Home alarm is a final degree project that develops a complete wired alarm system for a home or shop.
The project focuses on software development. However, there is a few information about electrical and electronic components.
In this folder is located the source code for an Arduino MEGA 2560 board.
In this folder is located the source code for a server who must to be installed on a GNU/Linux 24/7 machine.
For the prototype I have used a Raspberry Pi 3 board and it worked great. There is something that worries me and should be valued: I mean that the Raspberry Pi works with a micro SD card and there is a limitation of amount of read and write cycles, therefore, an alternative such as using a RamDisk should be sought.
The directory structure used by the server software is as follows:
/
└── usr
└── local
└── bin
└── servidoralarma
├── config.json
├── ServidorAlarma.jar
├── cam
│ ├── cam_1
│ ├── cam_2
│ ├── ...
│ └── cam_n
├── lib
│ ├── jSerialComm-2.9.1.jar
│ └── mysql-connector-java-8.0.28.jar
└── sql
├── insert.sql
└── script.sql
servidoralarma and ServidorAlarma.jar names can be modified by another language (they are in Spanish) but if they are modified, these changes must be transferred to the service script. Don't mind, it's quite easy. Take a look at the project document.
config.json is a plain text file with JSON format that contains the configuration payload for the server. This file should be configurated once per installation. This file is quite important and it must to be placed with the server .jar file. Its content is as follows:
{
"server":{
"rmi_port":28803,
"serial_port":"/dev/ttyACM0",
"prearm_code":"159"
},
"firebase":{
"firebase_token":"[firebase_token]",
"url_fcm":"https://fcm.googleapis.com/fcm/send",
"android_channel":"alarma_vivienda",
"uri_image":"[uri_to_image]",
"time_to_live":2419200
},
"sql":{
"url":"jdbc:mysql://localhost:3306/",
"user_name":"[user_name]",
"user_password":"[user_password]",
"script_create":"sql/script.sql",
"script_insert":"sql/insert.sql"
}
}config.json file contains critical information so it must to be owned by root user with 600 permissions' mask.
In this folder is located the source code for an Andoid mobile smartphone. It is currently bilingual: English and Spanish, but you can easily implement other languages from the Android IDE.
You will need to download the google-services.json file from Firebase. (see https://firebase.google.com/docs/android/setup)
In this section I am proposing a BOM (bill of materials) with the intention of generating a final product based on the prototype. For example, the alarm client and SQL database can be hosted on any hardware on the home network, and I use a Raspberry Pi for this. You can use a NAS, for example, if you already have one.
Alarm switchboard
- Arduino MEGA 2560 Rev 3
- Proto-board
- PNP transistor (2n2222 or similar)
- 1KOhm resistor
Server
- Raspberry Pi 3 B+
- SD card (example: 128GB Class10 U3 V30)
Others
- Wiegand entry controller with numeric keyboard and RFID reader (example: KR602-M)
- Movement sensors (example: Pyronix KX10DTP)
- Opening door and window sensors (example: MC-38)
- IP camera(s) ONVIF and/or RTSP compatible
- Siren (example: AS210N)
- USB cable (USB-A to USB-B)
- 6 wires cable (0,18 mm2)
- Power supply 12VDC with UPS function (example: DRC-60A)
- 12V battery (example: 12V 4.2Ah)
- Safety box (example: PAR-116)
Pay attention to the dimensioning of the power supply, the current consumption of the motion sensors, the siren when it is sounding and the battery capacity.
