Questions · Cameras
Dome or bullet? Which one suits me?
The place decides, not taste: the dome goes where the camera is within arm's reach or where you do not want it obvious which way it is looking, and the bullet goes where you have to reach a long way, with a long lens and a shroud to protect it from the sun and from driving rain.
The real difference is the bubble. A dome puts a polycarbonate dome in front of the lens, and that dome gets dirty, reflects and, with the infrared on, throws light back into the lens itself if the internal sealing is not good. In exchange, it is harder to knock out of position and birds do not perch on it. A bullet has no dome, so the image comes out cleaner at night, but it is a tube aimed from outside, and at head height anybody can move it.
There is a third case that gets forgotten: in high, clean interiors, the dome hangs from the ceiling and takes up no wall; on a façade, a bullet with a shroud stops water running down the glass and leaving streaks that show up on every image taken in the rain.

A written answer is enough to decide whether it interests you. To know whether it works at your site you have to see it on a real scene, with the image as it is and, on top of it, what the system understands from it. That is on the IRIS Neural website, which is the group's product.
