A privacy-controlled care requester communication system includes a care-requester onsite monitoring and communication device and a cloud-computing server accommodating on-demand caregiver conferencing and vital stat alert capabilities. The care-requester onsite monitoring and communication device provides a closed-circuit visual and audio monitoring of the care requester's vicinity with specialized privacy permission rules that are set and adjusted by the care requester to achieve a personally-comfortable balance between health/safety risk monitoring and privacy considerations for a grownup patient. The care-requester onsite monitoring and communication device also enables either the care requester or the caregiving entity to initiate a “welfare check” webcam conferencing using the same care-requester onsite monitoring and communication device. Optionally, the privacy-controlled care requester communication system incorporates a care requester emergency bell device, a care requester wearable device, and environmental and/or vital sensors that can remotely measure the care requester's vital signs and environmental risk factors.
