Yea I very infrequently here businesses installing
Blue Iris for clients. Maybe not in my area Atleast. But I think a quality CCTV installation company that spends the time to educate customers on quality cameras will be the #1 in the business. Unfortunately for my 1st property I got ripped off by an alarm installer who installed only 4 wide angle cameras 25 feet in the air (before I knew about this forum of course)
To be fair... my work place was a Toshiba business telephone system dealer and infrastructure cabling place since 1999. 2 pair, Cat3,
Cat5, Cat5e, Cat6, Cat6a, Cat6e, various fibers (multimode and single mode....mechanical splice and fusion splice). 98% geared towards cabling in walls, ceilings, warehouses red irons (think Home Depot), underground 3" conduits, etc. For business network purposes involved customer PC, remote switches, paging, digital phones, faxes, network printers, network mailing machines, smart tv's, etc. This is our main gig.
We are not camera dealers. Sure we install the cabling for them since we are already installing data cabling for other purposes.
I personally would love to bring in being a camera dealer ontop of business phone systems and infrastructure cabling. Since I have learned some of the do's/dont's, science, engineering involved with IP cameras, I would feel comfy being 100% responsible for them at work. But again, not my call

So I can not speak of CCTV installers as we have a more diverse business application than just CCTV.
