grgo69 0 Posted June 22, 2011 Hy, I am looking to buy analog cameras and I have option 540tv or 650tv conected to standalone DVR. Now I wonder does it make any difference because it has D1/HD1/CIF recording resolution available. ? Also any sugestions welcome! Thanks, G Share this post Link to post Share on other sites
lely09 0 Posted June 22, 2011 It depends on the quality of the camera. If it is a cheap low quality camera it won't make a difference either way. If it is a higher end camera then you might notice some difference. Share this post Link to post Share on other sites
SEANHAWG 1 Posted June 22, 2011 After viewing the recordings, you shouldn't notice any difference at all in the resolution if they are basically the same camera but just different TVL. You may notice a difference pre-recording but I doubt it. There is alot more than TVL that makes a good camera, good low light performance, noise reduction, white balance, gain control, etc. all contributes to the overal picture quality.

rory 0 Posted June 22, 2011 Might notice a difference if the camera is plugged directly into a CRT composite monitor/TV, otherwise same pixel size on the DVR end (converted to digital) so same live and same recording pixels. Typically there is no difference between a 540 and 650 TVL camera when it comes to total effective pixels. Share this post Link to post Share on other sites
grgo69 0 Posted June 23, 2011 Would it make bigger difference if recording device would be comuter? Thanks, G Share this post Link to post Share on other sites
Soundy 1 Posted June 23, 2011 No. Both standalone and PC DVRs tend to use the same chips that actually digitize the video. Share this post Link to post Share on other sites
