A Rockin’ Radio Range
The AW900 system from AvaLAN is a wireless point-to-point Ethernet bridge system operating in the 900 MHz frequency range and delivering over 1.5Mbps raw data rate. The AW900 radios have no IP addresses and no browser interface. Instead, upon startup the radio simply finds its matching radio (keyed by serial number), selects the quietest of 12 available channels, and begins transmitting 128-bit encrypted Ethernet packets at 1.5 Mbps. AvaLAN says that initial reports from early-adopter field tests are showing a dramatic increase in performance vs. 2.4 and 5.8 GHz 802.11 systems in terms of range and successful bandwidth transmission for NLOS applications.

CCTV Cable Line Expands
Belden introduces an innovative new cable design for pan/tilt/zoom (PTZ) cameras used in closed circuit television (CCTV) surveillance systems. Belden New Generation Banana Peel PTZ Composite cables are suited to security applications in hospitals, airports, amusement parks, retail establishments, universities, casinos, sports stadiums and correctional facilities—wherever there is a need for a protective CCTV surveillance installation to monitor people, activities and/or assets. New Generation Banana Peel PTZ Composite cables are offered in both riser and plenum versions. And, in order to accommodate control encoding schemes or protocols such as Manchester, Sensornet and RS-422, they are comprised of the following components: one RG-59 coaxial cable (for video); 1-Pair 18 AWG cable (for power); one 23 AWG UTP or one 22 or 18 AWG STP (for control).

Warding Off Disaster
Dantel, Inc. presents the Disaster Resistant Event Network, a cellular-based TCP/IP solution using solar power that offers sturdy, comprehensive event monitoring and reporting capabilities for use in remote locations. The Disaster Resistant Event Network allows users to implement remote event monitoring in areas where traditional physical networks can’t reach.
In addition to its solar power option spanning a few watts to several hundred watts, the robust communication system offers various configuration options ranging from cell-based wireless Wide Area Network (IP Protocol) rates to a few hundred thousand bits per second with a higher bandwidth rate of several million bits per second. In addition to the cell-based communication WAN link, the integrated point-to point wireless IP network connects adjacent units placed several miles apart with a communication link of up to several million bits per second, ideal for event-based two-way video-enhanced alarm messaging and controls.

Keeping an Eye on ATMs
The DV-IP ATM from Dedicated Micros captures and records ATM transaction data with the corresponding video input. The four-camera unit records at 60 PPS and is available with 80GB, 160GB, 320GB and 600GB, providing up to two weeks, one month, two months and four months of online video storage capacity at SVHS quality (at a standard record rate of 3 PPS and 18 Kb file size).
A spot monitor output provides a visual deterrent as it indicates that lobby cameras are being recorded. The output can be configured to display both a full screen and a full screen sequence with programmable dwell time. The ATM Interface integrates Automatic Teller Machines and the DV-IP range of video servers including the DV-IP ATM. The module receives, decodes and stores data from the ATM alongside the relevant video images on the Server. One ATM Interface Module can simultaneously support up to three ATMs. Measuring only 3.3” (H) x 8.85” (W) x 12.67” (L), the DV-IP ATM can be installed almost anywhere—even inside the ATM machine. Multipurpose mounting brackets permit horizontal or vertical mounting. For more information, visit www.dedicatedmicrosus.com.
Alarm Communication over the Net DSC’s DVACS Internet alarm communicator, the T-Link TL250D, communicates alarm system information over the Internet instead of the dedicated DVACS communication circuit. DVACS is commonly used in Canadian commercial applications to communicate with a central monitoring station receiver. Integrators can go to any existing Sur-Gard DVACS control panel or existing DSC DVACS module and replace DVACS communication with existing broadband communication. Adding the TL250D without having to upgrade the control equipment means minimal up-front cost. For more information, visit www.dsc.com.
