Low-power radio frequency network for a system of cameras

A system for transmitting images, the system comprising:

• a first camera configured to be powered by a first plurality of batteries, the first camera including:
• a first camera module including a first sensor configured to capture a first image of a first environment, the first image including a timestamp,
• an SD card configured to store the first image,
• a plurality of light-emitting diodes,
• a first display configured to display the first image,
• a first plurality of buttons associated with the first display, and
• a first communication module programmed to transmit the first image through a low-power communication network;
• wherein the first camera is programmed to:
• activate the first communication module to enter a wake mode,
• receive, during the wake mode, a heartbeat message indicating a period of time to be in a sleep mode,
• transmit the first image over the low-power communication network, and
• enter the sleep mode for the period of time;
• and
• a second camera configured to be powered by a second plurality of batteries, the second camera including:
• a second camera module including a second sensor configured to capture a second image of a second environment, the second image including a second timestamp,
• a second SD card configured to store the second image,
• a second plurality of light-emitting diodes,
• a second display configured to display the second image,
• a second plurality of buttons associated with the second display, and
• a second communication module programmed to transmit the second image through the low-power communication network;
• wherein, when in the wake mode, the second camera is programmed to:
• receive the first image over the low-power communication network,
• store the first image on the second SD card, and
• transmit the first image and the second image over the low-power communication network;
• and
• a home node configured to be powered by a third plurality of batteries, the home node including:
• a third communication module programmed to receive the first image and the second image from the second communication module over the low-power communication network, and periodically transmit the heartbeat message over the low-power communication network,
• a third display configured to display the first image and the second image, and
• a third plurality of buttons associated with the third display.

A system for transmitting images, the system comprising:

• a camera configured to be powered by a first battery, the camera including:

• wherein the first camera is programmed to:
• activate the first communication module to enter a wake mode,
• receive, during the wake mode, a heartbeat message over the low-power communication network indicating a period of time to be in a sleep mode,
• transmit the first image over the low-power communication network, and
• enter the sleep mode for the period of time;
• and
• a home node configured to be powered by a second battery, the home node including:
• a second communication module programmed to receive the image from the first communication module over the low-power communication network,
• a second display configured to display the first image, and
• a second button associated with the second display,
• wherein the home node is programmed to:
• periodically transmit the heartbeat message over the low power communication network, and
• transmit the image from the second communication module to an external device over a second communication network.
