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

    0 3/5 The Cheese - See all my reviews Verified Purchase(What's this?) This review is from: 6-15mm 1/3" F1.4 CS Mount Varifocal CCTV Manual Lens (Electronics) I can't really rate this, because it doesn't work on larger sensors. I have a sony a6000 and it can only be focused up close/macro. Infinity focus is not possible on my camera. I have other c mount lenses that work on the camera, but they aren't as wide angle, which I believe is the issue. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , August 29, 2015

    Great Deal

    0 5/5 alan - See all my reviews Verified Purchase(What's this?) This review is from: 6-15mm 1/3" F1.4 CS Mount Varifocal CCTV Manual Lens (Electronics) This lens is a great deal. With its manual zoom, focus, and aperture settings, it is perfect for the IP video camera I occasionally use to keep an eye out for visitors while I'm doing things in other places. This lens is a HUGE improvement over the fixed focal-length, fixed aperture lens that came with my video camera, and for the the price, it's a steal. It was shipped from Hong Kong, but the delivery time, considering, was surprisingly fast. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , November 28, 2012

    Great for what it is

    This is a quirky little lens that will give you unconventional but appealing results. I use it with my E-PL2. It is very fast and the focal length is very useful for m4/3. However, the results are pretty terrible by conventional standards. Sharpness is pretty good in the center but extremely poor towards the edges. There is considerable vignetting. At larger apertures, it is fairly smooth and pleasing (if you like the effect in general), but when you stop down (especially to f8, the smallest marked aperture) it has a much harder transition and I avoid it. The vignetting is much less at aspect ratios other than the native 4:3. With the large maximum aperture, you can get very narrow depth of field especially at close distances, and the bokeh is pretty crazy and swirly.The build of both lens and adapter is all metal, and while it doesn't feel particularly high quality, it doesn't feel too cheap either. The aperture and focus rings turn smoothly enough. Strangely... 5/5 Curtis Menton - See all my reviews, August 11, 2011

    Fun, Fast, Funky, with lots of Flare

    This Fujian 35mm 1.7 C-mount CCTV lens with Micro Four Thirds adapter is the best $35 I ever spent on a brand new lens.It's fun to use, if you enjoy manual focus lenses. The focus movement is smooth. At f/1.7 it a fast lens so it can be useful in low light situations. However, this lens is unpredictably prone to huge amounts of flare that often ruins the shot. I think it has 37mm filter threading so if you spent another $10 for a 37mm lens hood (I didn't) you might be able to avoid some of the conditions that make it flare. The filter threading does not rotate with the focus ring, so it looks like you could use a rectangular hood. Even so, that might not help. Closing down the aperture simply draws the flare into the center of the shot.The aperture is stepless, which could be useful for video on occasion. The aperture settings are not marked to a reference point so it's not easy to tell exactly what setting you're on. I scratched an aperture reference point... 3/5 Lincoln F.

    fun little toy lens

    0 4/5 akinaspeedstar - See all my reviews This review is from: Fotasy M2514 25MM F1.4 TV Movie Lens and Lens Adapter Kit for Olympus Panasonic MFT Micro 4/3 M43 Cameras (Electronics) Just received this in the mail today, and here are a few thoughts. the adapter plate is nothing to write home about but it seems well made and it connects securely to my GF2 and the lens attaches nicely to it as well.as for the lens... it's an absolutely awful lens that takes some fantastically interesting photos. i think it live up to its name as a toy lens. you wouldn't bring it to a serious photoshoot but you would always leave it in your bag to snap an interesting shot. the DOF is fantastic and the blur is really quite cool.i love playing with the manual app and the focus ring, you can see the iris opening and closing it quite cool.all in all i love this little lens it's now my go to lens when i just want to mess around. 0, March 7, 2012
