I have 3 IP cameras configured in Motion running on a Raspberry Pi
(Ubuntu).? These cameras all use MJPEG streams and the CPU utilization
on the Pi hovers around *50%*.
I added another camera which doesn't support MJPEG, but does support
RTSP.? Adding this one RTSP camera ran the CPU utilization up to around
*200%* (I believe this Pi has a quad-core CPU).? Is this typical for
RTSP?? Is there any way to reduce the load for this protocol?? I want to
add several more cameras but cheap wireless outdoor IP cameras that
support MJPEG seem to be hard to come by nowadays.

What is the resolution of the mjpeg cameras and what is the rtsp one?

Also what is frame rate of both?

The resolution of the MJPEG ones are all 640x480.? The RTSP one is 720p.
I have /framerate/ set to 15 in motion.conf.? The individual camera
config files do not have that setting.
