Hi, i think i have ghost in my bedroom, so i want to record it with camera all Night. Can i record with my i phone ?

Keep it plugged in the charger, and make sure you change the battery settings so that your phone won't go into rest mode. Good luck, listen closely in your room when you go to bed any ghost will make a sound, don't be scared, The worst that could happen is you getting really cold then not being able to move in the middle of the night, because of an angry spirit.

if that's all you have, sure. just make sure you can plug it in so it charges all night.

You can't record something that doesn't exist.
