I have 8 DCS-930L all functioning indoors. I started noticing the cam closest to the router began to lose wifi signal strength measured in linksys router ddwrt firmware. Cams have been active for 10 months without any issues except for requiring occasional reboots. This camera was within 10 feet of the router monitoring dining room area and had a signal strength of -45 to -55 db while more distant cameras average -60 to -65 db all giving excellent video and mediocre audio at 500 kbs/sec upload.
Over a one week period the camera in question began to show readings of -60 to -65 db inspite of being the closest to router. After multiple troubleshooting steps moving the router around to increase the wifi signal it made no difference but camera continued to function. Then i noticed the LED red and blue wps light on and failure to connect. Even worse, the camera was HOT to the touch. The power adapter was more than warm. I unplugged let it cool it reconnected and fucntions but withing 15 mins it overheats and loses wifi.
This failed and was not reliable to leave in the cottage for fear of fire hazard. I returned it to Staples and received another new replacement.
Im not sure what to make of this but it leaves me uneasy knowing I have 7 other cameras and if I had not been at the cottage would it had smoked and burned my place down!. I researched overheating but found only one other comment losing wifi and overheating.
All other cameras continue to function and are not at moment overheating and there was no reason for this occur other than terrible hardware construction.
