Mobile surveillance unit

A surveillance system, comprising:

• a camera at a first location, the first location being a fluid-handling site;
• a computer communicatively coupled to the camera;
• a sensor at the fluid-handling site configured to measure an attribute of fluid handled at the fluid-handling site;
• a modem at the first location communicatively coupled to the computer communicatively coupled to the camera and operative to transmit video information and the attribute of the fluid on a first network, the video information comprising one or more images captured by the camera;
• and
• a server system at a second location communicatively coupled to the modem via a second network, the server system comprising a storage medium storing instructions that, when executed, effectuate operations comprising:
• receiving, via the server system, one or more requests from a user computing device;
• and
• sending the video information and the attribute of the fluid to the user computing device,
• wherein:
• the server system is configured to establish and maintain a distinct session with each of a plurality of user computing devices, and to provide video information to each session from a common upstream feed received from the camera;
• the surveillance system further comprises a speaker and the operations further comprise:
• receiving, at the server system, from the user computing device, user instructions to issue an audible message comprising audio content created with the user device via the speaker;
• and
• transmitting, with the server system, the instructions to audibly emit the message with the speaker to the computer;
• the surveillance system comprises a light at the first location controllable via remote command from the server system at the direction of the user computing device;
• the surveillance system comprises a solar panel configured to provide electrical power to the computer;
• and
• the surveillance system is configured to detect an object in at least some of the one or more images, log a timestamp record of the detection in memory, and provide a report on the log to the user computing device.
