Can lawyers investigate and collect evidence for hotel surveillance?

No, you need to issue a letter of assistance in the investigation to obtain monitoring. Investigation letter is a letter sent by judicial organs to other units to request their assistance in investigation according to the needs of investigation. Individuals certainly do not have the right to access hotel surveillance video. Only when the public security organ has the right to access the hotel's surveillance video can the case be solved. Although the public security department has this power, there is no case of going to the hotel to collect surveillance videos at will. I hope I can help you.
