Technology That Provides Security From A Distance

Proper security is essential for enhancing safety and protecting important data in a wide variety of industries. However, obstacles such as distance restrictions can limit the ability to connect security equipment, hindering effective security measures. Fortunately, many different types of industrial networking equipment can effectively network devices from control rooms to security access locations. To learn about key technology that provides security from a distance, continue reading..

Security cameras are a common type of security equipment used to record activities. They can detect and prevent crime to enhance the security of an area. When it comes to improving security from a distance, 4K security cameras are unsurpassed. Offering the highest level of detail and clarity available, 4k security cameras are equipped with specialized long-distance lenses for long-range surveillance. They include larger image sensors than standard HD security cameras, so they can capture more light, which results in improved color, low-light performance, and contrast.

Equipped with innovative H.265 video compression, 4K IP camera systems also have the capability to keep file sizes low without sacrificing video quality. Furthermore, 4K cameras provide advanced zooming capabilities, which allow them to zoom in on a distant object while maintaining good image quality. As such, 4K cameras are invaluable pieces of equipment for improving security from a distance.

PoE Ethernet extenders provide Power over Ethernet (PoE) to standard-based PoE- and PoE+-compliant devices, such as IP cameras and wireless industrial access points, over extended distances. Using PoE technology, these extenders allow IP video and network installers to extend Ethernet far beyond the general IEEE 802.3af limits of 328 feet (100 meters) that Cat5e and Cat6 Ethernet connections typically provide. Thus, PoE Ethernet extenders can greatly enhance the distance at which security can be provided.

Antaira Technologies offers a wide range of networking equipment that can enhance your long-distance security capabilities—from PoE ethernet extenders to our industrial wireless (IEEE 802.11) series, which provides a long-range, point-to-point, pre-configured wireless bridge for enhanced remote security.

2.4GHz, 5GHz, and 6GHz are wireless frequencies based on electromagnetic spectrum wavelengths. Each wavelength has its own characteristics for each frequency. The 2.4GHz wavelength is long and dense, making it a great choice for long distances or in areas with lots of obstructions and great for penetrating floors, drywall, concrete or steal. 5GHz has a shorter wavelength making it ideal for high-speed applications in open areas where obstructions are limited. 6GHz, is set to be the fastest of the three frequencies but we will have to wait and see.

The 2.4GHz wireless spectrum consists of 14 channels, however, not all channels are available for use. Different countries have different regulation bodies that control which channels can be used. In North America, the FCC regulation permits the use of only channels 1 - 11, while channels 12 - 14 are not permitted.

The 11 available channels are 20MHz wide with a 5MHz of spacing between them. The 5MHz spacing causes channel overlapping which leads to poor connectivity and undesirable results. For these reasons, in North America, it is considered a best practice method to use only use channels 1,6,and 11 - the three non-overlapping channels. You can arrogate 2 x 20Mhz channels into 1 x 40Mhz channel for increased throughput, but this option restricts channel availability and is not recommended.

2.4Ghz supports IEEE 802.11b /g /n networking protocols. Each of these protocols use 20MHz channels, with the exception of 802.11n which can be used for both 20 and 40MHz channels.

The 5GHz spectrum uses 24 non-overlapping channels divided in four different sections UNII-1, UNII-2, UNII-2 extended, UNII-3, and ISM. Each section has its own recommended uses and restrictions. Each channel is also 20Mhz wide with 20MHz of space separating the channels.

5GHz uses a variety of channel widths allowing 20MHz, 40MHz, 80MHz, and 160MHz, unlike 2.4GHz which allows for only two channels widths (20Mhz & 40Mhz). The 5GHz also supports the IEEE 802.11a /n /ac networking protocols. The higher frequency combined with ultrawide channel width plus the latest 802.11ac standard makes 5GHz ideal for high-speed wireless networking.

However, there is a downside to the 5GHz spectrum. The higher frequency also means it is less susceptible to obstacles and has a shorter distance span between the transmitter and receiver.

Applications that require higher bandwidth speeds should take advantage of the 5GHz wireless spectrum. 2.4GHz falls short of the speeds that 5GHz offers. However, if you require connectivity between two points at longer distances and speed is not an issue, or if you have legacy equipment that requires wireless connectivity or have large obstacles in between your transmitter and receiver then 2.4GHz would be your best choice.
