I am building my second camera now using the Mainstay wm2 sensor. My first was with the RS pir. I noticed the modification plans for each required different relays. Can you use a reed relay in the wm2 like you use in the RS pir? I like the fact that they are so quiet and cost about the same. This is a question for my next cam (the wife is loving me!). I already have a regular (?) blue box type relay in the wm2 sensor I'm building now.
