Chronos User Discussion / Future Camera Idea Krontech: Chronos 2K but using a 2/3 sensor for lower cost
« Last post by B.H.V on December 20, 2023, 06:57:57 AM »Just an idea. Some of us like the smaller 2/3 sensor form factor as we can use modern sharp 0.95 and 1.2 lenses (Laowa Argus, Meike and Nokton) at their wider aperture receiving more light into the sensor while keeping a greater depth of field for easier focusing compared to larger sensors. And I'm guessing by using a smaller sensor and some other cost cutting measures (ie. cutting the maximum record time to 3 seconds which would require less RAM), the camera can be more affordable. Looks like GPixel has a 2/3 2K sensor (see below). Just a thought. Was thinking this can maybe be around $5000-6500 as the lowest affordable option for Krontech. At this price point, I think more people would buy.

Some key specs:
"GSPRINT4502 is a 2.5 Megapixel (2048 x 1216), 2/3” (φ10.7 mm), high speed image sensor designed with the latest 4.5 µm charge domain global shutter pixel. It achieves more than 30 ke- charge capacity and less than 4 e- rms read noise, with dynamic range of 68 dB which can be expanded using a multi-slope HDR feature. Utilizing an advanced 65 nm CIS process with light pipe and micro lens technology, the sensor achieves >65% quantum efficiency and < -92 dB parasitic light sensitivity.
GSPRINT4502 can achieve extremely high frame rates up to 3460 fps in 8-bit mode, 1780 fps in 10-bit mode or 850 fps in 12-bit mode, all at full resolution. With 2×2 on-chip charge binning, full well capacity can be further increased to 120 ke- and frame rate to 10,200 fps. GSPRINT4502 supports vertical and horizontal regions of interest for higher frame rates. GSPRINT4502 is perfect for high-speed applications including 3D laser profiling, industrial inspection, high speed video and motion analysis."

Chronos User Discussion / Re: Chronos 1.4 Footage Thread
« Last post by B.H.V on December 20, 2023, 06:50:27 AM »I use the 7Artisans f/0.95 35mm MFT lens. I usually film at f/0.95 or f/1.2.
I have a Meike 35 0.95 lens as well and it's pretty sharp at 0.95! My Meike 50 0.95 is a bit soft low contrast wide open but not too shabby. It sharpens up at 1.2 and up. One of the benefits of the smaller 2/3 sensor is we can use these wide open apertures as the DOF is greater and more forgiving in getting the subject in focus.

General high-speed discussion / Re: ISO 1000 to 16000 how?
« Last post by aquamiddle on December 18, 2023, 05:27:56 PM »The ISO sensitivity of a camera indicates how well it can catch light. The camera can record weaker light and is more light-sensitive the higher the ISO sensitivity. In order to catch as much fluorescence signal as possible, high sensitivity is usually desired when using fluorescence microscopy applications.

General high-speed discussion / Re: Connecting to Windows SMD Network Storage
« Last post by hummingbirdography on December 18, 2023, 12:04:32 PM »Hi,
I'm having difficulty connecting to network storage that I have setup on my Windows 10 device. These are the basic steps I have followed.
1. Assign IP address on laptop ethernet network card to 192.168.1.1 with netmask 255.255.255.0
2. Assign IP address on Chronos camera to 192.168.1.2 with netmask 255.255.255.0
3. Set "Unidentified Network" to private (it defaults to public network).
4. Create folder to be shared.
5. Right Click-> Properties -> Sharing and share to user. This outputs my Network path of \\compute1\\Chronos_Footage
6. I then go into the Chronos 1.4 camera and go to SMB Share and set SMB Share to 192.168.1.1/Chronos_Footage/
I get the error "is not reachable!".
I'm not sure what is going on here and any help will be greatly appreciated. I think the guide to connect to a Windows Network Drive might be out of date as well?
Thank you,
Dustin
I think Windows 10 defaults to a version of SMB greater than 1.0, which isn't supported by the latest 0.7 firmware.
https://learn.microsoft.com/en-us/windows-server/storage/file-server/troubleshoot/detect-enable-and-disable-smbv1-v2-v3
I ran into a similar issue with my NAS which uses SMBv3 and had to SSH into the camera to get the service logs for more troubleshooting clues.

General high-speed discussion / Re: Connecting to Windows SMD Network Storage
« Last post by strawcreak on December 18, 2023, 01:15:14 AM »It seems like you're encountering difficulties connecting to network storage on your Windows 10 device. Let's troubleshoot the issue step-by-step:
Verify network connectivity: Ensure that your laptop and Chronos camera are connected to the same network (192.168.1.x) and can communicate with each other. You can try pinging the camera's IP address (192.168.1.2) from your laptop to check if they can reach each other.
Firewall and network profile: Make sure that the firewall settings on your Windows 10 device are not blocking the network connection. Additionally, ensure that the network profile for the "Unidentified Network" is set to private, as you mentioned.
Folder sharing permissions: Double-check the folder sharing permissions on your Windows 10 device. Right-click on the shared folder, go to Properties, then Sharing, and verify that the appropriate user has access to the folder.
Network path: Confirm that the network path you're using is correct. The format should be \\compute1\Chronos_Footage.
SMB Share settings: Review the SMB Share settings on the Chronos 1.4 camera. Ensure that the IP address (192.168.1.1) and the folder name (Chronos_Footage) are correctly specified. Check if there are any additional settings or requirements mentioned in the camera's documentation.

Chronos User Discussion / Sony C-Mount adapter Plate for older Chronos models
« Last post by B.H.V on December 14, 2023, 09:35:07 PM »I see the new 4K12 and Q12 have the option for a Sony E mount adapter plate. Can the 1.4 and 2.1 get that same option as well?

Chronos User Discussion / Re: 100,000 FPS with the 2.1 as previously advertised
« Last post by hummingbirdography on December 13, 2023, 06:25:07 PM »When I purchased my 2.1, it was under the expectation that the camera would be able to reach 100,000 FPS per advertising on Kron Technologies website. To my knowledge (and please correct me if I am wrong), the limit for this camera is still around 24,000 FPS. Is there a way to increase the FPS even if it is an unadvertised method.
@rdemyan yes, it is possible. Take a look through this thread for instructions:
https://forum.krontech.ca/index.php?topic=661.0
I was able to configure my 2.1 to support 114,504fps at 832x8 resolution, and 85,324fps at 832x16 resolution. Technically the h.264 encoder works, however I suspect saving in one of the other formats would yield better results for unusual resolutions.

Software Dev / Re: Will there ever be a 100,000 FPS version again?
« Last post by hummingbirdography on December 13, 2023, 06:20:29 PM »Actually, the following code for step #6 from the instructions @sanjay posted is better, because it will only use the vertical resolution when it is less than 64.
nano pychronos/pychronos/sensors/lux2100.py
change MIN_VRES = 96 to MIN_VRES = 8 on line 37
change
numRows = 64
fSize = self.getCurrentGeometry()
to
fSize = self.getCurrentGeometry()
numRows = min(64, fSize.vRes)
on line 656
save and exit the file with Ctrl + O then Ctrl + X
One other minor issue I found is there might be a strange horizontal dot pattern at the bottom of the image if you press the 'Max' button for the framerate on the back of the camera while using an unsupported resolution. Try setting the framerate to something lower, and the dots should go away with a black calibration. Then return to the recording settings menu and press the 'Max' button for the framerate. The dots should go away for that setting as well with this second black calibration.
