When you're choosing a home security system, the first decision is usually about how many entry points you need to cover and how much centralized control you want. The eufy 5-Pcs Wireless Alarm System Smart Home Security Kit Motion Sensor with App and the tolviviov WiFi Wireless Home Security Alarm System, 8-Piece Kit with Door Sensors sit at opposite ends of that trade-off. The eufy kit is $49 more, while the tolviviov kit costs less and puts more sensors into the box. The real question is whether you want centralized control or broader entry-point coverage.
Quick verdict
If you want a compact system with centralized control, choose the eufy kit. If you want broader entry coverage, choose the tolviviov kit-it packs more sensors and remotes into the box.

Product notes
eufy 5-Pcs Wireless Alarm System Smart Home Security Kit Motion Sensor with App
The eufy kit bundles a keypad, motion sensor, two entry sensors, and a HomeBase into a five-piece package that works with the eufy Security app. It is the more controlled option here: the keypad lets you arm and disarm without using your phone, and motion/PIR activation plus a light sensor sit alongside the entry sensors. The kit connects over Wi-Fi with battery backup, battery, and plug-in options, and the entry sensors and motion detector are designed to go about two years on one charge, with the keypad lasting about six months. It can also link with eufyCam and take an optional 24/7 protection service. The trade-off is physical coverage: two entry sensors and one motion sensor fit smaller apartments or a single main entry better than a larger home with many exterior openings.
WiFi Wireless Home Security Alarm System, 8-Piece Kit with Door Sensors
The tolviviov kit is the coverage-first pick. It includes one alarm siren station, five door/window sensors, and two remote controls, and it connects to a compatible 2.4GHz Wi-Fi network for instant alarm notifications to your smartphone with no monthly fees or subscription. The system is expandable, supporting up to 20 sensors and 5 remote controls or keypads, including compatible door, window, motion, water, and wireless doorbell options. That makes it easy to monitor a house with several entry points without a long-term plan. The limitation is in what arrives in the box: the core experience is entry-point coverage, so motion detection and a keypad are future additions rather than included features. If you want those controls immediately, the eufy kit is more complete on day one.
Final choice by use case
For a smaller apartment or a home with just a couple of exterior doors, the eufy 5-Pcs kit is the better fit because it keeps control in one place while still covering the main entry points.
For a house with multiple exterior doors and windows, the tolviviov 8-Piece kit gives you more sensor coverage out of the box, and its expansion options let you grow the system as you add rooms or openings.
