QViD Technologies Wireless Security Systems
Our CCTV Team has designed and implement many wireless video surveillance system with 100% successful rate. We are experts on wireless security system, and the reason is simple: Our CCTV Team is formed by engineers, not technicians.
There is many companies offering security systems for commercial and residential customers, but when it comes to design a wireless video surveillance system, you need people with the knowledge and experience in wireless networking.
QViD Technologies has implemented wireless video surveillance in condominiums, warehouses, marines and ports with excellent results.
Our equipment is proven to work in extreme conditions and the secret on this comes from the design itself. We will make a survey of the site, to verify the complexity of the project and we will select the wireless access points and antennas required to make it work.
Wireless Video Surveillance is an option that must be considered in cases where cabling is an utopia, due to distances and conditions of the site.
How Wireless Video Surveillance works?
The design of the wireless network is the key to the success of the application. Security Cameras video feed can be sent from remote locations using wireless access points in conjunction with video encoders. These video encoders usually come for 1 camera or 4 cameras, depending the location.
The whole point is to form video nodes for up to 4 cameras to get the video signal from each one of them to the video encoder. This useful piece of hardware transform the video signal from all the cameras into just one feed to be transmitted as a data signal using TCP protocol, just like computers communicate. This data feed goes to the wireless access point, that transmit the data signal wireless using 802.11a/b/g protocol through a 5 GHz antenna. The data signal is received by a Receiving Station located where the NVR system will be located (usually guard security house, central office, etc) and decoded by the NVR system for recording.
The great thing about these wireless systems is that there are no limitations in the number of video feed received by the system, making these systems a great option whenever more than 16 cameras are needed on the site.
Every transmitter will be "hooked" to the receiver, using encryption WPA security and MAC filters, to avoid any intrusion on the bandwith by any other wireless device present on the location.
Depending on the application, external antennas could be needed in order to increase the power of the signal, nut in most of the cases, the internal antenna of the access points will be enough.
