Mounting a DS-2CD2347G1-LU turret camera to a DS-1280ZJ-DM21 Junction box?

Hi All,

Recently purchased a ds-2cd2347g1-lu camera and grabbed an eBay bargain for the junction box DS-1280ZJ-DM21. Was about to put it up but hit a problem.

Issue is the 3 outer holes (Marked on pic) don’t line up with the outer holes on my camera? Am I being stupid? Have I bought the wrong junction box (I am terrible at DIY lol )?

Thanks very much


Dan
