Schematics for Philips Video 40 CCTV camera
Hello.
Do anyone have schematics for a Philips "Video 40" CCTV camera with a 1/2" Vidicon tube ? I found some pics of one (the first three pics) http://picasaweb.google.com/AstroTas...58260120547554 Thanks in advance, // Per. |
Update: I found a "real" model number of the camera.
It's called LDH 0400/01 / NC 8925 040 00101 220V AC 50 Hz 8,5W :D I find it amazing that google cannot come up with a schematic or user manual, this is from Philips, they were a great brand back in those days. A funny feature of it - in the back there is a adjuster knob that controls the movement of the whole vidicon assembly up in the front of the camera via a turning rod, quite ingenious. // Per. |
Update 2:
Tried connecting my two Video 40's to my TV's CVBS input and a video capture card. All i get i a grey screen. Looking at the BNC connector, my cameras puts out this: http://zapro.dk/div/video40.jpg Waving my hand in front of the lens does change the video signal a bit on the scope, but still does not show up on a TV. Something seems fishy! The sync is inverted ??? Maybe the output signal is not CCIR standard video ? // Per. |

Edit: do you have a lens on the camera? If not, the automatic gain will set the general video level to 50% as you see. |
