I've used both the RS and ms20. But prefered the rs pir because of power consumption. Now with the new power savings mods on the MS20 is there any compromise in PIR range using less power? Is everything else the same (hooked up) using Brians Board. I'm thinking about switching back to the MS20. Especially since my Local Walmart has them cheap and plentiful, and I'm not happy with my RS PIR distance on my most recent cameras.
