I purchased this on Amazon, Canecho monitor system model cm00-r000902, asin b00m979ul2 @ $69.99 and extra long cord set hx-rd10m, asin b00dvzycms @ $10.95. Note that the 0's may be o's. Works well. You need to supply 12 volts to both units so they are not truly wireless and I used an magnet I removed from an old speaker and mounted this on the camera so it could be relocated if needed. Amazon has many camera systems available an the price ranges from low as this is to pretty pricey. The wireless term is for the small controller that I really don't use. There are other posts here regarding these systems others have installed so do a search and get some idea's. Best of luck, Bob
