i agree , however the proof of that anythng over 640 TVL is misrepresentation ?
i know it has something to do with screen capability and digitising the signal in the DVR, BUT I DONT HAVE DEPTH IN THE INFO.
CAN U PROVIDE SUCH INFO?
It is confusing me now a days because many manufactureres are providing 700 tvl, 1100tvl , HD-SDI & AHD ...etc?
thank u
