Where we use to live there were camera's high on entrance posts and the time and a photo of the vehicle entering were recorded when the gate(s) opened. If there was a question on the property we could pull the records, (e.g. dates
and times) and using that pull up a picture of the vehicle entering. This was done because of the number of people using the property to get to the beach when they were not residents or visitors. I truly don't understand why this cannot be done at the gate in question. Put a camers "High" on the post record the times and pictures when the gate opens or closes. It would be easy to identify who is breaking the gate either by accident (questionable?) or on purpose (more likely) and bring the appropriate legal actions. It would be cheaper than conitinuing to repair damages.
