Cine Gear 2018: Teradek’s Latest Products & Radio Frequency Safety

Teradek has become an integral part of our workflow, with their Vidiu Pro device allowing us to bring live coverage of both NAB and Cine Gear 2018 shows. So we spoke to Teradek’s Mark Pederson about their latest products, as well as the recent safety concerns raised by the ICG about radiation emissions of radio frequencies from wireless devices.

Bolt XT – $1,490 to $3,990

The XT transmits and receives  1080p60 video, allowing you to monitor your feeds. Includes a built-in spectrum analyzer, manual channel selection and 3D LUTs. Each transmitter includes HDMI, 3G-SDI and looping 3G-SDI inputs, while receivers support 1x HDMI and 2x 3G-SDI outputs. Units now include several new ¼”-20 and ⅜”-16 mounting points, receivers have built-in NATO rails, and transmitters have integrated ARRI rosettes. XT units are compatible with 3rd-generation Bolt 500, 1000 & 3000 devices and Bolt LT units, making them easy to integrate into existing Bolt setups and workflows.

Bolt LT – $1,190 to $3,190

The Bolt LT is the brand new line of professional and incredibly affordable zero-delay transmitters. Available in 500 and 1000 ft. models.

The LT is the smallest and lightest model Terdek make. Each transmitter includes a single 3G-SDI or HDMI input with matching looping output, while the receiver includes a single 3G-SDI or HDMI output. Several ⅜”-16 and ¼”-20 mounting points give LT units tons of options for attaching directly to your camera rig, and bi-directional Sony L-series or Canon LP-E6 pass-through battery plates. All LT units are compatible with Bolt 500 & 1000 devices and Bolt XT units.

Teradek RT Control – Pricing Varies Per Custom Kit

Forthcoming is the new button/rotary interface resembling a C700 which resembles a VariCam which resembles an Alexa… The idea is that the RED menu system is too complicated, and this addon interface will allow you to control your RED, easier. According to Pederson, this product is coming, “later in the Summer”.

Do wireless video systems pose a health hazard to operators?

Recently, the ICG released a whitepaper which detailed the health risks posed to operators who maintain close proximity to wireless transmitters. You can find a link to the paper alone, but essentially it’s the same as exposure to cellular microwaves. However, when transmitting HD and/or 4K plus camera lens and camera control the exposure becomes much worse. Minimal safe distance is about eight inches, but the closer you get the more damage you are likely to incur on an exponential level. If you’re an operator or an assistant, and you work in this world daily, think about how many hours a day and how many days a year you spend with your head in proximity to these transmitters. Of course, wireless transmitters are relatively new, so as of yet there are no studies on the long-term effects of exposure to these signals. However, the whitepaper clearly indicates that you are taking on damage by exposure to these devices.

The fact that sales and marketing personnel at Teradek, one of the leading manufactures of wireless video systems, aren’t prepared to answer a simple question on “best practices” or “safe practices” regarding their devices is alarming. Additionally, there is no warning label on the devices alerting users that there is any danger at all. My feeling is because none of the manufacturers who produce such devices are not compelled by the law to do so, you won’t find any safety information because to do so would be an admitting they are aware that there is a problem with the devices at all. Until the FCC or another government agency compels companies to fully disclose the risks to human health and issues requirements for safe operation, the pro video manufactures (like cell phone manufacturers or tobacco companies) will continue selling these products which clearly pose a risk to human health.

Do you work around wireless video transmitters on a regular basis? If so, are you concerned about your health, or do you think the risks are negligible? Please share your comments on our Facebook page at:
