I used this 250ft mini RG-59 Siamese cable to extend the video and power lines for my Lorex analog cameras, and the run was plenty long for the far corner of my yard. The Siamese design keeps video and power together, so pulling one line instead of two made the install much cleaner. Signal stayed clear on my HD cameras with no noticeable interference. Only note: it comes as a bare cable, so you still need your own BNC connectors. Good pick if you are extending an existing analog setup.
