the outdoor air conditioning unit and meter box have access controls to prevent hidden cameras or listening devices from being installed.

How to Choose Add-On Security Equipment

Even if a property is not perfect, it is often possible to address any security gaps with add-on security equipment. Below, we introduce representative products and selection points.

Smart Locks

Smart locks provided by manufacturers such as Panasonic, Samsung, and Aqara are devices that complement or replace traditional keys. The advantages of smart locks are as follows.

  • •Eliminates the need to hand over duplicate keys, reducing the risk of key theft
  • •Allows you to check the lock/unlock status on your smartphone, reducing the anxiety of forgetting to lock the door
  • •Records the entry and exit history of visitors, making it easier to detect signs of intrusion
  • •Many add-on models for rental properties can be restored to their original condition

When selecting, confirm whether it's a type that attaches with double-sided tape or silicone adhesive or a type that partially replaces an existing key, and verify that it can be easily removed when you move out.

Security Glass (Film)

By applying security film to already-installed windows, the glass itself becomes more difficult to break. Products that enhance security performance while maintaining transparency (such as 3M Crystalline) are also commercially available, and can be installed either by hiring a contractor or through DIY. It is particularly effective for first-floor windows and windows that are easily accessible from balconies.

Door Cameras and Video Intercoms

Panasonic's door cameras and smart video intercoms allow you to visually confirm visitors and respond by voice. Models with motion sensors can detect and record suspicious behavior such as attempted break-ins.

Security Cameras and Recording Devices

Installing security cameras around balconies or entrances (with landlord permission) greatly increases deterrence against intruders. Video can be saved to cloud storage or local NVR (network video recorder) and used as evidence if needed.

Keyhole Covers and Supplementary Locks

Covering existing keyholes or installing supplementary chain locks or sliding chains also serves as a security measure. Many of these products can be restored to their original condition in rental properties and are cost-effective.

Negotiation Techniques with Landlords and Property Managers, and Restoration to Original Condition

When installing security equipment, cooperation with landlords and property managers is essential. Here are some tips for negotiation.

Consult About Security Measures in Advance

If you are considering installing a smart lock or security film, consult with your landlord or property manager in advance. By politely explaining that this leads to long-term occupancy through improved security and that restoration to original condition is possible upon move-out, most landlords will be cooperative.

Choose Restorable Products

Installing equipment in rental properties incurs the obligation to restore to original condition, so returning to the original state upon move-out is a prerequisite. For smart locks, choose models that can be easily removed after installation; for security films, confirm in advance with the contractor whether removal is possible; for door cameras, consider using non-damaging adhesive tape (such as 3M Command).

Offer a Bulk Response by the Property Management Company

In an era when many women seek security measures, if there is demand from multiple residents, the property management company may introduce security cameras or smart locks in common areas. By exchanging information between residents and making requests as a group, the likelihood of implementation increases.

Daily Behavioral Security Measures

In addition to equipment investment, daily behavioral habits are also important. Make the following measures a habit.

Social Media and Location Information Management

When posting photos of your home's surroundings or your plans to leave on Instagram, X (formerly Twitter), TikTok, and other platforms, check that location tags or metadata are not included. Also periodically check Google Maps' "Timeline" and "Location History," and monitor whether any unintended records remain.

Responding to Visitors and Opening the Door

When strangers visit, the basic rule is to verify them via door peephole or door camera before responding. Even for delivery services, confirm identification and company name, and respond calmly even if rushed. Avoid responding in ways that make it clear you're a woman living alone (such as your tone of voice), and creating the impression that multiple adults are present is also effective.

Upon Arriving Home and Leaving

When arriving home, check for suspicious persons nearby before opening the door, and it's effective to create a checklist to avoid forgetting to lock the door. When going out, it's known that leaving lights or TV on or making it appear someone is home are common practices. However, considering electricity costs and fire risk, using a timer outlet is safer.

Using Security Apps

Sharing women's security apps (such as GPS location sharing and emergency notification features) with friends or family enables quick response in emergencies. Making a habit of notifying close friends of your arrival time also helps raise security awareness.

Properties Near Stations and High Foot Traffic

Properties near stations have the advantage of more pedestrian traffic on the way home and shorter time spent walking dark streets, both beneficial for security. While rent tends to be higher, it's worth considering as a long-term safety investment.

Conclusion

Security measures for women living alone require a multi-layered approach, from property selection to daily behavioral habits. While there may be no perfect property, a combination of security equipment and behavioral habits can create a safe and comfortable life living alone. Using this article as a reference, build security measures tailored to your own lifestyle and budget.
