CCTV Power Adapter, 2.0 A, 12 V DC, 5.5 x 2.1 mm Male, Male

This is not a standard CCTV adapter - this adapter has been specifically designed for the requirements of power-hungry CCTV systems.
Whereas standard adapters rarely provide enough power for use with CCTV, especially when using a splitter or a large camera, this 2 A adapter will supply plenty of power, with a maximum consumption of 24 W.
