As I mentioned, the receiver is very sensitive to ambient light and definitely needs an enclosure. My initial R&D shows that a workable, down & dirty, interim solution can be made from the black plastic cases (cannisters) that a single roll of 35mm film comes in.
I cut a square hole in the bottom of the case, slightly off center (let's call it "toward the rear"), just large enough for the metal part of the USB connector to fit through. There is enough distance between the bottom of the Remote Receiver and the cable hood for this to push through without interfering with the connection.
I then put the top on the case (before inserting the remote) and cut a 15mm slot halfway around the "front" of the cannister at the level of the IR sensor.
With this setup, the circuit board sits somewhat more toward the "rear" of the cannister rather than in the center, and is therefore more shaded and fits without wobbling if all your cuts are accurately done.
I wrapped the cannister with a strip of 2 inch transparent packing tape just below the top. This covers the slot, gives a degree of weather proofing and helps strengthen the cannister.
It was then a simple matter to slip the receiver onto the cable and re-snap the top. With the receiver installed, I get excellent coverage by the remote transmitter, far fewer false positives from daylight, and protection for the circuit board.
HTH,
