You can find the detailed set up video at the end of the main images on Amazon page.\nPair with Chime - To make sure you hear the ring even from afar, EZVIZ pairs it with an indoor chime. What’s better, the chime can help extend your Wi-Fi signal, and boost the network for the doorbell to ensure it get connected stably – which many wireless doorbells may struggle with. Please put the chime into a power outlet (within 5 meters from the doorbell).\nWide Field of View - With a 176-degree viewing angle, you can easily see the postman from head to toe and know where he places your package. The doorbell also comes with several different mounting plates in the package, which can help adjust the angle of installation to optimize the doorbell’s vision.\nPIR Human Motion Detection - With both human-shape and PIR detection capabilities, the device is smart enough to distinguish people from pets or objects. You can customize the alert trigger conditions to adjust its sensibility. Answer before you get the door for friends or deliveries! Using the EZVIZ App, you can talk and react with only a simple tap.\nTwo Storage Options: You can insert a microSD card (up to 256GB) into chime to save your recordings locally, without worrying about any data loss even if the doorbell is damaged or lost. You can also subscribe to EZVIZ CloudPlay for unlimited storage space and an additional layer of data protection with a free trial.
