Product Specifications Review: As ordered - As promised Review: It Works for old Swann - I bought this for my older Swann security system Model: DVR8-4900 which uses a power supply cord "CHANNEL WELL TECHNOLOGY Model: KPL-040F-VI" After this Power Supply burnt-out, my whole system was not working. I had hard time looking for this power supply, Swann website don't even carry it. Finally on desertcart, I found this "UpBright Model: HG-120500" Plugged it in and it works! The only problem I had was, which I do not agree with is that the seller charged me $15.89 for Shipping and Handling for a $9.99 Item. I thought it was too high for me being a Prime Member. No Worries, I still give it and the seller 5 Stars. ## Features - (Note: w/ 4-Prong Connector. NOT Barrel Plug end. Someone may have bought it by mistake.
