To combat video signal attenuation, CCTV installers utilize which of the following?

In addressing video signal attenuation in CCTV systems, a balanced amplifier is often preferred because it enhances the video signal over long distances, mitigating the impact of attenuation.

Video signal attenuation occurs when the signal strength decreases due to long cable runs or interference. A balanced amplifier helps maintain the integrity of the signal by balancing the load and reducing noise that can accumulate along the cable. This is particularly important in environments where electromagnetic interference is a concern, as balanced systems are designed to reject noise and maintain signal quality.

While signal boosters can amplify a signal, they may not adequately manage noise interference introduced along a cable run. Similarly, unbalanced amplifiers typically do not provide the same level of noise rejection as balanced amplifiers. Digital converters, while useful for converting between analog and digital signals, do not directly address the attenuation issue for transmission.

Thus, a balanced amplifier is the suitable choice for combating video signal attenuation in CCTV setups.
