When you're securing your home, the first fork in the road is whether you need to know when a door or window opens or actually see what's happening outside. The Zigbee Door Window Sensor and the Google Nest Cam With Floodlight sit on opposite ends of that decision and of the price range. The price gap is wide, so your choice comes down to what kind of coverage you want.
Quick Verdict
If you're starting from scratch with a tight budget, the Zigbee Door Window Sensor gets you entry-point alerts very cheaply. If you need a security camera that can light up and record your yard, the Google Nest Cam With Floodlight is the stronger pick.

Where Each Wins
The sensor wins on price and simplicity. The camera wins on coverage. If your priority is catching entry-point activity without spending much, the sensor does that job. If your priority is seeing and lighting up the outside of your home, the camera is the clear choice.
Zigbee Door Window Sensor
The Zigbee Door Window Sensor is a low-cost, battery-powered way to get alerts when an entry point opens. It uses Zigbee 3.0, so you'll need a compatible hub or a voice assistant with a built-in Zigbee hub; without one, it won't function. The package includes the sensor, CR2032 battery, reset needle, double-side adhesive tape, and manual. For $7.99, it's an easy add-on to an existing Zigbee setup, but it only detects open/close events and can't provide video or outdoor lighting. That makes it best for renters or budget builders who already have the hub hardware.
Google Nest Cam With Floodlight
The Google Nest Cam With Floodlight is a wired outdoor camera that pairs a security camera with a floodlight, and it's designed to withstand the weather. The catch is that this listing is for open-box units: the seller notes they came from returns and have not been tested because they're hard-wired installs. The units are described as in very good physical condition, and multiple units are available, so the one you receive may not be the exact one in the photos. If you're already in the Google Nest ecosystem and need powerful outdoor surveillance with lighting, this is a strong option at $164.99, but the untested, open-box status is worth factoring into your decision.
Final Choice by Use Case
Choose the Zigbee Door Window Sensor for entry-point alerts on a budget. Choose the Google Nest Cam With Floodlight for a complete security camera and floodlight combo.
