This invention refers to forest video monitoring. A distributed system for forest video monitoring and a method for fire detection implemented by it have been proposed. The system comprises: multiple video servers, with each video server maintaining at least one video camera; at least one object server; and multiple computer terminals. According to the method, such a video server is used to: receive video data from its video camera; analyze the video data in order to detect signs of fire; when detecting signs of fire, create a potentially hazardous data object related to the possible fire detected, with reference to the video data where signs of fire have been detected; and send the data object created to an object server. By means of any object server: the potentially hazardous data object shall be received; the potentially hazardous data object received shall be compared to potentially hazardous data object previously saved; based on results of comparison, the potentially hazardous data object received shall be saved at least once, at least one potentially hazardous data object previously saved shall be modified, and the potentially hazardous data object received shall be modified; and at least one potentially hazardous data object shall be sent to a computer terminal. By means of a computer terminal: any potentially hazardous data objects shall be received and submitted to the operator. The technical result involves arranging efficient data traffic and ensuring flexible management of computational resources.
