Arlo Home Security System SS1501 Review: DIY With Catches

If you want a home security system you can set up yourself without drilling into walls or paying an installer, this arlo home security system (ss1501, 5 sensors) review is for you. The SS1501 bundles a plug-in Keypad Sensor Hub with five All-in-One Sensors. It is built for people who want one kit to cover doors, windows, rooms and even water leaks, and it sits in the mid-range part of the market. It is aimed at renters and homeowners who want flexible DIY coverage, particularly anyone who already uses Arlo cameras.

This review is based on Arlo's published specs and on what independent expert reviews report, not on hands-on testing by us.

What you get in the box

The kit centres on a wired Keypad Sensor Hub. It plugs in, has a built-in siren and a built-in motion sensor, and works as the keypad you use to arm and disarm the system. Around it are five All-in-One Sensors, with magnets and adhesive for each one, plus flat and corner wall plates with screw kits (two of each) in case you would rather screw things down than stick them.

Arlo also includes a yard sign, two window decals and a quick reference guide. The signage is a small extra, but it adds a visible deterrent without anything more to buy.

Design and build: small sensors, flexible placement

Each sensor measures 1.1 x 0.57 x 2.38 in (27.95 x 14.55 x 60.69 mm) and weighs 24g / 0.05 lb. That is a compact footprint, and it suits a kit meant to go on door frames, window frames, walls or, as Arlo puts it, any flat surface. The kit includes adhesive, magnets and wall plates with screw kits, so you have more than one way to mount the sensors depending on the surface.

Two limits matter for placement:

• Indoor use only. The sensors are rated for 0° F to 113° F (0° C to 45° C), so this kit doesn't cover a shed, porch or garage that sees weather extremes.
• Motion range. The motion sensing is adjustable up to 20ft. when mounted at a 6ft. height. Treat that as a guide for room-sized spaces rather than a large open-plan area.

Each sensor runs on one CR2477 coin cell, which Arlo lists at 1 year. A battery you replace roughly yearly is a normal trade-off for a wire-free sensor, so it's worth setting a reminder.

Setup: no hardwiring, guided by the app

The selling point reviewers return to is installation. The kit is designed for DIY with no hardwiring, and the Arlo Secure app guides you through it. The hub plugs into power, the sensors attach to surfaces, and the app walks you through pairing and placement.

The sensors connect to the hub using SecureLink, which Arlo describes as providing longer range and a more secure connection. That matters in a larger home where sensors may be a few rooms from the hub. It is still wise to plan placement with range in mind rather than assume every corner will connect.

Features and what they mean day to day

Eight detection functions per sensor

This is the headline feature. Each All-in-One Sensor handles eight functions: motion, open/close, water leak, freeze, tilt, ambient light, smoke alarm listening and CO alarm listening. In practice, one sensor type can do different jobs:

• On a door or window, it works as an open/close contact.
• In a hallway or living room, it works as a motion detector.
• Near a washing machine or water heater, it can watch for leaks.
• In a cold space, it can flag freezing temperatures.
• Near an existing smoke or CO alarm, it can listen for that alarm to sound.

Because the hardware is identical, you aren't locked into buying specific sensor types and can rearrange the kit as your needs change. The catch is that smoke and CO alarm listening is not part of the free feature set. It requires a paid Arlo plan with Professional Monitoring after the trial.

Arming modes

The system offers three arming modes: Arm Away, Arm Home and Standby. They cover the basic scenarios of leaving the house, being home, and turning things off. Reviewers note that these are fixed, and a common criticism is that you can't build custom modes. If you want a more tailored setup, such as different zones armed at different times, this is a limitation.

Emergency response and monitoring

One Tap Emergency Response lets you contact fire, police or medical services from the hub or the app. Optional 24/7 Professional Monitoring is available with no contract. Both depend on a paid plan after the trial, which is the main thing to understand before buying. Reviewers also point out that cellular backup and professional monitoring cost extra and that the plan tiers can be confusing, so check exactly what each tier includes before you commit.

Works with Arlo cameras, but doesn't need them

The system works with Arlo cameras and video doorbells in the same app, but it doesn't require them. That makes it a sensible fit for two groups: people who already have Arlo cameras and want to add sensors, and people who want a sensor-first system and may add cameras later. If you want to mix in devices from other brands, note that reviewers report no third-party device support.

Performance, battery and connectivity

There is no benchmark to quote for a kit like this. What matters is how the specs line up with how you will use it.

• Coverage: Five sensors with eight functions each, plus a hub with its own motion sensing, gives the kit a lot of flexibility. The hub's six sensing functions in one unit add to that.
• Connectivity: SecureLink is Arlo's answer to range and security between sensors and hub. The hub is wired to power rather than battery-run, so it needs a nearby outlet.
• Battery: A coin cell per sensor at about a year is manageable, but with five sensors you'll want to replace them around the same time.
• Deterrence: The hub's built-in siren gives an audible alert without needing a separate siren accessory.

What experts like and what they criticise

The kit earns solid but not glowing marks. It averages 8/10 across 2 expert reviews, with Tom's Guide giving it 4 out of 5 and SafeWise also giving it 4 out of 5.

Reviewers praise the versatility of the sensors, the DIY setup that needs no hardwiring, the keypad hub with a built-in siren and motion sensor, the optional no-contract professional monitoring, and the ability to work with Arlo cameras without needing them.

A common criticism is the cost structure. Smoke/CO alarm listening and Emergency Response need a paid plan after the trial, and cellular backup and professional monitoring cost extra, with tiers that can be confusing. Reviewers also mention that there are only three fixed arming modes, that the app menus can be confusing, that there is no third-party device support, and that the sensors are indoor-use only.

Who should buy it

This kit makes sense if you:

• Want to install a security system yourself, with no hardwiring.
• Rent, or may move, and prefer adhesive mounting with the option of screws.
• Already own Arlo cameras or a video doorbell and want everything in one app.
• Like the idea of one sensor that can be a door contact, motion detector or leak sensor.
• Are happy to pay for monitoring in return for 24/7 professional help with no contract.

Who should skip it

Look elsewhere if you:

• Want the full feature set without a subscription, since several key features depend on a paid plan.
• Need integration with third-party smart home devices.
• Want custom arming modes beyond Arm Away, Arm Home and Standby.
• Need to protect outdoor spaces, since the sensors are for indoor use only.
• Prefer a simple, transparent pricing structure, given reviewers' comments about confusing tiers.

How it fits in the DIY security category

DIY security kits generally compete on ease of setup, sensor flexibility, monitoring options and ecosystem fit. The SS1501 does well on the first two and offers optional contract-free monitoring. Its ecosystem story is strongest for people already in the Arlo camp, and weaker for anyone who wants to mix brands. Your decision will likely come down to whether you are comfortable with the subscription structure and the closed ecosystem.

Verdict: a flexible kit, with the subscription fine print to read first

The Arlo SS1501 is a practical, easy-to-install starter system. The eight-function sensors, plug-in keypad hub with built-in siren and the camera-optional design give it real flexibility, and expert scores of 4 out of 5 from both Tom's Guide and SafeWise suggest it delivers. The compromises are equally clear: important features sit behind a paid plan, the arming modes are fixed, and there's no third-party support. If those don't bother you, it is a strong DIY option, especially for existing Arlo users. If they do, keep looking.
