Can you put security cameras in your car in California? The answer is yes. More and more drivers in California are considering getting dash cams for their vehicles after more crimes have been caught on these devices.
Security cameras with a motion sensor that calculates changes in pixels will still be able to detect movement and record through glass or a glass window.
Where can a camera be hidden in a car?
Good options include sunglass clips on the overhead flaps, hulu or bobble-head sculptures on the dash, large objects hanging from the rearview mirror (like fuzzy dice) or reusable trash bags that hang behind the front seats.
Can night vision cameras see through glass?
The short answer is yes, night vision can see through glass. In fact, both active and passive devices rely on light waves that pass through the glass to form an image, so if there’s enough ambient light to see through the window or windshield then a night vision device should have no problem as well.
Glass. One of the most effective methods to block IR is to conceal behind glass; if you are okay with carrying around a pane of glass, great!

Can cameras see through tinted cars?
Police say thieves can use cell phone cameras to look through tinted windows. Police in Memphis, Tennessee, recently warned residents that it doesn’t matter how dark your windows are tinted — when you put a cell phone in camera mode up to the glass, you can see right through.
Can infrared cameras work through glass?
Can thermal imaging see through glass? Fun fact: glass acts like a mirror for infrared radiation. If you point a thermal imager at a window, you won’t see anything on the other side of the glass, but you will get a nice reflection of yourself in thermal.
Can a security camera see through a car window at night?
The short answer is infrared light, particularly in the wavelength that is used for night vision in security cameras, can pass through clear white glass windows used in cars.
Can infrared sensors see through glass?
An infrared signature is essentially a heat profile. The PIR sensor cannot “see” through glass because this signature cannot travel through it. This means that, in most cases, any object moving outside a window will not trip a PIR motion detector mounted inside.
The transparency of glass to visible light makes it the most common way to let light into a building. But because glass is also transparent to near-infrared radiation — windows also let in heat, giving rise to the well-known greenhouse effect.
What material can infrared pass through?
Infrared radiation in this range will not pass through many types of material that pass visible light such as ordinary window glass and plastic. However it will pass through, with some attenuation, material that is opaque to visible light such as germanium and silicon.
Do sunglasses stop infrared?
Vuarnet lenses are guaranteed to provide 100 percent protection against UV rays, and while most sunglasses don’t offer any protection against infrared rays, Vuarnet lenses are also designed to absorb up to 98 percent of infrared radiation as well.
How do I block near infrared?
Any electrically conductive material will block IR. The greater the conductivity, the greater the blocking. Aluminum foil will kill all IR, bot high range and low. Most plastics allow IR to pass through.
Can aluminum foil block infrared?
Any electrically conductive material will block infrared radiation. The greater the conductivity, the greater the blocking. Food wrapped in aluminum foil. Since aluminium foil is a highly conductive material, it will kill all infrared radiation.
Does aluminum foil block infrared radiation?
The surface of aluminum has the ability NOT TO ABSORB, but TO REFLECT 95% of the infrared rays which strike it. Since aluminum foil has such a low mass to air ratio, very little conduction can take place, particularly when only 5% of the rays are absorbed.
Glass, Plexiglas, wood, brick, stone, asphalt and paper all absorb IR radiation. While regular silver-backed mirrors reflect visible light waves, allowing you to see your reflection, they absorb infrared radiation.
How far can infrared camera see?
There is no practical limit to how far a thermal camera can see through a clear line of sight. The Moon for example is often visible when not obscured by clouds (water vapor absorbs IR energy).
Can a cell phone camera see infrared?
The cell phone camera is more sensitive to light than human eyes are, so it “sees” the infrared light that is invisible to us.
What camera can see through walls?
The latest version of a ‘sense through the wall’ camera, developed by Israeli company Camero, can detect any object, wire, or even shallow breathing of a human, from a distance of over 50-meters (164 feet).
