pavouk Posted August 17, 2010 Report Share Posted August 17, 2010 I just installed this http://www.amazon.com/Vision-HTC35-Weat ... =de_a_smtd camera on my new 920bt. I'm having a big problem with the camera. Luckily I did "dry run" before I ran all the cables. I applied 12 volt to the camera and connected to Rear camera RCA. All I got was terrible dark picture almost no color, just little bit of blue hue almost like looking trough really bad and dark tint job. I also noticed that the picture had lines running across like the old CRT TVs when they were not tuned properly or wen you see one on TV. Is there a special requirement for the camera that is plugged to this unit? I tried to plug it in AUX2 with same result. Here are the specs on the camera: TV system: NTSC Effective pixel: 510*492 H sync frequency: 15734 kHz V sync frequency: 60 Hz Scanning system: 2:1 interface Sync system: Internal AGC: auto BLC: Auto Resolution 420 TV lines These are the specs on the original Pioneer camera: Power source ........................................... 14.4 V DC (10.8 V to 15.1 V allowable) Grounding system .............................. Negative type Max. current consumption .......................... 120 mA Output video ....................................... Mirror image (for rear view confirmation) Sensor ............................ 1/4-inch color CCD sensor No. of pixels ........ 492 (vertical) × 512 (horizontal) (Total no. of pixels: 270 000, effective no. of pixels roughly 250 000) Lens ........................................................Wide-angle, focal length f = 1.4 mm, F value 2.3 Angle of view ................... Horizontal: approx. 135º Vertical: approx. 105º IR cutoff filter (special filter for vehicle mounting) .................................................................. Provided Iris system .......................................... Electronic iris Scanning system ........................................ Interlace Synchronizing system ....... Internal synchronization Signal-to-noise ratio .......................... 40 dB or more (at the recommended intensity of illumination) Horizontal resolution ............ Approx. 300 TV lines The only difference is 300 vs 420 TV lines and scanning system does not have 2:1 mentioned Video out: 1.0Vp-p 75 ohm S/N ratio: more than 48 db Power 12V +-10% Any ideas before I send the camera back. Is it just incompatible or I had bad luck for bad unit? Thank you for your answers... Quote Link to post Share on other sites
VBLUE42 Posted August 17, 2010 Report Share Posted August 17, 2010 Is there a special requirement for the camera? Get a camera that is not a 35 dollar piece of junk. If you want decent quality you are going to have to pay for it. Most cameras for that price are garbage CMOS cameras. Of course it may just be defective but I suspect its because its cheap. Invest a hundred bucks and get a BOYO CCD camera. Quote Link to post Share on other sites
