If you're putting together a home security setup, the first fork in the road is usually between contact alerts and video coverage. Two affordable entry points face off here: the Zigbee Door/Window Sensor at $7.99 and the Wyze Cam OG at $20.00. Each tackles a different job, and choosing the wrong one will leave you with the right tool for the wrong problem.
Quick verdict
The Zigbee Door/Window Sensor is the lower-cost way to add entry-point alerts. The Wyze Cam OG is the more complete visual monitor, since it records video. If you need evidence rather than an alert, the Wyze Cam is the fit; if you just want an alert when an entry point changes, the sensor is the fit.

Where each product wins
Zigbee Door/Window Sensor: Wins on upfront cost and simplicity. It pairs with a Zigbee network and comes with the CR2032 battery you need to get started. It doesn't record video, but it makes entry-point changes known.
Wyze Cam OG: Wins on visibility. You get 1080p Wi-Fi video, night vision, and weather resistance for indoor or outdoor placement. That makes it far more useful for knowing what actually happened, not just that something changed.
Zigbee Door/Window Sensor
This sensor is made for a Zigbee-based smart home. It detects when a door or window opens and closes, then sends that status change over Zigbee 3.0. You'll need a Zigbee 3.0 gateway to use it, and if you want Alexa or Google Assistant voice control, you'll need that hub built into one of those devices. It won't link to Alexa through Smart Life. The package includes the sensor, a CR2032 battery, reset needle, user manual, and double-sided tape. The limitation is a real one: without a compatible Zigbee 3.0 gateway, this sensor has no way to tell you anything.
Wyze Cam OG
The Wyze Cam OG is a video-first security camera that captures 1080p over Wi-Fi in a 16:9 picture, with color video and night vision. It's designed for indoor or outdoor placement, so you can mount it where you actually need eyes. The box includes the camera, power adapter, and microUSB cable. It also fits alongside Wyze and Google Nest gear, which is handy if you're building a system around those brands. The main limitation is condition: this is a refurbished unit in Good condition, so it isn't brand-new and your experience depends on the refurbishment quality. For the price point, it offers visual evidence that the sensor simply can't.
Final choice by use case
If you need open/close alerts on entry points and you already have a Zigbee 3.0 gateway, the Zigbee Door/Window Sensor is the lower-cost addition. If you need a visual record of activity, or want outdoor coverage without adding a hub, the Wyze Cam OG is the straightforward pick because it only needs Wi-Fi. Choose the sensor for status updates and lower upfront cost; choose the camera for answers you can see.
