Hand-held image detector

The utility model relates to a hand-held image detector. The hand-held image detector comprises a display unit and a video input unit. The video input unit can receive the video signals of a network camera or a monitoring camera, which can be displayed by the display unit. With the hand-held image detector, the installation personnel of the camera can directly watch the real-time images shot by the monitoring camera or the network camera, and do not need to be communicated with management personnel in a control room via walkie talkies to repetitively adjust the direction of the camera when the direction of the camera is adjusted, and therefore the time needed for the adjustment of the camera can be greatly shortened.
