Hough Transform for line detection in video

Hello!

I need to determine movement of a wire accross my video. I found Hough transform useful for this applciation and managed to detect the line of interest by tuning the houghpeaks and houghline parameters. Due to orientation of the wire with respect to image origin I had to tilt the frame 90 degree in order to detect the wire! I attahced a photo from the line of interest

I am facing with two problems now:

1) the hough transform is keep detecting irrelevent boundries of the image frame as the top 3 peaks which for that I had to use the command of max_len to detect my line! Is there any way that I can blur this area ,or is there any way that I can restrict the searching domain of hough transform ?

2) As my intention is to use hough transform to detect this line across the entire video frames considering each frame has its own brightness, edges, and objects (the video has a dynamic background and the background features changes repetedly throughout the video ), I am really wondering if Hough transform is a suitable appraoch to do this task

I have attached two photos, I appreciate any help in advance
