Awesome! This tool is pretty sweet, makes it very straight-forward. Is it downloadable? What other tools are you guys considering? (Please pardon my ignorance, as I was very late to the tool webinar last week, appointment ran over...my loss and my apologies.)
Nice, very nice. Keep up the good work !! :)

I'm trying Firefox and IE and the PTZ function in the scenes isn't working. Also tried reloading the pages.
This is cool....Great job :)
it looks great, thank you guys! is it possible to add the meters option for those of us not custom to use feet? Tks
12 MP.. ? Is that it? LOL.

This is very helpful John. Thank you for providing this tool.
Wow guys you are amazing, great work. If metric system also included that would be awesome.
Great, thanks for this! You should create a permanent link to this tool somewhere I think.
Any chance of a version in metric?
[Yes, we metric support is now live.]
Missing scene for Warehouse with long and high shelfing with dim light conditions.
A very nice tool indeed, any plans to make it metric ? or is there a hidden option ?
[Yes, metric support is now live.]
It's pretty good done camera calculator. Thank you.

John, I am using the following IE version and the tool does not seem to respond at all. Any ideas?
WINDOWS IE VERSION - 8.0.7601.17514
Ciper - 256-bit
Finally, something that will actually help us and our customers make the best selection. I know its early, but I tried it on my iphone with chrome and it works, a little. I would gladly pay a few a bucks for this as an app that I can use with pics that I've taken while onsite. Great jobs guys and thank you!
Thanks for the tool!
A suggestion - it appears that the scene images are some fixed size and resolution. Would it be possible to to define a regular camera picture FOV or modifier such that it could be uploaded and used to determine the ideal security camera FOV to define and document FOVs for installations? The application is taking a regular camera or cell phone and hold it where the security camera will be installed and use that image as a basis for selecting the final FOV.
Just a thought :)
How did you deteremine the angle of view for each mm setting? I have not seen an accurate lens calculator to determine horizontal fov in quite some time that was not made specifically by the camera manufacturer. For instance, you state that with a 1/2.7" imager, a 2.8mm lens should give you a 93 degree angle of view. But Axis for example uses a 1/2.7" imager in the M3005-V with a 2.8mm lens and they state you will get 118 degree angle of view. This is just one example, but many other cameras and manufacturers have varying horizontal angles of view listed that are different from typical lens calculator figures.
I have justed spent 10 minutes with this but it looks like an OUTSTANDING tool. I understand it is offered free at this point. Are you planning to keep it available as a free tool? If so, as a web-based tool, will you allow it to be linked on a member's website (of course, fully credited to IPVM)?

great tools, are you going to lunch one with the metric as unit system?
great stuff, how about doing it in metrics
Pretty nice, John. Good work.
Suggestion ... provide the ability to use our own image file.
Very nice tool and clean implementation. Maybe I'm missing something, but shouldn't "Horizontal FOV" be labeled "Width of Object" or "Width of Scene" and shouldn't "Angle of View" be labeled "Horizontal FOV"?
One other minor note. There are plenty of 5MP cameras with 2560 x 1920 resolution, but I don't recall seeing any cameras with 2560 x 2048 resolution, as listed in the Camera Resolution dropdown.
That looks great! Good work IPVM team! I look forward to the various improvements/changes others have already asked about.
Many thanks for adding the "Lens Selector" function. That is exactly what I was looking for.
Excelent tool. Is there any possibility to make a possibility to use it in meters as well ?
It will help a lot .

This IPVM Camera Calculator is cool and anig help, but I do not understand something. I thought that if everything else on the calculator remained constant (same Distance to Object, Focal Length, Horizontal FOV, Resolution, etc...) and all I changed was the sensor size, say going from a 1/2.7" sensor to a smaller 1/4" sensor, then I would have thought that the smaller 1/4" sensor would have resulted in a lower PPF, but I am seeing just the opposite occur, the smaller sensor is showing a higher PPF (again keeping all the other variables in the calculator constant). Can someone explain this to me, or is this an error?
1) Would be awesome if we could upload an actual picture and use the picture for selection.
2) Is there any way to make the tool full screen?
I beleive this will be the best comment in this string.........
Read the comments before you comment!
Next step is to support meters ...
I do agree, great tool, best I've seen yet. I did not notice if I can save and/or print the results. Just use a "screen shot"?

Some of us still use CIF. Would be great to add this in to the mix.
Will this be available as an iOS app? Take our photo and use the program.....?
IPVMU Certified | 08/06/14 06:36pm
Correct me if I'm wrong, but when uploading your own photo, would that not invalidate the PPF estimate? Not saying it still wouldn't be useful for estimating angles and such, but when you designed the calculator based on the example scenes, you knew what pixel settings those pictures were taken at and the amount of pixels used so you could adjust the calculater's formulas, right?
If someone uploaded their own picture, I would think they would have to be able to input what megapixel value the picture is and what horizontal and vertical angle the lens was if they wanted something close to a PPF estimate.
Metric support is now live. You can toggle between feet and metres anytime now - dropdown on the top right hand side of the calculator.
We'll also be adding 2 minor enhancements to it later this week:
- Adjust the scale of the graph to max out at 30 meter to be similar to the imperial one where we go to 100 feet
- Add a cookie that remembers if you select meters and keeps that set when you return to the calculator.
Also, notice that the calculator is now listed in the main navigation up top on every page for easier access.
An option to export a sample to give to customers as an example image would be great! I think it can help make the customers expectations more realistic... when they want to go with cheaper/lower res cameras, showing the difference in PPF can be a great tool!

awesome tool! Great work developing it and making it available!!
It seems if you set the sensor size and focal length which should fix the viewing angle regardless of resolution, changing the resolution setting is showing different viewing angles which would be confusing to users of this calculator. When changing the resolution the image shoulld become more or less clear while the viewing angle should remain the same for this comparison.

John & Team, this is a tremendous tool and represents what sets your work apart from all others. A paid app would not only bring tremendous flexibility for site surveys but frankly, paying $10, $20 or far more for an app this valuable wouldn't cause an eye blink. Outstanding product, the industry is in your debt!
Update: We now remember user preference for metric vs imperial, via cookie. Specifically, if you switch to metric and return on the same PC, it will keep it set to metric.
Also, we had a good idea from Ben Molloy to display the distances for key points on the scenes (for example the far corner on the intersection is 80' away). We are going to implement that and are looking to enhance that with something even more sophisticated / powerful (but I'll keep that a suprise for now :).
Finally, our plan is to release the much desired feature to upload one's own images / scenes end of next wek.
Two new enhancements to the calculator:
- By request, we now support one decimal place precision (e.g., 1.4 meters), something that's especially useful with the use of meters, as they are longer than feet.
- The graph now adjusts to 30.5 meters max displayed distance, maintaining the same scale as feet / imperial.
With those changes plus Friday's cookie to remember metric preference, I think we are all set on metric usage.
Now we are working on uploading own's own images and saving calculations (which will enable exporting, packaging them into projects, etc.).
May I know where in calculator can I input mounting height variable.
Great tool will be using it often to improve our viewing scenes and camera placements. Will be watching out for improvements.
Idea: Downloadable version with a scene capture button (instead of uploading a image) to use with a computer and then adjusting the camera features to suit?.
All good things take time, and what you have done so far is great keep up the good work. Thanks Heaps.
Minor technical precision bug in calculator. I think that there is a tiny rounding error, maybe in the AOV or an intermediate value, that manifests like so:
Starting with the calculator's default values,
2mm FL and 1920 pixel width = 8ppf
Then triple the focal length while reducing the horizontal pixels to one-third
6mm FL and 640 pixel width = 9ppf
IMHO, these should be equal, or am I missing something?

This tool is really cool and awsome. I found it very easy to use and quite streight forward. I whish I would have had such a sweet tool for use in designing locations and recommending the camera type to make the most on our investment.
Do we have the rights to frame set this into our corporate website for client self help?
A number of improvements have been added:
- There's a new parking lot scene that is just better, deeper, more lanes / cars.
- The scenes are now higher resolution so when you zoom in the image quality is sharper / cleaner.
- You can now upload your own image. We are doing some optimizations tomorrow but it fundamentally works and its an option on the right hand side of the scene selector. Try it out. Let us know.
Love this tool. Just tried to upload my own image and all I get is a black screen inthe viewing window. I have three images in the calculator and same results. Did i miss a step?
License Plate / Vehicle Entrance scene added.
This was our top requested scene. Here's what it looks like:
Just pick 'Vehicle Entrance' from the bottom of the 'General Scenes' list.

This may sound like a dumb question, but does anyone know the easiest way to determine what the horizontal angle of view is when a photo is taken with a handheld digital camera? I know it depends on the lens, zoom, etc... Is there any way to determine it after the fact? I have some photos that would be great to use for this tool, but I don't know what the angle of view was when the photo was taken.
Also does anyone know of a good free exif reader program?
IPVMU Certified | 08/27/14 06:14pm
Thanks for the clarification on angle of view. It helps.
I may be reading this wrong, but what does the 4000 horizontal pixel part indicate? Isn't it more like 5000? I think the recommendation is sound though.
Shouldn't the B's on some of these new Axis models be V's?
I would have to concur. Very sweet John.
in the lobby I chose a camera with 1.3 MP resolution to have a satisfying PPF of 45.7; the lens is wide angle (3.4 mm) to have a wide angle of view (70 degree); the distance to object (lobby doors) is 20 ft to have a suitable width of scene (28 ft) and a suitable PPF.
