The Arlo Home Security System is our Best Overall pick because one sensor does the work of several. Each 8-in-1 All-in-One Sensor detects motion, water leaks, temperature, door and window openings, and smoke/CO alarms. It suits renters and homeowners who want simple, wire-free coverage with no contract.
Keep reading about Arlo Home Security System
The system is recommended in 8 expert guides. Forbes Home gave it 4.3 out of 5, NerdWallet 4.5 out of 5, The Ambient 4.5 out of 5 and SafeWise 4 out of 5. Installation is wire-free DIY, and sensor battery life is up to 1 year.
Outage protection is a strength. The Keypad Sensor Hub has built-in motion detection and a backup battery of up to 12 hours, and cellular backup keeps protection on during power or internet outages. Smart home support covers Alexa, Google Home, Apple HomeKit and IFTTT, which is the widest list among the four systems here.
The trade-off
Live professional monitoring is a paid subscription, so budget for it if you want 24/7 response. Bundles include only 2-5 All-in-One Sensors depending on the one you pick, so check that the count matches your doors and rooms.
Cove DIY Home Security System: Also Great for Custom Setups
Best for: Buyers wanting a customizable system with flexible month-to-month monitoring
Cove offers a highly customizable system with guided setup, strong backup connectivity, and fast emergency dispatch. It suits buyers who want a flexible setup without a long-term contract.

Cove earns the Also Great spot because you can build the system around your home. The range includes door and window sensors, motion detectors, cameras and environmental sensors, and glass-break, flood, smoke and CO detectors are also available. It suits buyers who want a flexible setup with month-to-month monitoring.
Keep reading about Cove DIY Home Security System
Cove is recommended in 10 expert guides, the joint-highest count in this roundup. SafeHome.org scored it 8.8 out of 10 and Security.org 8.7 out of 10. A touchscreen guides the DIY setup, which the manufacturer says takes under 30 minutes.
Connectivity and backup are strong. The hub uses Ethernet with 4G LTE cellular backup and includes a 24-hour battery. Emergency dispatch is RapidSOS-enabled for fast contact with 911. There are no long-term contracts, and a 60-day money-back guarantee lets you try it with less risk.
The trade-off
Professional monitoring is required on all plans, so you can't run it as a self-monitored system. There are three monitoring tiers (Basic, Plus and Premium), and costs rise as you move up. Smart home support is limited to Alexa and Google Assistant, so Apple HomeKit users should look at Arlo.
Wyze Home Monitoring Core Starter Kit: Best Value for Starting Small
Best for: Budget shoppers starting small and expanding their system over time
Wyze is an affordable way to start a monitored security system, with easy installation and room to expand. Cancel-anytime monitoring keeps commitment low.

- Expandable up to 100 sensors as needs grow
- Noonlight-backed monitoring with roughly 30-second response time
- No contract; cancel anytime

The Wyze Home Monitoring Core Starter Kit is the Best Value pick and the only budget-tier option here. It suits shoppers who want a monitored system now and plan to add to it later. Installation is wireless and peel-and-stick, with no tools required.
Keep reading about Wyze Home Monitoring Core Starter Kit
The starter kit has three sensors: two entry sensors and one motion sensor. The system can expand to 100 sensors in total. Monitoring is 24/7 through Noonlight, with a roughly 30-second response time, and there is no contract, so you can cancel anytime. It's recommended in 7 expert guides, and U.S. News & World Report rated it 4.2 out of 5.
Other specs include a siren of 88 dB at 2 feet and indoor range of 500 feet (152 meters). The motion sensor detects up to 25 feet with a 120-degree field of view. Smart home support covers Alexa, Google Assistant and IFTTT.
The trade-off
The hub's rechargeable battery lasts 10 hours, the shortest backup of the four systems compared here. The starter kit includes only three sensors, so many buyers will want to add more. It's best for budget shoppers who want to start small and expand over time.
Ring Alarm Pro: Premium Pick for a Built-In Wi-Fi 6 Router
Best for: Ring ecosystem users wanting a security hub with built-in router
Ring Alarm Pro combines a security hub with a Wi-Fi 6 router and strong outage protection. It's best for those already invested in the Ring ecosystem or wanting Z-Wave flexibility.
- Range
- 250 feet to base station (Z-Wave), 1500 sq. ft. WiFi coverage
- Mobile app
- Ring app with iOS/Android support
- Backup battery
- Internal rechargeable Lithium Ion, up to 24 hours in Low Power Mode
- Contract required
- No contract required
- Installation type
- DIY, tabletop or wall mounted
- Number of sensors
- Expandable; base unit sold with additional sensors in kits
Reasons to buy
- Built-in eero Wi-Fi 6 router doubles as home networking
- Loud 104 dB siren
- 24-hour battery backup plus cellular backup internet
- Z-Wave support allows third-party sensor integration
Reasons to avoid
- Base unit needs additional sensor kits for full coverage
- Silent Security
- 8.4
- Smart Home Explorer
- 8.0
- The Tested Hub
- 9.2
- Android Police
- 8.0
Ring Alarm Pro is the Premium Pick because it combines a security hub with a built-in eero Wi-Fi 6 router. It suits people already invested in the Ring ecosystem, or anyone who wants Z-Wave support for third-party sensors. The router covers up to 1500 sq. ft. and supports speeds up to 900 Mbps.
Keep reading about Ring Alarm Pro
It is recommended in 10 expert guides. Silent Security scored it 8.4 out of 10, The Tested Hub 4.6 out of 5, and Smart Home Explorer and Android Police each 8 out of 10. The siren is a loud 104 Decibel siren measured at 1 ft.
Backup is a highlight. An internal rechargeable lithium-ion battery lasts up to 24 hours in Low Power Mode, and cellular backup internet keeps devices connected during outages. Z-Wave range to the base station is 250 feet. Installation is DIY, either tabletop or wall mounted, and no contract is required.
The trade-off
The base unit needs additional sensor kits for full coverage. Professional monitoring is an optional add-on through Ring Protect Pro. Alexa support is native, but the system is built around the Ring ecosystem, so it makes most sense if you already use Ring devices.

How to Choose the Best DIY Home Security System
Decide how much monitoring you want
Cove requires professional monitoring on every plan. Arlo and Ring offer paid professional monitoring, and Wyze's monitoring is backed by Noonlight. If you want a system that works without a subscription, check what each one does without monitoring before you buy.
Check outage protection
Burglars don't wait for your Wi-Fi to work. Cove and Ring list 24-hour hub backup, Arlo lists up to 12 hours on its Keypad Sensor Hub, and Wyze lists 10 hours. Arlo, Cove and Ring also add cellular backup. Wyze's facts don't mention cellular backup, so confirm it before you rely on it.
Count your entry points
Starter bundles are small. Arlo includes 2-5 sensors depending on the bundle, Wyze includes three, and Ring's base unit needs extra sensor kits. Count doors, windows and rooms before comparing bundle sizes.
Match your smart home platform
Arlo covers Alexa, Google Home, Apple HomeKit and IFTTT. Wyze covers Alexa, Google Assistant and IFTTT. Cove supports Alexa and Google Assistant. Ring is Alexa-native and works within the Ring ecosystem, with Z-Wave for third-party sensors.
Think about renting
Arlo's wire-free setup and Wyze's peel-and-stick installation need no hardwiring. Renters should check each product's installation notes before buying.
How We Picked These Systems
We compared DIY home security systems using manufacturer specs and independent expert recommendations. We looked at sensor coverage, backup power, connectivity, monitoring terms, contract requirements and smart home support. We also looked at how often independent buying guides recommend each product and at the scores reviewers published. We have not hands-on tested these systems. Specs come from manufacturer pages, and we describe each product on its own terms.
Bottom Line
For most homes, the Arlo Home Security System is the easiest recommendation: all-in-one sensors, wire-free setup, outage backup and broad smart home support. Choose Cove if you want to customize the system and don't mind monitoring being mandatory. Pick the Wyze Home Monitoring Core Starter Kit if budget matters most and you plan to expand. Go for Ring Alarm Pro if you already use Ring or want a hub with a built-in Wi-Fi 6 router.
