I’m using firmware 18.104.22.168 on GDS3710 hw version 1.6A, and the “Snapshot when Door Opened” feature does not behave like the “Snapshot when Doorbell Pressed” which is immediately below it on the configuration page. Ideally, either both should be governed by the ftp/email checkboxes on the “Snapshot when Doorbell Pressed” line, or there should be similar checkboxes to select ftp/email on the “Snapshot when Door Opened” line.
My guess is that the feature is presently only able to upload these snapshots via ftp, which I do not have easily available in my gate system right now. I would prefer to use the same email to receive snapshots on both types of events.
I receive no email snapshot right now when the door is opened, but I do receive the emails correctly when the doorbell is pressed.
