The photocaller function takes an automatic snapshot of anyone who rings your doorbell, with the date and time when they were taken. The photocaller of WI-BOX stores the last 10 pictures of registered calls, whether answered or missed.
To free up space in the device's memory, the images are deleted weekly every Tuesday night.
If you try to view a photo from the app, this will send a request to the WI-BOX device to access the photo, then the photo will be downloaded and stored in the memory of your smartphone, so it will not be lost.
The second time you view the photo, the request is no longer sent to the device, but is retrieved from your smartphone's memory. In other words, if you have not yet viewed the photos from the app, those unviewed photos will be deleted next Tuesday evening.
Please note that if the power goes out or the module is forced to restart, the photos that have not been downloaded on your smartphone will be also lost.
