In the era of universal digitalization, video surveillance has become an integral part of ensuring the security of both private property and public spaces. The choice of cameras, recorders and monitors is only the tip of the iceberg of an effective system. A key role is played by a seemingly inconspicuous element - cable products, which can be purchased on the website https://rusmarta.ru/market/kabelnaya-produktsiya/It is the cables that become the circulatory system that ensures stable data transmission and uninterrupted operation of the entire video surveillance system.

Don't underestimate the importance of choosing the right cable.

A poor quality or unsuitable cable can lead to a number of problems:

• Signal loss and interference. Low-quality materials and poor shielding lead to deterioration of image quality, noise and even complete loss of signal. This is especially true for analog systems, where image quality directly depends on the quality of the transmitted signal.
• Limited transmission distances. Different types of cables have limitations on the transmission distance of the signal. Exceeding these limits leads to weakening of the signal and distortion of the image.
• Reduced system reliability. Low-quality cables are subject to rapid wear, breakage and damage from external factors (temperature, humidity, mechanical impacts). This leads to unstable system operation and frequent breakdowns.
• Increased maintenance and repair costs. The need to frequently replace cables and troubleshoot problems caused by their failure significantly increases operating costs.

What cables are used in video surveillance?

Experts of the company RusMarta note that the choice of cable depends on the type of video surveillance system and the required parameters:

• Coaxial cable. The traditional option for analog systems. Provides video signal and power transmission via one cable (optional). There are many varieties, differing in characteristics and price. It is recommended to use high-quality coaxial cable with a high degree of shielding (RG-59, RG-6).
• Twisted pair (UTP/FTP). Used in IP video surveillance to transmit data over an Ethernet network. The special feature is twisting the conductors in pairs, which reduces electromagnetic interference. Twisted pair categories (Cat5e, Cat6) determine the data transfer rate. For video surveillance, it is recommended to use Cat5e or Cat6. FTP cable (with shielding) is more resistant to interference.
• Fiber optic cable. Used to transmit data over long distances without loss of quality. Has high bandwidth and resistance to electromagnetic interference. Used in complex video surveillance systems that require the transmission of large amounts of data over significant distances.
• Combined cable. Combines coaxial cable and power wires. Convenient to use, as it allows you to connect the camera with just one cable.

Key features of the cable:

• Conductor material. Copper is the best option, providing good conductivity and low resistance. Copper-clad aluminum (CCA) is a cheaper alternative, but is inferior to copper in terms of characteristics.
• Conductor cross-section. Affects the signal transmission range and permissible current. A thicker conductor allows the signal to be transmitted over a longer distance and can withstand a greater power load.
• Insulation material. Determines the cable's resistance to external influences (temperature, humidity, ultraviolet radiation). It is important to select a cable with insulation that meets the operating conditions.
• Shielding. Protects the signal from electromagnetic interference. Shielding can be made in the form of foil or braiding. The denser the shielding, the better the protection from interference.
• Wave impedance. An important parameter for coaxial cable. It must match the wave impedance of the equipment (usually 75 Ohm).

Recommendations for selection and installation of cable products:

• Consider the type of video surveillance system. For analog systems - coaxial cable, for IP systems - twisted pair.
• Determine the transmission range requirements. Select cable based on the required signal transmission range. Use signal amplifiers if necessary.
• Provide protection from external factors. Use a cable with appropriate insulation and protection from ultraviolet radiation, moisture and mechanical damage.
• Choose trusted manufacturers. Give preference to cable products of well-known brands that guarantee quality and compliance with the declared characteristics.
• Perform installation correctly. Avoid bending or damaging the cable during installation. Use special tools for crimping and connection.
• Test the system after installation. Check the signal quality and functionality of all cameras after installing the cable system.

The correct choice and competent installation of cable products is the key to a reliable and effective video surveillance system. Do not skimp on the cable, because the image quality, stability of operation and durability of the entire system directly depend on its quality.
