Yes, it is possible to use a multi-camera power supply box with pre-made Siamese coax cable that already has the male power plug end attached. You can simply attach PT-3 female power lead to the end of your existing cable.
This turns the 2.1mm plug into a positive and negative cable lead that can attach to the screw terminals of a power supply box for your security cameras.
Please let me know if you have additional questions about this.
