Squiggly lines can be from a number of things such as cable interference, bad terminations and the most common insufficient amount of power.
You stated that you are using a PTZ camera. Most PTZ cameras do typically require a higher amperage power source because of the motorized lens , heater/blower etc. I would check with Q-see and make sure the power box provided will work with the PTZ camera in addition to the other 8 cameras.
Second I would check the cable being used. We CCTV Camera Pros have had issues with PTZ cameras and Plug-n-Play cables (pre-terminated cables)I would make sure you are using RG59 Siamese cable for the video and power of the PTZ camera.
If it is interference more commonly known as a ground loop you can use our Ground Loop Isolators.
I hope this helps.
