The Evolution of Wireless Technologies

Advancements in RF allow integrators to tap into new installation opportunities

Remove the constraints of traditional hardwired IP video surveillance—such as cabling, infrastructure and power—and a brave new world of deployment possibilities open to systems integrators and their customers.

For those customers hand-tied to the restraints of IP video surveillance, a true wireless solution delivers a host of new options. No power source nearby? Impossible to reach a hardwired infrastructure for your LAN deployment? A remote location that mandates perimeter security but never had the reliability with former equipment? Now there is a solution for each of these challenges. With new and improved wireless surveillance camera capabilities, more installation options abound, including public events, venues or government gatherings, construction sites, agricultural areas, law enforcement and public safety, recreational facilities, transportation, utilities, commercial sites and parking facilities.

Traditional, first-generation wireless cameras required cabling for power, and routing the power source remains a major impediment to the broad adoption of wireless cameras in a variety of applications. While wireless cameras sometimes deliver adequate video quality, systems integrators never had the confidence that these wireless solutions would have the quality and reliability to rely on these solutions. Common problems included dropped connections, interference issues with other wireless devices causing image quality and the collapse of surrounding Wi-Fi networks. These issues created a direct impact on the perception and adoption of wireless technologies. But the issues above are no longer a reality. Today’s next generation wireless providers have made significant strides in the development of more robust solutions.


Solid returns on investment

Labor remains one of the highest costs of the installation of any traditional security project, including video surveillance. Some say labor can be as much as 60 percent of a job’s costs, even more depending on man-hours required to dig or trench, and pull wire and cable. Trenching costs range from $50 to $1,000 per foot. For example, 100 yards of trenching can cost anywhere between $22,000 and $45,000 with an average time span of two to four weeks of completion time. Often times heavy equipment must be purchased or leased, driving costs up further.

Yet surveillance is such a critical part of effective perimeter detection and security and is at the very heart of any security plan’s overall effectiveness. Therefore, the protection of outdoor areas cannot be ignored.

It’s easy to see why wireless is winning the favor of many installers and end users who dread digging or trenching. For the installer, the return on investment of deploying wireless surveillance solutions presents itself in numerous ways. At its core, wireless technology solves the problem of requiring a cable for data transmission but placing a camera where there is no available power source made it impossible to implement. In other cases, a power source was available but the wireless solution had limited range, requiring the installer to consider trenching for a power over Ethernet (PoE) solution, adding to a project’s cost and complexity.

New wireless surveillance technologies do not have these limitations. Today’s advanced solutions are fully self-contained wireless video cameras that allow for placement anywhere because there are no wires needed for power or data transmission. These systems also incorporate removable antennas, using shorter antennas to provide more margin for easier alignment and installation or substitute higher gain antennas for longer-range operation.


Opportunities abound

With this solution in hand, integrators and installers can return to existing qualified customers with new solutions to outdoor surveillance challenges as well as reach users with opportunities for surveillance in untapped applications and vertical markets. Wireless has changed in other ways as well. It’s more robust and batteries have longer life.
