Always be aware when invited guests or unwanted trespassers visit your property or enter a restricted area. This motion sensor notifies you when motion is detected up to 30ft away, so you never have to worry about people sneaking around your property without you knowing.

You can even adjust the settings for a smaller environment and safeguard an important area of your home or business. The system has the ability to expand and hold up to three motion detectors connected to one parent unit at once so you can easily protect more areas of your property. With the AL101, you can feel comforted knowing when your children come home at night or when someone enters a private or restricted area within your business. Ensure your safety and peace of mind with this advanced motion alert system. Always be aware when invited guests or unwanted trespassers visit your property or enter a restricted area.

Good, basic wireless driveway alarm system,
Customer Video Review Length:: 5:30 Mins
In the current economic climate, many people are tightening their belts and becoming increasingly concerned about their loved ones at home. Others just want the peace of mind from knowing their homes are alarmed against unknown visitors. There might even be a few folks who want to prepare for the rumored upcoming zombie apocalypse. In all of these cases, installing a basic home alarm system is a good initial step to take.
There are many home security systems available, and they run the gamut of price and features. One very simple, inexpensive security system is the Defender Wireless Driveway Alert System.
In my video review I show the basic operation of the Defender Wireless Driveway Alert System, and even demonstrate the system being used as it might be deployed around your own home, but here I’ll just summarize some of the main points made in the video and give a few more details where needed.
The system comes with one motion sensor (with mounting bracket), one receiver with AC wall plug, four AA batteries, and a user manual. The wireless motion sensor runs on four AA batteries and the receiver runs on four AA batteries or AC power. The receiver has a volume control, three LEDs for the three security zones that can be alarmed, a port to connect the receiver to an external 3-wire alarm or other security system, and a switch to turn on/off the LEDs (for example, if you are trying to conserve battery power).
Basic Operation:
First, place the sensor in the desired location. They say the sensor can be placed indoors or outdoors, and you just aim the sensor so that its cone of detection covers the area you want alarmed. The sensor has two sensitivity levels: 15′ and 30′. So maybe if you are alarming a room inside your house, you might want to use the 15′ setting; if you are guarding the driveway or sidewalk, then maybe you want to use the 30′ setting.
Second, place the receiver inside where you will hear and see the alarms, within 500′ of the sensor.
Third, wait until something crosses into the sensor’s cone of detection. When something is detected, the receiver will sound a series of beeps, which you can adjust with the volume control, and the LED of the corresponding sensor will flash (up to three sensors are supported by one receiver). If there is no more motion within the sensor’s range, the alarm will stop after a few seconds.
Performance:
As you can see from the video, the unit does what it is designed to do: it detects vehicles and even people moving with the motion sensor’s cone of detection. There is little customization possible with this system though–no programming or automating the timing of when the alarms are active and inactive, for example, and you can’t customize the audio of the alarms other than changing the volume of the beeps. But for the price, it is a good basic alarm system, especially for alarming your driveway to warn you of approaching vehicles or people. Or zombies.
So, this security system may or may not be what you are looking for, but either way I hope this review has helped you in making your decision.

|Easy to use, simple design and interface,
Defender AL101
The Defender AL101 system is composed of up to 3 transmitter/sensors, and 1 receiver unit. The transmitter/sensors are water resistant units that are affixed to a wall/post using a clip with 3 self-tapping drywall screws. The water resistant units really just depend on some rubber seals/o-rings, I would not recommend put it in a place that might see a lot of rain or moisture, the manufacturer recommends placing it under an awning or cover.
The range is advertised at 15 ft for low sensitivity and 30 ft for high sensitivity. The sensor cone is 30 degrees, and I found that its sensitivity was dependent on how fast the object moved. I creeped an object slowly across the sensor’s field of view and it didn’t trip it until it got right in the center of its path.
Once tripped, the receiver will sound an audible alarm which is nothing more than a series of beeps from the receiver. The volume adjustment is very unlinear. At the lowest setting, nothing comes out of the speaker. Just a tiny bit more, and the volume is at a comfortable level. A little more and it starts to get ear piercing.
Here are my gripes. The receiver is nothing more than a small box with a big power button in the center, and it just beeps when one of the sensors is tripped. You don’t know which “zone” until you find the receiver and look at it. There is no shut-off timer or programmability to provide you with automated activation of sensors at certain times. If I put the sensor in the front of the house, it will go off when I walk or drive around my property. I’d prefer to activate it when I go to sleep since no one I know will be walking around the outside of the property. So with this current receiver, I have to remember to turn it on or off.
The sensors rely on four AA batteries and is advertised to have a 6 month operating life with an average of 10 alarm trips a day. You can swap these alkaline batteries for NiMH but that means recharging them every few months. The receiver has a 9V AC adapter option or takes four AA batteries.
As a full-time home security device, the Defender falls just a bit short with the lack of programmability. It might work well as a garage sensor to see if anyone is leaving/entering your garage or perhaps as a rudimentary sensor to tell if you’re coming too close to the wall when parking it in a garage.
The range between the sensor and receiver is fairly long, which is a good thing but I’d prefer some programmability to turn them off or on at preset times.
Pros: Very simple, easy to use
Cons: Very simple device
Overall: 3/5 stars

|A simple solution for blind driveways,
Because of the design of my home, I cannot easily see my driveway. This product allows me to know when someone is coming up the driveway so that I can be better prepared for it. The remote unit has two sensitivity settings so that you can adjust sensitivity.
While some reviewers have commented that it picks up animals, the answer is, yes, it does. The best solution to that is to install it perpendicular to the driveway because animals more frequently cross over the driveway instead of traveling up and down it.
I also have other Defender alarm products and am happy with them. This product can be integrated with the alarm, but I can only think of rare circumstances where someone would want to do that.
