With the growing popularity of the Samsung SDC-435 and SCB-2000 cameras here is a Tutorial of how to remove the factory fitted Infrared (I.R) Filter from these cameras. The In-built filters in Security cameras (and even some Video Astronomy cameras) have a cheap poor quality IR filter which is at the wrong Cut-Off point in the spectrum and will block out more than 30% of wanted light. The Samsung SCB-2000 & SDC-435 Camera's IR Filter comes out easily by undoing just 2 screws. HERE'S HOW:Step 1: pull off the top plate off the camera and disconnect the small cable connecting the Iris outlet- it is a push on connector, no latch- you just have to wiggle it back and forth a little. Step 2: Unscrew the two black screws in the front circuit board- they are screwed into plastic and take some effort to unscrew. That's it! Job Done The black plastic filter holder and the filter will fall out the front opening of the camera. Just put the case back together and you are ready to go. Here's what falls out the front (you don't need them but you may feel like storing them somewhere in a dark cupboard to be forgotten forever LOL! For Astro work you may want to add a proper high quality Imaging IR filter on the front of the nosepiece to prevent Star Bloat. Mostly for Refractor telescopes, especially Achromats. Probably not necessary for Reflectors and SCT's. These ones are very good: www.astronomik.com/en/photographic-filters/l-filter.html
