Yes any thin insulated wire can be used which doesn't restrict closing of the cell phone. If you enter the house, all you need to do is cut the call that the security system will dial to your cell phone. We now need to make a mechanism that can be pulled automatically, so as to activate the speed dialing feature of the phone.

The output of U2 timer is used to feed the control voltage of the U3 timer through resistor R6 where it is subjected to frequency modulation. This frequency modulation will generate a tone similar to the police siren. The frequency of this tone generator can be varied by changing the value of potentiometer VR2.

Join the electronics events to enhance your knowledge and network with other professionals in this industry. The output of U2 is used to drive a power transistor which in turn drive an 8 ohm speaker. Diode D2 is used to prevent the damage of transistor Q1 due to the back emf generated by the speaker during the ON/OFF driving of the speaker. U1 is then feed into pin 4 RESET of both U2 and U3 timers causing both timers to start their astable mode operations.
But you don’t have to sit and worry about it happening. With this Instructables project, you can build a simple yet effective alarm system that instantly goes off whenever an intruder tries to access your basement. If you follow this Instructables guide, you can build something close to that as part of your security system. It may not feature a laser maze with sophisticated man-sized holes, but it’s invisible and will instantly trip and set off the alarm whenever an intruder attempts to pass it. Hook it up to an existing security system, for instance, floodlights, or any loud external device, to enhance its efficiency. Build this simple home alarm to protect your house from intruders.

If all the above Step 3, 4 and 5 are correct, disconnect the power supply and insert IC1, IC2, IC3 and IC4 in to the appropriate IC bases. Attach suitable speaker to the X4 and connect RS232 cable to the system. This alarm alerts you whenever anyone tries to sneak into your room.

Look for ones that double as floodlights, like the Ring Spotlight Cam. One way to help ward off burglars is to shine a light on them. Break out the toolbox and install a floodlight camera or motion-activated lights to illuminate dark areas around your home. Consider installing an electric keypad deadbolt that offers the option of entering a code rather than using a key to unlock the door. Nearly 1.6 million burglaries occur every year in the US—that’s one burglary every 20 seconds.
IoT Security System Project Description:
This control system consist with the menu driven configuration options, self tests, system report generators, etc. This system also contain 5W (with 4Ω speaker) audio alarm with three selectable tone configurations, which include Police siren, Fire engine siren and Ambulance siren. Do you want to up your home’s security but can’t afford the high price tag on CCTV cameras? This security camera lamp build on Instructables is just what you need to scare off intruders and light up your home’s space. You can opt to purchase a dummy camera or DIY your own using old cans to hack this project. The process of making a mouse security alarm is pretty straightforward, as shown in this Instructables guide.
Put up smart window treatments like Yoolax and use a home automation system to control them from your connected device. In addition to keeping prying eyes from seeing inside your home, smart window treatments may help reduce your home’s energy consumption. It won’t take you long to accomplish this security project, but it could help thwart a burglary. If you’re like most homeowners, you’ve “hidden” a house key somewhere outside your home, like under the door mat or in the shed. Burglars know where to look, and if they find your house key they won’t think twice about using it.
Upon scanning the right tag and entering right pass, it will open door and send confirmation message otherwise it will send alert message.

Make sure that all the keys work well except the key on which the wires are soldered. Remove the conductive plate from the button sticker of the corresponding key. Permanently turn Off the Keypad lock on the cell phone. In this project, we will be using the power of RFID to tap into your garage door opening system. Why use a relay module when plain relays are cheaper? We will show you how to control your lights with an Arduino.
This could be the simplest YET brilliant project / idea. The plastic will retain its shape when cooled down. Carefully peel off the button sticker from the keypad.

Feel free to implement the projects above as they are or customize them to suit your own purposes. This is a great idea and reminds me how I used to hack computer keyboards create custom buttons to interact with programs. I'd do something similar with soldering buttons and switches to different parts of the keyboard control board.
This idea could be added to any other alarm system. An alarm trigger from any other sensor could be use to initiate a phone call. This project only works with a working cell phone that is also active to make calls. Solder the wires to both the terminals of a key to which a speed dial was assigned. After verifying all the settings, turn the device Off. Our project is about Security because security is one of the concerns today.

The first timer U1 is configured as a monostable timer with a variable timing of up to a maximum of 220 seconds. The timing can be changed by adjusting the VR1 1M ohm potentiometer. If you need to further increase the timing, the electrolytic capacitor E1 can be changed to a larger value. Once the contact CT is momentarily closed, a pulse will be generated at the output pin 3 of U1. I created an alarm clock using a motion detection sensor so that you're not able to just hit the snooze button and go back to sleep. This alarm clock and timer work without the help of a computer.
IOT Security System Program Explanation:
The alarm gets triggered and beeps continuously till the time the circuit is reset. The middle one is the OUT “Yellow Wire” while the rightmost pin is the ground “Black Wire”. I have a very detailed getting started tutorial on the PIR sensor. So for the basic understanding, you should watch that tutorial which explains everything. You can find a link to the tutorial in the related projects section. Would i be able to use this for a class project at school.

Remember that CRT monitor that’s gathering dust in your attic? Just because it’s years behind technology doesn’t make it completely useless. Check out this guide on Instructables to transform a CRT monitor into a personal electric fence. Here are more creative ideas to upcycle old TVs. You don't have to spend a fortune to keep your home secure. Check out these easy-to-make DIY home security projects.
