I purchased the 4k system from Costco, about $2000 for the 16 camera NVR system with 8 cameras. I then purchased the hard drive upgrade to 20TB for $700 from Avertx so I can store more days of pics. I emailed Avertx customer service after the purchase so they can upgrade the system to the larger hard drive. Customer service was easy to deal with and got the upgrade done.
There are way too many security camera companies out there, all with some sort of negative reviews. Many of the so called review websites are just shills for the company being promoted as best, a troubling new
marketing trend especially in the security business.
Vote is out if I made a smart move as I am installing the cameras on Monday. Can update the quality and ease of installing. My current 1080 cameras show me the action but it I need to show something to police the picture is not great for IDing a person. 4K with zoom ability should be a big improvement.
