No idea what you want them for and there is little detail on the specification, so even if you did say what you wanted them to do wrt DORI I couldn't tell you.
It appears to come with pre made cables, all the cameras that have come with pre made cables from what I have seen aren't usually up to much, but not familiar with the brand. Pre made cables also tend not to fair well if you upgrade the cameras at a later date either.
They appear to be inferring that the DVR is capable of handling 5MP but the cameras are 2MP ones.
SPRO website doesn't have these models on it as far as I can see, which suggests they may have been discontinued, 2MP kits are considered very old school nowadays, with 4/5MP being starting points usually.
2MP maybe okay for you, but no idea of what lens they come with or frame rates or how good the white light is or area you want covering, so a small terraced house going directly onto a pavement maybe okay, but the little back yard maybe not.
get a proper specification for what is being offered, then what you want to do with it wrt DORI, then we would have a better idea if they are good bad or a waste of time for you!!!
