1 . A method of operating an optical monitoring device mounted on a Heating, Ventilation, and Air Conditioning (HVAC/R) system, the method comprising:
measuring a temperature inside the optical monitoring device;
determining whether the measured temperature is less than a predefined threshold temperature;
in response to determining that the measured temperature is less than the predefined threshold temperature, establishing, by the optical monitoring device, a wireless connection to transmit at least one image, to be captured by a camera;
in response to receipt of a trigger, capturing, by the camera, the at least one image of a sight glass of the HVAC/R system; and
transmitting the at least one image over the wireless connection.
2 . The method of claim 1 , wherein the trigger comprises one of a manual trigger received via an application or an automated trigger received from a controller.
3 . The method of claim 1 , wherein in response to determining that the measured temperature is more than the predefined threshold temperature, the method comprises reporting an abnormal operating status of the optical monitoring device to a controller or a remote application hosted on a user device.
4 . An optical monitoring device comprising:
a housing comprising a first compartment; and
a processing unit configured to:
determine whether a measured temperature is less than a threshold temperature; and
