Choose SimpliSafe for keypad control and more included entry coverage, or ADT Blu if you plan to add cameras. In this SimpliSafe vs ADT comparison, your daily routine and willingness to carry a service plan matter as much as the starter kit.

This comparison covers the SimpliSafe 8-Piece Wireless System and ADT Blu Starter Kit. It does not compare every package or installation service sold under either brand.

Start with the doors you need covered, who will respond to alerts and how everyone will arm the alarm. A kit fits when those choices work together.

SimpliSafe vs ADT Blu: what comes in each kit?

SimpliSafe includes more entry coverage and separate physical controls, while ADT Blu provides a smaller sensor bundle with camera expansion options. Count useful devices rather than comparing the total number of pieces.

The SimpliSafe package contains a Base Station, four entry sensors, one motion sensor, a wireless keypad and a panic button. Its entry sensors can protect doors, windows or cabinets.

ADT Blu includes a base hub, three door/window sensors and a pet-friendly motion sensor. A yard sign and four window stickers are also included, but they don't add detection coverage.

For a home with front and back doors plus two accessible windows, SimpliSafe's extra entry sensor has a clear use. If you need direct coverage on more openings, neither starter bundle alone fills that plan.

A motion sensor covers movement through a room rather than the opening of each door or window. It can complement entry sensors, but it doesn't replace them when you want to know which opening was triggered.

For help matching a bundle to your layout, read our guide to DIY home alarm systems. The broader home security kits guide can help if neither package covers your needs.

Who should buy SimpliSafe, and who should skip it?

Buy SimpliSafe if shared keypad access and door coverage are your priorities. It suits households that want a way to arm and disarm at home without making a phone the only everyday control.

A physical keypad is useful when household members leave at different times or prefer buttons to an app. Choose its location around your usual arrival route, where you can reach it without crossing a room unnecessarily.

The panic button also gives this package a distinct purpose for someone who wants a dedicated way to request help. Its police dispatch function and silent panic option require professional monitoring.

Skip this kit if you expect that dispatch feature to work without a subscription. SimpliSafe products and professional monitoring are also sold and supported only in the US, which rules it out for a home elsewhere.

If cameras are central to your purchase, choose around a confirmed camera-and-plan combination. The strongest reason to buy this particular SimpliSafe bundle is its included alarm equipment, rather than an assumed future camera setup.

SimpliSafe backs the system with a 1-year limited warranty. Buy through an authorized source, since SimpliSafe warns that unauthorized third-party purchases may void the warranty and other protections.

Who should buy ADT Blu, and who should skip it?

Buy ADT Blu if you want to start with an alarm and later add supported cameras or glass break sensors. It fits buyers who are comfortable using an app and keeping a service plan.

Its expansion options include indoor, outdoor and doorbell cameras. That helps if your plan has clear stages, such as protecting doors now and adding a view of the front entrance later.

Skip ADT Blu if your main requirement is avoiding an ongoing plan. Self-monitoring is available, but it still requires Self-Protect rather than removing the service requirement.

Also check your phone before ordering. ADT Blu specifies Apple iOS 17.0 or later, or Android 12 or later, so an older phone may affect your setup plans.

Don't choose this bundle simply because you recognize the ADT name and expect someone to install it. This is a DIY kit with guided setup, so plan to place and configure the equipment yourself.

ADT Blu provides a 90-day limited warranty on eligible equipment parts, starting from the order date, with terms and exclusions. Inspect the contents promptly so missing parts or setup problems don't sit unresolved.

Which system is easier to install?

Both support DIY installation, so preparation will do more for a smooth setup than choosing by a promised completion time. Decide where each device belongs before attaching it.

SimpliSafe's setup starts with plugging in the Base Station, downloading the app and placing the sensors. It requires no wiring or drilling, and SimpliSafe offers installation help if needed.

ADT Blu uses guided setup in the ADT+ app. Its entry sensors include adhesive strips and optional screw mounts, while its motion sensor uses a wall mount.

ADT Blu says most people can set it up in under an hour. Leave extra time for account setup, choosing positions and checking each device before treating installation as complete.

Before mounting entry sensors, check that the moving and fixed parts can align as the door or window opens and closes. Follow the manufacturer's spacing instructions rather than guessing from how close the pieces look.

Clean the mounting surface as directed and let it dry before applying adhesive. Loose paint, dirt or an uneven frame can make an otherwise suitable location a poor mounting spot.

Renters should check lease terms before drilling or attaching anything to painted surfaces. Adhesive avoids screw holes, but removal can still affect a finish.

Once positioned, use the system's recommended check procedure to confirm that every sensor reports correctly. Name devices by location, such as “back kitchen door,” so a later alert is easy to understand.

How do the apps and everyday controls compare?

SimpliSafe offers a keypad alongside its app, while ADT Blu centers this kit on ADT+ controls. Choose the approach that every regular user can follow.

The SimpliSafe app supports remote arming and disarming. Its wireless keypad needs no plug, and its backlit buttons light up for use and go dark afterward.

You can also arm SimpliSafe at home through Amazon Alexa or Google Assistant. That feature covers arming, so don't assume voice commands support every action available through the app or keypad.

ADT+ supports remote arming and disarming and sends real-time phone alerts when an entry sensor is triggered. Make phone notification permissions part of setup rather than assuming every alert will be visible.

Before relying on either system, agree on who arms it last and who checks unexpected alerts. A shared household needs a clear routine for late arrivals, visitors and someone leaving while others remain home.

For the steps between detection and response, read how a home security system works. It helps explain why a sensor alert and an emergency response are separate events.

What monitoring plan do you actually need?

Choose professional monitoring if you want a monitoring team involved when you can't respond; choose self-monitoring only if you can manage alerts yourself. The word “optional” needs careful reading because it can refer to professional service without meaning every feature is free.

SimpliSafe makes professional monitoring optional and offers it without a long-term contract. That service is required for panic button dispatch and Base Station network backup.

ADT Blu offers Self-Protect for self-monitoring and Pro-Protect for 24/7 professional monitoring. It lets you cancel or switch plans without a long-term contract, but a plan remains required for this system.

Self-monitoring fits someone who can notice an alert, assess it and decide what to do. If you often put your phone away during work, sleep through notifications or travel where reception is poor, build those gaps into your choice.

Professional monitoring doesn't remove your household's responsibilities. Keep contact details current and make sure everyone understands how to disarm the system and handle an accidental alarm.

What changes the SimpliSafe vs ADT monitoring decision?

Your response plan matters more than the plan's name. Write down what should happen when a sensor triggers while you're asleep, at work or away from home.

Then match those situations to the service you intend to use. For a closer look at the optional-service route, read whether SimpliSafe works without monitoring.

How should you plan coverage for pets and awkward rooms?

Plan around the shape and use of each room, rather than assuming one motion sensor covers an entire floor. Walls, doorways and furniture can divide a space into separate detection areas.

SimpliSafe specifies a 35-foot detection range and a 90-degree field of view, and describes its sensor as suitable for pets under 60 lb. It recommends corner placement for room coverage.

ADT Blu describes its motion sensor as pet friendly but provides no pet weight limit here. Don't carry SimpliSafe's weight guidance over to the ADT device.

Pet-friendly sensing still depends on following placement instructions. Consider raised furniture and the routes pets use, then check the setup with their normal movement in mind.

For an L-shaped room or a hallway around a corner, mark the area the sensor can face directly. Don't count a room as covered simply because the sensor is nearby.

Assign entry sensors to the openings you most want monitored. A cabinet sensor may serve a useful privacy purpose, but first decide whether a door or accessible window needs that device more.

What should you check before adding cameras?

ADT Blu offers a clear camera expansion route, but cameras require Video Connect. Confirm the service arrangement for your planned mix of alarm sensors and cameras before buying add-ons.

The starter kit contains no camera. Think of it as an alarm foundation rather than a complete system for viewing entrances or outdoor spaces.

Choose each camera location around a specific task, such as seeing who is at the front door. Adding devices without a purpose can leave you with more notifications rather than more useful information.

Before ordering, confirm device compatibility, placement needs and the required plan combination directly with ADT Blu. Don't assume that selecting Pro-Protect automatically settles every camera service requirement.

For either brand, map the system you want a year from now. A starter bundle is useful only if the equipment and services you intend to keep still fit that plan.

What care and setup mistakes should you avoid?

Keep sensors secure, power available and household routines current. Small changes around a device can matter even after a successful installation.

Check sensor alignment after door repairs, painting or moving furniture near a device. If adhesive starts lifting, follow the mounting instructions rather than leaving a sensor hanging loosely.

Respond to low-battery notices and use the specified replacement type. Our SimpliSafe battery replacement guide can help you plan that maintenance without guessing.

Keep the base's power connection accessible and avoid unplugging it for another appliance. SimpliSafe specifies up to 24 hours of Base Station battery backup, but backup power doesn't mean every service works without its required plan.

Don't confuse battery backup with network backup. One keeps equipment powered during an outage; the other addresses the communication path, and service requirements still matter.

Avoid placing sensors first and planning coverage afterward. Mark the openings and rooms on paper, then assign the included devices so you can spot gaps before mounting.

Revisit app access and contact details when someone moves out or changes phones. An alarm routine that suited the household at installation may need changes later.

Which DIY home security kit should you choose?

Choose SimpliSafe for a household that wants keypad access and useful entry coverage from the starter box. Choose ADT Blu when its camera expansion path fits a specific plan and you're comfortable with required service.

For SimpliSafe vs ADT Blu, use 3 final checks: count the openings you want covered, choose how everyone will control the alarm and decide who will respond when nobody is home. If one kit leaves a gap in those answers, resolve it before ordering.

Renters and smaller households can use our guide to alarm systems for apartments to refine placement and coverage. Buy the system whose daily routine you can follow consistently, with the service needed for the features you expect to use.

Frequently asked questions

Is SimpliSafe or ADT Blu better for a DIY setup?

SimpliSafe suits a no-drill setup with a separate keypad, while ADT Blu suits buyers who prefer guided installation through ADT+. Both support DIY installation, so the better choice depends on your mounting surfaces, phone compatibility and the controls your household will use each day.

Can you use SimpliSafe or ADT Blu without professional monitoring?

Both let you skip professional monitoring, but ADT Blu still requires a plan; its Self-Protect option supports self-monitoring, while Pro-Protect provides professional monitoring. SimpliSafe makes professional monitoring optional, though panic button dispatch and Base Station network backup require that service.

Which kit includes more entry sensors?

SimpliSafe includes four entry sensors, compared with three door/window sensors in the ADT Blu kit; that extra sensor matters if you have a fourth opening to cover immediately. Count the doors and accessible windows you want protected before deciding which starter bundle fits your home.

Can you add cameras to ADT Blu?

Yes, ADT Blu supports indoor, outdoor and doorbell camera add-ons, and cameras require Video Connect. The starter kit does not include a camera, so plan for both the extra equipment and its service requirement rather than treating this bundle as a complete camera system.

Which system is better for renters?

SimpliSafe is a good fit for renters who want installation without wiring or drilling; ADT Blu also offers adhesive mounting for entry sensors, with optional screws and a wall-mounted motion sensor. Check your lease, surface condition and mounting instructions before attaching equipment, since adhesive can still affect paint.
