Uses for a Driveway Motion Detector

A driveway motion detector should be part of your security system. In fact, as part of a complete motion detector system (i.e., indoors and outdoors), it’s the lynchpin of a complete security system!

After all, it’s the main device used in the detection of an unwanted and unauthorized presence in residential and commercial applications. When it detects moving objects within its area of coverage, it automatically performs a task to alert owners about the unauthorized presence. The task can be turning on the lights and/or sounding an alarm.

This is the case with Mr. Beams MB393, a weatherproof wireless battery-powered LED spotlight with motion sensor.  The driveway motion detector can be installed indoors or outdoors depending on the need.

Notable Features

The Mr. Beams MB393 is a three-pack driveway motion sensor package with residential and commercial applications. Both homeowners and business owners have expressed overall satisfaction with its performance from installation to use, even in its maintenance. Of course, the assumption here is that the driveway motion detector was installed and used according to recommended instructions.

Due to its wireless design, you will find it fast, easy and convenient to install the unit indoors or outdoors. You just need a screwdriver to screw in the unit into its mount as well as 5-10 minutes of your time. You don’t have to hire an electrician since it’s a DIY project without the hassles of wires and wiring systems.

The mounting hardware is already included in the package. Your job is to find the best location for mounting it, such as on the garage’s exterior wall. You can also make a customized mounting post for it, if necessary.

According to the manufacturer, this is a weatherproof unit so it can be installed outdoors. Even the best O-ring for weatherproofing cannot withstand the harsh natural elements. Putting silicone tape around the O-ring’s cover opening can extend its life.

The three LED spotlights provide 300 lumens of illumination, a sufficient amount for most residential and commercial uses. When the lights are activated by motion, you can easily see what or who activated the trigger.  You can then decide on your next step, such as calling the police against intruders.

By the way, the 300 lumens is among the brightest among wireless spotlights today. But don’t worry about the power consumption as the spotlights run on 4 D-cell batteries. The batteries are purchased separately from the main product.

Under normal use, each set of batteries can last for a year or so. Normal use means 8 to 10 activations per day, on average. Since batteries are affordable, the cost justifies the benefits from the spotlights’ optimum functioning.

Each LED spotlight can cover 400 square feet, which means all three spotlights will provide 1,200 square feet of area. This means that even large driveways can be lit up when the spotlights are activated. You want to be able to see as far as possible to determine who or what activated the sensors.

The spotlights automatically turn on when motion is detected within 25 feet of the sensor. The automatic function obviously happens in the dark. The spotlights also automatically turn off after 20 seconds after the detected motion stops.

During the day, the light sensor comes on. You don’t have to worry about the spotlights being activated during daylight, which wastes battery life, due to this feature.

The spotlights are mounted on an adjustable head, too. You can rotate the head 180 degrees, as well as pivot it in up-and-down and side-to-side movements. You can focus the spotlights on the darker areas of the driveway, for example.

The bottom adjustment will tilt the light from side to side. The upper adjustment will adjust it up and down.

For these reasons, the Mr. Beams MB393 is a great driveway motion detector. You can also install it in patios, decks and yards with the intention of exposing thieves taking advantage of the night’s darkness.

In summary, the features of Mr. Beams MB393 include:

  • Dimensions 4½ x 3½ x 6½ inches
  • Weight 11 ounces
  • LED spotlights with 300 lumens
  • Motion sensor turns on the spotlights when motion is detected
  • Automatic turn off of lights within 20 seconds after the object has stopped moving
  • Weatherproof casing
  • 400 square feet of coverage for each spotlight


Pros of the Product

The Mr. Beams MB393 motion detector with spotlights has the following advantages:

  • Battery-operated driveway motion detector
  • Easy and fast installation with just two screws and a screwdriver
  • Durable casing
  • Weatherproof and waterproof housing
  • 25 to 30 feet of motion detection range
  • Affordable price
  • Energy-efficient operation
  • Automatic turn on and turn off depending on the motion detected


Cons of the Product

The Mr. Beams MB393 has a few disadvantages based on reviewers including:

  • Intermittent motion detection wherein the lights will stay turned off even with movement detected within the range (i.e., blind spots)
  • Batteries should be changed, which can be a hassle in a busy schedule
  • Unit cannot be connected to a burglar alarm system


Who Is It Best For?

The Mr. Beams MB393 is suitable for homes and businesses that require a lightning-based security system. Homeowners usually mount it on or near the driveway to illuminate the path, whether welcome or unwelcome people are coming over at night. Business owners use it as part of their theft deterrent measures, especially at night.

But emphasis must be made that motion-activated lights shouldn’t be the only component in a complete security system. Lights alone will not drive away thieves and burglars from the property – alarms, locks, and perhaps security guards are also necessary.

But if the motion-activated lights are used in monitoring the activities in homes and businesses, then the Mr. Beams MB393 unit will suffice.


Verdict – Should I Buy It?

Yes, the Mr. Beams MB393 is a great buy provided that you’re only looking for a set of motion-activated lights. This should ideally be part of a complete security system integrating alarms and locks, instead of being the be-all and end-all of it.  Your house or business will be more lighted but it isn’t sufficient to drive away thieves and burglars.
