Want to know who's at your door without having to get up to see? Then the UmikSmart X7 Video Doorbell and monitor set is just what you need! This sleek white system consists of an outdoor doorbell camera paired with a portable indoor 4.3" 1080p resolution color screen monitor with 130° wide-angle lens for optimal real-time visitor identification. It uses a 2.4G wireless signal to communicate between the doorbell and monitor, *requiring no Wi-Fi or internet*! The built in microphone and speaker allows for two-way audio. PLUS, it features high-definition infrared night vision for clear visibility in low light. The doorbell comes equipped with an 800mAh rechargeable battery that will last at least 3 months between charges, and the monitor has a 400mAh battery allowing for 2 full hours of continuous portable use. Both have USB-C ports and can be recharged in only 1.5 hours. They are lightweight and can be mounted without the use of drilling, using adhesive stickers instead, making it suitable for apartments or rentals where drilling may not be allowed.
