Crystal Vision Premium DC 12V 5A Power Supply Adapter + 8 Split Power Cord For CCTV Security Camera DVR and LED, UL listed

works good on night owl security system. bought more cams(some different brands) on amazon & didn't have enough power supplies.this one is powering 8 cams & pic quality is great. only problem I've had is when I move the dvr around,some cams lose power & need the power connection wiggled around. might try a small amount of dielectric grease on them.great price, found this after i ordered another one(more costly) & it got lost by USPS. ordered from security mayor- fast shipping.

Works well, nice and convenient. No fluctuation of power.

Works perfect for my nightowl's camera
