The new FW is out! It is version 2.1.0 ! A new protection has been added to protect against menu hack!
But not against resolution hack, I think! The menu files are now crc protect, CRC ??
The update adds the advertised new features (manual scale, two new image modes: blending and alignment) for the E8 (only for E8?).
I think, for the menu hack, crc protection must be deleted from applaunch.dat. But question is, this file can be changed? It looks like a protection in applaunch.sgn ...
Who wants to test it?
@Mike: You should add it to the first post.
Maybe they just got bored and wanted to stir things up to push the post count here over the 5000 mark...
Post #5000
That is all.
Mike, I took a screen cap of your tear down film and put the ball array layout from the datasheet on top of it.
Following the traces I think I fond the JTAG connections.
Is it useful to investigate this further?
PS I found a good clamp for the Flir.

I have the hack 1.9.8 FW with Taucher Beta3 Menus and Zoom activated. To me all those new FW are a try to contain the hack rather than to fix or implement new functions.

Seems to be a trend and not only confined to some industries.
Basically, I want to know if the Acti E77 camera can be allowed to have higher frame rates if not bound by the firmware?
The Acti E77 is a new 4K resolution surveillance camera that has 30 frames per second at 1080p resolutions, but then dips to only 6 frames per second at all other higher resolutions.
From the Acti E77 spec sheet:
6 fps at 3648 x 2736; 6 fps at 3648 x 2160; 6 fps at 2592 x 1944; 6 fps at 2048 x 1536;
30 fps at 1920 x 1080
How can this camera only get 6 frames per second at all these other resolutions if it gets 30 frames at 1920 x 1080?

Those CCTV cameras are limited by computational power for encoding the video and limited by data-bus throughput.
Usually they are developed on a SoC according to a reference design (~1000 USD - just enough to keep private people out).
The SoC has a finite computation power, so take it as "bytes/sec" limited ... either many bytes per image -> few MPIX images per second .. or few bytes per image and many images per second.
Overall data/bitrate ... more or less constant
pixel clock alone will reduce the frame rate to 7.5 fps when you quadruple the resolution in raw mode, but then it needs to process the image which is limited by the internal bandwidth, reducing the frame rate more and it has to be synched to the host so 6fps sounds actually pretty impressive for a 4K sensor.
As for the 1081 mode, the chip might not let you use arbitrary resolutions, just some predetermined ones.
Just think that at higher res, you are quadrupling the work load, upping the clock 4 times to compensate might fry it,I mean you are talking 400% overclocking
I'm guessing that it uses the full 3648 x 2736 sensor in other modes and it's limited by how it's hardwired as in it either it uses half the rows and columns or it uses it all.
simplified math because there is more to it that this:
(1920x1080)x60Hz / (3648x2736) = 6.232687 Hz

Are the teeth inside the clamp soft or hard? Do they indent the E4 handle?
