Most Popular Home Security Alarms
Modern technology has allowed for many innovations in the development of security alarm systems. And yet, as the alarms become more advanced, so do the methods of burglars. It has come to the point that a simple lock or a crude alarm system is not enough to dissuade an intruder.
For this reason, a sophisticated alarm system is a good investment. Not only does it safeguard your property, but something more priceless- the security of you and your family. Below is a list of reliable home alarm devices:
-Wireless Security Devices- These are battery-operated security devices. The advantage? They are much cheaper. The disadvantage? The system has to be subjected to constant monitoring and recharging.
-Conventional Burglar Alarm- Its mechanism is to make a lot of noise once a burglar is detected. Unfortunately, there are some who know who to disarm it.
-Security Camera System- Security cameras have to be installed outdoors in order to detect the burglar instantly upon entry, however it also makes it prone to being damaged by the elements. Fortunately, there are many modern innovations on this type of security system. Some come with their own blowers and heaters that allow it to operate in spite of climate change. Some are even wireless, making them less easy to detect and more convenient.
-Motion-Detecting Device- These devices can be installed on a window or door. Some are even connected to the telephone and will instantly dial an emergency number upon detection. There are various mechanisms for this device- including infrared, which picks up on body heat, and laser, which transmits a signal once its light source is blocked. To avoid setting off these alarms yourself, activate them when you have to leave the house.
-Advanced Locks- These are not just locks, which burglars can easily break through, but also alarms. Its secret? There is a magnet on the sensor that can detect if a burglar is moving a window or door, and it triggers the sound.
-Glass Sensor- This device is sensitive to the frequency and vibration that glass makes when breaking. Because of this, it is most appropriately installed on a window with a glass pane.
-Perimeter Alarm Devices- These are situated all over the possible points of entry of the house to cover all the intruder’s options. Highly sensitive, it will go off even before the thief manages to enter the house.
-Environmental Change Detector- Not only does this fascinating device provide security against an intruder, it also alerts the home owners to environmental threats or changes.

Home Security Alarm Battery Questions
Home security alarm system
What is Home Security Alarm System? Apparently, it is an alarm system installed at home for the sake of security. It is designed to detect intrusion.
An ideal security alarm system consists of a combination of devices for exterior (or perimeter) and interior protection. Let's look into what the perimeter protection and interior protection are.
Perimeter Protection Generally consists of sensing mechanisms attached to doors and windows leading into the property. These devices are connected in such a way that they will sound the alarm if an entry is attempted and will send an emergency call for help to an authorized person or central monitoring center.
The most widely used device for this protection is magnetic contact (i.e. a switch and a magnet), which works with a switching mechanism. The switch is placed on the frame of a door or window, and a magnet is placed on the door or window adjacent to the switch. When the door or window is opened, the magnet moves away from the switch and the alarm will be activated. In the event that an intruder attempts to bypass the magnetic contacts by breaking the glass at the door or window, device like shock sensor can sense a shock at the monitoring object and send out RF alarming signals to the main unit.
Interior Protection Interior Protection system plays an important role to detect if an intruder has eluded the perimeter security system.
The most common device used for interior protection is motion detector, which can detect body heat or movement of an intruder and activate the alarm. There are three basis types, infrared, microwave, and ultrasonic.
Smoke detector, as an indicator of fire, is another essential device for interior protection. Smoke detectors can sense the presence of smoke particles in the air. They should be located in all levels of the property.
There are many other security devices, such as IP camera and panic button, which can make the alarm system protection more complete.
Installing a home security alarm system in your property can help reducing your homeowner's insurance premiums, but most importantly, a good home security alarm system can protect your family and prevent your property from being robbed or intruded.
How to Build an Alarm Circuit
Building an alarm circuit is one of the easiest circuits to make. There are two type types of alarm circuits: a closed-circuit system and an open-circuit system. Here are the steps to construct a closed-circuit system alarm.
Instructions
Things You'll Need:
Battery
Clip
Buzzer
3 pieces 5-inch wire
1
Prepare your wires. For the circuit to have clean contacts, you'll need to peel off the wire insulation at the end of the wires. Peel off ½ inch of insulation for the wire ends that will attach to the battery. Peel off 1 inch of insulation for the wire ends that will attach to the clip.
2
Connect the buzzer to the switch. In a closed-circuit system, the only time the alarm will not ring is when the circuit is broken. This means that whenever the electric current is moving along a continuous route, the alarm will sound. Start out by attaching one piece of wire to one of the buzzer terminals. Attach the other end of the wire to one prong of the clip by wrapping the wire around the prong tip.
3
Connect the switch to the battery. Take a second piece of wire and wrap the end around the second prong on the clip. Make sure the wires are touching when the clip is closed. This is the part of the circuit that opens and closes. Connect the other end of this wire to one of the battery terminals.
4
Connect the battery to the buzzer. At this point, you might want to stick a thin piece of plastic, or cardboard inside the clip to keep the wires from touching. Otherwise, the buzzer will keep ringing once the battery is connected to it. Take the third piece of wire and connect an end to the other battery terminal. Connect the other end of this wire to the remaining terminal on the switch.
5
Your circuit is complete. Pull the cardboard piece out of the clip, and the buzzer should go off. If the buzzer doesn't go off, check your battery terminal and buzzer terminal connections. Also make sure the clip wires are touching when the clip is completely closed.
Tips & Warnings
Make sure your battery source is strong enough to power the buzzer, but not so strong that it burns the buzzer out.
Use a plastic clip or a metal clip with plastic ends to avoid getting shocked by the current.
