Applies to all Network Cameras that have an "M" in the model number.
What the M12 connector is a 4 pin connector for mobile or rugged applications.
If you do not have a device that accepts M12, then you will need a M12 to RJ45 adapter cable. We offer this adapter with a part number of EP02-002261A (See picture below).
Since it uses only 4 conductors, the RJ45 uses only four pins. This means the power is going to be PoE Mode A. Which uses only 4 conductors, Pins 1,2,3 and 6 (See picture below).
Make sure your PoE injector or Switch is Mode A capable.
