How Do I Change The Channel On A Bunker Hill Driveway Alert
Wireless Driveway Alert System
from Bunker Hill Security
A driveway alert system can exist a squeamish addition to a standard abode security system. If your home layout includes a long driveway, a perimeter alert volition requite you advance notice that someone is budgeted.
Information technology's best to employ a stand-alone driveway sensor , every bit opposed to connecting it to the main alarm system. Animals, dust and blowing debris and other environmental factors can cause false alarms for any outdoor motion detector. Tying a driveway monitor to the main system volition likely cause more headaches than it solves!
Bunker Hill Security Wireless Driveway Alarm
The Bunker Hill Driveway Alert shown hither is available online as well every bit through ane of my favorite stores, Harbor Freight Tools.
1byone offers an identical driveway organisation called Driveway Patrol. Aside from the brand-proper name label, both the Bunker Loma and 1byone systems seem to be made by the same manufacturer.
Both versions of this driveway alert organization are wireless, and consist of two units. The starting time is a passive infrared motion detector, which also includes a built-in transmitter. It senses movement and sends a signal to the 2d unit of measurement, a wireless receiver. The receiver gives an audible two-tone alert, along with flashing LED's.
The Bunker Loma transmitter is powered past a unmarried ix-volt battery, and signals a depression bombardment condition with a steadily lit LED indicator. The 1byone transmitter uses (iii) AAA batteries.
The receiver/sounder unit operates on battery power using (3) C-cells. Information technology also gives an LED alert if the batteries go depression. Optionally, a plug-in ability supply tin can be used to ability the receiver (purchased separately). The jack is 5.5mm bore, with center terminal positive.
The Air conditioning adapter shown here is by Ideal Security, simply any-make plug-in transformer rated at five or 6volts DC and a 5.5mm connector, center positive should work fine. I utilize a unit of measurement made past 1byone rated at five-volts, which they also sell with their version of the driveway alert system.
Update: Since this was originally written, 1byone now offers a version of this organisation with (ii) motion sensor units and an included plug-in transformer to power the receiver. It costs a fleck more than the basic system, simply if you can use a second motion detector, it might be a better pick for you.
The transmitter is conditions-resistant, so information technology can be located outdoors without a cover. Because I alive in Arizona, I ever prefer to mount outside equipment under an eave or overhang if possible. This offers some protection from the sun, and volition give any device a longer service life.
The receiver unit is not weather-rated, and should be placed indoors on a table or shelf, or wall-mounted.
Driveway Warning System Set-upwardly and Testing
After unpacking the drive mode alert components, I inserted the appropriate alkali metal batteries.
Annotation: The small screws for each battery compartment are non captive, and are easily dropped!
Remove and install them over a table, towel, etc. to avert losing them.
I the installed the wireless driveway alert system transmitter at one side of my garage overhead door, facing the street. For testing the receiver was placed nearby so I could hear it when information technology tripped.
Both wireless driveway monitor units mount with screws and keyed slots, making installation pretty simple.
Discover also in the photo above the small-scale stickers showing the channel number on each unit. This set is coded to Channel 13 ("CH13"). If you lot desire to use multiple Driveway Alarm sets triggering together, just be sure to buy units with matching channel numbers.
Driveway Warning Transmitter Detection Range
The spec sheet included with the unit lists the rated detection distance at xxx anxiety, although it repeatedly "caught" me walking at a distance of about 45 feet. This means it should easily sense the motion of a vehicle at that range, maybe a scrap more.
The horizontal field of view is listed at 40 degrees, which matched what I saw. This is fairly narrow, compared to a motion light or standard alarm motion detector. Most domicile security motion sensors take a broad-angle detection design of ninety-150 degrees. And so, what does this hateful?
If y'all have a broad driveway (about two cars wide or more than), the alert system transmitter should exist mounted facing beyond the driveway. All infrared motion sensors are more sensitive to motility across the detection blueprint, so this volition give you the virtually reliable operation.
Facing the driveway head-on, the driveway alert transmitter may not sense a vehicle approaching unless it lines upward directly in front of the sensor.
Driveway Alert System Manual Range
The manual altitude of the wireless driveway alarm is listed in the specs at 400 feet. To examination this, I carried the driveway alert sensor away from my house, leaving the receiver inside at its normal location in my dwelling office. In order to hear when the receiver was triggered, I fix a cell phone next to it. I carried a second cell phone with me, and called the kickoff phone then I could listen in.
The driveway alert sensor tripped the receiver repeatedly every bit I walked along with it. Equally I got further down the street the point grew weaker, and the trips became intermittent. I walked back and forth a fleck, until I got an thought of the usable range of the arrangement.
The maximum altitude at which I could trigger the wireless receiver at all was nigh 160 yards, or 480 feet. This exceeds the 400' promised in the paperwork for the system, but was not consequent.
For reliable triggering every time, I had to be within a distance of 140 yards, or 420 anxiety. This notwithstanding beats the advertised range, and should be adequate unless you have a very large property.
Conclusions for the Bunker Hill Wireless Driveway Alert System
Overall, I'm initially impressed with this wireless driveway alarm system.
For one thing, I wasn't expecting anything special from a driveway alert organization at this price ($29.99 regular toll, under $20 on auction, or with a handy Harbor Freight driveway alarm coupon). I wouldn't have been surprised if the alert system had limited range and/or sensitivity to motility.
Instead, I institute that not only were the rated ranges accurate, but as well very skilful for the intended purpose of the system.
A detection altitude of thirty' is reasonable for driveway security systems, and this unit did that and more. I fifty-fifty had to aim the sensor unit downwardly to reduce its effective range for my 33-foot long driveway.
Even more impressive was the radio transmission range, which I found a footling surprising. In my feel, well-nigh manufacturers of radio-frequency devices usually quote "open up-air" ranges, significant nix tin be in betwixt the transmitter and receiver. For my tests the receiver was within my firm, which is of slump-block construction. Brick, block, and other masonry materials will reduce radio signals to some extent.
In my case, the Bunker Hill Security system worked at or just beyond the specified distance. Your mileage may vary, depending on the structure type of your domicile, the actual distance between units, etc.
For all-time results, always test wireless devices in their intended locations earlier y'all begin drilling holes and mounting them.
The Lesser Line…
If yous're looking for some type of driveway bell or alert system, this Bunker Hill system may be simply what y'all need. Information technology'south an inexpensive perimeter alarm organization, and easy enough to install with just a screwdriver.
Cheque dorsum here for time to come updates on the Bunker Hill Driveway Alert Arrangement. I'll written report my findings on battery life, and whatever other developments that may come up upward.
Initial install date: April, 2013.
Update: October, 2013
Replaced nine-volt battery in transmitter unit. This means about a 6-calendar month lifespan for ane battery, with the unit being tripped most 6-8 times per day. Receiver battery nevertheless going stiff.
Update: March, 2014
Replaced nine-volt transmitter battery. This fourth dimension, the battery held up for merely about four months. However, during this period nosotros had solar panels installed on our habitation. All of this extra activity caused many more "trips" of the motion sensor than normal, then this probably cutting down on battery life.
The receiver is however on the original battery; though to exist fair, I often plow the unit off when I'm moving around the exterior of the house a lot.
Update: August, 2014
Replaced transmitter battery. Receiver is even so on original battery.
