Securame 0 Posted September 12, 2013 See a license plate 18 feet away recording at CIF resolution with a $30 camera? A D1 DVR would be a good start, yes. Go for 4ch D1 100fps or 8ch D1 200fps. WD Red hard drive is fine for a DVR. Hopefully with D1 and a 2.8-12mm camera at maximum zoom you can see something. Share this post Link to post Share on other sites
salvanost 0 Posted September 13, 2013 that's why i want to upgrade the system but i don't know where to start d1 100 fps? or 200fps? what brand? why not just 30fps? i knew people recommended minimum 30fps d1 cause some dvr not capable up to 30fps is it true? still lot's of bad d1 dvr out there? what minimum fps acceptable for d1? 15 fps maybe or 23fps? to preserve video filesize any recommended varifocal? or mine good enough for the task? cannot zoom too much from above pic, i still need to show the fence gate to see people coming in and out Share this post Link to post Share on other sites

If you want 4ch, it will be 100fps (25fps each channmel=, if you get 8ch, it will be 200fps. I am thinking PAL here since I do not know what country you are from, if you use NTSC, then it will be 4ch/120fps and 8ch/240fps. PAL is 25fps/channel, NTSC is 30fps/channel. If you want to see the full gate and also license plates on the other side of the street; I think you are going to have a hard time geting it right (I actually think you will not get it right, but hey, you already have the camera, so go ahead and try).
