Here's what that looks like in the i OS version of the app. This way you can switch back and forth between visible and IR images. More important: I like having access to a thermal camera at just about any time I might need it. However, since I previously looked at the FLIR One I guess everyone wants a comparison. If you just need an IR camera, the Seek Thermal is cheaper and will get the job done (at a higher resolution).
Since the visible and IR cameras are on opposite sides of the phone, you can get some parallax. Playing With the Seek Thermal —————————–I've had the chance to carry this IR camera around for a while, I like it. If you have an Android phone, you should probably go with the Seek Thermal (since there isn't a FLIR One for Android).
For the temperature readings, the sensor can detect values from -40°C to 330°C. The IR camera can "see" things through two different mechanisms.
It could see the light that an object emits from it's temperature (this is what you want).
An Infrared Review ——————But what does an IR camera do? Here is a more detailed overview of the physics of infrared light, but I will give you the short version. Before you turn it on, it is room temperature and produces light.
So the infrared camera take the light that you can't see and displays a false color image where different colors correspond to different temperatures (mostly).
Browsing Amazon for hidden cameras is a little disconcerting.
Cameras are disguised as alarm clocks, power adapters, smoke detectors, photo frames and even water bottles, most of them wireless and battery powered.
The matter typically comes down to where you can expect to have a "reasonable expectation of privacy." There are certain spaces you would expect to be private, like bathrooms, dressing rooms, hotel rooms and locker rooms, and surveillance cameras placed in such areas are typically illegal.
(However, if a sign informs you that you're under surveillance somewhere like outside a dressing area in a store where there are cameras to discourage theft, the cameras are typically considered legal.) In spaces that aren’t private, like browsing a shopping mall or walking down a city street, cameras are typically legal whether they're hidden or not.
