Data Transmission, Images & Recording

What is the maximum distance over which video signals can be reliably transmitted without significant loss of quality using RG59 coaxial cable?

• 500m

• 750m

• 1000m

• 1500m

Coaxial cables used in CCTV systems have certain limitations. What primarily causes these limitations?

• Interference from external devices

• Signal degradation over long cable runs

• High cost of cable production

• Complexity of installation

Which of the following best describes the use of coaxial cables in CCTV systems?

• Primarily for power transmission

• For transmitting digital audio signals

• For transmitting analog video signals

• For internet connectivity

Compared to coaxial cables, twisted pair cables offer:

• Lower noise immunity

• Better noise immunity

• Higher signal attenuation

• Less flexibility

What is the maximum distance for transmitting video using passive baluns with twisted pair cables?

• 1200m

• 400m

• 100m

• 800m

How does the signal quality of twisted pair cables change with increasing cable length?

• It remains stable

• It improves

• It diminishes

• It fluctuates unpredictably

Why are optical fiber cables less commonly used for analog video transmission in CCTV systems?

• They are too flexible

• They require specialized equipment and have higher installation costs

• They have low bandwidth

• They are not durable

Compared to coaxial and twisted pair cables, optical fiber cables offer superior:

• Flexibility

• Cost-effectiveness

• Bandwidth and distance capabilities

• Ease of installation

What is the maximum cable length for Ethernet connections using Category 5e or Category 6 cables to ensure optimal performance?

• 50 meters

• 100 meters

• 150 meters

• 200 meters

Which types of cables are mentioned as offering reliable data transmission over short to moderate distances in local area networks (LANs)?

• Coaxial cables

• Fiber optic cables

• Category 5e (Cat5e) or Category 6 (Cat6) cables

• HDMI cables
