Football time again

Once again BCARES is running a couple of D-ATV cameras at each CU home game. This year there haven’t been any new technical challenges. At events like this, we always station two operators with each camera for safety — one can be looking around if the other is focused on an incident. Here Jack K3UGR and Eric AIØJ keep an eye on the departing traffic after the game (OK, it’s pretty much all departed by now!).


D-ATV support for a DIA exercise

This Wednesday the Denver International Airport ran its mass-casualty drill at the DIA fire training center. BCARES members ran four digital ATV cameras to provide real-time situational awareness as well as record the event for after-action analysis. Three of the cameras were in the “infield” around a mock airplane and near where the casualties were placed; the fourth was a half-mile or so away covering the fire/medical staging area. We covered the fire response to the burning airplane as well as medical and “fatality management” (!) handing the casualties (nearly a planeload of volunteers with moulage).


This was another opportunity to run my portable quad receiver/processor. Thanks to the University of Colorado for the loan of their cameras and portable transmitters.

D-ATV support for the Milo event at CU

This past Wednesday CU hosted the controversialist Milo Yiannopoulos, a week after his visit to the University of Washington produced violent protests. We had about 150 protesters show up, but the excellent security team kept things safe and running.


BCARES provided two camera teams around the Math building, one on the roof and one on the ground. Given our location on the southeast corner of the building, the ground transmitter had to run on high power (3 watts) to bounce a signal off the nearby buildings and west towards the stadium antennas. Thanks to the new 20 Ah LFP batteries we got last fall, that was not a problem.

Presenting D-ATV to BES

Last week I gave a presentation and demo to the Boulder Emergency Squad (BES). They operate drones (“unmanned aerial vehicles” or UAVs) for county emergencies, such as swift-water search and rescue efforts. One issue they have is downlinking the video from the drone. We discussed how digital ATV could be used to backhaul video from the drone pilot/controller to a command post some distance away. This is needed because the drone pilot must have a line of sight to the drone, and so may have to move some distance away from a command post.

The presentation was largely the same as the one I gave last fall to the Arapahoe County ARES group.

TV support for public safety exercises

This past week I deployed a new quad DATV receiver box in support of public safety exercises.



Built around an 8×8 HDMI matrix, the box can substitute other video sources as inputs to the quad processor; below, we have two TV channels and the output from a drone camera on the monitor.


The switch also allows output of both quad and simplex pictures to any of several monitors or a laptop or other streaming appliance. During this exercise we experimented with streaming the quad box’s output over a private local wireless network.

Note that I’ve moved to using HV-120 receivers from Hi-Des; these are powered by 12v instead of 5v, have channel ID and manual channel up/down buttons on the front, and have a new, much improved remote control.


Thanks to Mark KØLRS who worked with me on the video setup.

BCARES from the Dalai Lama to Dead & Co.

BCARES again provided digital ATV support for special events at the University of Colorado, including the make-up visit of the Dalai Lama 6/23 and two evening concerts by the Dead & Co. during the Independence Day weekend.

BCARES camera crews provided real-time situational awareness for medical and law-enforcement issues as well as crowd and traffic control before, during, and after these events.
