The invention relates to a video monitoring information transmission device for a power tower and belongs to the field of monitoring. According to the video monitoring information transmission device for the power tower, a 3G wireless internet access module is arranged in a monitoring camera; a remote monitoring center is connected with a public Ethernet network; a monitoring camera system transmits video monitoring information shot by the monitoring camera to the remote monitoring center by a 3G wireless network; a WIFI (Wireless Fidelity) communication module is arranged in the monitoring camera system; and the monitoring camera system is networked with mobile terminal equipment on the ground near the tower by a WIFI wireless network. The video monitoring information transmission device for the power tower adopts a 3G wireless internet access manner to log in the public Ethernet network to implement complete isolation of data transmission from the public network and has high data safety; the maximum integral transmission image supported resolution can reach the D1 standard and the requirement for timeliness of remote monitoring is met; and perambulating personnel can conveniently extract and acquire monitoring video information of the power tower in days, which is stored in the wireless monitoring camera system, without climbing up the tower to operate. The video monitoring information transmission device for the power tower can be widely used for the field of monitoring and management on a power overhead line and the tower.
