Okay, in looking at the user manual for the NVR (which is rather difficult to decipher due to the broken English), I think your problem may be much easier to solve than I thought. This NVR has a +12 V auxiliary power supply available at the alarm port for external peripherals. The maximum current rating is 500 mA, well above the 150 mA for the LED light that I linked to in my prior post.remiss of me not to have included NVR details in my footer, I've updated this just now - it's an Dahua NVR 5216-16P 4KS2E
So all you may really need is the LED light. Connect the positive terminal of the light to the +12 V auxiliary power terminal, then the negative terminal of the light to a normally open (NO) alarm out contact. Then connect the "C" terminal paired with the NO contact to a ground contact with another wire. The NVR will then power the LED for you.
