The coaxial power connector is the most common in the practice of video transmission and the cheapest, most reliable, most convenient and easiest way to transmit electronic images in television surveillance systems.

What Is It?

Coaxial cable is manufactured by many manufacturers with a wide variety of sizes, shapes, colors, characteristics and parameters. Most often it is recommended to use cables of the RG59 / U type, but in fact this family includes cables with the most diverse electrical characteristics. In television surveillance systems and in other areas where cameras and video devices are used, the RG6 / U and RG11 / U cables similar to RG59 / U are also widely used.

Although all these groups of cables are very similar to each other, each cable has its own physical and electrical characteristics that need to be taken into account.

The Groups for You

All three mentioned groups of cables belong to the same common family of coaxial cables. The letters RG mean “radio guide”, and the numbers denote different types of cable. Although each cable has its own number, its characteristics and dimensions, in principle, all these cables are arranged and work the same way.

The Frequency

The frequency dependence of the attenuation characteristic on the length limits the distance of application by the requirements for the resolution in the system. For systems with a high resolution (more than 400 TV lines), the following restrictions must be observed: for cables RG-59 or RC-75-4, the maximum video transmission distance is up to 300 m; For RG-11 or RK-75-7 cables, the maximum video transmission distance is up to 500 m. With a large spatial separation of the source and receiver of signals, special measures are required for galvanic isolation.

The Increase

As the length of the coaxial cable increases, the degree of interference with external noise increases, and signal attenuation increases as it passes through the cable. If a certain length of the cable is exceeded, the loss in it leads first to a decrease in the brightness, and then to the blur of the pixels and the appearance of a characteristic dark loop from the dark elements of the image.

The amount of attenuation depends on the quality of the materials used to make the cable. The linear attenuation in a coaxial cable of the RC type can be judged by its design: the larger the diameter of the internal insulation of the cables (in the cable mark designation it is indicated in millimeters after the number 75), the smaller its linear attenuation.

If the video surveillance system of best cctv Singapore supports audio, security personnel will be able to hear and access a potential attacker. From a video surveillance point of view, this function can be used as an independent identification method: when the volume reaches a certain threshold, an automatic recording will start or an alarm will trigger.

Do you plan to expand your system in the future?

It is very important that the video surveillance system is flexible and scalable. Traditional video surveillance systems are difficult to change, because they are all connected through cables. It is better to stop the selection on IP cameras that connect to the system over a wireless network, allowing you to change the configuration of the system as needed. It is very easy to connect an IP camera to a network, besides, you do not need to replace or update the cables.

What else can the video surveillance system be useful for your object?

Video surveillance can be used not only as a deterrent, but also for obtaining important evidence that can be useful during investigations and litigation.In addition, in addition to providing security, the video surveillance system can be used to collect important analytical data. For example, in the retail industry, data from CCTV cameras can improve the efficiency of IT departments, marketing, and customer service, which has a beneficial effect on customer satisfaction and business profitability.

Reverberation in House: Tips to Improve Acoustics

Drinking a drink with the neighborhood or celebrating a birthday with the whole family. A house full of visitors is always very cozy, but can also bring the necessary annoyances especially if you misunderstand each other by reverberation. The reliable Singapore home improvement professionals put a number of useful tips for you in order to realize a comfortable home!

A sleek and minimalist interior with high ceilings, plastered walls, tiles and large windows is very nice, but disastrous for the acoustics. Sound bounces off the bare, hard surfaces of your living space, causing reverberation in the home. How do you reduce this reverb without compromising the interior?

Hang curtains to reduce reverberation

For example, you can hang curtains to reduce reflections from the sound. Curtains absorb sound vibrations, provided you choose a full fabric. You achieve the best result by combining curtains with extra window coverings, such as lace curtains, roller blinds or pleated blinds.

A well furnished interior

A well-furnished interior works wonders! As you may know, fabric furniture absorbs a lot of noise. But also large plants, paintings or a bookcase make the difference. You reduce the reflection and thus reduce the reverberation.Do you have a leather sofa and are you not planning to replace it with a fabric variant? For example, place fabric chairs next to it and decorate your sofa with a number of cushions.

It is common for some scenarios that may occur in day to day life, and the most common problems that an individual or organizations face are piping and electrical problems.

So it is such important to maintain the proper connections in any construction. You might think in positive manner that all the newly constructed buildings will never have electrical connection problems whereas the old ones might have, but it is not true, everything depends on the team who performed the electrical works for that building.
