A:AnswerThe range of the camera is completely dependent on your Wi-Fi signal strength. It's all tied to your router. The Blue system does have available signal extenders, but they appear to be close to useless (based on my experience). The cameras work great as long as your network signal's strong where the cam's installed and you have the upload bandwidth to handle multiple camera streams uploading at once.
