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

    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.)

    Reasonable manual lens for great price

    Update: Lens seller contacted me and very politely asked to consider giving a better review. So I added one star (truth in reviewing). The reason that I upgraded my rating is that my initial reaction was on the tail of having played with $300-$500 lenses. Not really fair. My update thus includes that fact that for less than 5-10x the price of a mainstream lens you get a lens that has some unique characteristics that might be useful in many types of photography.The lens is well-made, metal lens barrel & hardware, comes with end caps, and has coated lenses. For $26 dollars the lens is a good deal DEPENDING on your expectations. Having spent more time with it, I believe these are probably made for automated visual inspections. Focus and F are manually controlled and continuous (no click stops). There is a filter thread that appears to be 37mm BUT a standard 37mm filter does not fit - it would be nice, if this were a standard thread.Limitations:This lens... 4/5 beikokunotora "beikokunotora" (Dallas, TX United States) - See all my reviews Verified Purchase(What's this?)

    Zoom for Lorex

    0 5/5 James M - See all my reviews Verified Purchase(What's this?) This review is from: CCTV Security Camera 16mm Focus Length IR Board Lens (Electronics) Zoom for the Lorex system LHV828 camera LBV2521.No need for another camera now. This lens worked for 80 to 100 ft person ID! With 16mm it gives about a 4x zoom on this system and camera. It could read a license plate in daylight at 100 ft and a person filled half of the screen height. Just remove the glue with a drop of carb cleaner, screw out the old lens and screw in the new one until you get focus. I also ordered 12mm and 25mm to experiment more. That 12*.05mm thread is a key requirement for this camera.Jim 0 Help other customers find the most helpful reviews  Was this review helpful to you? , July 18, 2015

    0 2/5 Jonathan Cunningham - See all my reviews Verified Purchase(What's this?) This review is from: SainSonic 35mm f/1.7 CCTV Cine Fujian Lens for Nikon 1 Camera (Electronics) Not a big fan of the focus range on this lens, I used this with my Black Magic Picket Cinema Camera and I expected to be able to focus on things that weren't just 3 to 7 feet from the camera. The lens only really seems to work at those distances and only when the aperture is closed down. Over all this lens is pretty impractical and rather difficult to find a purpose to use it for. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , June 11, 2014

    OK for $25, weird surreal bokeh

    0 3/5 beikokunotora "beikokunotora" (Dallas, TX United States) - See all my reviews Verified Purchase(What's this?) This review is from: SainSonic 35mm f/1.7 CCTV Cine Fujian Lens for Nikon 1 Camera (Electronics) For $25 dollars I cannot complain. However, be aware that this lens does not allow infinity focus on Olympus PEN E-PL5 with Photodiox C-mount adapter. This lens does not appear to be as good as the 50mm from the same company - at no F or focus distance did I feel that I got a tack sharp focus. Contrast is low and flaring is evident (probably would help to attach a hood) The bokeh at F1.7 is actually a bit disturbing but in a surreal sort of way - this is definitely a "special effect" lens. I probably won't use this one very due to the often BUT for $25 not worth the hassle of returning. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , July 16, 2014
