Just watched your video... your DVR is capable of much better night resolution... you may want to try a higher quality Camera. I tried 120$ dome cameras... they work fine for up close (doorways/windows)... but when I replace the 2 cameras that view my driveway and mail box - I couldn't believe the difference. I can now clearly see someone across the street. The 152 LED cameras put out 10x better lighting. They light up everything evenly (not bright in the center and dark outside of say 20 degrees). Good luck catching your trouble makers.
