Cam snapshot

Configuration
1

Hi,
I’m using an automation with ‘cam snapshot’ service, my problem is that the new snapshot are not overwriting the old one’s - I get only my first snapshot, this is my code, can you advise?

action:
  - service: camera.snapshot
    data:
      filename: /config/www/tmp/snapshot-reolink.jpg
    target:
      entity_id: camera.cam_gate_sub
  - service: notify.mobile_app_lior_s_cell
    data:
      message: "Car get open "
      title: The car gate is open for more than 5 min - it will be closed in 1 minute
      data:
        image: >-
