Tuya M21 WiFi Video Doorbell: Intelligent night vision with white light compensation
This WiFi video doorbell is designed for homeowners who want to know who's at the door without getting up from the couch. It's perfect for monitoring deliveries while you're at work or keeping an eye on kids playing in the front yard.
While many focus on home security, this camera offers peace of mind for daily routines. The 155° wide viewing angle captures your entire porch, so you never miss a package left at the edge. The two-way audio lets you tell a delivery person where to leave a box, and the intelligent night vision ensures you can see clearly even when motion lights don't trigger.
You'll appreciate how the PIR motion sensor sends alerts to your phone before your dog starts barking. The 4000mAh battery lasts for months, and IP65 waterproofing means it handles rain without a fuss. Use it with Alexa compatible devices for hands-free checking, making this indoor camera or home security camera a practical addition to your smart home.
