I need some suggestions, the system I'm working on was installed 20 years ago, I'm running all new cat6 lines and 8mp cameras. They had originally installed a doorbell camera inside a standard sized junction box in the wall with a one way piece of tinted Plexiglas as the cover, this system has worked perfectly but it's time to upgrade to a 8mp ip camera, do any of you know of a camera that would fit in the box or have you ever heard of this type of setup before?
