rx yes, but the tx?

"...Using a risco panel would wireless work at 100m?..."

As Norman pointed out, the panel doesn't dictate beams, I would add that were you to run four separate cable lengths of considerable distance between the panel and receivers you should double up on the power supply ( + and -), some just say the positive, but I disagree with this. Personally, I would tend to include a further boxed power supply adjacent to the four receivers, but that's just the way I do it as my preference.

"...Think I would rather stick with hard wiring myself especially with the distance involved..."

It would be to your advantage if you can locate a mains supply somewhere near the transmitters and run a boxed power supply from this source to power the transmitters. It might be worth taking into consideration the manufacturer's quoted distance of 100 metres, This is usually pretty reliable but consider the elements, fog, rain, hail, snow, and adjust the range as you think necessary. I tend to suggest about eighty percent of the stated range in order to compensate, although again this is personal preference. A cloudy overcast day is best for calibrating the units rather than a very sunny day.
