When a visitor presses the outdoor unit button, the video intercom system will automatically activate the indoor monitor, the bell rings and the live image is displayed. You can view the visitor outside, speak with them, and unlock the door remotely in real-time. Even if no one presses the doorbell, you can still monitor the outdoor activities and listen to outside sounds. This two-way communication method allows you to interact with unknown visitors without opening the door, making it both secure and efficient.
