Red55 0 Posted July 30, 2011 OK got together enough cash to upgrade my front door camera to a CNB VCM24VF. Manual says to wire to + and - terminals. No problem except my green adapter at the plug has no such markings? Traced out the leads to a red and brown wires at power input JK502/503. Would I be correct in assuming that red is positive? Already have 12VDC at camera location. Thanks, Ed Share this post Link to post Share on other sites
rory 0 Posted July 30, 2011 Polarity does not matter with that camera. You can put red and black on either side of the green connector. Share this post Link to post Share on other sites
Red55 0 Posted July 30, 2011 Thanks Rory! Did not want to find out the hard way. Figured the green adapter was actually for 24VAC. Share this post Link to post Share on other sites
Soundy 1 Posted July 30, 2011 It's dual-voltage. Actually, it's multi-voltage. IIRC, that camera will accept any input voltage from about 10V to 30V, AC or DC. The internal power board rectifies and regulates it as needed. Share this post Link to post Share on other sites
