WHAT IS WIRELESS VIDEO?
A standard wireless video system consists of a transmitter, a receiver, antennas and power supplies. A standard wireless video system transmits an analog video (NTSC or PAL) and audio signal. Transmission distances vary depending on antenna selection. These systems are "simplex," meaning they transmit the signal from the transmitter to the receiver in one direction only. ( 900 MHz, 2.4 Ghz and 5.8 Ghz ranges )

A wireless data transmission system consists of two transceivers, antennas and power supplies. A standard system transmits a digital signal using spread spectrum technology. Again, the distance depends on antenna selection. These systems are "half-duplex," meaning that signals transmit both directions, but only one direction at a time. Data can be transmitted from point to point or from a single point to multiple points. These systems are commonly used as a control link for Pan/Tilt/Zoom systems or any other application requiring the secure, efficient transmission of data.

WHY CONSIDER WIRELESS?
Wireless transmission systems, video/audio or data, are an intelligent alternative to "hard wired" solutions for a variety of reasons:

Improved technology - Advances in wireless technology allow for reduced signal interference and overall system reliability.

No license requirements - It's FREE - all "FCC part 15" products have the correct FCC approvals and do not require user licensing.

Immediate installation, no permits required - Have you ever tried to get a permit from a local, state or federal agency for trenching across a highway, street, river or railroad tracks? Permits are not necessary.

No trenching - Don't bust the budget! The cost of trenching increases rapidly as the distance required to send the signal increases. With a wireless system, simply change the antenna selection and send it through the air. Accomplish projects previously considered cost prohibitive.

Mobile & Temporary - Our small and durable systems are ideal for construction sites, covert operations and all types of public events. For maximum flexibility and portability, utilize a solar panel or battery for your power requirements.

Convenience & Performance - Have an immediate need? Install it and use it for a day, a week, a year or indefinitely - when getting real-time high-resolution video, audio or data from point A to Point B, wireless technology is the convenient, effective and efficient solution.

Cost Effective - Eliminate the high cost of installation and maintenance of fiber, cable, or twisted pair. Also eliminate the re-occurring cost of DSL, ISDN, T-1 and other types of communication links.

THREE IMPORTANT CONCEPTS

LINE OF SIGHT

A clear and wide-open line of sight is needed between the transmit and receive antennas. Wireless video cannot transmit through concrete, earth, steel, water, or trees. Anytime the transmission median is interrupted, there is a risk of signal loss. If a wireless signal could be viewed from the side, it would be shaped like a football, expanding in an elliptical fashion. In order to achieve a cable-quality signal, the application must be clear of obstacles that would obstruct any part of the signal path. Systems can be relayed, or antennas can be remoted to avoid obstructions.

INTERFERENCE

Any wireless signal within the same area that is transmitting at or around the same frequency as your system may cause interference. Every potential application site should be surveyed with a spectrum analyzer, frequency locator or demonstration system prior to installation. Interference is common at the 900 MHz levels and 2.4 Ghz levels. Common causes of interference are microwaves, cordless phones, wireless LAN/WAN's and other wireless systems. We recommend using the 5.8 Ghz frequency band for video transmission to minimize the chance of interference.

THE FCC

The Federal Communications Commission (FCC) is an independent United States government agency, directly responsible to Congress. The FCC was established by the Communications Act of 1934 and is charged with regulating interstate and international communications by radio, television, wire, satellite and cable. The FCC's jurisdiction covers the 50 states, the District of Columbia, and U.S. possessions. If a wireless system in use does not comply with FCC standards, fines may result for the end user should the FCC prosecute.

AACOM tests all cameras and devices before installation for business camera systems including : Panasonic - Sony - JVC - Samsung- Sanyo - Pelco - Dedicated Micros - Tempest - PcOpen - etc
