Great Job John ,
We try different camera manufacturers all the time , see how they perform on a job by job basis, if they do, we try others, if not we see why not and do not go on with them, we read all the write up's and review for a period of time to see if the stand the time test and not just snap reactions to reviews
Certain manufacturers have not adapted to a strict set of standards so we don't use or support them.
We treat surveys just like they are surveys, not facts, likes, dislikes per company or manufacturer.
Because our next job is based on reputation, not sales we don't take a lot of chances on company's that buy other company's and resale their products as the same product under a new name.
Even if the company is on the worst list , we look at all the facts 1st. still like some of their products as they perform.
Products, time as a company, experience in industry, background as a company and many more items to verify they stand the test of time and stability
A lot of the cameras on the worst list we have tried , they are still in operation today and no problems , they are not the latest greatest , but the don't or have not failed yet. and others are pieces of junk and would not recommend , costco, walmart grade .
Still some of the cameras are great , the company's on the list are still great in certain areas as they still perform to standard.
pelco, panasonic, axis, arecont, Hikvision all have great products and should be given credit for that.
like any survey , if you give a survey it is always biased to the people, place, demographics of that area or country.
My concern is not the list , but the same junk , under new name, and package sold as the latest greatest, and sold by some salesman who does not know the cameras from walmart from the high end camera from axis,arecont,panasonic, pelco. Just selling products ( just phone salesman) with a great line.
