Normally I do not post reviews and bother with such things but I absolutely had to share my story. I purchased this DVR 4 months ago. Installation was a breeze, as was the setup. We had a fire in the shop and almost everything was destroyed.... everything EXCEPT the DVR and the cameras we got. This is one tough cookie! Somehow it survived the intense heat and we were able to pull out the footage and gather the evidence to apprehend the arsonist that set the fire to our store!!
