This is our reversing camera voltage regulator cable/dropper. If you wish to use a 12V reversing camera (most common) and you either have a 24V vehicle, or you wish to reduce the risk of damage from voltage spikes from alternators/solar panels, then simply insert the plug of this voltage regulator in to the 2.1mm/5.5mm DC socket (most commonly used) on your reversing camera, and provide upto 24V power to the red wire, and earth the black wire.
These have an EMC certificate (see photo). We obtained this because we had a customer buying 500pcs at a time that required certification due to where they were being used. We have reduced the price of these because the customer's business eventually failed and we were left with a large quantity.
From one of our highest rated factories, the quality in your hand is self evident. So grab a bargain.
