Portable Motion Sensing Perimeter Alarm for Camp and Tent
Portable Motion Sensing Perimeter Alarm for Camp, Tent, Home, Car, Truck or Hotel.
One of our best sellers ! We have sold hundreds for a variety of uses - probably the most cost effective and versatile security tool you can buy. Also check out its big brother with a remote control pad (sold in sidebar).
Useful in camp, for construction sites, the shed out back, hotel rooms, anywhere you want to setup an impromtu motion sensing alarm to attract attention and scare away intruders. Deploying multiple units with varyious delay settings only adds to the fright amd confusion for intruders.
Can also be used in autos, trucks, storage lockers, school lockers, dorm rooms - anywhere you want to protect.
This alarm device will let you know if people, or animals (bear, moose, raccoons, etc.) are visiting your campsite or nearby area.
The alarm mode provides a super loud noise alert noise (rapid beep beep beep - 105 dB loud - it hurts) to scare bears and other critters away.
Alternatively it has can be set in a "Chime mode" that is quieter (ding dong like a digital door bell) and more discrete - just letting YOU know something is in range, and not waking everybody up.
Use in conjunction with the Motion Sensing Light (sold in the sidebar) for even more effect. Lights, sound, more lights, a second alarm sound on a longer delay - just makes for a bad, chaotic scene that will scare away unwanted intruders.
Since we are a camping company, We first sourced this portable alarm to provide added security on our camping trips. We wanted to know when someone or something is moving about camp. Choose from gentle Chime notification or super loud 105 dB alarm sound. Keypad on body lets you set your personal arm / disarm code.
The Alarm is battery operated so you can take it anywhere and position it to monitor in almost any direction.
Some customers have found other uses for this alarm. Fumigation companies that "tent" homes for termites will often put a few of these inside. Burglars targeting the unoccupied house are met with 105db of attention getting noise. Truckers in Sleeper Cabs use them to add a layer of protection for their cargo while sleeping. Others have used them to scare pests out of vegetable gardens, to protect tool sheds, green houses or public storage units.

Review of How this portable motion alarm works:
During product testing we found the simplest mode is to simply install the 9V battery, aim the sensor toward the area you want to protect , put the side selector on the side to CHARM. Give it 60 seconds to calibrate - don't have anyone in the sensors field of view.
Once calibrated, motion (heat) in the field of vision (32 feet out about 110 degrees wide) - will trigger a dual chime which sounds much like a digital doorbell - " DING-DONG...... DING-DONG ". Inside our tent. we found that chime mode is loud enough to wake us from sleep, no need for the full alarm mode.
For alarm mode - slide the CHARM selector to off and enter a code (default is 3 Zero's - 000 - but you can change it) and press the ARM button. It will beep then begin a 60 second calibration - no one should move in the covered area until the second beep sounds at 60 seconds. Now it is calibrated.
Upon motion sense, a 105 dB (105db is about the same sound pressure as an operating gas lawn mower or running chain saw) piercing warbling sound starts. The alarm will continue for 30 seconds, and rest for 30 seconds. If motion continues it will sound for another 30 seconds, then rest. Entering the code 000 and pressing DISARM will exit the Alarm mode. You can program this behavior to longer intervals using the instruction manual. You can also program a delay, so that you can put in the DISARM code before it alarms.
During our testing review, we found if you walk into the field in front of the sensor, it will alarm as expected. If you then hold very still - it will reset and not sound. Wiggling your fingers - it would not alarm. Moving your arm about 2 inches was enough to set the alarm off. It did not respond to inanimate (ambient temperature) objects being thrown into the field. We threw objects like a shoe, a towel, a rock, a football, a big branch - none of them would trigger the alarm.
The alarm reacts to heat. So a pinecone or leaves dropping into your camp at night typically will not set it off (unless they are burning in which case you have bigger problems). Do not aim at a campfire as it will set off the alarm randomly and continuously. Cold blooded animals such as snakes or lizards typically do not set it off. Larger animals (deer, bear, etc.) as well as warm blooded small animals like a cat, raccoon, medium sized birds, or similar definitely sets it off. We have not been in a situation to test whether a small bird, squirrel, mouse or rat triggers the alert. We anticipate more field testing and will update.
Wind can complicate matters if warm and cold air are swirling or there are bushes moving - you can get some false alarms. These are can reduced and nearly eliminated by putting an inverted zip lock bag over the alarm.
During range testing we did get the 110 degree field of detection, maybe even a little wider. On an indoor test in the warehouse we could get alerts to sound for an 185lb. adult male at 45 feet - farther than the claimed 32 foot range. We attempted to make the alarm "waterproof" by putting it in a clear zip loc bag on a picnic table. It worked through the dry bag but cut range to about 25 feet for alerts. Sound of the alerts was not appreciably reduced by the bag. Next, we wet the bag by spraying it with water, so that droplets covered the bag That cut the range to about 20 feet and it seemed to take MORE motion to set it off, but it still worked. We did not test in an actual rainstorm but expect that would cut the range further since the cold rain would tend to block the heat signatures.
One tester suggested that you could setup a "force field" perimeter around camp using 4 alarms - each facing out from the edge of camp - North, South, East, West - about 3 feet off the ground. They could be programed to alarm (105db) and reset after 30 seconds. It might prove an adequate deterrent, like an invisible electronic fence - to scare the bears and critters away, and after they reset - you could go back to sleep.
If you deploy a perimeter - use the delay feature. That will permit you to enter the alarm field and disarm it before it sounds - programmable to 0, 8 or 15 seconds. The delay feature also "draws the unsuspecting target in closer" - so when the alarm does sound they get the full 105 db effect !
Using the screw holes in the back of the unit - it would be easy to fashion a "tree mount" with Speedy Straps or similar velcro straps to properly position and aim the unit.
* This device is NOT RAINPROOF - be sure to install it under your vestibule or rainfly, or cover with clear plastic zip lock bag if rain is expected.
* In order to install a 9V battery, you will need the very tiny Phillips screwdrivers found in "eyeglass repair kits”.
* 105 db is very loud and can damage hearing. Only use Chime Mode if you are using this inside your tent.
