Next-generation wireless cameras are built from the ground up for surveillance with a proprietary wireless protocol developed to overcome the unique challenges of transferring high bandwidth video over the air efficiently. These devices leverage the intelligence of a new type of wireless protocol to allow control data from a central networking hub to be communicated over 915 MHz, while the 2.4 GHz band transfers the stream of video data. Unlike other wireless surveillance cameras that transfer data when it is ready, new systems leverage intelligent software to transfer data only when it detects an empty ‘airspace,’ meaning minimal interference with other devices. This decreases the opportunity for packet collisions and interference. Also, these advanced algorithms are more efficient than standard Wi-Fi retransmit, requiring less airtime when transmitting compressed video. Using a proprietary video protocol results in an inherent security feature, as standard WiFi intrusion devices are not compatible.
Developed specifically for use in wireless surveillance deployments, this advancement helps users get the most reliability and security.
Robust wireless surveillance systems also detect when a camera or video connection is lost and take immediate action to counteract and recover the connection. With automatic recovery, the VMS system eliminates numerous fals alarms that are generated from the numerous “video loss” detections that had resulted from the use of first generation wireless cameras.
In the field, solar cells power the camera for outdoor applications and provide round-the-clock video surveillance system operation with an integrated battery that allows continuous 365/24/7 operation, since the batteries can last over five days without additional recharge. This provides end users with a solution that can truly protect a wide-ranging perimeter environment in a cost-effective and reliable manner. The misconceptions of wireless technology are no longer applicable and security teams can now realize the true benefit of wireless surveillance, beginning with effective perimeter security.
Removing the constraints of video surveillance—such as cabling and infrastructure— opens up a world of possibilities for systems integrators. Now they can complete jobs faster and add more projects to the queue. Integrators can also go back to current clients to offer wireless where perhaps they couldn’t before, or where a new need has arisen. They can offset the high costs of cabling with more and quicker deployment of installations—and continue to show their expertise in the surveillance field.
