A Simplified GPS Tracking Overview

The Fundamental Workings of GPS tracking Devices

The GPS tracking device, short for Global Positioning System, is a device that determines the exact position of a person, automobile, or other moveable objects using satellite, cellular (aGPS), or radio waves. In the most fundamental form, a GPS tracker device typically communicates with a network of satellites in low space orbit. From there, the networks of satellites triangulate the tracker's approximate location. This means anyone can place the GPS tracker in a totebag, vehicle, or on a person and find their location..

Depending on the type of GPS tracking device you choose, the locations it goes to are either stored within the tracking device itself to give you a complete documentation of just where the device has been, or with a real-time tracker, the positioning information may be transmitted to a central location or your own Internet-connected computer in real-time, each time the device relocates. At first popular with law enforcement officers, many businesses recently have adopted the technology to streamline operations and now even by families to protect their loved ones.

The Difference Between Real-Time v. Passive GPS Trackers

There are two main types of GPS tracking: real-time and passive.

Real-Time GPS Tracker

Like all tracking deveices, a real-time GPS tracker continually communicates with space satellites to triangulate the tracker's current position. the element that makes the tracking real-time is simply that the unit transmits all data to the Internet database constantly in real-time, allowing you to get on and view the tracker's movements. Most GPS units also give other information such as time, place, and how fast the tracker is going. Originally only used by law enforcement agents tracking criminals, this technology is now common to businesses tracking company vehicles and families tracking new teenage drivers or a family vehicle as it travels.

Passive GPS Tracker

The other key type of GPS tracker is a passive tracker also known as a GPS logger. Like a real-time device, these devices constantly send digital messages to low space satellites, but, instead of transmitting the device's position in real-time, passive GPS deveices save location points within the tracking device itself. When you are ready to see exactly what locations the device has been, you can download a saved data of all places visited. This is ideal for law enforcement during investigation, or perhaps someone who loaned a vehicle to an employee, or family member and wants to verify that the driver really took the car where they said they did.

What To Look For When Buying A Home Door Alarm System?

Simple models of anti-burglar door alarms only offer the core features: switch them on and you’re ready to go. Other more high-end models offer the capacity to modify the settings of the magnetic sensor, include a strobe light or can be operated by a remote control.

Portable Door Alarms

You may even find door alarms that can be hanged over the knob of the door. if an intruder touches the knob a vibration sensor sounds the alarm. Portable door alarms are be very effective for travelers who wish to have greater security in their hotel room.

Types of Door Alarm Systems

There are two kinds of door alarm security you can get. Wireless and hardwired, each one of them with certain pros and cons. Let’s take a look at each:

Wireless Door Alarm Systems

These type of door alarms two main advantages is that they are uncomplicated to put in place and are inexpensive. Their main disadvantage is that they are not controlled from a centralized command center and the battery might run down without you knowing.

Hardwired Door Alarm Systems

The principal advantages of a hardwired door alarm are that the device permits the control of the alarms via a centralized control panel and are less likely to fail than wireless door alarms. Their principal disadvantage is that they can be expensive and harder to install requiring you to make holes walls and floors to string the cables.

Door alarm System should be part of any office or household security solution. They are a cost effective, uncomplicated technology that could end as the final barrier between your loved ones and a burglar.

Put in a Door Alarm Immediately If You Need Safety

Every organization needs security. However in a society of computer passwords, magnetic keys, CCTV cameras, laser beams and security guards what use is a simple door alarm? I mean, if an intruder wanted to get to a special area or get into an off limits room, he would have to go through multiple protection measures. How will door alarm devices deter anyone to do all that?

What Is A Door Alarm?

A door alarm is a simple piece of equipment which is put on the frame of a door. If anybody opens the door the unit will make a high sound, telling you of the entry of an intruder.

Door alarms are commonly used in homes, sometimes as a garage door alarm. Door alarms are often installed at business locations as well. These units are easy to use, discrete and not often objects of attention.

The basic advantage of a door alarm is its price compared to other security equipment. You’ll find door alarms with prices from 10 to 50 dollars based on the maker and the quality of the unit you select. Be sure to make an adequate balance between price and value. If any thing bad happens due to a flawed door alarm, you will be the one blamed for picking it.

How Does A Door Alarm Work?

A door alarm creates a magnetic field. If the magnetic field is broken, the device begins letting off anoisy siren that startles the burglar and warns you of the illegal entry.

Since it doesn’t use a lot of electricity, a GSM door alarm doesn’t need to be connected to the electrical system of the building. It uses a simple battery that lasts, about, 1 year. If you had wireless door alarms installed or wish to install them, you might want to consider using good batteries and executing a maintenance schedule and change them at determined periods of time.

In the case of hard wired door alarms, these units are connected to the electrical system of the building. The more expensive devices have battery back up in the event of a power out.

What Are The Components of Door Alarm Systems?

A door alarm is composed of a receiver and a sensor. The units sensor will be attached to the door frame while the receiver is attached to the actual door. The sensor will be the one emitting a magnetic field. On the other hand, the receiver is in charge of signalling the alarm when the reception of the magnetic field is cut off.
