Industrial Networking for Security Equipment
Fire Alarm Monitoring
Safety is a valuable asset. In a fire alarm system, a variety of devices work together with fire alarm panels through visual and audible alerts when smoke, fire, carbon monoxide, or other emergencies are present. These fire alarm codes are then immediately reported to a local fire prevention control center. In most metropolitan areas, buildings are required to install multiple fire alarm panels on each floor in order to pass along fire alarm codes to trigger warning signals and expedite the evacuation process.
The principle of networking involves connecting several panels together to form a system that allows different panels to be monitored by one geographical monitoring system. Typical fire alarm panels are designed with proprietary serial protocols that transmit fire alarm code information. Due to distance and environmental concerns, a serial fiber network can be implemented to overcome the typical serial copper cable length limitation of 1.2Km.
A dual serial to fiber network is also an effective way to decouple systems and reduce the risk of a portion of a facility going offline at any time due to system failure or maintenance requirements. Antaira’s industrial serial to fiber media converters are designed to ensure 24/7 and long-lasting operation. Each unit inside the fire alarm panel supports dual fiber connections to prevent data loss to the fire prevention control center.
Solutions and Benefits
- Antaira’s industrial serial to fiber Series provides a redundant serial fiber network to prevent data loss and reliably transmit fire alarm code to a remote fire prevention control center
Most secured facilities provide limited access to the general public. Traditionally these facilities relied heavily upon security guards to monitor traffic to and from the facility. Today, additional access control and security surveillance equipment is being implemented in order to improve efficiency and provide remote monitoring support to security guards.
In order to improve surveillance at the security gate, security equipment, such as PoE cameras, road blockers and badge readers might need to be added and connected to the network. Serial, fiber-optics, Ethernet and wireless are all different types of communication mediums that can be used to transport data from end security equipment to the network.
Obstacles such as distance, weather, and construction restrictions can provide limitations to how equipment can be connected. Laying hardwire cable or fiber optics from the security access gate to the main building can require expensive trenching and be time consuming. Therefore, wireless communication equipment would be the most efficient way to network devices from the main building’s control room to the security gate access location.

- Antaira’s industrial managed ethernet switch series provides layer 2 network management software allowing users to remotely monitor and manage the network. Managed switches also allow notifications of various events and warnings.
- Antaira’s industrial wireless (IEEE 802.11) series provides a long range point-to-point pre-configured wireless bridge. Information such as username, password and SSID are provided to greatly reduce installation times.
Equipping fleets with mobile video surveillance systems has become an essential part of the transportation industry. The presence of cameras onboard buses can not only deter fights, vandalism, robberies and assaults, but can also be used in investigations regarding traffic accidents. The reliability of the networking equipment is pertinent in order to transmit on-board security footage to a central location, therefore industrial grade products that are certified to operate under the constant shock and vibration environment of an on-vehicle application are required.
When an event occurs, control room operators at the bus depot will then be notified of the recorded event and will process requests for wireless transfer of video and other data when the bus arrives back at the depot. The data that is stored on the bus is automatically transferred wirelessly to the control room when the bus arrives back at the depot. For this wireless application, a wireless client is installed aboard each bus. While the buses come into the depot, each bus can connect with the IP67 rated access point and wirelessly download on-board security footage quickly and reliably.
In addition, power available on-vehicle is typically limited to 12VDC which can provide additional power challenges for PoE cameras, typically requiring 48VDC. Using voltage booster technology, an industrial grade PoE switch, designated with a -24, can use a low voltage input of 12~36VDC, and increase the power output to 48~55VDC required for PoE applications.

Parking Lot Surveillance
Video surveillance technology plays an important role in improving security at many facilities worldwide. Statistics have shown that 80% of criminal acts reported to police at public centers and business offices occur in parking lots. To deter vandalism, theft, and other crimes, facilities are deploying video surveillance as part of a full range of security measures to remotely monitor/access/control site equipment from a central location.
Compared with an indoor setting, parking lots impose several additional requirements on surveillance networks, particularly because these environments are often in remote locations and subjected to a wide range of temperatures due to the outdoor location. Industrial Ethernet switches that support wide operating temperatures and PoE capabilities can fulfill these types of requirements. Managed Ethernet switches will ensure the ability to remotely monitor access/control any equipment deployed in the parking lot from a central location.
Trenching or cabling wire from each camera in the parking lot back to the main building can be very expensive. Therefore, instead of physically trenching cable, wireless communication is the most cost-efficient solution for sending video back to a central location.
Solutions and Benefits
- Antaira’s industrial managed ethernet switch series provides layer 2 network management software allowing users to remotely monitor and manage the network. Managed switches provide standard features such as QoS, SNMP, IGMP, and IEEE 802.1Q. Additional PoE features, such as, remote PoE power management and automatic end device power recovery can also be managed.
- Antaira’s industrial wireless (IEEE 802.11) series provides an IP67 waterproof rating and extended operating temperature design to support harsh outdoor wireless network applications. The unit’s omnidirectional antennas support connections from multiple directions simultaneously and are ideal in applications where the end device might provide movement.
