CCTV, Networking And Digital Technology

Creator: Vlado Damjanovski | Technology & Engineering - 2005-04-05

Different lenses have different MTF characteristics, depending on the quality of the glass, optical design, and application. For example, a photographic lens will have a better MTF than a CCTV lens. The reason for this is simple: the ...

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

    Amazing!!

    I have to say that I was not expecting much with this product - I mean, a lens adapter AND a lens for little more than the price of the adapter; however, despite some of the other less positive reviews here, I found the adapter to be of good solid quality. Heavy like steel as opposed to cheaper alloys. I found that it secured to the camera firmly with a firm click of the lens lock, and the lens screwed in and tightened as expected. I did not experience any looseness, and it held up for hours during a several hour photography session. The lens performs as advertised and provides surprisingly sharp images. The iris functions correctly, it is easy to step up and down with the f/stops, and it has a smooth manual focus.It is a very fast lens, which coupled with the Sony Nex's low light capabilities, churns out dark defying night shot images can can look very surreal. With respect to video capture, it provides a very different ascetically pleasing perspective with movies that... 5/5 Paul Incommendatus - See all my reviews Verified Purchase(What's this?)

    For the price, a must-have

    If you're on a budget and you don't own a 35mm prime lens, this little lens is a must-have! It's certainly not perfect, but it's surprisingly sharp.DIMENSIONS: 2" tall, 5.5" in circumference (basically 1.75" in diameter). In other words, ultra portable! My DSLR prime lenses are like 3x bulkierIDEAL AMBIANCE: Simply because you have to manually adjust the focus, I wouldn't recommend this for shooting moving subjects. It's best suited for still photography (i.e. portraits, still life) where you have all the time in the world to fine-tune. A monopod or tripod would be beneficial. If shooting a few feet away or closer, you'd ideally only care about one specific area of the subject in focus (i.e. a few petals from a large flower). The focus ring is by no means *difficult* to operate or unsmooth, but it does require you to exert more force than say, manually focusing on an EF-S lens.BUILD QUALITY: The lens itself is VERY solid--all metal/glass except for... 5/5 tightsandtea - See all my reviews Verified Purchase(What's this?)

    Pure Fun -- HIGHLY Recommended!

    This little thing kicks butt. For thirty-odd bucks, how can you wrong?! It belongs in every NEX (& M4/3) owner's kit.Pros:- Image quality is pretty dang good and totally belies its price. Get to know the advantages and shortcomings (see "cons" below) and work with its attributes and you can achieve some pretty awesome images.- Very sharp frame center; on par with either NEX kit lens (18-55mm/16mm) if not maybe even a bit sharper.- Super-small size makes the NEX closer to being pocketable. Also available for M4/3.)- Smoothly-damped focus and aperture rings.- Comes with adapter!- Wonderfully lightweight.- FUN to use. Brings the joy back into photography.Cons:- Doesn't stay screwed on to adapter very securely, especially when toying around with the aperture ring.- Build quality is...interesting (off-center numbers, unfinished metal parts, questionable calibration, etc.).

    Perfect for the Foscam FI8905W

    0 4/5 Mighty Mouse - See all my reviews Verified Purchase(What's this?) This review is from: Monoprice 107543 1/3-Inch IR F1.2 Fixed Iris CS Mount Lens with IR Correction, 4mm Fixed Lens for Other Cameras (Electronics) So I got the Foscam FI8905W with the built in 6mm lens. Found the lens to be too narrow so I ended up getting this 4mm lens from monoprice for $9. The install was pretty easy following the directions from youtube. What I found frustrating was after getting the focus right, when you tighten the focus screw, it messes up the focus again! So I ended up just having that screw loose enough so that I can easily refocus the lens before I close the front cover of the camera. I don't think it's gonna turn on its own in the future anyway. See the pics I have uploaded for a comparison on the view with the oem 6mm and this monoprice 4mm. Goodluck! 0, May 1, 2013

    Cheap and Good

This review is from: Monoprice 107543 1/3-Inch IR F1.2 Fixed Iris CS Mount Lens with IR Correction, 4mm Fixed Lens for Other Cameras (Electronics) Usually the combination Cheap and Good doesn't work but for this product it does.Lens is of a good quality and a cheap replacement for the useless standard Foscam FI8905W lens.It's just 2 mm (0.1 inch) short than the original but it's not a big deal as the video quality remains the same, just a very very small dark shadow at the corners. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , February 19, 2013
