> technicians from Flock

Do they even have their own technicians? I believe there have been Dish Network technicians seen working on and setting up flock cameras and even those technicians are contractors of Dish network.

Mix of. Large metros they'll use their own staff to install, rural Americana they'll use Dish's OnTech division. Dish realized they have an entire 'trained' workforce of cable/dish techs that they can put to other technical use, so they pushed into more managed hands tech services.

I noticed a more prominently branded "OnTech" van roaming around my rural slice of life that had a smaller Dish brand logo on it that seemed to be more of that side of the business.
