Cellular/LTE Security Camera with Solar or DC power that integrates with HA

Hi there. I am looking to mount a security camera on my gates at the end of a long driveway (1/2 mile) to my home. There is no power at the gates other than solar panels and batteries for the gates themselves. I would like to place a security camera there that at the very least sends still images as motion occurs or potentially live video. I have no way of getting an internet connection to these gates as the road is hilly and heavily treed. I have considered trail cams but would really like to know if anyone else out there has come up with a solution to a similar situation.

I think it would be great to setup an automation that throws a still or live image from the camera up on the TV when movement is detected.

Any info is appreciated. Thanks.

Have you looked at some trail cams?

Some have built in cellular service. I know Bushnell & Browning make some that work internationally.

Thanks for the reply. Yes, I have considered them but am wondering how I could integrate the output of a trail cam into my HA system? Some sort of intake via email for the still image triggering an automation?

Some theoretical ways I can think of -
if there is a developer API,
if the camera sends email with attachments, FTP, cloud storage, or similar, that should be able to be implemented in HA.
If a proprietary app must be used, a short script identifying new picture in the app’s picture storage location.
