Hi and Welcome to the Shack!
If your DVR has the ability to add an external receiver for the IR then that will be all you need.
On a side note, does your cabinet have lots of airflow inside as DVR's get hot even when not powered on so make sure you have enough air movement otherwise your risk damaging the unit or the hard drive may fail.
