sexydadee 0 Posted October 21, 2010 I have here a client specs that says they require fixed dome camera with integral lens of 2.6 to 6mm DC Iris Lens. To my understanding, Fixed dome cameras are fixed lens cameras. So I don't get it when they mention 2.6 to 6mm DC Iris lens.... Can somebody help clarify this for me? Thank you very much. Update: read up on it... i guess they are looking for a varifocal lens. my question now is. is there such a thing as automatic varifocal or all varifocal are adjusted manually?

Bean00 0 Posted October 21, 2010 There are a handful of fixed cameras with zoom lenses but generally speaking they all need to be adjusted by hand. Share this post Link to post Share on other sites
Soundy 1 Posted October 21, 2010 "Fixed dome" as opposed to PTZ - just means you have to adjust the camera position manually, and it remains fixed after that. Most dome cameras you find with "automatic" varifocal will be PTZs. Share this post Link to post Share on other sites
