There are a number of topics on the web, about getting a modified version of motion (motion-mmcal) to work with raspberry pi v2.1 CSI camera.

A simpler method is to expose the camera interface through the standard video 4 linux kernel interface /dev/video0.

This can be achieved by simply enabling the video 4 linux kernel module and installing the standard motion.

Install motion

apt-get install motion

Enable the kernel module on boot

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

i2c-dev
cuse
bcm2835-v4l2

Load the module without reboot

modprobe bcm2835-v4l2

Start service as normal

systemctl enable motion
systemctl start motion

Raspberry pi 3 disable red and green lights

Disabling the lights on raspberry pi has been documented a number of times on the web.
If differs from model to model, however the following method just sets the brightness to zero and should work on all models.

Modify your /etc/rc.local too like the following

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

# Print the IP address
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
  printf "My IP address is %s\n" "$_IP"
fi

echo 0 > /sys/class/leds/led1/brightness
echo 0 > /sys/class/leds/led0/brightness

exit 0
