Traffic cameras are an opportunity for drivers to make travel decisions based on road conditions. Knowing if there is congestion, an incident blocking the freeway, extreme weather or other condition can help you decide to forego travel or detour the area, making for an easier commute and safer roadways.
Travel and road conditions change rapidly, and drivers are in the best position to perceive such conditions and adjust their driving accordingly. Those relying on the foregoing information do so at their own risk, and neither the State of Nevada, the NDOT nor any of their employees or agents shall be liable for either the accuracy of this information nor any actions taken in reliance thereon.

Digital microscopy and microscope cameras and software are fantastic additions to the world of microscopy. However, there is nothing more frustrating than not being able to view an image on your computer monitor from your digital microscope. Below you will find some troubleshooting tips for viewing live images on the camera or computer monitor from your digital microscope.Is your microscope beam splitter engaged?The microscope beam splitter directs light up the trinocular port to the camera. When the beam splitter is not pulled out or engaged, the light will not travel up to the camera and you will not be able to view an image at the camera. You will find the beam splitter on the side of the head of your microscope. The beam splitter will either be a switch or a lever you can pull out and push in. Do you have a specimen under the microscope and in focus?Before you try to view images through the camera or on your computer screen, make sure that your sample is under the microscope, the light is turned on and it is in focus. Many camera sensors are sensitive and if your image is not in focus the camera might not pick it up.Particularly on a stereo microscope - is the light on?Many times when you look through a stereo microscope without the light on you might still be able to see the image. However, cameras require extra light in order to be able to pick up that same image, so make sure you have a brightly lit sample under the microscope.Are objectives clicked into place and caps removes off stereo objectives?If you are using a high power compound biological microscope, make sure that your objective lens is clicked all the way into position. If it is slightly between positions the image will not be projected up to the camera properly. Many stereo microscopes come with a black protective cap that is screwed onto the bottom of the body to protect the lenses. Make sure this cap is removed before using the microscope and trying to view samples with your digital camera.Digital Camera Software Adjustments:Each microscope digital camera uses different software, but some of the troubleshooting tips are similar across many camera interfaces.
1) It's currently a staging driver. Meaning that it *could* work with *some* Raspberry Pi camera. As I understand, there's two completely different versions of the Raspberry Pi Camera and only one is mainlined in the staging folder.
to keep it short.. at the moment it doesn't boot and we're still not sure what it breaks.. I think it's DTS related, or we miss something in the configs, or one of our patches breaks it... We also tried the asus way of implementing camera support via isp10 (the old deprecated isp driver from rockchip and this seems to be not practicable)... I built more than 20 (I really don't remember how many SD cards I flashed...) images trying to bring up the camera. So feel free to join the party.. I decided that I need a break from the tinkercam...
@chwe does the imx219 work? i just have this one. Thx -chips.com/wiki_Rockchip-isp1 -linux/gstreamer-rockchip-extra -linux/kernel/blob/release-4.4/drivers/media/i2c/imx219.c -linux/kernel/blob/release-4.4/arch/arm/boot/dts/rk3288-miniarm.dts -linux/rk-rootfs-build -linux/rk-rootfs-build/blob/master/overlay-debug/usr/local/bin/test_camera.sh -linux/kernel/issues/72
I've never tested it. From the original dts, it's properly described (whereas the OV5647 misses the port description as described in the github issue you see in the other thread). So building a new image with the needed drivers, replace our dts (create patch = yes) which has some adjustments and build an Image could be worth to test. In case this doesn't work set GCC to
At present we don't have the isp1 driver working, so neither RPi camera is functional. I have both cameras, but have not gotten the DT/kconfig right to make it work. There is also the issue that both cameras use the same resources, so they can't both be defined in the DT without overlays.
It should be plug and play. It works on ASUS images ( =CSI-camera). But there is some bug that is preventing it from working in Armbian. It might have gotten fixed already, you can try it and see if it works.
(What I mean is that there has been a patchset applied recently in the development default image, that may have fixed the bug. But I have been the whole day trying to find my Rpi camera, without success, so I couldn't test it).
The Tinker OS kernel is using a now deprecated driver, As we're using the Rockchip kernel directly, we should work to the new driver, which requires *a lot* less "tweaking" to work. In short, I haven't had the time to get this working, what with actual bugs on the table to deal with. Like I said, I'll give it another go shortly. There were some adjustments to the drivers, so we'll see.
not with the config we use at the moment, since activating the needed drives will end in not booting images anymore... Even if the camera is not connected.. In case you start to dive into it.. Which cam will you use? Just have a look to the github issue to avoid you doing common mistakes.. I don't have this image anymore to test it with the imx219, but as for my ov5647 I never got it working on their own image. So, I never saw a tinkerboard with their new isp1 driver and a working camera. But maybe, it needs some fresh mind working on it, since I might be to dump and miss something obvious.
no, that's the original.. and actually also present in ours, cause we don't install the needed drivers, it is (at the moment) useless. In case you go for the OV5647 camera, you have to change it to something like:
Well, yes, that is the driver for the camera, now, how it interacts with the Rockchip ISP driver is a question, I assume our issues are purely kernel config related, but Hell if I know what the config should be, it isn't documented very well.
Camera support is one feature of one SoC probably possible with one out of 32 kernels armbian supports (and has to maintain) populated on one out of 74 boards armbian supports.. We already 'wasted a few ours' to get it basically working (and failed)... I opened a thread specific for the ISP issue, shared everything needed that someone could join it to figure out what's wrong but it seems that most people who want the camera working aren't really interested in getting it working. So, guess why I lost somehow the interest, dealing with it? I'm not the super duper kernelhacker, it's mostly me wasting a bunch of time try to understand things or try things by try and error...
Smart televisions offer a lot of cool features, including internet access, streaming apps, and built-in cameras and microphones. However, because they are always connected to the internet, those TVs can be a potential risk.
Hackers who gain access can control your TV and change certain settings. Using built-in cameras and microphones, a smart and capable hacker can spy on your conversations. In November 2019, the FBI issued a warning(Opens in a new window) about the risks of smart TVs to your privacy and offered several recommendations.
The FBI noted that TV manufacturers and app developers have the ability to listen to and watch you. But a potentially more serious threat comes from bad actors who gain access to your unsecured television and take control by changing channels, adjusting volume levels, and even showing inappropriate content to children. At worst, they might turn on your TV's camera and microphone to spy on you, or use that access to find a backdoor into your router and other connected devices.
What are the potential risks and hazards for smart TV owners from hackers?Hyduchak: The risks come from anything involved with microphones, cameras, and sensors. Data mining based on what you watch and where you are is also valuable in the data marketplace, so these things become a risk too.
Carson: Smart TVs are basically computers that are running an operating system. The same risks that apply to computers also apply to smart TVs. Most smart TVs have cameras, a microphone, and a file system. If a cybercriminal gains access to your smart TV, which is likely connected to the internet, it would mean an attacker can see you through your camera, listen to your conversations, and steal your data. An attacker could also use your smart TV to latterly move to other devices on your home network. This includes your laptops or other personal devices, including network storage.
In a post-pandemic world, our webcams have become an essential part of our lives. If your PC's camera isn't working, it can be really stressful. Fortunately, getting the camera on your computer to work properly doesn't require much tinkering.
As a preventative measure, you should stay on top of all updates as they come. If you miss an update, you should download and install it as soon as possible. We also recommend making sure that the drivers for your camera are up to date, as well.
Check if the camera is enabled. Many laptops come with a physical kill switch that disables the camera physically. We advise that you check to make sure that you haven't disabled the camera yourself by accident. 2ff7e9595c
