Yes you can attach that to a Pi HQ camera. I can make no comment on the resolving power (resolution) that the lens can achieve. CCTV used to be SD resolutions equivalent to 720x576, so the optics typically matched.
A quick search gives me https://www.sourcesecurity.com/datashee ... 0A-M41.pdf as a datasheet for the lens. You have direct motor drives for each of focus, zoom, and iris, exposed via a 6 pin connector. Attach them to some H-bridge motor drivers, with the Pi or similar providing the control to the enable lines. You'll find numerous small boards with an L298N or similar that will drive two motors with direction control.
Do note that you have no read-back of the focus position, so you won't be able to recall positions at all, just do manual control. There are lenses with potentiometers in so that you can use an ADC to read the position. At some point I may get my Computar H16Z7516PDC working![:D]( "Very Happy")
