I upgraded to a high definition DVR about a year ago. I don't have the brand and model handy right now. It is capable of running 2 HD cameras in addition to 14 regular cameras. It made a huge difference. I haven't missed a single plate passing the field of view, day or night. The DVR, HD camera, 3 additional regular cameras to supplement my other 11 and labor to install came to $1980. I'm not sure if all HD DVRs are this way but mine reguires very specific specs for the HD camera, only a few will work with it. I actually caught two idiots (meth heads) stealing the HD camera. They're both in jail. PM me if you want me to retrieve the make and model of DVR.
