A useful night-vision comparison starts with the detail you need at a defined distance. Check recognition of a stationary target and how movement affects the record. A brighter image alone does not establish reliable identification or a temperature reading.
Define the requirement
Record the following for the proposed use: target detail; working distance; motion. Keep the exact model, configuration and observation date with that record.
