As usual, Brother canary, you hit the nail on the head with this issue. This is an attempt by the company to single out one group of employees (Unionized) as the supposed guinea pigs...drivers of...TRUCKS! While the sales force, et al, are excused. I’d have an old hat or rag ready to drape over the camera.
Some Friends of mine at Covenant tried eliminating the (earlier version of a) "Lane Deviation" ALERT (crossing a line without using a turn signal [like it's even possible in Construction Zones and engaging 4-ways helps not]). They actually reduced the SUDDEN NOISE thru Tape and a Towel till the Company simply acquired New Trucks. The NOISE now emits from the LEFT LOWER stereo speaker thereby eliminating a NOISE abatement procedure.
(Some Drivers under the earlier NOISE version simply "cut a wire at the ALERT speaker" [which was mounted over Passenger Seat] thereby relegating their Employment Status to that of UNEMPLOYED [or maybe unemployable].)
The Driver Facing Cameras in most Trucks are, as "claimed by Safety Divisions", Not Continuously Engaged In Recording Driver Expressions, Sounds or Actions until a Safety Event causes Camera to engage.
Safety Event(s): SUDDEN BRAKING, Sharp Turns (or Sudden Sharp Turn), or as deemed necessary by someone in "safety or dispatch".
Forward "recording" is (a) continuous (loop).
Putting a "covering" (hat, bandana, black tape [my preference]) upon Unit disengages Unit from Proper Function and results in Disciplinary Action (like in Elementary School): go see the principal or director.
I got banished from 1 company for the tape reason alone. (I drive Part Time for a Local "Driver Service".)
Harris-Teeter has Driver Facing Cameras in all their trucks that are not Switchers Units.
I found a way to "defeat" the ME facing cameras (since they're mounted at TOP of windscreen): Lower Driver Visor!
Since ALL Trucks are VOLVO, Driver Visor is Longer yet doesn't corrupt forward view as just a few inches is a satisfactory maneuver.
Harris-Teeter also claims: "Drivers shall not talk on Phones even WITH a hands free Headset, nor shall they Eat Food or Drink Fluids while Driving". So then you're an Automaton, no thanks.
I no anymore drive their equipment, for those and additional reasons.
I Hope Safe and Pleasant Journeys To Thee and Thy Loved Ones!
