Can it be used for spying purpose? What's the maximum distance it can pick up a human sized object with an identifiable resolution?

It doesn't give you that great of pictures that far away. You need a pinhole camera for what you are thinking about doing. But remember spying is illegal! !!

No, it cannot. Anything outside of th 2-3 inch range is out of focus. This product is a complete waste of money.

It doesn't fit under most doors but I guess it can technically be used for spying purposes with enough effort. There is never a time with good resolution, but you can recognize a human shape in any room.

It would only give you the distance from the device itself to the target, or direct line of sight distance. It doesn't calculate "drop" from a higher vantage point.

Not very, it is designed to only look at things inside a pipe. Things a few inches away were clear enough. Much further and it gets fuzzy. Works OK for what it is designed for. I was going to rig a brace with some strings running back to allow the camera to be pulled left and right (a little) while in a pipe.

You can get various degrees of magnification from a short distance away (I don't have it out right now to measure - lets guess about an inch) on up to right up to the clear plastic barrier; from that point if you cut the product into approximately a 1/2" diameter circle, then you can get further magnification up into this plastic 'shroud'. Obviously trying to scan along the surface will have to be what ever max magnification you can get outside the clear plastic piece. Note that there are no indicators that tell you what magnification you are at.

So far, it gives you the location, but I tend to find that the device is not accurate past 20-30 feet. So if you are using to track a person with some sort of cognitive issue, you will know the general area to look, but not the specific area.

Not really, you would have to get close to the suspect to get anything useful, not good for far away, not good for outside surveillance too. Good for indoor meetings.

Yes, i have two smaller dogs and it easily detects them teen feet away. Mounted 8 ft vertically.. Not Sue what sensitivity i have it on as the default worked great.

I would imagine there would be distance limitations with the device. Experiment!

It does pick up any light that is out there but at night, without any light source, it is hard to see. Not a big deal IMO since you you should not shoot at something if you cant see it....the main thing is that it actually works at 100 yards and is fairly accurate. I was surprised.

Sorry, we have no response for this question as we use it for scanning persons at security.

yes, it can be used for detecting human, ambient and other hot(maybe cold) object's temperature.

Absolutely. The optics is superb, its razor sharp and no chromatic abberation is visible. But keep in mind, it's a 8x power scope, so the angular resolution is of a 8x power scope too. You will can identify any bird with it, but no insects ;)

Depends on how deep they are. This will discover metalic objects perhaps an inch below the surface, but it's prime use is to "pinpoint" the operator closer towards the object he/she seeks that the metal detector has already found.

The spypoint will work fine. Make sure and set the reciever within range. They might find the camera but you can hide the receiver. Receiver does not receive all pictures from the camera.

The camera communicates wirelessly with the monitor. There is no wire connection, so the effective distance may be limited. I find about 75 feet to be the max. Highly functional camera because it is portable and can be moved from place to place. Usually good reception at night. Overall, we depend on this camera to watch our property.

Unless the scanner runs off a coaxial cable, I doubt it. This device is specifically for boosting signal in a long run of coaxial. It has some functionality in cleaning up signal noise, but again I doubt it does what you wish it do. There is other equipment specifically designed to clean up and boost signals transmitted and received by radio equipment. Ask a ham radio operator or equipment stores that service ham radio.

It measures distance by picking out the brightest object in the frame. I guess that's using a reflection but I don't think you'll like it for hunting if you plan to hunt in the woods. On cloudy days and in deep shade it just doesn't work.
