wildextreme 0 Posted January 18, 2006 I HAVE A 36 LED IR CAMERA WITH A SHARP CCD CHIP AND 420 LINES OF RESOLUTION. WHEN I VIEW THE CAMERA AT NIGHT THE IR LIGHT LOOKS LIKE A NARROW BEAM OF LIGHT SOMETHING LIKE A SPOT LIGHT / FLASLIGHT EFFECT. IT DOES NOT REALLY COVER A LARGE AREA DOES ALL IR CAMERAS LOOK LIKE THIS? Share this post Link to post Share on other sites
securitymonster 0 Posted January 18, 2006 yes, you will typically get this affect with built in infrared. You can always add an external infrared shooting at a different angle and that might help. The infrared also needs to reflect and bouce of things, so if there is nothing to "bounce" off, then you won't get much IR coverage. Alot of the members here understand IR technology really well. They will correct me if I'm wrong plus give you lots and lots of information. You might try searching the site too as this comes up alot.

securitymonster 0 Posted January 18, 2006 This is defenitely a DIY/Budget Camera but I personally deal with these types of cameras alot. The camera will do "OK' for what your looking for. Generally the more infrared, the further you will see. When it says that its a Day/Night, it will digitally switch to Black and White at night which will give you a grainy picture. It will also be very very sensitive to light at night, so if you have any lights in the area that the camera can see, you have a potential problem of "whiting" out the picture, and it can be so white that you can't see anything! Tell us what your going to be watching and that will help. When you install the camera, treat it like your taking a photograph. You wouldn't take a picture of some kid running with the sun looking direclty at the lens! Share this post Link to post Share on other sites
