Hello. If I have say 10 conditions and each one may fail, rather than have a try and catch round each condition, is there a better way where if condtion 1 isnt met, it ignores it and moves onto condition2?

Sorry, by condition its really checking for camera properties (using the image acquisition  toolbox).
I.e
Name  = src.DeviceName
Model = src.Model
Bin = src.BinningHorizontal
Etc. But sone of these properties dont exist for some cameras, so i currently surround then with try and catch.

Maybe something like this:

if isfield(src, 'DeviceName')
    Name = src.DeviceName;
else
    Name = 'unknown'; % or, just don't set the Name (leave off the else part)
end
if isfield(src, 'Model')
    Model = src.Model;
else
    Model = 'unknown';
end
% and so on...
