max recording for DVR and related analog TVL

Recommended Posts

Hi,

 

I had a small technical query.

I have read that using anything more than approx 300TVL with a CIF DVR is useless, as no matter how high the TVL of the camera the DVR would still do a CIF recording.

I just need to know - if I apply this concept to D1 recording DVRs, is there a meaning in using 1000TVL cameras? as we would only get a D1 resolution. So whats the max TVL for which a D1 DVR would be meaningful?

Am I wrong in any of my assumption? or am I missing something? Can you pl guide.

 

Thanks.

1000TVL camera which is not exist on the market. Actually, its 800TVL camera for utilized SONY IMX 138 + FH8520 ISP( china made).

 

You can record it by WD1(960H) DVR and it would be fine.
