• “P2.5” refers to the pixel pitch of the LED module: 2.5 mm. That is, the distance between the centre of one LED cluster (one red-green-blue group) to the next. A smaller number → finer resolution / sharper picture at closer viewing distances.

• With P2.5 you can view quite close (often 2–3 meters or more) before noticing pixel structure.

Dahua has several “P2.5” models. Some are fine-pixel pitch (indoor, high resolution), some more general full-colour display modules. Some of the common ones are PHEIA2.5-TH, PHEIA2.5-SH, PHSIA2.5-LF, etc. Dahua Technology+2Dahua Technology+2
