Trip Wire Alarm | Cove Security (2022)

Trip Wire Alarm | Cove Security (1)

I remember as a kid, my little brother used to love playing tricks on me. One of his favorite shenanigans was to hide in a corner quietly and wait for me, the unassuming sister, to cross his path. When I did, he'd jump out and lay down in front of me quickly, causing me to tumble to the ground and start crying. He called his little game, "Tripper". Needless to say, I hated it.

So what does this little anecdote have to do with a trip wire alarm system? Honestly, more than you'd think. My brother had figured out a system (albeit using his body rather than a real wire) that has been around for over a hundred years now. He was using his body to topple me over, thus incapacitating me and making it difficult for me to get up right after I fell. All he was missing was an alarm. Although he probably didn’t want an alarm, or he would have gotten in trouble with mom.

You are probably familiar with the term “trip wire.” These simple mechanisms have been used in wartime, in hunting traps, and in security systems. The basic idea is to have something, usually, a wire (although, as you will see later, lasers can be used as well) stretched out across a path or doorway, Trip wires are attached to two fixed points, such as fence posts or trees. The tripwire should be firmly fixed in place, so that it is taut enough to trigger when a person or animal trips over it, or causes it to move at all.

The earliest trip wire systems were attached to bells instead of a modern alarm. When the wire triggered, it would pull on the bell, causing it to ring and notifying anyone nearby that intruders were in the area. These systems were also used to set off bombs when enemies encroached on home territory during WWI. Enemies approached, activated the tripwire and caused the firing pin to lose tension and go off. Despite the incredible damage these bombs did, the system was undeniably elegant. This system was also used to trigger an attack alarm, notifying soldiers to be ready to fight.

Trip wire alarms today

Today, trip wire alarms are much more technologically advanced. Many systems incorporate laser technology that will sound an alarm if someone were to step across the laser. That’s right, you read that correctly. Lasers. Not exactly like the rotating lasers in Get Smart or the James Bond films, because these laser systems are invisible. No glowy red lines crisscrossing all over your yard and house, just simple, understated, invisible technology.

This kind of technology has a couple of advantages:

While burglars or intruders may be a little bit less likely to run away if they can’t see the tripwire, police can be notified without their knowledge, making it easier for police to catch potential trespassers or intruders.

Invisible lasers, unlike wires, are much harder to find and disable than a more archaic trip wire alarm system

Let’s be honest, it’s pretty cool that laser technology is becoming a relevant part of home security. Technological upgrades like this mean that these kinds of alarm can be wireless and much more aesthetically pleasing.

So how do laser trip wire alarms work, exactly?

Well, there are a few different components. Obviously, there are your lasers. These are created using a laser diode (a mechanism by which laser beams are produced) reflected against a light sensor. These are hooked up to a circuit board of some kind, which then talks to a computer that has been coded to do an action (whether that is to sound a buzzer, to call the police, to lock the doors, or all three). When the beam of the laser is broken, a switch will flip on the circuit board, which will then trigger the computerized response, notifying you of any intruders in the area.

Who is this technology for?

There are many uses for tripwire alarms. Most often, you’d think of them in relation to home security. A tripwire system can make for a great perimeter alarm around your home.

There are also some fairly easy do-it-yourself alarm systems that you can put up just about anywhere. YouTube is full of DIY project tutorials on how to make simple tripwire systems out of a laser pointer. These simpler systems will require a battery to power them unless you want to plug them in. They are created by setting up the laser pointer and reflecting it against a light sensor. This sensor is hooked up to a circuit board of some kind, which then tells the computer that has been coded to do something (whether that is to sound a buzzer or to send you a text message). When the beam of the laser pointer is broken, (the equivalent of someone tripping over a wire) a switch will flip on the circuit board, which will then trigger the computerized response, notifying you of any intruders in the area.

The possibilities for these are endless. If you’re in a college dorm, and you suspect that your roommates are stealing your food, set up a device in the cupboard with your food. You’ll be able to catch them in the act (I fantasized about this as a freshman). Hackaday.com offers an alternative possibility: installing one in your office space so that if someone walks in, you can act distracted. If you’re a hunter, it wouldn’t be too hard to set one of these up as a trap. Below is a video of one way to make a trip wire alarm.

DIY trip wire alarm with fishing line

If you don’t want a tripwire alarm that’s quite as technologically advanced as a laser-run system, or you don’t trust yourself to be able to code a circuit board to do what you need, you can fashion your own tripwire alarm out of some very simple elements, including fishing line, some kind of lever, and a bell or alarm.

The first thing you will need to do to set up your simple tripwire is locate the area in which you hope to set up your system. This should be in an area that you feel is vulnerable, or an area through which, you are worried that an intruder might be able to access your home. You need to have two anchor points. These points could be trees, bushes, lawn light fixtures, or for a much better system, you could use hidden stakes that you drive into the ground. Next you will stretch the fishing line tautly between the two anchor points. On one side, you will need to tie the fishing line around the stake. On the other side you will twist the line around the stake, and you can tie it as well, but be sure not to cut the line, as you will be running the line up to a bell that you anchor in a tree near a window, or on the window ledge itself. Make sure the bell is loud enough that you will be able to hear it from inside your house.

Once you have anchored the bell in place, you will tie the fishing line right above the bulge at the top of the bell. Your system is complete! Before you leave it, though, you should test it out. You will want to apply some pressure to the line. If you hear the bell ring loudly, your system should work great. If the bell only rings faintly, you will need to pull the line more taut. This should ensure that the bell rings loudly. Alternatively, you can attach the line directly to the clapper and see if that produces a louder noise.

This kind of alarm will go off no matter who crosses it, be it animal or human. If possible, you should run the line at knee-level, so many animals will be able to scamper under the line without triggering the alarm.

What are some other cool home security devices?

Laser security systems, while cool, are not the only way that you can protect your property from unwelcome visitors. Other gadgets are available as well. If you're a DIY kind of person, you might want to take a look at some of Cove's DIY home security system products. The idea behind Cove is simple: to enable you to install your own security system, using quality products for a great price.

Some of these products include:

  • Central Control Panel: Cove's central control panel is the brain of the system. From this panel, you can arm and disarm the system, contact security personnel, and often also notify the authorities of any medical emergencies. It's easy to use, easy to install, and (especially great for the current climate) requires no interaction with any door-to-door salesmen. Social distancing, people!
  • Security Cameras: These can be placed in many locations throughout your home, whether that be above your door or in your hallway. These will track who is in your house, and some can be set to run only when you are not at home. Cove's security cameras are especially great because they are backed up to the cloud, rather than to an SD card or similar technology.
  • Motion Detectors: The name is fairly self-explanatory. These track movement and notify you of any human motion on your property. They are actually pretty similar to the laser alarms in this way.
  • Window Sensors: A common point of entry for trespassers and burglars can be a window. Window sensors monitor the movement of the windows in your home. Glass-Break detectors can also be placed on windows to sense when a window has been broken, indicating an attempt at forced entry.
  • Door Sensors: These track the opening and closing motion of doors in your home. This is a key part of preventing burglary, as burglars will often need to go through one or more doors, even if their initial entry is through a window.
  • Key Fobs: These can control the system from a little device on your keys. They are also able to arm and disarm the system and are convenient for when you are outside of your home.

So, as you can tell, there are many ways for you to secure the perimeter of your home and protect your family and valuables. At Cove, we want you to feel as safe as possible. Please take a few minutes to check us out!

Despite a solid foundation, Cove Smart can't distinguish itself in the ever-more-competitive DIY home security market.

Most people shouldn't buy Cove Home Security -- not because it's a bad system, but because it fails to rise above the competition in any clear category.. What's more, there is no self-monitoring option with Cove -- meaning you can't install cameras or sensors and check them on your phone without opting for a monthly subscription that includes professional monitoring.. For instance, I found a place on the app to create "scenes," where a sensor might trigger smart home devices.. First up: the indoor camera, which you need to install with the Cove app.. The installation process for the outdoor camera was pretty much identical.. There's a link on the app screen to help you troubleshoot.. Cove's outdoor camera offers few smarts for its $200 price tag.. Eventually I circumvented the problem by snapping a screenshot of the QR code, blowing it up to about quadruple size on my laptop screen, and scanning it from there.. Cove. SimpliSafe. Hub. $250. $200. Door/Window sensors. $15. $15. Motion sensor. $30. $30. Flood sensor. $20. $20. Glass break sensor. $35. $35. Keyfob. $25. $25. Smoke/Carbon monoxide detector. $55. N/A. Emergency button. $20. $20. Indoor camera. $99. $99. Outdoor camera. $199. $170. Interestingly, the Cove app says the indoor camera can also listen for various sounds, like babies crying or people calling for help -- a fairly high-end feature that would require computer processing either on the device or in the cloud.. David Priest/CNET. While Cove's indoor camera edges out SimpliSafe's with its person detection feature, the opposite is true for the outdoor camera.. Cove's outdoor camera has fewer features even than its indoor camera.. If you're able to find the system, as I did, on a 70%-off discount -- and you're less interested in self-monitoring than professional monitoring -- go for it.

The basic purpose of Alarms and /Trips : Something happens, a signal peaks or falls and you need to know that so an control action can be taken,

Because of the potential consequences to plant and personnel, “hard” alarm trips continue to be the accepted industry standard for a wide range of primary alarming functions, as well as for backup of DCS and PLC strategies in critical Emergency Shutdown (ESD) and Safety Related Systems (SRS).. An alarm trip accepts an input signal from a monitoring or control instrument, such as a signal transmitter or sensor.. Warn of trouble by providing a “hard” alarm output when a process signal exceeds a high and/or low limit.. A status change (alarm condition) of a single high alarm occurs when the input rises above the trip point.. When the input rises above Trip Point 1 (the lower trip point), the first set of contacts will change status merely to serve as a warning; however, should the input rise above Trip Point 2 (the higher trip point), the second set of contacts change status, which may initiate an emergency shutdown.. A status change (alarm condition) of a single low alarm occurs when the input falls below the trip point.. Both contacts on a DPDT change status at the same time.. An alarm trip with a relay that de-energizes if the input signal exceeds the trip point is called failsafe (Figure 16).. This unit’s relay is energized in the normal operating condition.. This unit’s relay is de-energized when the input signal is in the normal condition (Figure 15) and energized when an alarm occurs.. The alarm trip fires its relay at the trip point and the relay resets when the process variable reaches the deadband point.. Some alarm trips can be set with an alarm response time delay that stops the alarm from going into an alarm condition unless the trip point has been exceeded for a specific time period (Figure 18).

Cove recently entered the market as an affordable DIY home security option. We recently tested and reviewed Cove, and we really liked what we found. But today, we’re going to dig into Cove’s equipment costs and monitoring plans to see if they have a system that works in your budget. You’ll see that it stacks up surprisingly well against other affordable home security systems like Abode and SimpliSafe.

If you don’t want to spend a fortune on home security devices, here is how to build a tripwire alarm dirt cheap and crazy simple.

Let’s begin with the basics: what’s a trip wire alarm?. Then, if an intruder walks through and trips over the wire, an alarm is activated.. Keep in mind that what I’ve described above is the most basic type of a tripwire alarm, as it refers to an actual wire and all that.. If you want to protect a far-away location or a room or door inside of a building, you’re going to need a lot of wire, making it pretty difficult to set up.. Classic direct-tripwire alarm, i.e. the line stretched across a path, directly connected to the alarm using a wire/string/cord; Laser/infrared tripwire alarm, which, instead of a wire/cord stretched across the path, uses an invisible laser/infrared beam; Radio frequency tripwire alarm, when the tripwire assembly is connected with the alarm wirelessly via a radio transmitter.. Needless to say, this project is very cheap, fairly easy to DIY and it works awesomely (the BANG part will scare most intruders away in a jiffy).. The basic idea behind this DIY project is that once the intruder trips over the wire, the mouse trap is activated and as it triggers, it detonates a ring cap, making a loud BANG.. Last but not least, this is the uber-high tech laser tripwire alarm , a fairly easy DIY project for your home security that will require a couple of mirrors, a cheap laser-pointing device and 10 dollars’ worth of electronic parts available at any Radio Shack or on Amazon.

There’s nothing more important than keeping your home and family safe from intruders.

How To Install A Tripwire Alarm On Your Property. There’s nothing more important than keeping your home and family safe from intruders.. While you can get a professional surveillance system anytime, they usually cost a fortune to install and may bring a lifetime of monthly fees.. A survey among inmates who were serving time for burglary revealed that some of the most effective burglar deterrents are the cheapest, such as leaving your television or radio on while you’re away and setting up very loud alarm systems.. Most of the respondents to the survey questions said that they would leave immediately once a loud alarm sounded.. A trip wire alarm is a basic security system that has been used during wars, hunting, and camping and now as a burglar deterrent.. The most popular trip wire alarms are radio-frequency trip wire alarm, laser trip wire alarm, and direct trip wire alarm.. The direct trip wire alarm is the cheapest and easiest to set up.. an ultra-loud attack alarm or keychain alarm; several meters of thin wire or fishing line.. Attach the attack alarm to a pole or tree trunk.. Tie the pin to the wire or fishing line and the other end of the line to another tree, as shown in the video.. Set these trip wire alarms across the entrance to your property, in your backyard, in front of your garage, or any place that needs to be secured.. Stretch the wire/fishing line to just a few inches or up to a foot above the ground.Once an intruder trips over the wire, the alarm will go off very loudly and send the burglar scrambling away for fear of being caught.. Spider Hole Tactics to Defend Against Looters

Build your own tripwire security system.

The most inconvenient thing about a classic tripwire alarm is that it requires you to run a physical line from the tripwire to the alarm.. To get around this problem, I designed a simple remote alarm system that uses a small radio transmitter to activate the alarm wirelessly.. I decided to use a wireless doorbell because it was small, battery powered and it is easy to program them so that multiple transmitters can activate one receiver.. Step #2: Add Wires to the Switch on the Transmitter The only modification that you need to make to the transmitter is to solder some extension wires to the button terminals so that it can be activated by an external switch.. Step #3: Create a Switch That Will be Activated By the Tripwire In order to activate the transmitter you need an electrical switch that will react to the tripwire being pulled.. You may also want to drill a small hole in the opposite end of each piece to attach a line when hanging the tripwire.. You can connect the two pieces by putting the free end of the fishing line between the screws on the clothespin.. If the fishing line is too thin to keep the screws separated, then you can add a small piece of plastic onto the end of the line.. When someone crosses the tripwire, it will pull the line out from between the screws of the clothespin switch.. Step #6: Optional: Change How the Receiver Alerts You The receiver will normally play its standard ringtone as the alarm.. (example: (4.5V-3.0V)/0.020A=75ohm resistor) When connecting the LED and resistor to the speaker wires, be sure to match the polarity of the LED.. Step #7: Optional: Setup Multiple Tripwires and Transmitters. If you want each tripwire to set off a different alarm, then you need to make sure that each transmitter and receiver pair is set to a different frequency.. If you want to have multiple tripwires all set off a single master alarm, then you need to make sure that all the transmitter/receiver pairs are all set to the same frequency.
