chief_lam 0 Posted November 14, 2012 So I recently installed a new dome camera and then someone broke into my fiances car the other night. The suspect was driving that car and its not really a great shot. The camera is having some digital noise issues and is not really clear at night. I currently have the CMD3270DW Dome camera from LT Security. It appears to have some digital noise issue and I sent tihs picture to a LT tech support, they asked if I was using a 12 volt line and I said yes. They told me to switch it to 24AC and it should solve the problem. What do you guys think? Maybe try a different camera? Here are the specs. •700 TV lines resolution •1/3" Pixim "Seawolf" sensor •2.8~12mm varifocal lens •17 pcs IR LEDs •Wide Dynamic Range(120dB WDR) •Advance 3D noise reduction (3DNR) •Auto Tracking White balance (ATW ) •Built-in OSD •ICR (IR CUT) •DC 12V & AC24V input •IP 66 •Vandal proof ^Screenshot of suspect ^Actual shot of monitor Share this post Link to post Share on other sites
justincameras 0 Posted November 14, 2012 (edited) That looks more like reflections on the dome or lens. IR cameras suck when they turn to BW. The IR has limited range and true forensic detail cannot be achieved unless they happen to be walking 4 ft away from the camera. Widening the field of view as you have lessens detail.

chief_lam 0 Posted November 14, 2012 That looks more like reflections on the dome or lens. Right, the dome is a little dirty. However you can see the big horizontal noise on the bottom and top. Share this post Link to post Share on other sites

Any electrical sources near the camera's cable? Parallel A/C cable? To troubleshoot, the cheap choice is 24 volt power . Share this post Link to post Share on other sites

There's an exterior light by the camera, but when the lights off the noise is still there. I'll try the 24volt perhaps then, but I'm still not really impress with the night quality though.

BestGear 0 Posted November 14, 2012 It does look like you have a dirty dome (as said above) and the IR is reflecting off that, softening the image. Oh...and some other noise! BG Share this post Link to post Share on other sites
justincameras 0 Posted November 15, 2012 Try one of these. Radioshack about $10 Also, is her driveway light flourescent? These are 12 volt power's nightmare. Share this post Link to post Share on other sites

justincameras 0 Posted November 16, 2012 It's a ferrite magnet you snap on the power, CAT5, wires. It is supposed to "filter" noise from unwanted induced power. http://en.wikipedia.org/wiki/Ferrite_bead http://www.radioshack.com/product/index.jsp?productId=2103222 Share this post Link to post Share on other sites
