We start monitoring your cameras in the evening till morning for 12 hours. You are allowed to pick a start time and end time for a length of 12 hours. Our start-time ranges from 6 pm – 9 pm CST and end-time ranges from 6 am – 9 am CST respectively. So if you want your live surveillance monitoring to start at 7 pm CST then your shift will end at 7 am CST.
