About this book
Closed circuit television (CCTV) is experiencing a leap in technology using digital techniques and the Internet. The new edition of this high-level professional reference retains the particulars that made the first edition a success, including the details of CCD cameras, lenses, coaxial cables, fiber-optics, and system design, but it is expanded to cover all video compression techniques used in the ever increasing assortment of digital video recorders (DVRs) available on the market today. It also serves to clarify the technology of data networking. The theoretical section explains the various compression techniques, such as MPEG-1, MPEG-2, JPEG, Wavelet, H.261/263, JPEG-2000, MPEG-4, etc. Networking is also a new and unknown area for many CCTV installers and this is explained in a brand new section.The challenge of selecting the right system from such a wide variety of new technologies available in CCTV has been compounded by the advent of DVRs. This new edition of the book CCTV demystifies DVR technology.- Covers brand new digital video recorder (DVR) compression techniques, image quality, measuring and networking- Fully illustrated with dozens of photographs, tables, checklists, charts, diagrams and instructions- Encompasses CCTV standards for U.S., Europe, and Australia

    Great alternative to buying replacement cameras

    The stock cameras that came with my Z-Modo 8-channel CCTV system had a very narrow field of view and I really wanted wide angle cameras to cover more areas of our property. Replacing the cameras would have been quite expensive, so I decided to try lens replacement first. Changing the lenses was very easy, a simple screw-out/screw-in operation. Sometimes the spring had to be discarded in order to be able to screw in the lens enough to get the image in focus, but this was only a problem the first time it happened (took some fiddling before I figured out that the spring was fully compressed and was preventing the lens from being screwed in any further). There was some IR light bleed into the image due to the wide angle of view (mentioned in some other reviews); I took care of this by cutting short sections of black conduit that fit around the lens to block the IR light. Other reviewers used black electric tape, but since I had some thin conduit handy I just went with that... 4/5 M. Villasin - See all my reviews, January 16, 2013

    Nice lens, good idea

    0 5/5 Physicstech2 "PhysicsTech2" (Oregon) - See all my reviews Amazon Verified Purchase(What's this?) This review is from: Board Security Cctv Camera Lens with 2.6 Mm Focal Length (Electronics) These little lenses are a great way to upgrade a standard security camera to better fit the needs and coverage you need for that camera. I needed to upgrade two 50 degree standard cameras to cover an area that needed about 120 degrees of coverage.Two of these cheap lenses and about 10 minutes with a #1 jewelers screwdriver did the job. Once the lens is installed, you connect the camera to your system and adjust focus - so, hopefully you have a spare cable to use for that. Other than that, it is a piece of cake! They may be listed as for 1/4" or 1/3" cameras - I used both types on my 1/4" camera system just fine. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , March 10, 2013

    40-45 Degree Viewing Angle

    I purchased two of these lenses to replace the factory lenses that came with my Foscam FI8910W IP cameras in hopes of gaining a wider viewing angle. The lenses I received were a perfect physical replacement for the Foscam's factory installed 3.6mm (67 Degree Viewing Angle) M12 circuit board style mounted lens. However, the 2.8mm lenses that I received from seller "uxcell" have a narrower field of view (40-45 degrees with a focal length of approximately 6mm) than the factory 3.6mm Foscam lenses.I purchased two of these 2.8mm lenses and tested them both just to be sure and yup, something is definitely wrong here. The lenses shipped to me were advertised, packaged, and shipped with a protective lens cap all indicating that they were 2.8mm lenses. (I'm uploading a few photos of the lens and packaging.)

    No bueno...

    0 1/5 Amazonian - See all my reviews Amazon Verified Purchase(What's this?) This review is from: 3.6mm 92 Degree Wide Angle CCTV Camera IR Board Lens Focal for 1/3" CCD (Electronics) Bought this lens to replace the 6mm lens that came with one of our Night Owl cameras. It's easy to screw in at first, but then gets very difficult. The barrel ended up being too short, so by the time it was screwed in far enough to barely start being able to get any kind of picture, the glass inside had already started cracking. As my wife, who was inside monitoring the picture on the TV, kept saying a little bit more, the glass cracked into a million pieces at both ends. Then we had a hell of a time getting it out because it was screwed in so tight, and ended up damaging the ccd on the camera itself in the process, and now have to replace it. A $6 piece of junk now caused us to have to spend another $99 on a new four pack of cameras. It was either that or replace the cameras at $39.99 a pop.

I would need to crop my shots to use them, and quite honestly this lens is a little too funky for my tastes... if you're willing to crop your shots and can do something creative with the extreme swirling at the edges, then you might get some use out of it.
