Caddx Ratel Starlight HDR 1200TVL 2.1mm ND Filter Lens FPV Camera - Red

hello and welcome back to my RC channel I'm Andy RC and today I'm gonna be taking a look at the car X rattle fpv camera I've had a lot of requests to check this one out and this is the 2.1 millimeter lens version and it's got a ND filter if you don't know what an ND filter is it's like putting a pair of sunglasses over the camera's lens to put it simply and then the number is the strength of that filter and I think the reason that they have included that is this is a CMOS camera and CMOS cameras use a technique called rolling shutter and if you have a lot of vibrations and a lot of sunlight then you can get what is called shallow over the picture so if you reduce the speed of that shutter you will get less shallow and that's what an ND filter does it lets less light into the camera and that should reduce the shutter speed and you'll get less giallo so the voltage range is 5 volts 240 vo
