If mounting the camera from the ceiling, connect the camera
penetration to the pipe with a pipe-to-pipe coupler. Manually tighten the
coupler, and then tighten the locking nut with a wrench.
Point ETS-Lindgren label
to center of desired field of vision
When the camera enclosure is completely connected to the pipe, the
ETS-Lindgren label on the enclosure should point to the center of the
desired field of vision.
5. If the ETS-Lindgren label does not point to the center of the desired
field of vision, slightly loosen the camera penetration nut and locking
nut to rotate the camera enclosure so the label is in the correct
location, and then securely retighten both nuts.
