Hi, I live less than 2 city blocks from a railroad my son wants to set up a YouTube live railstream. I bought an anran 1080p pzt with 20 times optical zoom and it works pretty good, but when the trains go by fast and at night it gets pretty choppy. I spent $180 dollars on it, and I was thinking about returning it for something better if it exists. I've seen cameras with 36 times optical zoom and I don't mind spending more money, but would that help with the chopiness? Is there anything anyone recommends? Thanks
