A Crash Course in Bluetooth Technology

In today’s world, electronics need to connect to one another everywhere you go – at home, at the office, in your car, the coffee shop, everywhere! The easiest, most secure and fastest connection available today is Bluetooth. You hear that word all the time, but what exactly is “Bluetooth?”

Bluetooth is an open/unlicensed wireless protocol that is used to exchange data over short distances from a wide variety of devices. Bluetooth was designed as an alternative to the RS232 wired data cable systems and it can connect several devices together without any problems with synchronization. Bluetooth capable devices can have a range from 30 feet to well over 100 feet depending on the device and version of Bluetooth.

Bluetooth devices use short radio waves to transmit the data using a technology called frequency-hopping spread spectrum which divides the data being sent and transmits each piece individually over (up to) 79 different frequencies. Bluetooth is such a versatile protocol and utilizing the technology you can connect and exchange information between cell phones, regular telephones, laptops, desktop computers, GPS systems, digital cameras, video game consoles, and more. Bluetooth makes it possible for all of these devices to communicate with one another when they are in range of one another – and best of all, since the devices use radio waves for communication, they do not require line-of-site to work properly.



Bluetooth has evolved out of several wireless technologies to become the new industry standard protocol. It is designed for low power consumption within a short range, but right now the prices vary widely for the technology depending on the application. Bluetooth devices also have the ability to maintain high levels of security even though the data is being transmitted wirelessly. The developers of the technology have put an emphasis on secure connections since the very beginning. Be aware though, that the manufacturer of the specific device that houses Bluetooth capabilities determines what level of security their specific device has.

Not surprisingly, Bluetooth has also moved into the security and surveillance arena where it is opening many new doors for camera systems and sensors.

LED Technology… Then, Now and Tomorrow.

LEDs or Light Emitting Diodes were first designed and built in the 1920s but were impractical for commercial use until 1962. Basically, when the diode inside of an LED is switched on the electrons are able to recombine and release energy in the form of a very bright light; this is called electroluminescence. The color of the light emitted is determined by the energy gap of the semiconductor in the LED. Early LEDs were only available in the color red but modern ones are available in any color across the visible spectrum, plus the ultraviolet and infrared wavelengths.

LEDs present many advantages over other light sources because they consume much less energy, they produce more light per watt than traditional lighting like incandescent bulbs, they have a much longer lifespan, they light up very quickly, they are brighter in intensity, they need no filters to emit specific colors as traditional bulb lighting does, they are not nearly as fragile as bulb lights are, and they are very small in size. LEDs also have very long life spans if they are kept in operation at low currents and low temperatures; most will last anywhere from 25,000 to 100,000 hours each.

LEDs have very few disadvantages but they do initially cost a bit more than conventional lights, they require a lower temperature environment to operate properly, and they are more sensitive to current/voltage fluctuations which therefore will need to be a bit more precise when utilizing LEDs.



LEDs can be used in many applications in many different industries, they are also a very environmentally friendly option because of their small size, low power usage and because they are completely non-toxic. They can replace traditional lighting like fluorescent bulbs; they are more practical for appliances such as televisions, radios, calculators and watches. Companies now make super-bright flashlights with LEDs. Since the LED is completely sealed they are perfect for outdoor signage since the elements will not affect their operation so they are now used for highway signs, construction, advertisements and they are even now being used to replace and upgrade traffic lights for better visibility.

Recently there have been some amazing advancements in LED technology… there has been talk that LEDs will be used for new strip-style lights to replace fluorescent bulbs in office environments that will also have the capability to interact directly with your computer providing your connection to the internet. No wires, no fuss.

WTI utilizes high-technology enhanced power LEDs in all of our infrared camera systems, like the Ambervision series for example.

WTI’s Sidewinder Displayed at FRI!

The Annual Fire and Rescue International Show was held in Dallas, Texas in August of this year. It featured the latest in fire and rescue equipment and technology and is attended by fire department officials from all over the world.

This year, Frontline Communications and Pierce Manufacturing showcased a Command Post Vehicle that they custom-built for the Frisco Texas Fire Department. It features the latest in satellite, video and communication technologies. It houses 10 different monitors, radio and telephone communications and 6 work stations, each with a laptop computer. It also has a large conference room in the back of the vehicle where fire and other emergency officials can strategize for large incidents and events.



WTI’s (Wireless Technology, Inc.) High Definition and Standard Definition Sidewinder Cameras were featured on the two masts on the command vehicle. The Standard Definition Sidewinder P/T/Z camera provides 360° continuous rotation on both pan and tilt axes with 35X optical zoom and 12X digital zoom for high quality, long range viewing of large events, hot spots and other fire or medical incidents.





The High Definition Sidewinder camera features 360° continuous pan rotation and + or - 90° tilt rotation, 1080I/720P HD, 16:9 widescreen format, 10X optical zoom with a 10X digital zoom. The Sidewinder cameras offer the ability of close-up facial and body recognition shots. Both SD and HD Sidewinder are color day and black and white nighttime vision cameras.

Another Sidewinder (standard definition) camera was displayed on the mast of the Frontline Communications’ demonstration command vehicle.





This vehicle has 4 monitors inside with a flat screen TV / monitor on the outside. This vehicle is a smaller version of the command post vehicles Frontline builds for its clients but it does still house the latest in video, satellite and communication technologies.

WTI’s Sidewinder cameras were just some of the highlights of Frontline Communications and Pierce Manufacturing vehicles at this year’s FRI Show. WTI is working very closely with Frontline Communications and Pierce Manufacturing to improve the technologies throughout the entire fire and command post vehicle industry.

Together WTI and Pierce have developed a wireless camera system specifically for Aerial Fire Trucks. The video is transmitted wirelessly from a Sidewinder camera back down to the truck for better view of the surrounding fire hot spots, to assist in looking for survivors or any other emergency incidents in the area where the aerial truck has been deployed. The video can also be viewed on a laptop with wireless connectivity via an IP address. This means that the Chief or the command post can both view the video from the aerial truck from remote locations.

Frontline Communications and Pierce Manufacturing have also installed Sidewinder cameras on military vehicles and television ENG vans for the broadcast industry.
