FAQ
What is the maximum and minimum FOV of the DNNCam?
The focal length range and imager size of the DNNCam are as follows: Focal Length: 4-12 mm Imager Size: 1/1.8" Using a tool like https://calculator.ipvm.com/, we can calculate the minimum and maximum FOV to be: Minimum FOV: 33° Maximum FOV: 84°
Getting Started
This article will include links to relevant documentation/articles to get started with a new DNNCam or DNNNode. Note: The information in this guide is intended for production devices and not developer devices. Network Setup Boulder AI devices ...
How do I determine which direction is North/South from my count sensor configuration?
When viewing the directional data for a count virtual sensor, you may notice that the directions are labeled COUNT_{OBJECT}_NORTH and COUNT_{OBJECT}_SOUTH. These directions are determined on how the line was drawn. After adding a sensor line, you ...
How can I improve the image produced by the DNNCam in low-light situations?
We suggest the following configurations to increase performance in low-light scenarios: Decrease zoom Increase/open the iris (100% is fully open) Use a low gain setting, like 1-10 Use a high exposure setting (i.e. 1/960 min, 1/15 max) Turn off ...
Can two DNNCams detect objects on 4 approaches to an intersection?
Yes. With an assumed 30ft mounting height, the diagonal relationship of two DNNCams can cover the lanes and crosswalks of a 4-way intersection. See the image below:
How does a DNNCam or DNNNode connect to a traffic signal controller?
The DNNCam and DNNNode communicate using NTCIP protocol directly to a traffic controller. The controller can then take the API data and run it through their algorithms. The physical output of our devices is a Class D or better Ethernet cable (Cat ...
I bought a DNNCam/DNNNode prior to the release of the Boulder AI Platform, how can I get my device up to date?
Unfortunately, if a device is flashed with any L4T Jetpack package (Ubuntu) then it will not be visible by the Boulder AI Platform. Please contact support to determine the best solution to update your device firmware.
What are the default network settings of a DNNCam or DNNNode?
By default, the network configuration will be: Hostname: 'baidnn-<serialNum> ' For devices with BAI OS v1.4 and earlier, the hostname will just be 'baidnn' IPv4 DHCP: Enabled Link Local Addressing: Yes When searching for the device using a network ...
What is the default login to the Web UI?
To access the Web UI, navigate to the device's IP at port 5000 in a web browser (Chrome/Firefox recommended). Web UI Address: http://<DNNDeviceIP>:5000/ Default Username: admin Default Password: baidnncam Note: After your first login, you will be ...
How do I power my device?
The DNNCam and the DNNNode require an 802.3at PoE+ (IEEE 802.3at) power source delivered over a Class D (Cat 5e) ethernet cable or better as specified in ISO/IEC 11801.1995. While the devices will power up with 802.3af PoE, this standard provides ...
