Greetings.

There are two solutions to your issue that I can think of, one of which is a little context dependent.  You state in your description that the plugs coming off your test screen are "two colored connectors (white and yellow)," which would be RCA video (yellow) and RCA Audio (white).  However, in your photo it shows 3 connectors; the one on the farthest right is a BNC video connection, which is the recommended video input to use for CCTV cameras for maximum compatibility and resolution.  If there are in fact 3 inputs to your screen, all you need is https://www.securitycameraking.....d-cameras/.  BNC video connects to the camera and the tester, power goes on one end to the power supply plugged into the wall and the other into the camera.

Now, if your first picture is showing the camera video connector along side the test connectors for COMPARISON, then you'll need an additional adapter along with the plug and play cable listed above.  This https://www.securitycameraking.....le-single/ RCA adapter would plug into the plug and play cable, and then plug into the yellow port of the camera.  Please keep in mind that video over RCA is generally very low resolution (max 480p, probably closer to 320p) so if that camera ONLY has RCA video as it's video output you may want to consider purchasing a system that's more up to date.  I can get you a 2 to 4 camera 1080p system that's easy to set up and comes with a 3 year warranty for around $300 if you feel like giving me a call.

Hope this helps.
