 Infared wireless alert systemMay 29, 2010
By L. Walley
For my situation...this product works great. A few false alarms, but I dont think thats the fault of the unit. Its just picking up motion from something I havent figured out yet. This unit does not come with an A/C adapter...it should. I will eventually get one. Ive had the patrol about a month now and I am very pleased with it. The only reason I dont give it 5 stars is the lack of an A/C adapter. Of course it would cost more, but I would have liked that option. Possibly another of their products does come with one. So far the batteries are lasting, time will tell how long, and certainly that is going to be dependent on how many times it goes off. There is no volume setting..you only have 3 settings...high...low...and off. That is not an issue for me. For the money this is a great product. It performs for what it is intended for and works for what I wanted it for...which is to alert me when someone enters my drive way. I wanted this unit because my car was recently broken into..I do expect that in the future this unit will alert me to intruders.

Alert me of Amazon drop-offsSep 30, 2010
By Amazoned
I bought this after reading the mixed reviews and decided to take a chance. In my situation it worked pretty well with few false alarms here and there. I installed it to a beam on the front porch, which alerts me anyone standing in my front door that didn't ring the bell. This usually applies to drop-off of smaller items from Amazon, and other carriers. Now whenever a packaged is dropped off without ringing my bell, I will know immediately when I'm home!
As for sensitivity, my porch is pretty much blocked off/closed off in most directions so it only has a small area to detect. Only one direction has a tree 30 feet in sight. There has been false alarm whenever wind blows hard enough to cause the branches and leafs to move. I understand this device has pretty good range, so that's understandable.
Do make sure you put in batteries that have similar charges left (or brand new). I first put any available batteries (including one that's 3/4 drained), and it wouldn't receive the signal from the motion sensor consistently. This warning is given in the small instruction manual, but who reads that first!

 Be Alerted by the Driveway Patrol Wireless SystemSep 05, 2010

U.S. Patrol Driveway Patrol Infrared Wireless Alert System
The Driveway Patrol consists of two compact wireless units. One of them is a transmitter and the other one is the receiver. The transmitter has a motion sensor, and will send information to the receiver indicating that someone or something has activated it.
The transmitter encases the circuitry and one 9-volt battery in hard, durable plastic. The battery fits neatly in a small compartment accessible from the rear of the unit by removing a cover which is secured with two small screws. A rubber gasket prevents moisture from entering through the battery compartment. It is adviseable to remove the battery when the unit is stored for long periods. Included in the package are two screws which can be used to secure the unit to any wooden support of your house or mailbox. The sensor has a range of about 400 feet.
The receiver is also constructed of durable plastic. It operates on three "C" cell batteries, which can be easily accessed by sliding the cover towards the bottom of the unit. In addition, the receiver can also accept power from a 4.5 volt DC charger plugged into a wall outlet. When the transmitter signals that its beam has been interrupted, the receiver gives off a pleasant chime in two tones. The chime's volume can be adjusted for high or low.
Before permanently installing the transmitter, you should test various locations until you are certain it will not be activated by stray animals or vehicles passing along the street.
I researched the availability of the Driveway Patrol on the internet, and found that the most reasonable price ($14.60, plus shipping) was offered by one of the merchants on Amazon.com. I highly recommend the Driveway Patrol, especially because it can alert you not only about visitors, but also unwanted intruders.

 Doesn't Work & No Customer SupportDec 27, 2010
By McGap
I received one of the Driveway Patrol units for Christmas. We started working with it to see what would be the most effective range. The distance between the units was no problem. But the sensor only worked if you had the thing about 1-2 feet away! Not particularly useful.
I called the company (Jobar) and was told that they had no customer support, that you just have to take it back to where you got it and follow their return policy, I presume. I asked if they were not the manufacturer, and was told that they were just an importer and that the unit was made overseas and there was NO one to talk to!
So, we're sending the unit back, but I can not recommend this product. Seems like if you are lucky, you might get one that worked properly or not. Any other products they sell should be suspect as well. It's a case of let the Buyer Beware!

Sunlight Drives Me CrazyJun 12, 2011
By 1-JoHn_1:9
After reading all the comments about false alarms in so many units I ordered two units. One came from the east coast and the other from AZ. Both arrived on the 4th day following my order placement. Each unit appeared in good working order when batteries were installed. (Note: When you turn them on there is a 15-30 second time frame to stabilize.) I placed one inside and one outside using one receiver. (Note: All driveway patrol units have ONE frequency that they use.) More on the in a minute.
After an hour I started having an increase in false alarms and realized that the unit outside was in direct sunlight and I placed a shade over the top. All false alarms went away after the 30 second reset period. In order to confirm this sensitivity to sunlight I switched the units and had the same result. The next thing I wanted to know as the actual area of coverage. Using the indoor unit I determined the area to be approximately 15 degrees wide for each unit. The farther away from the sensor you are the wider the area of coverage. (like a slice of pie) Sensitivity distance is dependent on the object size and speed of transition across the sensed area. More importantly, the difference in temperature (called the Temperature Differential or Delta 'T') between the local area (Ambient Mean Temperature - AMT) and the moving object has the greater influence on how each sensing unit "Decides" when to trigger an alarm.
For example: A person running directly across the path of the sensitive area will trigger an alarm far more often where-as a cat strolling across at an angle may not. Both of my units sensed my walking at a casual pace 50 feet away from the units. And both units triggered an alarm at 100 feet during the cool evening and night time hours from a passing car.
Next, I wanted to determine if the "400 foot" transmitting distance was actually achievable. After several attempts to send a trigger 400' I'm convinced that 400' feet is the theoretical distance that the signal strength can be recognized by the receiving unit. This distance was not achieved under normal operation. But I was able to get an alarm signal at that distance with a parabolic reflective surface behind the receiver which helped focus the weak signal. Note: this distance is based on line of sight and is reduced by signal absorbing objects such as walls, chain link fences and other solid obstructions.
In the end I believe that the greatest influence for false signals is the sun. But in chatting with other owners I've also become aware that in urban environments there is a possibility that one or more of your neighbors may have a system just like yours. If you've never had any false signals and all of the sudden you start getting them it very well may be that one of your neighbors has just installed one or more units and you're able to pick up their transmitter. I say this because of the specifications that indicate that there is only ONE frequency for every Driveway Patrol sold. If you have neighbors with these installed within your reception range, you're more than likely to get their signals and they will be picking up yours. Keep that in mind when considering the purchase of the DP system.
SO... What's my final take on the Driveway Patrol motion sensor? It does what it claims to do, almost. Set-up is important and proximity to other systems can be a big pain. If your in an area with a lot of activity these things will indeed drive you crazy. The constant beeping (aka Radio Shack entrance chime) of the false alarms will make you turn it off. The volume has TWO settings... Loud and LOUDER. They aren't discrete and some people will call that a benefit. Others won't care and the rest of the noise sensitive world will hate them. My solution was to wrap the lower half of the receiver in a layer of foam held in place with rubber bands. That took care of about 50% of the volume and from there on the system has been great.
So (1) Keep these out of the sun (you may even need to make an enclosure that will offer ample protection from the heat and light of the sun)
(2) Place your transmitter at a right angle to the general direction of travel
(3) add some sound deadening material to reduce the noise to a bearable level.
(4) Hope that your neighbors close by don't already have these installed.
If you can do this you'll be able to know when folks come to visit whether they are expected or not.
