The best of both worlds! A call from your video doorbell rings the JO-1MDW monitor and up to eight smartphones or tablets. After answering the call, you can see and speak with your visitor then easily unlock the door with the touchscreen monitor or using the slider button on the app. The JO-1MDW is unique as it is a hardwired monitor to ensure calls are answered even when the internet is down or slow, while the mobile app establishes a connection when you're on the go. The monitor features built-in memory that can be manually activated to record video from the doorbell or set to automatically record all calls. Expand storage using the MicroSD card slot and view recorded calls on both the monitor and the app. All this security and convenience is backed by Aiphone's quality and award-winning customer support. Our commitment to your satisfaction is equivalent to our commitment to supplying quality products. Second to none. Use Aiphone when you need unparalleled product quality. Use the JO Series when you need on-the-go security and convenience in a single package.
