Step 4: Wire lengths - how far away from the DVR unit will your cameras be mounted?:
All cameras come standard with a 16-feet long cable. This is the typical length to get from the DVR to the windshield, or an outside mirror. But if you are going to mount a camera on the rear of a truck or RV that will require longer cables, you can add one or more 45' extensions ($10 per extended cable.) NOTE: THIS NOT PERTAIN TO ANY CAMERAS THAT ARE MOUNTED ON THE END OF A TRAILER WITH A DETACHABLE TOW HARNESS. That option is lower down on this form.
