Security systems for a home or apartment give peace of mind about loved ones and belongings. Some systems cross over into two categories, such as wireless self-monitored setups, but figuring out what security system you need for your home isn't always clear. So, if you're thinking of installing a new security system in your home or apartment, check out the six most common security systems before making a purchase.

1. Monitored Security Systems

The security systems in this group are either professionally monitored or self-monitoring. Professionally monitored systems are continuously overseen by dedicated teams. If an unusual event triggers your alarms, a representative will contact you to verify what's happening, then call the authorities on your behalf if necessary.

Self-monitoring systems give authorized users access to live camera feeds and other details that could indicate issues. However, it's up to them to analyze the data and decide whether to call the police.

2. Unmonitored Security Systems

A fully unmonitored system may capture camera footage or include door and window sensors. However, notifying the authorities or getting alerted to a potential issue does not happen unless someone hears the alarm and acts accordingly.

Most security systems on the market now connect to apps. However, if you move into a home with an older alarm, it's likely the truly unmonitored type. Those usually work by emitting noises loud enough to scare a burglar and help neighbors notice potential issues.

3. Wired Security Systems

These security systems have hard-wired connections to get power and send signals to a central hub. Wires connect every sensor and entry point in the home. Of course, professionals must install them for you, but that process could be easier than expected, particularly if your house came prewired for such setups.

Unlike many wireless systems, wired options run on electricity rather than batteries. However, they typically have battery backups that keep operating during power outages.

Also, if you rent your home and want a wired security system, check your lease agreement or ask your landlord first. Just as a commercial lease clarifies how much the tenant pays and what that amount covers, a residential lease will say whether you can modify your rental unit during the tenancy.

Finding that out is crucial if you rent your home and think a wired system is the right choice. That's because installations involve drilling holes and putting wires behind drywall.

4. Wireless Security Systems

These options trade wires for radio waves to send data and notifications of possible problems. Renters and people who move often appreciate the portability of wireless systems. However, their main downside is that electromagnetic interference from other devices in the vicinity could cause the setup to show unwanted behavior by triggering a false alarm.

Compared to wired options, these systems also provide more flexibility for capturing different parts of your home as needed. For example, perhaps you want to have a camera in the basement, but only for supervision purposes when your child and their friends play down there. Wireless systems simplify those short-term needs.

5. App-Based Security Systems

Most modern security systems come with apps, letting users check statuses, watch live camera feeds, and get real-time notifications of certain events.

However, you'll also less commonly find security apps not associated with a particular model or brand. They aim to protect a person rather than property, though. For example, the apps usually work with your phone's location-tracking capabilities and allow choosing a group of people who can see where you are and intervene if necessary.

For example, Be Closer is an Android app to help family members keep track of each other with permission. It could put parents at ease when their first-year college student goes out on weekends, for example.

Alternatively, Silent Beacon combines a Bluetooth device with a mobile app. This system pairs with Bluetooth 4.0-enabled devices, such as smartphones, fitness trackers, and laptops. Users can then use a one-touch method to call 911 or any other number. Silent Beacon also allows sending text messages, emails, and push notifications with your location details to selected people. A "nudge" feature lets you verify your well-being, too.

These options do not primarily protect homes, but you could easily use them for that purpose. Imagine coming home to a possible intruder after recently moving to a new place. The solutions here let someone send help, even without knowing your address.

The Silent Beacon also doubles as a small-item tracker. Losing your house keys is a security issue, but Bluetooth technology helps you find them.

6. DIY Security Systems

Perhaps you'd prefer to create a security system yourself. These options are nowhere near as robust as the possibilities already discussed, but they work in a pinch and may not require buying anything new.

For example, did you know a heavy-duty stick in the track of your sliding door stops someone from forcing it open? You can also make several minor but effective modifications, such as reinforcing the kickplate at the bottom of the door, making it harder for a criminal to get inside the home.

You can also use uncommon or tamper-resistant bolts to latch your shed door shut.

Additionally, it's easier than you might think to make a door alert system from a smoke detector. Numerous websites sell inexpensive, basic options requiring minimal or no setup time if you prefer less legwork.

Safer Home, Happier Residents

Your home is ideally a place where you feel at ease and love spending time. However, that likely won't happen if you feel unsafe or worry about break-ins. Use this overview to make informed decisions about which security systems are best for your needs.

It's also a good idea to stay abreast of the latest options in security systems so you can upgrade or make additions as necessary. That way, you'll always feel safe and secure.
