Base mount to shallow to allow release of adjusting mechanism with hex key when mount tightened against wall or soffit..
Have to loosen the 3 mount screws before there is enough room for adjusting mechanism to move when using hex key

Solved the spider problem by turning off camera IR illumination and installing separate IR illuminators a few feet away from cameras
Prefer the 940nm invisible IR over visible 850nm LED lights.. be advised 940nm IR illuminators have 50% less range than 850nm illuminators..
Separate IR lighting cuts down on movement false alarms from bugs, dust, snow, or rain reflecting camera IR illumination too..
