Long Pendant Mounts For Warehouse

I have a facility that is prone to frequent changes in need of some pendant mount cameras. The ceilings are about 35' high and I need to come down about 20' to achieve usable views. Can I utilize rigid conduit to drop these down far enough without possibly causing issues with vibration, stability, etc? I am utilizing Axis cameras. While their telescoping poles are great I need to reach down a bit further than their poles allow.
