Hello new member looking for info for research project

[mechalec 1]

Hello all. I'm an electronics tech looking for a video recording system to order either as an all in one system or piecing together the right components to make my own. I wanted to introduce myself since I'm new here and was doing some research for a system for our research dept. I'm looking to present 3 options: a barebone system, something in the middle, and a high end system. As far as the system goes, I am looking for the following:

 

At least 4 Cameras

High Resolution

Great Zoom (Cameras will be mounted on top of a mast from as far as 10' or closer, but need to be able to have really good focus)

One with a HDD

The ability to network the system for remote access

Durability (It's going to reside in an industrial environment)

Remote focusing would be a plus

 

Thanks for any help or routing me in the right direction.
