Is your parking ticket meter, hydrant or parking sign violation? If a parking sign it is important to have exact time/date, vehicle description and location/address. You can verify every parking sign in NYC via https://nycdotsigns.net/ and put in the address. I believe you have two methods to defend -
photo/location of where you were parked including vehicle and perhaps take still photo and video 360. Best, if done with ticket in hand and verify you had date/time in your video to confirm date/time (e.g. cell phone plus time stamp of image)
If the address on the ticket violation doesn't match the parking sign at that actual address (if it exist) - it will be dismissed anyway.

The challenge I see is if an agent wrote a hypothetical ticket for 120 Broadway with a no standing zone 9a-5p and issued ticket at 9:01am. But, you parked at 120 West Broadway - you will need to prove your location as anyone could use that defense. This response is quite late vs. original posting so hope it helps.
