Bell J9 Plus Wireless Video Doorbell with 180° Head-to-Toe View
The SITERWELL Bell J9 Plus is a battery-powered wireless video doorbell with a 2K, 1728 × 1728 square view and a 180° field of view. The square frame is what makes the head-to-toe view possible — you see the visitor at the door and the space around their feet in the same shot, so a package left at the step does not fall outside the frame.
Because it runs on a rechargeable battery, there is no doorbell wiring to connect. Mount it at the door, pair it over Bluetooth, connect to a 2.4 GHz Wi-Fi network, and check the live view and alerts from your phone. Recordings can be stored on a microSD/TF card, and optional cloud storage is also available.
MicroSD/TF card is not included and must be purchased separately. Cloud storage is optional and not included. Battery life depends on activity and environmental conditions. 5 GHz Wi-Fi networks are not supported.
