CCTV and CCTV Security Tester

With the development of science technology, CCTV (Closed-circuit television) system becomes more and more popular. Virtually CCTV cameras being used today are generally for surveillance and security purposes. CCTV system is available in nearly all banks, casinos, and big malls. Most ordinary family and pop stores also have CCTV system included for security purposes. In order to install CCTV in your life, you should use a CCTV Security Tester to test the equipment and make sure that the CCTV systems can work smoothly.

What is CCTV?
CCTV also known as video surveillance, is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in which the signal is not openly transmitted, though it may employ point to point (P2P), point to multipoint, or mesh wireless links. Almost all video cameras fit this definition, the term is  often applied to those used for surveillance in areas that may need monitoring such as banks, casinos, airports, military installations, and convenience stores.

CCTV Security System
Whether at home or on business, we all feel comfortable to know that we can be safe and secure. You may not be able to be on guard 24-hours a day, but thanks to CCTV cameras and other home security camera systems, you can protect yourself without the cost of employing a security firm. Personal CCTV systems also provide a visible deterrent to intruders, while the modern technology used in many security camera systems today means you can integrate your cameras with your TV, PC, smart phone and tablet.

What is a CCTV Security Tester?
CCTV Security Tester is a kind of multi-function test tool for CCTV and security camera installation professionals. CCTV Camera Tester aims at realizing CCTV security system installation and maintenance. With its Optical Fiber Communication test, low power circuit test, video test and PTZ control, and DC12 1A output for camera test functions, it can help solve many problems of security system. It could also be used in laboratory tests, equipment maintenance, etc.

Introduction of Fiber Optic Cleaving

As we know, in most cases, when a fiber is used or spliced, it is essential to prepare clean ends. Stripping, cleaving, polishing are the basic steps to ensure fiber ends clean and smooth. Since we have discussed fiber optic splicing and polishing in the last several weeks, we must know more about them. Cleaving, an essential step of making fiber ends clean, though it’s a simple mean, but it works surprisingly well, at least for standard glass fibers. Thus, I want to share something about the cleaving in this paper today.

Understanding Of Cleaving

Cleaving is one of the processes for termination or splicing. Simple to understand, it “cut” an optical fiber or makes it precisely broken, just like cutting glass plate. But it is different from the general concept “cut”, or perhaps, we may define it as a professional “cut technique” because fiber is cut by scoring or scratching the surface and applying stress so that the glass breaks in a smooth manner along the stress lines created by the scratch. With a properly well done cleaving, the fiber will cleave with a clean surface perpendicular to the length of the fiber, with no protruding glass on either end.

Cleaving Tool

cleaverCleaver – If you have more experiences in the cleaving and splicing, you must know that a right cleaver helps cut out costly mistakes. The working principle of cleaver is very easy to understand. It first holds the fiber under low tension, scores the surface at the proper location and then applies greater tension until the fiber breaks. Automatic cleavers now are widely used because they can produce consistent results, irrespective of the operator. It is easy to use and does not need training. Users just need to clamp the fiber into the cleaver and operate its controls. In addition, there are some cleavers less automated. This kind of cleavers are more dependent on operator technique and less predictable as they require operators to exert force manually for breaking the fiber.

scribeScribe – Except the cleaver, there is another tool for cleaving which is typically used to remove excess fiber from the end of a connector before polishing. Scribe is a simple hand tool with a hard, sharp tip (generally made of carbide or diamond), that is used to scratch the fiber manually (some scribes are with pen-style shapes). Then the operator pulls the fiber to break it. However, it is less predictable than a cleaver because both the scribing and breaking process are under manual control. Nonetheless, scribe can produce adequate results for polishing so that it is still used today.


Why Is Proper Cleaving So Important?

To get good fiber optic splices or terminations, especially when using the pre-polished connectors with internal splices, it is extremely important to cleave the fiber properly. As we know, fiber splicing requires mating two fiber ends. Any defect of the ends would impact the performance of fiber splicing. For example, if the fiber ends are not precisely cleaved, the ends will not mate properly. Or if the cleaved ends are at an angle, there will be a gap between the fibers that will cause loss in a mechanical splice or uneven fusion splicing. In addition, if there is a protrusion, or lip, on one of the fibers, the two fibers will not butt up against each other and if there are hackle or mist, the ends will reflect or diffuse light, also causing loss.


Warm Tips: A good cleaver is a little expensive but it’s easy to use and do not need much techniques and can help cut out costly mistakes. Of course, inexpensive cleaver provided in most termination kits is common used. If you decide to use such inexpensive cleaver, the point you may remember is that you must learn how to use it properly. Follow directions, but also do what comes naturally to you when using the device, as they are sensitive to individual technique.
