The invention discloses a multifunctional field infrared camera device. The device comprises a shell front cover, a shell rear cover, an outer box bottom cover, a GPS antenna, a WIFI antenna, a radiofrequency antenna, a COMS circuit board, a first optical lens, a second optical lens, a mainboard, a power panel, a front battery groove, a first lithium battery, a second lithium battery, a battery partition plate, a first solar cell panel, a second solar cell panel and a third solar cell panel. The camera device is provided with a space for installing the solar panel, the lithium batteries and amicrostrip antenna, an independent power panel is installed, and a solar panel assisted lithium battery power supply scheme is supported. The lithium batteries can be repeatedly used, so the camera is more environment-friendly; structures such as a glue stick antenna which is easily damaged are prevented from being mounted outside the camera, and the structure is stable; the single endurance timeof the camera is longer, and the use cost is lower; wireless communication is supported, and the timeliness of data is improved; and a special structure is arranged for accommodating the sensor, so the acquired environmental information is richer.
