Dvr is HikVision DS-7204HVI-ST/SE 2X 600tvl cameras (entire net don't show any spec) 1x 480tvl sharp it's a cheap system for now. in the pic U can see my problem Sharp has a black bar on the right side on screen Share this post Link to post Share on other sites
Soundy 1 Posted February 12, 2012 What happens if you put the 480 on another channel, and one of the 600s on channel 3? Share this post Link to post Share on other sites
Six9siX-Joe 0 Posted February 12, 2012 Remains the same on every ch. the white cam is the first one I bought On the recorded D1 video also show that black line. Share this post Link to post Share on other sites
Soundy 1 Posted February 12, 2012 Does the line also appear if you plug it directly into a TV or monitor? I would suspect it's just a faulty camera... the effect has nothing to do with TVL. Share this post Link to post Share on other sites
Six9siX-Joe 0 Posted February 12, 2012 Yes. With that camera, there's always a black line, no matter where U plug it. I'm planing to buy another pair of cams but in my country I have a lot more choice of 420tvl than bigger tvl cams. The only reason I didn't do it yet is that black line. So if I get it right, every cam that is plugged in the dvr should be fully stretched on screen or not? Share this post Link to post Share on other sites
rory 0 Posted February 12, 2012 Its normal to have black borders from certain cameras on certain DVRs. Share this post Link to post Share on other sites
rory 0 Posted February 12, 2012 Its normal to have black borders from certain cameras on certain DVRs. at least in D1. Try 640x480 or less to maybe get rid of it. in D1 the DVR may be cropping it to 704x480 or the chip itself may do that. Either way, I see it all the time, varies between different chips and different DVRs. Share this post Link to post Share on other sites
Six9siX-Joe 0 Posted February 12, 2012 Than You for the info. I think I don't have the option to switch to 640x480 Here's some pic of dvr configuration Share this post Link to post Share on other sites
Soundy 1 Posted February 12, 2012 Yes.With that camera, there's always a black line, no matter where U plug it. Does that include plugging the camera straight into a TV or monitor? I'm planing to buy another pair of cams but in my country I have a lot more choice of 420tvl than bigger tvl cams. You're really not losing anything with 420 vs 480 vs 600. It may be a measurable difference, but not noticeable in most cases. NTSC video standard is limited to 480 vertical lines of resolution anyway, so anything over that is essentially wasted. The only reason I didn't do it yet is that black line. I wouldn't get hung up over that thin little line. As Rory says, it's probably a glitch you sometimes see with certain camera/DVR combinations. Or it could just be that one camera is faulty. Either way, it's not like you're losing anything. Share this post Link to post Share on other sites
Six9siX-Joe 0 Posted February 12, 2012 Does that include plugging the camera straight into a TV or monitor? Tv Yes. From the technical side maybe the lens mount is not centered on chip I'll try to fix it when I got time. Tnx all for the info. I just wasn't sure if this is normal for a low tvl cam.

Soundy 1 Posted February 13, 2012 Lens not being centered would not produce a straight, hard-edged line like that... if anything, it would be a curved, soft-edged area. My bet is still on a faulty camera. Share this post Link to post Share on other sites
rory 0 Posted February 13, 2012 Than You for the info.I think I don't have the option to switch to 640x480 Here's some pic of dvr configuration As mentioned its normal depending on the DVR and Camera. I first saw this with OEM Pano CCDs on GeoVision, since then also seen it with Sony HQ1 on another DVR, and other chips on other DVRs. Something to do with compatibility issue between camera chipsets and DVR chipsets. here is one example: viewtopic.php?t=12504 And some results from GeoVision tech support, which might also help explain your issue even though its a different DVR: viewtopic.php?f=36&t=12377 Share this post Link to post Share on other sites
