antdickens 0 Posted September 29, 2004 Does anyone know of a link to some example video footage showing a day / night(mech filter) camera operating in both modes. Cheers Share this post Link to post Share on other sites
knightvision 0 Posted September 29, 2004 While I don't have a link, I will tell you I have yet to see one that works properly. The problem with a mechanical filter sliding in front of the CCD on a Day/Night, is that it actually changes the focal distance on the camera, thus distorting your image. As of yet, I haven't seen a lense that will automatically compensate for this, but have heard rumours that they are not too far off. Share this post Link to post Share on other sites
antdickens 0 Posted September 30, 2004 It looks nice there rory, what type of IR lighting are you using there? Share this post Link to post Share on other sites
rory 0 Posted September 30, 2004 At that time it is 1xExtremeCCTV UF500 IR Bulb, now there are 2 of them. It is also a 12mm lens setting. Share this post Link to post Share on other sites
rikky 0 Posted September 30, 2004 Rory, Which lens is being used on the camera? Share this post Link to post Share on other sites
rory 0 Posted September 30, 2004 cant remember off hand, its been about 3 years, its a 1/3". It was nothing special, not a special IR or Day Night lens, as they werent available back then (I think), probably this one as it is a 2.8-12mm Auto Iris lens, I maxed out the focal length to 12mm. I had a 1/2" Camera and lens first which went bad, so I switched it to the Sanyo Day Night High Res 1/3" and the picture was just as good as the 1/2". Obviously now I would use a specific IR Day Night Lens as they are everywhere now. http://www.tamron.com/cctv/prod/13vg2812assq.asp Ill go up to the camera next time Im there (tomorrow maybe) and take a look. One thing though, with the mechanical switch over to BW, it slides over, and with the glow from the IR, I had issues in the beginning where it would keep switching back and forth and then it got jammed, had to take it apart and fix it myself, then got it to work properly by just reducing the glare from the IR Lighting. Took the glare off the ground and higher up, the 2 LED Bulbs were causing too much glare being pointed in the same location, so one is now pointed slightly in one direction and the other is slightly the other, so that both light sources are not centered together.
