Start with emf or thermo to find the ghost room first then place dots projectors in central spots for good coverage specially near doors and common ghost paths. For bigger rooms use multiple projectors to avoid blind spots but keep em centered. Mount video cameras on tripods at mid-height, making sure nothing blocks the view of the whole dots area, and turn off the room lights for better visibility.

From the van monitor the camera feed with night vision off, gives you clearer view of those silhouettes when they show up. Good to know that goryo only shows dots through cameras so dont waste time looking in person. Watch the feed for at least 2-3 minutes since ghosts can be slow to trigger those green dots, and remember to angle your cameras right to catch crawling ghosts too.

Usually works best to put tier 2-3 projectors against walls or on the floor while using tier 1 for quick sweeps through doorways. Keep an eye out for motion sensor triggers, thats where you want your dots coverage focused. Just make sure youre patient with the monitoring, and dont forget that darkness is your friend for spotting those ghostly figures better.
