Lenses are not "analog" or "megapixel", they have a resolution rating, and the rating of your lens should ideally meet or exceed the specifications of the camera you're attaching it to. Well, actually, all lenses are "analog" in a sense ;)
The spec sheet for this lens does not lists its resolution (usually a lp/mm (line pairs per mm) number). So it's reasonable to assume it is only rated for D1 resolution.
A good D1 lens will have a resolution of around 50 lp/mm. You'd want 100 or more for 720p/1MP, around 150 or more for 2MP, and so on.
The lens you list will "work" with a megapixel camera (assuming it mounts to it, image sensor physical size is appropriate, etc.), however it may prevent the camera from capturing images at its full potential.
Thanks for the quick reply!
The reason I bring up the question is that I would connect the analog output of the camera to a monitor for live viewing. The network side of the camera would be recorded by a Milestone server. So if I understand correctly, the worst possible outcome would be recording at D1 resolution provided the lense fits properly on the camera?
Boy, that's an old model! It's a 1" format so will cover most megapixel sensors (the focal length will still be correct despite this), it's C mount so you might need a 5mm spacer ring on modern IP cameras (most likely to be CS mount) and the resolution will need to be considered carefully; the spec sheet doesn't detail the resolution but I expect it is around 800-1000TVL equivilant. You should also look at how you're going to drive the lens and whether you need the preset functions, not sure who does telemetry receivers for IP systems... I'm sure someone from Computar (CBC) will fill in the gaps!
The lens will be driven by this remote control periscope:
It's on the top of page two. The one I'm actually am working on is the RCSS-3000. I called the company, and they said it's the same as the one in the catalog with the exception of the newer one is lower profile.
A Panasonic WV-CL924A was originally connected. During use, the coax cable was pulled from the back of the camera ripping out the electronics on the back of the camera. I managed to fix it short term but I'm looking to eventually replace the camera.
Do you have to use that lens? Doesn't Computar have MP zoom lenses?

Will it work? Yes. Will it work well? Probably not, depending on the camera.
Since there's absolutely no information on the quality of glass used to make the lens, you cannot assume the glass is good enough to shoot through. This will be an even bigger issue due to the multiple elements required to make a zoom lens, especially a zoom lens with such a narrow field of view and such a compact barrel. In short: it'll probably be blurry, and never focus right.

I would pick a camera with as large a sensor as possible, but below 1" obviously.
This will maximise the resolution of your system using this lens.
For example. Using this lens.. A camera with a 1/2" sensor will give better resolution than a camera with a 1/4" sensor.
I finally got to the point in the project where I replaced the old panasonic analog camera with the Sony IPELA SNC-CH120 I did some testing today and it's working great!! Thanks to all who replied!!
Yes! Works great! Was zooming into license plates well over 200 yards away.
