Wireless Transmission of CCTV Systems in Hazardous Environment Zone 1

CCTV systems in Hazardous Environment Zone 1 may require wireless transmission due to specific needs.

These wireless transmission devices replace twisted pair cables, the medium used for video and communications transmission in networked explosion-proof CCTV systems . It should be noted that all wireless transmission devices (such as access points, bridges or antennas) must be ATEX or IECEx certified. Alternatively they must have an explosion-proof enclosure or be installed in an explosion-proof cabinet.

• Wi-Fi (Standard 802.11 Protocol)

  Typical Indoor Range

  Approximately 30-50 meters (100-165 feet) due to walls and obstructions.

  Outdoor Line-of-Sight Transmission

  Can reach up to 300 meters (1,000 feet) or more, depending on equipment and environmental conditions.

• Point-to-Point Wireless Bridges

  Typical Range

  Specialized point-to-point wireless bridges can achieve ranges of 10 kilometers (6.2 miles) or more, especially when using single-mode fiber connections for data backhaul.

  High-Frequency Solutions

  Some advanced systems can reach distances of up to 30 kilometers (18.6 miles) with appropriate equipment and line of sight.

• Licensed Microwave or RF Links

  Typical Range

  These systems can cover distances from 1 kilometer up to 10-20 kilometers (6.2 miles) or more, depending on the equipment and frequency band.

  Line-of-Sight Requirement

  These systems generally require a clear line of sight between the transmitter and receiver to avoid signal degradation.
