DC auto iris lens with a regular arecont camera?

[Flicks 0]

I have been reading this forum to help with my diy project for my home. I have now across an issue that i cannot find an answer with the search function. I have an arecont 5100dn camera (without AI) and a fujinon MP dc auto iris lens. How do i use this lens with the camera? Is there a way to open the iris (like by applying dc voltage to pins x and y) and keep it open to use it with the non AI arecont?

 

Any help will be greatly appreciated.

 

Thanks.

I did this, took a pot to see what it took to keep it open and used that value with a little margin. I think it ended up being around 400 Ohms for the one I tried, but could be wrong on that. Connectors can be obtained from mouser, there are links if you search around the forum a bit.

Also would love to see some night images of this camera.

IMO you have to have a significant amount of light.

I set one up on a tripod in front of my truck with the truck sitting on the street so I could get the camera as close to the traffic without getting it run over.

Standing in my driveway looking at the street there is a street light one house to my left and 2 houses to my right.

The motion blur was so bad all you could see was streaming tail lights.

You have to use the AV100 software to setup the cameras exposure correctly

Thanks Mike. I was able to make this work by using your tip. Used a 1k ohm (0.75 Watts), 15 turn Cermet Potentiometer (Part #271-0342 from Radio Shack) across the drive coil of the lens and kept adjusting the resistance till the lens opened up. Excellent advice " title="Applause" /> " title="Applause" /> " title="Applause" />

 

I hope the lens can be used now in this configuration. Does this cause any damage long term Please let me know if there is a better way to use an auto iris lens on a manual iris camera.

 

Thanks.
