Here we go? As someone who has been THIS BUSINESS (Military, Industrial, and commercial CCTV) for over 45 years, be very careful about what and how you want to see and how you want to record the visuals. This can get very costly due to the environment and where the placement of the cameras need to be placed.
Please get all the ducks in a row and be sure to have your RFQ in your hands for your company of choice. Please understand what equipment you are getting too.
Another factor is maintenance. We need to know “going in” that we have some serious environmental considerations too.
Yes, as was mentioned, we have never had a problem…so what would the budget be to do what you feel would give you the coverages you seek.
