ibby 0 Posted May 16, 2011 HELP! Right guys, I have ran RB59 with a power source to the cameras. All the cameras work ok, but grainy image quality during the day and night. Can any one help? Share this post Link to post Share on other sites
Soundy 1 Posted May 16, 2011 More information is needed. Define "grainy". What cameras? What DVR? What resolution/quality/framerate settings? Still captures of the cameras, both day and night, would help. Share this post Link to post Share on other sites

OP: it's hard to tell from the tiny pictures, but honestly, those are cheap cheap CHEAP cameras, and grainy picture from them is to be expected. Share this post Link to post Share on other sites
Soundy 1 Posted May 20, 2011 And what does power have to do with it then? We haven't been told anything about what power supplies are in use, what power wire is used... how do you come to the immediate conclusion that it's insufficient power? I know you sell cheap cameras, so you won't want to hear this, but: yes, cheap products IN GENERAL are like this. If $40 camera weren't this crappy, there'd be no market for $600 analog cameras. So here's what the pictures look like, as much as I can tell from how small they are: they look like an image that's too dark - either because of a poor lens choice, or an imager with poor sensitivity - being electronically boosted to provide a brighter picture, with inherent electrical noise being boosted along with the image. Exactly as one would expect with cheap cameras. Share this post Link to post Share on other sites
rory 0 Posted May 20, 2011 Daytime looks okay? Night time, its staying in color, the cheap Color IR cameras i sometimes sell switch to BW at night no matter what but then they are all different. Dont expect anything more from cameras that cheap with IR, they are what they are. Share this post Link to post Share on other sites

In the clear picture the sun is more overhead giving lots of light. In the grainy picture the sun is starting to go down but there should be plenty of light there for a good camera.

Soundy 1 Posted May 20, 2011 You first. i am shame to show my cheap products. yours are so good. what? you afraid to show? It's not relevant to the thread. Plain and simple: OP's problem appears to stem from using cheap cameras with poor sensitivity. Deal with it. Share this post Link to post Share on other sites
vin2install 0 Posted May 20, 2011 Looks like the grainy picture at night is coming from the AGC kicking in at night. And maybe too much light around and the camera isn't sure if it is in night mode or not. Share this post Link to post Share on other sites
