I have been asked to figure out the cost of upgrading some old outdoor cameras. They currently are Sony SNC-RZ25N PTZ's in what looks like (from the original quote 8 years ago) FDP75T2N heated cases.

I was thinking about trying to use a hikvision PTZ. Are there any that would fit in such a case or would I need a new one? If yes, what is a good heated case for the Hikvisions or are they no longer needed.

 

Thank you
