The human eye can see (maximum acuity) the difference between two lines .35mm apart at 1 meter, so maximum human visual acuity can be described as .00035 of the distance.
Really it's a relationship between size and distance, for instance if an object is 10cm^3 (that's 10cm wide x 10cm long x 10cm high) you would be able to distinguish it from the surrounding environment at a maximum distance of about 28571.42 meters away. That's 85714 feet or about 15 miles.
This is, of course extremely relative to the person we are talking about, the example above is someone with extremely good eyesight.
What else can I help you with?
Why should you have a Motion Detector for outdoor lights besides the fact that it saves energy and money?
Burglars and others with less than honorable intent do not like to be suddenly illuminated since his activities typically depend on stealth. A sudden change in the lighting causes people to look, and the burglar will typically want to avoid having anyone notice the guy breaking into a house or business.
How do you Wire a motion detector with three way switching?
To wire a motion detector with three-way switching, connect the motion detector to the common terminal of one switch. Then, connect the traveler wires from that switch to the common and traveler terminals of the other switch. Lastly, connect the motion detector to the common terminal on the second switch. This setup allows you to control the motion detector from both switches.
How does a LED light works in a motion sensor detector?
Two pairs of Infrared LEDs are used as motion sensor detector. The first one is wired to emit LED and the second is wired to transmit a signal when it receives an infrared input. this infrared is reflected back to the receiving LED and then the signal is produced. This signal can be used to open sliding doors, turn on a light or set off an alarm.
Motion detector security lights won't turn off?
In most motion sensor switches you will have three wires. A black, white and red wire. The black and white (neutral) are used for the electronics in the sensor. These connect to the incoming black and white power. Connect the lamp across the red and the white (neutral). When the sensor detects motion the red wire becomes "hot" and the light will go on.
What is a commonly used alarm device for monitoring motion indoors?
A commonly used alarm device for monitoring motion indoors is a motion sensor or a motion detector. These devices are designed to detect movement within a specific area and trigger an alarm or notification. They are commonly used in home security systems for added protection.

Why do motion detector lights stay on?
Motion detector lights may stay on due to various reasons such as sensitivity settings, environmental factors like wind or animals triggering the sensor, or a malfunction in the sensor itself.
What are the benefits of installing outdoor motion detector lights in your home?
Installing outdoor motion detector lights in your home can enhance security by deterring intruders, increase safety by illuminating pathways and entrances, and save energy by only turning on when motion is detected.
Should you leave your outside lights on at night?
Get your outside lights hooked up to a motion detector. The lights will come on only if it detects motion very close to your home. It is not very expensive to do.
Why are my motion detector lights not working?
There could be several reasons why your motion detector lights are not working. Some common reasons include a power outage, a blown fuse, a faulty sensor, or a problem with the wiring. It is recommended to check these potential issues to determine the cause of the problem.
How do motion detector lights work to detect movement and activate illumination?
Motion detector lights work by using sensors, such as infrared or microwave sensors, to detect changes in the environment caused by movement. When movement is detected, the sensors trigger the light to turn on and illuminate the area.
What are the benefits of installing motion detector flood lights in a home or outdoor space?
Installing motion detector flood lights in a home or outdoor space provides increased security by illuminating the area when motion is detected, deterring potential intruders. Additionally, these lights can help prevent accidents by lighting up pathways and stairs, and they can also save energy by only turning on when needed.
What are the best features to consider when choosing an outdoor motion detector for home security?
When choosing an outdoor motion detector for home security, consider features like range, sensitivity, weather resistance, adjustable settings, and compatibility with your existing security system.
What device do you use to detect motion?
motion detector
Can a kid make a trap with only string a motion detector and a Nerf gun?
Yes, and you wouldn't need the motion detector.
When was a motion detector invented?
The first motion detector was invented in the early 1950s by Samuel Bagno. He developed a device that could detect motion using a technology called ultrasonic waves. This early version of a motion detector paved the way for the more advanced versions we use today.
Why do they say to only use incandescent lights in security lights with motion sensors?
Incandescent light are the only type of light that has a filament. The filament is the the little piece of wire that glows where the electricity passes through it. All other lights are gas filled. Most motion detectors need to pass a small amount of electricity through the filament to work. The motion detector uses the filament as a neutral wire. The time lag to get a florescent bulb to light up would create too much delay and negate the use of the motion detector. The filament will light up very quickly.
