Type A - 50mm tube for inserting directly into the tube - most common for PTZ type cameras

Type B - comes with a circular base plate most common for dome type cameras (145mm plate)

NOTE - whilst we try to make the CCTV PTZ brackets as universal as possible, due to to the vast number of manufacturers and new models on the market, there may be instances where your specific manufacture or model of camera varies hence we recommend you check the technical drawing and dimensions PRIOR to purchase. unfortunately as we are not a CCTV camera supplier we are not able to offer guidance and advice on specific models and compatibility.

This is to fit a 76mm column which is industry standard size.
