I have six SpyPoint cameras on my hunting lease. Five are four years old; one is a year old. None of the cameras dependably transmit pictures through cell service. Currently, none of the cameras are transmitting pictures. Calling SpyPoint’s customer service is terribly frustrating and useless. Hold times are horrendous. I was on hold for two hours last month. Each time I call, SP only offers to remotely reset the cameras, which is a temporary solution at best. I have been paying for the Premium membership and the cell signal at each location is good. Has anyone had a similar experience with SP? If so, have you identified the problem and found a solution? Has anyone had better luck with a different brand of camera?
