Home security is like an onion – layered technologies make it harder to reach the center. (And make burglars more likely to cry as each layer unfolds!) Motion sensors, also known as motion detectors, are an excellent and essential level to your home security equation. Best rf signal detector Miami Beach Coral Gables.
Types of Motion Sensors for Home Security
Before we dive into the benefits of motion detectors, let’s just go over the basic types:
Active Infrared Sensors
Active infrared detectors emit a constant electrical signal that uses infrared light (heat) beams that connect to a light detector. If the infrared beams are interrupted, your detector sounds the Alert. Best rf signal detector Miami Beach Coral Gables.

Passive Infrared Detectors
A passive infrared sensor passively waits for an infrared event. When a heat source, like the human body, passes by, the sensor detects the moving presence and sounds the Alert. These are the most common sensors in home security. Best rf signal detector Miami Beach Coral Gables.
Active Ultrasonic Sensors
Active ultrasonic sensors use high-frequency sound waves (you can’t hear them) that work like a boomerang: These waves are sent out and then return to the sensor, reporting any suspicious interruptions in the sound waves (in other words, a human body obstructing the ultrasonic path).

Passive Ultrasonic Detectors
Instead of actively sending out sound waves, these detectors wait passively for a sound event, like shattering windows. The sound waves emitted by such an occurrence are what triggers a passive ultrasonic detector. Best rf signal detector Miami Beach Coral Gables.
Disable motion sensor
Disabling your motion sensors (to get a nighttime glass of water, for example) is as easy as keying in your code

Advantages of Home Security Motion Detectors
Motion sensors are an essential weapon in your home security arsenal. Your house Alert system is a lot harder to breach than Hollywood would have you think – and most prowlers are much less adept than your average blockbuster burglar – but still, layered security promises added peace of mind when it comes to your family’s safety. Best rf signal detector Miami Beach Coral Gables.
The sole purpose of a motion sensor – and its biggest benefit – is providing further security against burglars. Best rf signal detector Miami Beach Coral Gables. If your Alert system is somehow breached without alerting you to an open door or window, your motion detectors will sense your intruder and sound the Alert. This gives you time to reach safety while your Alert company calls for police assistance. Best rf signal detector Miami Beach Coral Gables.
And as for the oft-touted disadvantages, well, they’re mostly bad memories of sensors past. Today’s motion-sensing technology is very advanced, so you no longer have to worry about false Alerts from small or medium pets. They’re also easily disabled, so you can get up for a glass of warm milk in the middle of the night. Best rf signal detector Miami Beach Coral Gables.
Motion detector area

Motion detectors can cover almost the entire area of a room
A Note on Motion-Sensing Lights
Putting lights on a motion sensor is a very simple and effective – not to mention inexpensive – way to secure your property. You can place flood lights, garden lights, your front entrance light, and another outdoor lighting on motion sensors. Many indoor/outdoor motion sensor lights can be easily installed on your own (DIY). Best rf signal detector Miami Beach Coral Gables.
Motion-sensing lights provide several benefits:
Reduce Crime: Statistics show that well-lit communities have lower crime rates than neighborhoods with poor lighting.
No Place to Hide: When the exterior of your home is well lit, would-be burglars have no place to lurk or hide.
Warning Signs: If your floodlights suddenly go on, it’ll give you the chance to investigate or call the police.
Top 5 Highest Rated Motion detectors

What Motions Sensors Do
As the name implies, motion sensors detect and report motion – in most cases when nobody is home. That’s why they are normally not “awake” when you arm your system for the night. Best rf signal detector Miami Beach Coral Gables.

It’s not practical to put a door/window sensor on every window, and you usually don’t need to, since you can use motion sensors and/or glass break detectors (we’ll cover those in a future post) to get the protection you need more affordable. Plus, motion sensors have come a long way from the original models – much more reliable, and less prone to false Alerts. Best rf signal detector Miami Beach Coral Gables.
How Do They Work?
The early motion sensors were considered “active” devices because they emitted energy (microwave or ultrasonic) to see what was happening around them. There are some still some microwave sensors being installed in commercial spaces. Today the most common motion sensor uses Passive Infra-Red energy to detect heat given off by people (and animals!) – hence the name “PIR” often given to this device. Best rf signal detector Miami Beach Coral Gables.
Smart Technology
These are intelligent devices: they look for objects warmer than the normal background temperature, using a special lens to create “beams” of passive energy, and they also look for motion: when the sensor detects a “warm” object in motion across several infrared beams within a specified time frame – that’ what trips the Alert. If you want more of the science, here is a great link for the specifics. Best rf signal detector Miami Beach Coral Gables.
Where Are They Placed?
Best rf signal detector Miami Beach Coral Gables
The standard range for motion sensors in the home is 30-35 feet, and the coverage area is shaped like a large water droplet, with the skinny part at the detector. The ideal spot for a motion sensor is in a high-traffic area that an intruder would cross if moving about in your home or business: think front hallways, living rooms with big-screen TV, etc.
Maximizing “Catch” Performance
Motion sensors work better when intruders move across the beams, as opposed to approaching the sensor directly. The beams project out and down, to pick up anyone trying to avoid detection by crawling. Best rf signal detector Miami Beach Coral Gables.
Do not point them at a heat source like a stove or fireplace, and avoid pointing at windows that get direct sun. And, don’t use them in a space that gets so hot that the sensor can’t tell an intruder from the ambient temperature – like a garage in a warm climate.

Motion Sensors and Pets
Best rf signal detector Miami Beach Coral Gables
Today’s sensors are usually “pet-friendly” up to 40 pounds, which means they “ignore” cats and small dogs – unless your Siamese is downright acrobatic! That means that large dogs with the run of the house all day and night make it harder to use motion sensors – except for when you go on vacation, and board your critters. Best rf signal detector Miami Beach Coral Gables.
Wireless is the Name of the Game
As with other home security devices, the trend has been moving toward wireless technology for years. That means no drilling, no running wires, and a faster (and cleaner) installation process. Best rf signal detector Miami Beach Coral Gables. It also means that these sensors are easier to troubleshoot, to adjust, and even to move with you if you are fortunate enough to have a DIY Alert system. See this previous post for the rundown on why wireless sensor technologies are the new norm.
It’s true that every home Alert system I’ve seen over the past 25 yea
Best rf signal detector Miami Beach Coral Gables
rs has at least one motion sensor. Best rf signal detector Miami Beach Coral Gables. They work, they are reliable, and they should not cost a lot. Now you’ve got two Alert devices under your belt – the wireless door & window sensor, and the wireless motion sensor – and that brings us closer to being able to design a complete home security system. Best rf signal detector Miami Beach Coral Gables.
If you want to be notified when there’s activity on your property but you don’t want to invest in an expensive home security system, an outdoor motion sensor installed in a strategic location is an effective way to receive Alert alerts. You can use an outdoor motion sensor to be notified when a vehicle has entered the driveway, when someone unexpected is at the front door, or when a burglar is attempting to break in. Best rf signal detector Miami Beach Coral Gables.
There are several types of affordable outdoor motion sensors. Some units are stand-alone and wireless, which makes them easy to install and operate. Choose an outdoor motion sensor based on what you want to monitor and where you want to install it. Outdoor motion detectors. Best rf signal detector Miami Beach Coral Gables.
