Choosing a home security system often comes down to balancing upfront cost, the number of sensors, and how you want to control it. Two DIY kits stand out: the tolviviov WiFi Wireless Home Security Alarm System 8-Piece Kit and the SIMPLISAFE Home Security System Easy to Set Up 11 pc + Accessories. Both are designed for easy, no-professional-install protection, but they make different trade-offs. Here's how to decide.
Quick Verdict
If you want the lowest price and a kit that already includes a keypad, motion sensor, and panic button, the SimpliSafe 11-piece at $79.99 is the more complete starter bundle. If you prefer a WiFi-connected siren station with five door/window sensors and two remotes, the tolviviov kit at $110.99 offers straightforward phone alerts and room to expand.

Where Each Product Wins
tolviviov wins for expandability and notification control. With a 2.4GHz WiFi connection, the system can send instant alerts to your smartphone, and it supports up to 20 sensors and five remote controls or keypads. The inclusion of five door/window sensors makes it a strong choice if you have several entry points to monitor.
SimpliSafe wins for value and complete starter coverage. At a $31 lower price, it gives you more pieces right away, including a motion sensor and a panic button. The integration with Google Assistant, Amazon Alexa, and Google Home makes it an easy fit for an existing smart-home setup.
tolviviov WiFi Wireless Home Security Alarm System, 8-Piece Kit with Door Sensors
At $110.99, the tolviviov kit is built around a central siren station that connects to a compatible 2.4GHz WiFi network. It ships with five door/window sensors, which is useful if you want to monitor multiple entryways. Two remote controls let you arm and disarm without walking to a keypad. The system is expandable to up to 20 sensors and five remotes or keypads, so you can add motion, water, or wireless doorbell devices later. It also provides instant alarm notifications on your smartphone, and the listing highlights that no monthly fee or subscription is required. The main trade-off is that the base kit covers doors and windows but doesn't include a motion detector or keypad, and you'll need a 2.4GHz network to use the WiFi features.
SIMPLISAFE Home Security System Easy to Set Up 11 pc + Accessories NIB
Priced at $79.99, the SimpliSafe kit is the lower-cost way to get a fuller security bundle. It includes an 11-piece setup with a keypad, motion sensor, panic button, and entry sensor, so you get more control and detection out of the box. It works with Google Assistant, Amazon Alexa, and Google Home, making it a good fit if you already use a voice assistant. The system runs on batteries and is listed in open-box condition, so the physical packaging and contents may reflect that. If you want a white system that integrates with your smart home and comes with a panic button, this is a solid pick. The open-box condition is the main caveat, but the lower price and included motion sensor give it a strong value story.
Final Choice by Use Case
Choose the tolviviov kit if you want a new, WiFi-connected system with five door/window sensors, two remotes, and the ability to expand to 20 sensors over time. Choose the SimpliSafe kit if you want the lower upfront price, a keypad, a motion sensor, and voice assistant compatibility without adding extras later.
