Recording resolution

What is the optimum recording Resolution? Do you need full HD or is 720P enough? Or even just 640-480 (US). Just looking for ideas, comments.

Low res is acceptable and you get more in the memory if its only for your personal reminder of how something went.

If its going to form part of a product ability or demo then higher is generally more preferable, particularly if its demonstrating night vision performance.

It depends on the sensor you're using to create the images you want to record.
Most high sensitivity NV and thermal sensors are relatively low resolution and output analog video signals, so the best you can do is D1/960H quality.
If the sensor output is analog video you cannot record in HD because the signal formats are entirely different
If you have an HD sensor, you can record in HD, but be aware that as sensor resolution increases (there are more pixels creating the image) the sensitivity reduces (the pixels creating the image are smaller)
As Dave says, the higher the recording resolution, the more memory space is needed to record for a given time.
