Using a home security system can give you excellent access control and safety, but it comes with a host of decisions to make. That includes which brand is best for you, as well as exactly which security kit is right for your home and which devices you should add to complete it. Both websites and professional installers can be pushy about recommending as many add-ons as possible -- how do you know if they're worth it?
I'm using my years of security reviews to go over the absolutely worst devices for your home, why they're either outclassed or no longer necessary and how you can save money by ditching them before you click the buy button.Â

Alarm touchscreens
Touchscreens look great, but they don't need to be part of your security system.
In years past, a fancy, colorful touchscreen on the wall was the mark of a highly advanced security system with all the bells and whistles. Not so today. With app-based controls, those touchscreens have become less and less convenient, eventually taking up space without reason and increasing the cost of the system.
Today, your phone and a simple keypad on the security system hub are usually all you need. Unless you are desperate for another keypad option near the entryway, consider cutting out the touchscreen and lowering your prices.
Temperature sensors and smoke detectors
Your home probably already has enough smoke detectors.
There's nothing wrong with temperature sensors or smoke detectors. They're very important parts of the smart home. In fact, they're so important you almost certainly already have them. Smoke detectors are already required by law in certain parts of your home (depending on your state or country). Thermostats, especially smart thermostats with satellite sensors, already do a great job of detecting temperatures throughout your home.
Home security brands may try to upsell you their own temperature or smoke sensor to place in the kitchen or by the fireplace, etc. If your home isn't so huge that smoke detectors are far away from these spots, you can probably skip these. Or look for devices that can listen for sirens from existing detectors to give you remote notifications as a bonus.
Motion sensors
Motion sensors aren't usually as reliable or useful as access sensors.
Motion detectors are a common sensor in home security systems, a mainstay for years that can detect motion in specific rooms or areas and trigger alarms. But I don't think they're necessary for two reasons.
First, motion detectors just aren't as useful as access sensors, like open/close sensors that can tell you if a door, drawer, safe or window is opened and sound alarms accordingly. Vibration sensors, which can detect breaking glass or attempts to break in as well as tampering, can also serve a vital role with highly targeted applications. With those two sensors, there's not a lot left for motion sensors to do.
Second, motion sensors just aren't as reliable as the devices I mentioned. They can be finicky, often too sensitive or too dull even after adjustments, and then need to be in the exact right places. Even modern sensors may also be triggered by large or wall-bouncing pets, so dog-friendly homes may have to turn them off when a four-legged friend is around.
If possible, skip or reduce motion sensors to save money, or purchase them separately from your security system.
Panic buttons
Panic buttons may give peace of mind, but they're rarely necessary these days.
Panic buttons sound like a good idea, whether they're carried fob-style or installed on a wall in a convenient location. But I'm also putting these in the "unnecessary" category, since today we all have SOS and emergency button settings on our smartphones that we can use anywhere, at any time. Or in a pinch, you could ask a smart speaker to call emergency services.
Proprietary smart locks
Smart locks are an excellent home addition, but be wary getting limited models.
Far from having a problem with smart locks, I think everyone should get one as long as they don't mind occasionally replacing batteries. But be wary of smart locks created specifically by a home security company that don't work well apart from it. Often, these proprietary smart locks suffer from awkward designs, missing features and poor functionality.
Instead, look for a security system that supports third-party smart locks, which are usually superior. ADT, for example, offers useful support for Yale smart locks, and other brands support a variety of third-party lockmakers. You could also get a smart lock separate from your security system and not worry about connecting it.
This holds true for many smart home add-ons that security systems may offer. Always go for systems that support the latest third-party devices, rather than just offering proprietary models.
What home security features are most worth it?
Entry and access sensors are one of the most useful parts of a security system.
Today's security systems offer plenty of useful add-ons and settings that I've appreciated when testing and securing my home. Access and vibration sensors are always handy when they're set up to detect opened doors or breaking glass. A compatible security camera is also a great addition, especially if it has two-way audio, so you can immediately check on a situation if your alarm goes off. An integration with a good third-party smart lock that has lots of support is also welcome.
