When you're weighing your home security options, the central question is whether you need to monitor entry points or keep an eye on the outside of your house. The tolviviov WiFi Wireless Home Security Alarm System, 8-Piece Kit and the Google Nest Cam With Floodlight take different paths, and the right one depends on where your risk feels greatest.
Quick verdict
If you want to know immediately when a door or window opens, the tolviviov alarm kit is the practical choice. It provides broad entry-point coverage without a subscription. If you want a bright floodlight and video monitoring for the exterior, the Google Nest Cam With Floodlight is the better fit, provided you're okay with a wired, open-box unit.

Product notes
tolviviov WiFi Wireless Home Security Alarm System, 8-Piece Kit
This kit gives you a complete entry-point alarm setup at $110.99, including one alarm siren station, five door/window sensors, and two remote controls. That makes it easy to protect multiple doors and windows in an apartment or house without needing a professional installer. It can send instant notifications to your smartphone over WiFi, and the system is expandable to support up to 20 sensors and 5 remote controls or keypads, so you can add motion, water, or wireless doorbell detectors later. There are no monthly fees or subscriptions, which keeps the long-term cost predictable. The trade-off is that it doesn't include a camera, so you'll get an alert but no visual of what triggered it. If you need to see who or what caused an alarm, you'll need a separate video device.
Google Nest Cam With Floodlight - Wired Outdoor Smart Home Security Camera
This wired outdoor camera combines a floodlight and a Nest-compatible smart cam, so one fixture can light up your yard and record what happens. It's weatherproof and designed for exterior use, which makes it a good fit for covering a driveway, porch, or side entrance. Because it's wired, you'll need to handle a hardwired installation, which is more involved than plugging in a camera. The listing is for an open-box unit in very good physical condition, with all hardware and components included, though the camera hasn't been tested because of the hardwired install. That's the key limitation to weigh: you're getting a unit that may require some setup effort and hasn't been verified before shipping. Choose it if you value outdoor video and lighting in one package and are comfortable with an open-box wired device.
Final choice by use case
Choose the tolviviov WiFi Wireless Home Security Alarm System if you're a renter or homeowner who wants broad entry-point coverage with no monthly fees and doesn't need a camera. Choose the Google Nest Cam With Floodlight if the outside of your home is the main concern and you're prepared for a wired install on an open-box unit.
