SEANHAWG 1 Posted September 9, 2011 Hi Rory, Do you think it has to do with the bigger TVL cameras getting distorted when moved to a smaller screen size and that is possibly why the smaller TVL cameras are staying fine? Share this post Link to post Share on other sites
tomcctv 187 Posted September 9, 2011 I thought the Monalisa was made exclusively for CNB. I am almost positive I read that somewhere. hi. yes the chip is CNBs sorry i ment using the camera on another make of DVR. we run CNB on cms and dont see this problem Share this post Link to post Share on other sites
HTElectrical 0 Posted September 9, 2011 No problem, I would just like to know why they are doing that. Share this post Link to post Share on other sites
rory 0 Posted September 9, 2011 No problem, I would just like to know why they are doing that. its only happening to the Monalisas out of 40 odd cameras from several sites, so most definitely they are the issue, regardless of what PSS does to the image. I will connect in my custom app and try them, see how it goes resized down. Share this post Link to post Share on other sites
HTElectrical 0 Posted September 15, 2011 CNB contacted me this afternoon and said "they do not have any problems with that camera not switching to Night mode". I told them Ya right!!!!! I am going to contact DWG and see about an RMA and maybe a different camera. Here is a night pic using a 100W halogen in the far upper right hand corner. It wouldn't be that bad if it could accomplish that image with no extra light, like the Mintron. Share this post Link to post Share on other sites
HTElectrical 0 Posted October 12, 2011 Well this is what it looks like in the exact same position same light etc.... CNB sent it back to me after I sent it in for warranty and I quote We checked out the camera and we found that the Day/Night function was on Color. We initialized the product and all functions are working fine. If that is fine than CNB really SUCKS! Mintron camera for comparison. Share this post Link to post Share on other sites
shockwave199 0 Posted October 12, 2011 Apples to oranges. You're comparing a 200 dollar camera to a 600 dollar camera. Sorry, but you got a 200 dollar lesson- don't buy this camera. Shame you couldn't return it, or can you still? That mintron looks excellent. If it wasn't so much money I'd surely get eight of them myself. You can try cheaper cameras and maybe find one comparable to that mintron in those lighting conditions, but it's a crap shoot. Buy with a return policy. Good luck.

tomcctv 187 Posted October 12, 2011 Well this is what it looks like in the exact same position same light etc.... hi. never had a CNB as bad as that. BUT i would say it is a setup problem. you cant compare those two images as the lighting is not the same in both images. CNB you have the extra lighting infront of the camera and on the Mintron you have it behind the camera Share this post Link to post Share on other sites
mike_va 0 Posted October 12, 2011 I am going to try a new Mintron Dome camera that has similar specs to the one I am using. So far, for the price, I haven't found a better camera. 83SR10HN-VP-VF 83W7N-VF-VP In fairness, it seems this mintron is default 4x sense up? That would make sense with 0.0014 --> at no sense up that is ~ 0.006 probably at 30IRE which is possible at least, still sounds a little optimistic. I have played with some 1/2" Mintron B&W though that are pretty amazing... Share this post Link to post Share on other sites

rory 0 Posted October 12, 2011 they do rory. you cant buy the monalisa in the uk. The issue is the Monalisa chip. Problem is, on CNB's site everything is Monalisa now. Share this post Link to post Share on other sites
shockwave199 0 Posted October 13, 2011 How did you come across that Mintron camera? I cant find them available for sell anywhere. Found that exact model earlier today. It was 495, a hundered bucks off of list. Type in the mintron with that exact model number to search and you'll find it. Share this post Link to post Share on other sites

CNB you have the extra lighting infront of the camera and on the Mintron you have it behind the camera Ah yes I can compare those 2 images. The CNB is mounted 1 foot below the Mintron and the image was taken at the same time for both cameras. Share this post Link to post Share on other sites

Dan Actually, suggested retail for that camera is 360.00, and that is only because it is a 22X optical zoom camera, which does not make the image any better than the CNB, just enables it to zoom in on farther objects.

SEANHAWG 1 Posted October 14, 2011 the image was taken at the same time for both cameras. Are you sure? It appears the light for the garage is on on the CNB pic and the Mintron is obviously not. Share this post Link to post Share on other sites

SEANHAWG 1 Posted October 15, 2011 oh yeah, your right. Dang. I agree that Mintron looks excellent. The only thing about those CNB's is they dont switch to B/W very easily. I would bet that picture would be alot less noisy if it was in B/W mode. II would bet that since its not in B/W mode that the IR filter hasnt slid out of the way either which makes it look even more poor. I have some cameras that switch to B/W actually too easy and I have to turn the Day/Night setting almost all the way down to prevent it. Sometimes with CNB, you have to turn the Day/Night all the way up to make it switch and that even isnt enough sometimes. Share this post Link to post Share on other sites
rory 0 Posted October 15, 2011 Problem with those 24VFs is they dont use a photocell. their video switchover sucks. Share this post Link to post Share on other sites
HTElectrical 0 Posted October 15, 2011 Here are a couple of images of the Mintron 83W7N-VF-VP Share this post Link to post Share on other sites
mike_va 0 Posted October 15, 2011 The datasheet I found implied the Mintron runs at 4x sense up (slow shutter). Can this be disabled? If this is at 4x sense up it would not really be a fair comparison. For example, two pics - one at nominal, one at 4x sense up. The fence in the background is only visible with the 4x.

HTElectrical 0 Posted October 15, 2011 Yes, you can disable the sense up, but why would it be unfair? The image is great, the video is smooth, not choppy, and you can get a better color image than most black and white cameras can provide. Share this post Link to post Share on other sites
SEANHAWG 1 Posted October 15, 2011 but why would it be unfair Because at slow shutter speeds you tend to get some motion blur on fast moving objects. On most applications that camera would be fine but on some it would not such as trying to capture moving vehicles and such. Nonetheless, its still a great looking image compared to other cameras I have seen with the same type of shutter settings. Share this post Link to post Share on other sites
