Here is the DHCP capture file. You always get that malformed packet which seems to confuse Windows initally.
I don't know the Linux equivalent but there are Windows command line tools (i forget the name of) you can use to "replay" packets captured in a Wireshark grab back out an interface. That is sometimes useful when debugging when you have a known good trace.
Does anyone in Europe received the Flir E4 from the company conrad.de (and web pages Conrad.xx)
I think I listed the various USB ID's somewhere earlier on... I'll just paste it here...Code: [Select]RNDIS and UVC : 09cb:1005

I noticed a spot on my lens, which I tried to clean with a Q-Tip soaked in some isopropyl alcohol and canned air. The spot is still there but now I have a small circular spot on my thermal images as well It's quite hard to see after powering up the E4, but gets more prominent after some time. That circle is shown to be a little warmer than the surrounding environment, except when I point the camera to a hot surface, then it seems to be colder.
Since any dirt on the lens should be out of focus (?), did I somehow manage to move dust or oil droplets inside the housing to the sensor surface by blowing on the lens?
I now contacted Conrad about that missing battery, since the web shop (by mistake?) promised that 2 batteries are included by the time I ordered. Now they corrected their article description, but I'm still waiting for an answer
ISTR reading that the E8 comes with a spare battery and standalone charger - that may be the cause of confusion.
Really, 320x240 is still only thumbnail resolution. Soon, thermal cameras will not only be sold as tools, but as toys -- 20 megapixel thermal cameras will be sold at Wal-Mart for a few hundred dollars. It might take a decade, but it will happen eventually.
For that to happen the companies would need to change the perception of one from being just a tool to a more consumer-oriented product, which I don't see as happening easily. With visible light cameras it's a lot more obvious why that happened - people like to take pictures (and video) of things as a complement to their memories, something they can easily identify with. But I doubt the general public would be as interested in taking thermal pictures and/or knowing the temperatures of things, because human eyes don't see into the infrared already (not to mention TIC pictures make people look odd and creepy.) The price of optics and sensors also has to come down a *lot* more than it is today, down to visible-light camera prices (example: 640x480 30FPS modules for <$10), and in that case the companies would probably want to keep more of it as profit rather than lower their prices.
It could happen as just a side effect of the continued development into visible light camera sensors and optics.

Probably not. But there may have been a coating on the outside of the lens, and your cleaning removed a portion of it.
Just speculating.

A Germanium lens should be cleaned with non solvent based fluids. I recommend the use of the standard eye glass cleaner that contains no IPA or solvents. Such cleaners are safe on plastic lenses and TIC lenses. IMHO you should not use the little packets of lens tissue type glasses cleaners as these can be abrasive. Use a Microfibre cloth.

Flir has a guide for lens cleaning:

I don't know if the new E series is applicable though.
You can make your own cheaply and easily
