My favorite feature of this camera is its built-in crt viewfinder which gives a far far far more detailed image than can be recorded with a composite video out connector. It must be seen in person to be appreciated. The image looks like a very very fine mesh grid matrix. I manually counted/estimated the individually seen pixels as 400 approx Horizontal and 300 approx Vertical - this is what is shown through the edge-to-edge rectangle cropped viewfinder - as a rectangle image whereas the sensor sees a round image (even higher pixel count) - which is output to the video out connector simultaneously.

I own a Xedar XS-410 Thermal Imaging Camera which has a 400x300 pixel area size approx and is recorded in 720x 480 onto DVD. It uses a Vidicon tube which gives it a very good quality image and sensitive to very small heat diferences.
Comparable models from other vendors - their camera requires liquid nitrogen to be fed to keep the vidicon tube cooled and are much larger/bulky in size. My camera requires no liquid nitrogen and operates from a standard 12v battery- which keeps costs low and makes for a very portable unit which can go where-ever I go.
Most smaller handheld thermography thermographic cameras of today are solid state and only have a resolution of 100pixels to 300 pixels (other mfgs still today produce Entry level to mid-level low resolution images).
This Xedar XS-410 camera surpasses many (but not all) of the newer models in resolution and sensitivity and framerate. Thermal imaging tubes are better than solid state sensors. My Xedar XS410 is one of a series of thermal imaging cameras produced by the mfg Xedar Corporation - some of these models include Pyroscan, Pyroelectric, XS-408 (with XS-212 lens), XS-420, and my very own XS-410 (made in approx year 1988) Each model included a different set of technology and size. Due to the tube technology - I must always be concerned with keeping the camera lens moving - otherwise a image can become "burned" permanently into the sensor - if left there too long. Hot items like flames and sun should never be looked at with this camera for long period of time. It is ver sensitive to small variations in temperature - for example trees apear black and snow is white in outdoors winter. Did you know trees are much warmer than outside temps? It offers an incredible view of the world and insights about buildings, equipment machines, electronics, repairs, maintenance, nature etc. I'm glad to have it.
Things I have used this camera for
1. Auditing a house or business or machineshop for areas of the building which need extra insulation or sealing against the weather or areas which contain moisture.
2. Identification of trouble areas on electronic circuit boards - which have failed or are expected to fail soon. For example IC chips which are running excessively hot are prone to failure.
3. Temperature differences in lakes, earth, mountains, and other nature.
4. Identifying parts of an engine which are running hot - for example V Twin motorcycle engines in which one cylinder is running too hot.
5. Customers send in their part to be thermally tested
Let me know what I can do for you - I try to be reasonably priced.
The video it prduces is recorded on a standard VCR or DVD recorder. It is a grayscale image in which hot areas are white and cool areas are black. It has a toggle switch where I can put it into photo negative mode where hot areas are black and white areas are cool. It is a real time live image just as any camcorder would produce - except it produces a thermal image showing only thermal true IR infra red live video. A dark room / night makes no difference to this camera as it sees heat not light. It works just as well outdoors as indoors in total darkness or full light. All it needs is a fully charged 12v battery and video recorder and a 15minute warmup time since it is tube based. It is much more sensitive than the smaller low resolution handheld units of today. The 15minute warmup time is its only drawback and the superb image quality is worth the wait. It has a big lens which brings in alot of IR light and sensitivity is very good. I have read some complaints abut newer handheld cameras which are low resolution and see "blobs of" colors which are hard to distinguish what you are looking at. With my camera I can see fine details whether it is a transistor/IC chip or a cat or a pipe or missing insulation - the image is very clear and distinguishable as a nice clear image on my vintage vidicon tube-based camera.
It can see structural elements behind walls (missing insulation, studs, uneven areas, etc) I have heard of people using thermal imaging cameras for ghost hunting (I've never done that) You may think of a purpose that is not listed here - let me know I'll consider it.
I'm not selling my camera. I'm advertising for my thermal
imaging service - let me know what I can do for you.
This camera requires no liquid nitrogen or other consumables
so I can offer reasonable pricing.
