what is camera optical field / range of vision

It's a great little set up I've got two cameras that covers my whole backward as well as neighbors just place in strategic position give you little less than 180 great for price

I have 1 camera on my carport and the other in front of my house. The cameras cover these areas just find. The optics are very good for the price of the system. I am very satisfied with the system.

The user guide says that the "field of view is fairly small. It is approximately equivalent to the field of view through the telescope when looking through a typical (i.e. not wide-field) 5mm focal length eyepiece." So maybe 200x ?

Hi - I got out the manual in order to answer this question. It is an electronic viewfinder. Hope this helps. By the way, this is a great camera!

There is no view finder. The lens is a wide angle type and I've not had any issues with it not picking up a good field of view.

I can see my fence (in pure darkness; no lights) at 65 feet from camera. The image is a bit grainy, but you can easily see a body or movement - you will not be able to see facial features. At about 30 feet, images are clear for me. One thing that impacts the image is the angle at which the camera points. My camera sits under the soffit, and points downward at about a 25-30 degree angle and gives me decent view up to about 30 feet. At that angle, this causes the LEDs to point downward, thus "lighting" up that area, while sacrificing distance. If I pointed the camera towards the long distance, I get better imaging with distance. But still, at 100 feet, no luck with facial features. If you have a street light nearby, this helps quite a bit and I can get the 100 feet. My second camera on other side of house has a streetlight nearby and I can see past 100ft. Hope this helps.

The camera is fixed and has a narrow field of view. Quality is good, but you need distance to get a good feel for what's in front of camera.

Here are some useful links to sort out field of view. You may want to look at the 4-9mm model if you seek a wider field of view. I have the 4-9mm on my garage looking across the street and the 8-20mm looking at my front door. Overall good for the price.http://www.homesecurityguru.com/cctv-camera-lensesVideoSecu Outdoor 700TVL Day Night Security Camera Built-in 1/3" SONY Exview CCD II EFFIO-E DSP 65 IR Leds 4-9mm 3X Zoom Lens for CCTV DVR Home Surveillance with Power Supply and Security Warning Sticker CJZ

No you dont. The term 'focal length multiplier', and I am assuming you are referring to this number, does nothing to your focal length. It is a horrible term. It is your FOV (field of view) that changes.

Assuming you mean the Milky Way, here's a good article : http://www.lonelyspeck.com/lenses-for-milky-way-photography/ and it shows you the field of view you can expect with the lens.

Hello, the 10x digital zoom is the same in all POV modes. Check out my youtube vid for an idea of what a 10x zoom is like. The object is around 15 yards away just for reference. Cheershttps://www.youtube.com/watch?v=33YENYtaxZI

Not the same range. A smaller sensor gives you more telephoto and less wide angle. I am sure there is a conversion somewhere.

As far as I can research, it is 16.4 feet the close focus. A closer minimum close-focus distance usually means forfieting magnification. A closer minimum close-focus distance often means an reduction in overall image clarity.

I don't know how to determine the field of vision in terms of feet or yards. My impression was that I saw what I expected, both in range and detail. In fact, I was pleased with the range and the details when I first tried it. It took me a few minutes to get my bearings because this is the first night vision device I've tried. Perhaps to put it in perspective, I stood on my back deck and looked into the approx. 2.5 ft wide by 4 ft high window on my shed which is about 20 yards away--I could a rope inside the shed, window panes, and other objects inside the shed. So, at about 12 to 15 yards I could just see the 2.5' by 4' window missing (blocking out) only a few inches on the height.I hope this helps.

You really don't want to get closer than 3 feet from your subject. There's an equation you can use for 3D: multiply the interocular (the distance between the middle of the lenses) and multiply by 30. In the case of the TD10, the interocular is 31mm. 31x30=930mm, or 36.6 inches, or just over 3 feet.The Panasonic Z10000 has a macro mode that works really well, but it is a pricier camera.

Hi there, This sensor features a 60 degree viewing radius from dead center. The field of coverage will increase the farther you are from the sensor (Up to 39 ft.) but the sensor is designed monitor small areas 10 to 20 feet from the sensing eye (so as to minimize false alerts). In other words there is very little peripheral vision the sensor offers.

I think the standard view is approximately 45-55 degrees - at least on most of my older cameras. I just did a rough measurement of this field of view and it seems to be about 90 degrees.
