Please log in for more thread options CCD night cameras have the IR LEDS right on the camera. Do these cameras have anything special about them that makes them work well with IR illumination (do they have circuitry to switch to B/W etc). The reason I ask is that I would prefer to use standard CCD cameras and a separate IR illuminator, and am wondering if they will work together properly. Thanks. | |||||||||||||||||||||||||||||||

Please log in for more thread options @n51g2000cwc.googlegroups.com: You need to make sure the cameras do not have an IR cutoff filter. Being color, they most likely do. But check to be sure. If they don't have one, then they will work. If they do have the filter, you will need a LOT more IR to make it work.

Please log in for more thread options Unless you have a real need for obscurity, there's a much simpler (and usually
less expensive) approach to covert CCTV. Speco makes a standard motion detector light with two flood lamps that come on for a couple of minutes any time someone walks by after dark. Most people are so accustomed to seeing these lights that they don't give them a second thought. What the subject won't know is that there's a camera mounted inside the motion detector. One advantage of this approach is that you'll get a much better, more detailed image with white (well, close to white) light than with IR. Another advantage is that when most people trigger those lights the first thing they do is look up directly at them. This will give you an excellent chance at recording the person's face. I might be a little biased in favor of Speco since I sell it online. However, I've used their cameras with good results on several of my own installations. -- Regards, Robert L Bass =============================>

Please log in for more thread options Thanks for the answers, that was quick. Looks like a had better not
assume the camera will work with the illuminator, and had better check it. Just to elaborate...I'm trying to keep a sleek look on the house with no wall mounted lamps etc. I don't even want a small IR dome camera sitting under the soffit. I'd like to use bullit cameras and just have the tip sticking through a small hole in the soffit. Otherwise I'd use wall mounted motion lamps, or purpose-built IR daynight dome cameras mounted under the soffit. | |||||||||||||||||||||||||||||||

The other issue will be the illuminator. Anything powerful enough to give good video from more than a few feet away will require a fiarly large IR array. One of our vendors, Extreme CCTV, has a very informative website. They make a wide assortment of cameras and IR illuminators. Their hardware is about as good as it gets in this industry. Prices are not cheap. Here's their URL. I think you'll find it an interesting browse. There are sections of the site dedicated to IR illuminators, cameras and combination camera/illuminators. Being mostly a commercial / industrial CCTV maker, many of their products will your aesthetic requirements. If the range is satisfactory, you might want to consider their WZ series day/night cameras. http://www.extremecctv.com/products.php?producttype_id=10&whichpage=1 I mentioned Speco in an earlier post. In addition to "covert" cameras, they make a number of bullet style cameras. One which you might find interesting is the HT-INTB2. This is an "intensifier" type of camera, designed for extremely low light operation. URL follows: http://www.specotech.com/cart/products/productDetails.asp?prodID=881 These are just a couple of examples. There are lots to look at. Let me know if I can be of assistance. -- Regards, Robert L Bass =============================>
