According to the spec sheets these two mounts are exactly the same, it's just the -TRL version has an adapter plate with it. Some cameras will fit without the adapter plate but others need it because Hikvision changed the size/layout of their some of their camera mounts/hole positions ever so slightly. Why have one standard when you can have many
We would definitely recommend going with the bracket that is stated as compatible on the camera's spec sheet, although the measurements may look exactly the same for 2 brackets the measurement diagrams they provide do not include every measurement and some measurements only have to be millimetres out for the camera not to mount to the bracket.
