I have 4 ip cameras and I configured with ntp server, a 
Debian NTP Server. I am Having problems to synchronize cameras because I 
need at least 0.01 seconds of offset and I am having more than this 
value, as you can see in the graphic. Is very important that cameras 
time be very accuracy . Please help, is for an important project
I query cameras with this script

#! /bin/bash

dato=$(ntpdate -q $1 | grep ntpdate | grep offset | awk '{ print $10 }')

verifi=$(echo $umbral $dato| awk '{if ($1 > $2) print "ok"; else print 

if [ $verifi =  "ok" ]; then
echo "OK ($dato)"
exit 0
echo "Too much delay ($dato)"
exit 1

/ntp.monitor camera3
OK (0.003026)
