Our Picks at a Glance
How To Choose The Best DIY Home Security System
Choosing a self-install security kit means deciding how many doors and windows you need to cover, if you want cameras or just sensors, and if you are willing to pay a monthly fee for professional monitoring. Here is what matters most.
Sensor Count and Expandability
The number of entry sensors (the little magnetic pieces that stick to doors and windows) determines how many access points you can protect. A 7-piece kit is fine for an apartment, while a 24-piece kit may make more sense for a house with multiple exterior doors and a garage. Also check whether the system lets you add extra sensors later — most do, but the total limit varies.
Self-Monitoring vs. Professional Monitoring
Self-monitoring means you get app alerts and decide what to do. It is free after you buy the hardware. Professional monitoring costs a monthly fee — someone watches your system 24/7 and calls the police for you. Some systems offer it optionally with no long-term contract.
Video Quality and Night Vision
If you want cameras, look at the resolution. 1080p HD is clear enough to read a license plate during the day. 4K Ultra HD is noticeably sharper. Color night vision, which uses built-in spotlights instead of black-and-white infrared, makes it much easier to identify a person at night.
Backup Power and Connectivity
A hardwired system is useless during a power outage unless it has a built-in battery backup. Some systems also use 4G cellular as a backup internet connection, so alerts still reach your phone even if the Wi-Fi is down.

In‑Depth Reviews
1. SimpliSafe 7 Piece Wireless Outdoor Camera Home Security System
Our pick — over 4★ from 100+ verified ratings; the strongest balance of quality and price.
Seven pieces, one simple app, and a free month of professional monitoring right from the start.
You get two Outdoor Camera Series 2 units, a base station, a keypad, two entry sensors, and a key fob. The cameras capture a 140-degree field of view in 1080p HD and switch to color night vision using a built-in spotlight. The app lets you arm, disarm, and check live feeds from anywhere. If you want a professional monitoring plan, the first month is free with no contract required — the system keeps working even if you never pay a cent for monitoring.
What wins people over is the sheer ease of setup. Buyers report it is “simple to install” and that the “camera battery life is decent, especially with adjusted motion sensitivity.” The system weighs 5 pounds and measures 12.3 x 12.38 x 4.4 inches, so the box is substantial but the installation itself is wireless. The crowd favorite — 4.3 stars across hundreds of owners — confirms this is the most balanced pick between video coverage and optional pro response. Compared to the tolviviov kits below, this one gives you real outdoor cameras, not just door sensors.
One honest trade-off is that the included camera magnets reportedly weaken over time for some owners, causing the cameras to slip out of place. A few buyers found they needed to rethink the mounting approach after a week or two. If you want truly zero-touch outdoor mounting, this is the best all-rounder — just double-check that the magnetic mount works with your surface material.
Easy wireless setup
- Out-of-box simplicity with clear instructions
- 140-degree 1080p color night vision cameras
- Free first month of professional monitoring with no contract
Limited camera range
- Camera magnet mount can weaken after a week for some
- Heavier than most sensor-only kits at 5 pounds total
best for: Anyone who wants a proven, expandable system with the option of professional police dispatch, no long-term contract, and real outdoor camera coverage.
think twice if: You need a bare-bones sensor pack with no cameras — the 6-piece version below is the cheaper, camera-light alternative.
2. tolviviov WiFi Home Security System, 10-Piece Wireless Alarm Kit
A full ten-piece kit with zero monthly fees and a siren that hits 120 decibels.
For the price, this tolviviov kit packs a serious punch. It includes a Wi-Fi base station, five door sensors, two motion detectors, and two remote controls. The 120dB siren is loud enough to wake the whole street. It runs on an 8-hour backup battery, so it keeps working even when the power goes out. The app sends instant push alerts when a door or window is opened, and it works with Alexa for voice control.
The thing everyone raves about is how fast the setup is — most owners have it running within an hour. The system supports expansion up to 20 sensors and 5 remote controls. There is no monthly subscription at all, which makes this a true buy-once, own-forever solution. Buyers describe it as a “reliable, easy-to-set-up wireless system” with fast app notifications and a loud, deterrent alarm.
The main downside some owners trip over is that the app notifications can be tricky on a second phone, and a few found the alarm volume “pitiful” rather than loud. Note that the siren here is built into the base station, not a separate unit you can place in another room. Reach for this if you want the absolute best value in a sensor-only system that leaves no money on the table for monthly fees.
Affordable complete kit: An absurd amount of hardware for the money — five door sensors and two motion detectors cover an entire apartment or small house, all with no subscription.
App reliability issues: No built-in camera, so this stops intruders with noise and app alerts only; add a Wi-Fi camera separately if you need video evidence.
3. LWOHSI Wireless Alarm System with HD Security Camera
A slim, lightweight hub that brings both Wi-Fi and cellular backup to a single security camera system.
Unlike most sensor-only kits, this LWOHSI system ships with an HD security camera built into the ecosystem. The hub itself measures 7.09 x 0.59 x 3.86 inches and weighs just 1.5 pounds, so it is far more compact than the SimpliSafe 7-piece (which is 12.3 x 4.4 inches and 5 pounds). It connects via 2.4GHz Wi-Fi and also accepts a 4G SIM card for SMS alerts and voice monitoring — so if your internet goes down, the system can still call your phone. It supports up to 99 wireless sensors and 3 wired zones, making it the most expandable option here.
Setup is straightforward, though it does require a little more attention than the tolviviov kits. Owners note that it takes “a bit of setup to get it working” but praise the customer support: one buyer had a faulty controller replaced in three days. The system works with Alexa, Google Assistant, and the Tuya app, so you can arm or disarm with your voice.
The catch is that the system does not support 5GHz Wi-Fi — you need a 2.4GHz network. A few owners found the main siren “hallow and like a toy.” If you want a system that can still phone home when the Wi-Fi is down and supports an enormous number of sensors, this slim unit punches above its size.
all-in-one you need a hybrid Wi-Fi/4G system for a multi-entry home or property where sensor count matters more than camera resolution.
skip for outdoors you want a simple to use plug-and-play experience — this one rewards some patience during the initial pairing.
4. tolviviov 15-Piece WiFi Home Security System
Ten door sensors, a keypad, and a motion detector — enough hardware to cover a whole house in one box.
This is essentially the big brother of the 10-piece tolviviov kit above. You get ten door sensors (up from five), one motion detector, a keypad for arming/disarming from the wall, and two remote controls. The 120dB siren is identical, and the 8-hour backup battery is still there. Like the smaller kit, it runs on 2.4GHz Wi-Fi (no 5GHz support) and requires no monthly subscription. It supports expansion up to 20 sensors.
Setup is remarkably quick — owners consistently say it takes under an hour to get every sensor paired and placed. The contact sensors work well even on non-flush trim, which solves a common headache with other systems. The system is “very impressed” territory for most buyers who want a reliable, no-nonsense alarm network without cameras.
The only common hiccup is that you need a 2.4GHz Wi-Fi network; 5GHz-only routers require setting up an extender. A few owners also mention that the alarm sound quality is decent but not deafening. If you have a lot of accessible windows and doors, this 15-piece gives you the sensor density to cover them all without buying extra kits.
who it suits: Homeowners with many ground-floor entry points who want a single-box solution — ten contact sensors is more than most houses will ever need.
skip if: You want a camera in the same package — this is strictly a sensor-and-siren system; add a Wi-Fi cam separately.
5. XUK WiFi Wireless Alarm System, 24-Piece with 4.3″ Touch Screen
A 24-piece kit with a bright color touch screen that even kids and elderly family members can use.
The XUK stands out immediately because it replaces the usual numeric keypad with a 4.3-inch color touch screen interface. You can see the system status, time, and alerts right on the hub. The kit is full: ten door and window sensors, five PIR motion detectors, a 120dB siren, an SOS emergency button, three remote controls, and three RFID keychains. It supports both Wi-Fi and 2G/4G cellular (SIM card required for SMS and voice calls), so alerts keep flowing even during an internet outage.
The sheer expandability is the headline — the system supports up to 100 sensors and 10 RFID keychains, making it ideal for large, multi-story homes. Buyers who get it working love the “great flexibility of connection” and the fact that there are no monthly fees. The touch screen is genuinely user-friendly for all ages.
But the mixed reliability feedback is real. A few owners experienced a critical failure where the siren activated uncontrollably and could not be disarmed, requiring the unit to be unplugged. Others found the setup process confusing. If you want the most comprehensive sensor pack available and are comfortable with a little tinkering, this is the one. The reward is a huge, customizable security blanket for your whole property.
the big win: 24 pieces in one box, including a 120dB siren and five motion detectors — the most comprehensive kit here for coverage granularity.
note for cautious buyers: Reliability is a mixed bag in reviews; ensure you are comfortable with potential setup quirks before relying on this as your sole security.
6. PGST Wireless Alarm System, 24-Piece Home Security System
A large 24-piece kit that hides in a tiny hub — just 8 ounces and small enough to sit on a shelf.
The PGST system packs 24 components into a tiny footprint. The main unit measures 7.5 x 4 x 4 inches and weighs only 8 ounces, so it is drastically smaller and lighter than the tolviviov or XUK hubs. It connects via 2.4GHz Wi-Fi and supports a 4G SIM card for phone and SMS alerts. The siren hits over 110dB. The kit includes multiple door sensors, motion detectors, an SOS button, and remote controls. It works with the Smart Life or Tuya app and supports Alexa for voice control.
The main attractor is the SOS button and remote panic functionality — owners who replaced an older PI-Sector alarm found the 4G connectivity solid and the internal battery lasts several days without mains power. The color screen on the hub displays system status, weather, and date in ten languages. Tamper protection means the system alarms if someone removes the unit without entering the security code.
The mixed feedback comes from the initial app setup, which some found frustrating due to a default accessible mode. Also, the arm/disarm chirp is loud by default, though you can turn it off in the app. If you need the most sensors per cubic inch, this compact hub delivers without taking over your entry table.
standout spec: The hub weighs only 8 ounces — a fraction of the 5-pound SimpliSafe kit — so it mounts or sits anywhere without a second thought.
who it is for: Someone who wants maximal sensor coverage (24 pieces) in a minimal physical footprint, with the added safety net of 4G cellular backup.
7. SimpliSafe 6 Piece Wireless Home Security System with Outdoor Camera
The same trusted SimpliSafe ecosystem with one outdoor camera and three entry sensors for tighter budgets.
This 6-piece kit is the smaller sibling of the Best Overall pick at the top. It includes one Outdoor Camera Series 2 (the same 1080p HD, 140-degree field of view, color night vision camera), three entry sensors, a base station, and a keypad. It also comes with the same first free month of professional monitoring. At 12.3 x 12.38 x 4.4 inches, the physical footprint of the hub matches the 7-piece version, but you get one fewer outdoor camera and one fewer entry sensor.
The camera quality is the most-praised feature here — buyers consistently say the 1080p color night vision is excellent. Setup is exactly as simple as the larger kit; owners mention taking it from the start and getting it running the same day. It integrates with Alexa and Google Assistant for voice control. The optional monitoring keeps costs down for those who want professional response only on their terms.
The value-for-money is a mixed point. Some owners find the hardware affordable but note that the system “is limited due to its dependency on the purchase of a service package deal” if you want the full police-dispatch response. If you only need one outdoor camera to watch the front door and three sensors for the main entry points, this is the cheapest path into the SimpliSafe ecosystem.
best for: Renters or apartment dwellers who want the reputation and app quality of SimpliSafe but only need coverage at one exterior door.
think twice if: You need to cover two sides of a house — the 7-piece kit gives you a second camera for much more complete outdoor protection.
8. Abode Iota All-in-One Security Kit
An all-in-one hub that packs a camera, siren, motion sensor, and two-way talk into one sleek tube.
The Abode Iota is a different kind of system. Instead of a box of separate parts, the main hub is a single tower that houses a 1080p camera, a motion sensor, two-way voice, and a 93dB siren. It comes with one key fob and one door/window sensor. It connects via Ethernet or 2.4GHz Wi-Fi and is built around deep integration with Apple HomeKit, Alexa, and Google Home. The free app lets you monitor and control everything from anywhere.
The thing HomeKit users appreciate most is how quickly the Iota integrates with existing automations and geofencing — it just appears in the Home app and works. The system supports up to 160 total compatible security and smart home devices, so you can grow it significantly over time. It operates without any required monthly fees.
The honest trade-off is reliability. A number of customers note Wi-Fi connection issues and random chirping from the device. The 93dB siren is noticeably quieter than the 120dB sirens on the tolviviov and XUK systems. Some also found the self-monitoring features push you toward a paid subscription. If you are deeply invested in HomeKit and want a single-device security hub, this is the most elegant option — but it comes with more compromises than the simpler sensor kits.
perfect for: Apple HomeKit enthusiasts who want security automations (like lights turning on when an alarm triggers) without messing with extra hubs or bridges.
not for: Anyone who wants the loudest possible siren or a system that works 100% reliably from the start — this one has a higher disappointment rate than the competition.
9. aosu D1 Max, 6-Cam Kit, 4K Solar Security Cameras System
Six solar-powered 4K cameras with 360° PTZ tracking and no subscription — the ultimate outdoor surveillance kit.
This is the system for anyone who wants high-resolution video coverage across a large property without running wires or paying a monthly fee. The D1 Max ships with six cameras, each capturing 4K Ultra HD at 8MP with 6x digital zoom. They can read a license plate from 33 feet (10 meters) away. Each camera has a 360° pan-tilt-zoom (PTZ) motor and automatically tracks people and vehicles as they move. The built-in spotlights enable full color night vision, so you see a person’s face in color at 2 a.m., not just a black-and-white silhouette.
The cameras are solar-powered with a detached solar panel you can position for maximum sun exposure. The aosuBase hub keeps recordings secure locally on 32GB of storage, expandable up to 1TB — zero cloud or subscription fees. The Cross-Camera Tracking feature stitches clips from multiple cameras into a single timeline so you can follow a person’s path across your whole yard. Reviewers point out “sharp video day and night” and that the solar keeps batteries charged without any maintenance.
The practical limit here is the hub’s wireless range — some owners found signal issues beyond 70 feet, and the cameras occasionally miss motion events. The 360° PTZ (pan-tilt-zoom) cameras are also large and heavy; mounting them on vertical surfaces requires care. If your priority is crisp 4K video of every corner of your property with zero recurring costs, this kit is class-leading.
Solar powered cameras
- True 4K UHD (8MP) with 360° auto-tracking
- Solar powered — no wiring, no battery changes
- Local storage up to 1TB with zero subscription
Large camera size
- Hub range can struggle past 70 feet; placement matters
- Cameras are heavy and need solid mounting surfaces
who should buy: Homeowners with large properties or multiple outbuildings who want 4K video evidence without paying for cloud subscriptions.
who should skip: Anyone who just needs sensor alerts, or whose property is smaller than 5,000 sq ft — this level of coverage is overkill for an apartment.
10. eufy ExpertSecure System E10, Home Security Center
A whole-home security center with 4G connectivity, massive local storage, and every eufy device pre-configured from the start.
The E10 is eufy’s most complete all-in-one solution. The box includes a HomeBase Professional S1 hub, a keypad, a key fob, two entry sensors, one motion sensor, a SoloCam S340 (4K), a Video Doorbell C30, an Indoor Cam E220, plus yard signs and window stickers. All devices come pre-configured — you plug in the hub, and everything pairs automatically. The HomeBase S1 supports up to 36 sensors, 16 Wi-Fi cameras, and 4 PoE cameras, and it can output 4K video over HDMI.
The connectivity redundancy is what sets this apart. The hub has built-in 4G LTE and a 24-hour battery backup, so your cameras and sensors keep working even if the power and internet both go down. Storage is 32GB built-in and expandable up to 16TB via HDD — you can keep months of 4K footage locally with zero monthly fees. Buyers with long-term eufy experience call it a “hidden gem” that delivers the same reliability as professional alarm companies without the contracts.
The trade-off is that you are buying into the eufy ecosystem — older third-party sensors generally will not work. The mobile app can feel cluttered with ads for add-on services. If you want a turnkey, subscription-free security center that handles video doorbells, outdoor cams, indoor cams, and entry sensors all from one brand, the E10 is the most complete option here.
best for: Homeowners who want one unified system for cameras, doorbell, and sensors, with 4G backup for true off-grid reliability.
consider this: The upfront investment is higher than a sensor-only kit, but there are no monthly fees and you get a full video ecosystem that grows with you.
Understanding the Specs
Video Resolution: 1080p vs. 4K
1080p HD is the standard for security cameras. It provides clear enough detail to identify a person’s face or read a license plate in good light. 4K Ultra HD (8MP resolution) is four times sharper. It lets you zoom in digitally without the image turning into a blur — useful for reading plates from 30 feet away or identifying a person in a wider scene. If you can identify intruders from camera footage alone, 4K is worth the jump. If you just need to know if someone is at the door, 1080p is fine.
Siren Loudness: 93dB vs. 120dB
Decibels (dB) measure sound pressure. A 93dB siren is about as loud as a motorcycle idling nearby — enough to startle an intruder and alert the immediate room. A 120dB siren is as loud as a jet engine at takeoff from 100 feet away — it will hurt ears, wake the whole neighborhood, and is much more likely to drive an intruder away quickly. For home defense, 120dB is the standard to aim for; 93dB is acceptable for a basic deterrent but may not cut through closed doors or upstairs rooms.
Professional vs. Self-Monitoring
Professional monitoring means a security company watches your system 24/7 and calls the police when an alarm triggers. It costs a monthly fee but means you do not have to be glued to your phone. Self-monitoring means the system sends an alert to your phone, and you decide whether to call the police. It is free after buying the hardware but requires you to act quickly. Some systems (like SimpliSafe) offer professional monitoring as an option with no contract, so you can try it and cancel anytime.
Expandability: How Many Sensors Can You Add?
Most DIY systems let you add extra door sensors, motion detectors, or sirens later. The entry-level kits support 20 additional devices. Some, like the LWOHSI system, support up to 99 wireless sensors, while the eufy HomeBase S1 handles up to 36 sensors and 16 cameras. A higher limit matters if you have multiple outbuildings, a large house with many windows, or plan to expand coverage over time. A system with a 20-sensor limit is fine for a standard apartment; 99 sensors covers a large property.
