Can you still check the hotel surveillance from three years ago?

I can't. Generally speaking, at present, the storage time of surveillance video is generally not more than one month, and at most not more than three months. If there was no backup file at that time a year ago, it would be gone and never seen again. If there is nothing after the monitoring three years ago, hotels generally will not keep it. To sum up, the hotel monitoring three years ago could not be viewed.
