1 cctv camera best one micromark are the best ones I have come across or a car reversing camera these are a little bit harder to focus with the lens you need to by.
2 a focusing lens on mine I have a 9-22mm Zoom CCTV Video Security IRIS Camera Lens
(260988582354) from china took 2 weeks to turn up
3 monitor I have used a 3 1/2 inch this has a function on it that allows you to turn the pic around and mirror or follow your camera very useful also has a cable to all recording or a second monitor does not have sound though so if you wanted sound you would have to make sure it was on the recording equipment
4 braket is made of a few different items so I have done a drwing of how I made mine it is below this post
5 if you are using the reversing camera you will need a 35 mm film case see drawing below if you are using cctv see drawing below
6 wire it up then adjust your bracket to until you get a clear pic the best way to do this is to turn the mag down on the scope and on the camera and slide it forward until you get a cross hair mine came in to focus about a inch and half away make sure the cam is pointing straight down the scope a little off to one side will give you a image but you will not be able to focus the pic or the cross hair together as one will be a slight blur and you will not get the range either. some of you will need to cover your faces fox for sure as the screen is quite bright and lights you you.
