What if the camera of 5E-AF4000 has been broken?

Normally, there are two ways to install the camera of the ash fusion 5E-4000. One is by use the mirror, we use the mirror to reflect the ash corn image. The other way is to make the camera aim the furnace directly. There is a problem that if we use the first way to install the camera , we need take care the distance between the camera and furnace. When the machine working, it will heat the temperature from indoor temperature to 1600℃. If the camera too close the furnace，it is easy to destroy the camera by high temperature. So we need keep enough distance when we install the camera.
