How to Make a Homemade Driveway Alarm

A home entry alarm is a great way to optimize the security of any home in a simple way. Many different entry alarms are available on the market today. Many users are not willing to pay the costs of any of these units.

For all these people there is a very efficient way to create a homemade and efficient entry alarm. These types of devices are very easy to install and provide great security against any suspicious event.

Here’s the best driveway alarm guide for you to check later.

This type of alarm consists of two main components: a sensor and a receiver. The receiver receives the signal from the sensor that informs the user of any issues. The sensor can detect different movements depending on its design and functionality.

Some sensors have random motion detection. This means that the sensor will detect any type of motion regardless of whether it is animals, vehicles, or people. A break beam sensor or an infrared motion detector sensor can be a great way to be fully aware of what is going on around the home.

Another popular sensor can detect specific motion. Only particular objects or things are detected, such as the metal of a truck or a car. These sensors incorporate a probe or metal detector. The user will be able to count on a heavy metal detector.

The type of entry alarm you want to get, either wired or wireless is very important. A wired entry alarm requires wires to link the receiver and the sensor. A wireless input alarm relies on an antenna to make the connection between these two components.

The problem is that there may be some connection obstacles due to radio interference. 

Creation of the Home Entry Alarm

To get started you need some tools and supplies that people can get very easily and simply. We are talking about creating an alarm that is mainly a wireless motion sensor. All that is needed will be:

  • Drill drill bits
  • Wire strippers
  • Soldering iron
  • Screwdriver
  • Motion sensor
  • 120v Outdoor / exterior white with plug
  • Wireless doorbell
  • Marrette connectors
  • Low voltage wire
  • Solder
  • 120v mechanical relay
  • Waterproof electrical box 

Once the person has all these pieces, he/she can start with the manufacture of this alarm for the entrance of the home. People choose this solution as an effective and economical method to protect the family.

1. First steps

electrical boxPeople will have the possibility to incorporate a different amount of sensors depending on the functionality they want to obtain in this alarm. The most common is to incorporate a motion sensor although other options could also be taken into consideration. One of the best that you should consider is the product at Guardline, but, what is Guardline? It is a manufacturer of a device that specializes in a particular model that works as an outdoor motion sensor. You may check them out!

A certain number of holes are needed in the waterproof electrical box depending on the sensors to be incorporated. Taking into account the size of the outside electrical cable and the sensors, some exact holes must be made for that. This requires the use of a drill of some kind to obtain this result. (1)

2. Incorporate the wireless doorbell

doorbellThis component will serve to let the user know the exact time when a person has been detected by this device. You need to define where the wires and the circuit board that will be responsible for activating the alarm are located. It is necessary to separate the button from the wireless doorbell.

The user needs to determine which connections are to be soldered to the wire. It is best to have a multimeter and test the switch. The soldering can be done properly with a low voltage wire.

By crossing the two wires that were connected it is possible to check the correct operation of the doorbell. This will allow the user to continue assembling the doorbell switch.

3. Mounting procedure

You should make the electrical connections between the outside wires and the motion sensor wires. Both wires must be carefully stripped. Taking into consideration the location of the relay, the doorbell wires must be connected.

Inside the waterproof box, the outdoor cable and the motion sensors should be connected. The power supply wires of the motion sensor and the power supply wires of the outdoor cable should be connected with marette connectors.

You need to connect the common wires of the motion sensor to the common wires of the outdoor cable together with an additional cable intended for the relay. The cable AND the switching cable should be connected next to the relay coil. Once all these connections are made the result can be tested.

4. Installation

5. Additional considerations

The waterproof electrical box must be large enough to incorporate all the elements inside. This is where the doorbell switch, wiring, and relay should be inserted. (2)

The motion sensor must be powerful enough to be able to cover the entire area in which you decided to install this device. The sensitivity and the area that each motion sensor can cover, it’s very important.

Final words

Installing this type of device is a relatively simple task and does not require a large budget. This simple procedure can considerably increase the protection and security of a home. Living much calmer and safer in your own home can be much simpler than you think.
