Before buying a storage device USB Network Adapter, these three precautions

ICS Computer storage of office and home networks has proven to be effective to avoid unnecessary duplication of files, video, mp3 to reduce access to multiple computers and laptops. Using a central repository of storage, the files will be entered once and streamed from there, or need, at any time and from anywhere on the internal network, copy, even on the Internet. A convenient way to share files, printers, home network through the useMulti-Port USB or Universal Serial Bus, Luggage network card.

USB adapter or network storage enclosure is a simple serial bus hub, which on the one hand, several ports for hard drives, printers and possibly other USB devices, and on the other side of a TCP / IP is the standard Internet connection . You can "share", then the various Universal Serial Bus devices on your home network policy.

Wireless Network Detector

Many network storage enclosure is currently offered byto promise more than one supplier, the easy sharing of USB devices connected through the home network. Before you buy a network adapter Universal Serial Bus storage, make sure you understand what these "network sharing", and all the reserves that come into force. Understanding this before you buy, you will be able to install and use their functions immediately and without delay or frustration.

The three reservations in dealing with the Universal Serial BusNetwork Storage Adapter are: first, USB devices are not to many users at once, second, USB devices are used, even if developed in order to draw power from the bus can not handle too much power, and thirdly, the unit reformat your hard drive before it can be used within the network storage adapter.

Caveat 1: Only one user at a time from a USB device

USB devices such as printers, hard drives, cameras, neverdesigned to be used by multiple users at the same time. Unlike a normal network drive, in some network storage container, the user needs to access a specific device, and the dedicated connection must first be determined before the drive or device can be used. What makes a further step in the process, and for some purposes, the Universal Serial Bus "shared" device really useless. Not all USB storage enclosure network have this requirement. To checkfirst.

Caveat 2: Connected Universal Serial Bus devices can not be too much power

Many devices require power from the Universal Serial Bus USB port itself. Hard drives, especially a lot of energy. So, especially if multiple hard drives to get a USB network storage enclosure, both hard drives with its own power supply from the network, or ensure that their power to the bus terminal are manageableand is small enough.

Caveat 3: need to reformat the hard drive to be used in a USB network storage enclosure

This can be a nasty surprise when you take the external hard drive that you are using Windows, install it in a cabinet network, follow the instructions (so slowly we suggest the data may be lost), and find all the data on your hard drive disappear. Similarly, because the formatting of hard disk drives that use thesecompatible with Microsoft Windows, remove the disc from its case and the insertion into the socket on your computer or netbook not receive your information.

Troubleshooting network problems Wireless

With the emergence of wireless Internet connections, there are people with good connections to the Internet. Workplaces, restaurants, schools and department stores offer free Wi-Fi access to people, and, above all, these people also prefer wireless connectivity in their homes, enjoy the comfort that connect to the internet via their desktops, laptops or even their high-end mobile phones anytime, anywhere.

Every good thing has a downside andWireless is no exception to this rule. Wireless network problems are sometimes experienced by users. Surely the inability to access the Internet to counter a person, especially if you are in a situation where urgency is at a higher level.

Wireless Network Detector

Here are the most common wireless network problems and some suggestions that may be useful when considering these types of problems:

• No links found

IfIt is likely that you have this case, make sure the wireless switch is turned off the device "on." If it is already on and you have not found any connections, check your position (if it is covered by a wireless network).

• Connections Suddenly Out

What is more annoying than in the middle of sending an important e-mail to your boss off? The signal is suddenly want to throw your wireless router to feel. Whenparticular wireless network problems like this, try to cool the calm and control your cable modem or DSL. Normally in this situation, the problem is not with the router, but it's the ISP that went down. In this case, contact your service provider.

Another possible cause is a conflict of IP address. In this case, try rebooting your wireless router to get a new IP address.

• Loose connections

There are two possibleReasons for this wireless network. The first is that your position or place, or too far from the router in an area where one with too much interference, like cordless phones and cell phones are. Solve this problem by simply moving closer to the wireless router. Another reason is that you can have too many people attacked, or the network to download large files too. Solve this problem by limiting the number of usersable to connect to the network and enable security.

There are just some of the most common problems of the radio network that may be encountered and their solutions.

Wireless Networking

With a wireless modem at home, it has advantages. E-mail, games, PSP, Mobile OS applications, surf the web from your couch or bed, everything has its advantages. The sad part of this technology is almost 30% of users to get the incorrect installation or leaving dangerous free wireless broadband for the rest of us. As I write this article, there are currently 3 users that use wireless networks insecure around me.

This articleteach the fundamentals of ensuring your wireless broadband at home. With a cordless phone, mobile phones and wireless-enabled applications to operate on the principle that the cables of a smaller number of better networking experience. Wireless are easy to use large, but they can if they are not easily affect the security settings Correct or software running in the background. By default, most wireless networks are safe out of the box. You mustRead the manual to find out the different settings are necessary to protect wireless networks. The list that follows are the basics to keep one from entering your network borders.

Wireless Network Detector

Step 1: E 'need to know the current configuration of the network

Wireless technology transmits data over radio waves from one application to another. The signal carrying the data is transmitted over a great distance in kilometers times. Without basic security measuressomeone with the right tools to achieve and to encrypt the data to steal and hack. Insecure WLAN is the most common form of intrusion on private networks.

Step 2: Change your SSID and passwords

SSID stands for Service Set identification number. Each wireless network, from large systems configurations simple home business, contains an SSID. SSID is the name of your digital networks. First, change the number of SSID and default passwordSetting to something private and strong. Never keep the default SSID active. To change the SSID and password, network, launch the software for the wireless hardware. You should be able to change the SSID within the program via the control panel. Overwriting the default SSID will not do you much good if the network name is broadcast to all users in your area. Confidential information can be changed for all users in your area by disabling SSID broadcast. It 's likesimply ticking a box from the control panel of the modem.

Step 3: Set up MAC filtering

Media Access Control or MAC -. A 12-digit network address of the Pocket PC PSP, laptops, desktops, etc. all have a MAC address. It can be difficult to find a MAC address, depending on your hardware. But time's up this section of hacker walk directly to the network and steal information to prevent. For users of Windows desktop, click Start,then click Run, type cmd in the text box. The ipconfig / all in DOS window. Physical address 12-digit MAC address. In practice, the devices to access the MAC filtering on your wireless modem. By identifying that access a wireless modem adds another level of security to the network. For MAC filtering, you open your software and plug the wireless modem ' MAC address of the hardware that you grant access. Usually found under Security Settings of yourModem Control Panel.

Step 4: Encrypt the data and Scramble

Two common encryption protocols WEP (Wired Equivalent Privacy) and WPA (Wi-Fi Protected Access). Both protocols to encrypt data and to block unwanted visitors from entering your network. EPA is seen as more secure than WEP because of the changing fundamental step will be considered. But the EPA is not aware of all devices and is subject to existing hardware and devices. WPA is generally builtIn most router with WEP encryption. It 'very important to ensure that the device supports WPA encryption for the connection. If you are not using WEP and MAC filtering, the determination of most attacks from hackers.

Step 5: Education and software

Stay informed - Learn more about wireless security to keep some 'great articles online before the Internet security .. To check for updates each month, the wireless modem. Keep your table up-to-date with the latest updates fromMicrosoft or Linux. Download third party software such as Zone Alarm to detect intruders and monitor the wireless transmissions at any time. More third-party software decisions soon be added to an article on wardriving.

7 Tips for Easy and fast creation of a secure network home!

Do you have a secure network at home with the use of WI-FI?

In other words, access to the wireless network to the Internet without worrying about hackers, viruses and theft of wireless signal cares? With a home network safe requires more effort and education than just buying a wireless router (s), it connects to the Internet and access to surf while praying no one will hack! What many users do not realizeWhen you configure a home network is that if you buy a router and setup password, by default, the network is not secure.

Wireless Network Detector

If you use Internet service providers (Verizon, AT & T, etc.) will send a broadband modem to other computers on the Internet, wireless (Wi-Fi) allows, it is likely that you're not sure, unless someone on the Internet and Modem installed security configuration "property."

In the new "social networking" age, it is importantAware of the Internet threats that lurk, and how to protect your personal information and data from a home network safe from thieves. Did you know that there are tools and software that exists that allows a person to your home wireless network for steal a connection with him, "crack" the key (password) and what they want from your computer (including credit card numbers, financial, passwords, images and other sensitive dataetc.)!

Let's look at how to create a secure network at home and feel safe - "safe" surfing the Internet.

1). In your broadband (wireless) modem or wireless router, the default name and password for the admin panel of the router (used to modify all settings of the router / modem) access.

Note: The default name is usually "admin" and password is specified in the documentation (or disk) by the manufacturerequipment

2) Always use encryption (password / key), to truly secure a home network.

WEP (Wireless Encryption Protocol) and WPA (Wi-Fi Protected Access), are the two most common types, with the EPA to "crack" more difficult than WEP, WPA, then a better choice for safety.

In addition, it is always better to have a completely new and different password (key), at least every 30 days, to safeguard and protect your home network. Passwordshould be to "guess" difficult - in other words, with a mixture of symbols, alpha / numeric characters, uppercase and lowercase letters and at least 8-14characters if at all possible.

Note: An example of a strong password is: "1mypasswordx90544z" or how about: these are harder to guess passwords using password-cracking software "Tektime1 p0rt $%%".. (Do not "easy to remember" passwords, such as passwords that include your name, the name of your children (s), date of birth, your way will be made;etc.)

3). Turn on your wireless router or DSL modem, if you do not have access to the network.

For example, if you go to bed or if you are not home it is best to disable your Internet continues to act as a protective barrier for your home network secure. As intruders, trojans, etc. cause damage to your computer or Internet connection if not send a signal? You're right ... can not!

4). Disable Service Set Identifier transfer to your modem / router.

Otherwise, as "SSID" is known for the name identifier of the device by the manufacturer. For example, the D-Link router that will "Dlink" as the SSID, while the Netgear router made by "Netgear", as well as the SSID. Turning off the SSID prevents the wireless home network to be in the list of "available networks", if someone seems to scan the area for wirelessTo connect networks>.

5). Change the SSID.

And disabling the SSID of the router, it is important to change the SSID, even if it does not seem due to the last stage where we have disabled. Changing the SSID will not prevent a secure network at home, but that hackers and spies out immediately what your router. You know what router is used, a hacker or thief more willingto cause chaos in the home network, especially if you are accessing the same name, password, and information management standards, such as the manufacturer has created.

6). A network firewall safe at home EVER!

Many firewalls, which can come into your router (hardware firewall) built cause various problems when access to the Internet. It 'best for beginners and novices to use a software solution, to learn the ins and outs of firewall hardware andtheir borders.

Firewalls can be created for the software (eg Trojan horse) to prevent a connection to the Internet without your permission, thus preventing unwanted transfer of data, personal financial information and other confidential information. Firewall prevents access outside your home network without your permission.

Note: A highly reputable software firewall solution, Comodo Internet Security. Feel free to look it up in your favorite search Engine. It's all free (the basic version), to operate very efficiently and easily (after a slight learning curve). I recommend it to all my clients and are not paid by Comodo in order to support them. It 'just a good program, try it!

7). Reduce the scope of the wireless signal.

A secure home network does not transmit a signal to the outside environment of the Internet user at home. So you should reach your> Wi-Fi signal?

Imagine you buy the "biggest and baddest" wireless router that you can be found from a retailer with a range of 1 mile! Wow, this is a long haul ... can be anywhere in the house that does not have a signal loss at all! Although this may be true, the truth is that you only have a signal range of the signal can be transferred into your house, and not necessarily outside.

This prevents thieves connection to the Internet (andHackers) on the possibility of radio waves received by the router or modem, then connect the signal would be virtually impossible, even by more experienced hackers!

Tip: One way to signal your area is less, switch to 802.11 g, 802.11 s, 802.11 or b. Consult the documentation for your router from the manufacturer, contain certain information.

Hopefully these tips will help you to create and sustain a secure network at home, and will not behave nightmares experienced by many people to protect the wireless network is not the face!

Always remember that an ounce of prevention is worth a pound of cure!

Until next time,

Calculation happy!

Intruder Alarm - A Review

Intruder Alarm - A Review

Alarm systems are traditionally equipped premises for many years and are now a growing demand for private homes and gardens as well. If you've ever shopped for a home security system, then you know there are a bewildering variety of options available. These systems range from inexpensive and easy to install alarm systems for sophisticated and complex network security, which must be installed byProfessionals. But as it turns out that most alarm systems actually built around the same basic design concepts, so it is really necessary to spend a lot of money?
Please take a look at the information below and find out some details of the alarm system components. As will be seen, some of the most effective intruder alarm systems, the simplest, easiest to adapt, and less expensive.

Wireless Network Detector

The magnetic switch

The simplest alarm works with a simple circuitembedded in a door or window. In a circuit, current flows only when the path between two points of opposite charge. To connect or disconnect the electricity to open or close a part of the circuit.

The activation of an alarm system if you turn the switch opens or closes the circuit, such as opening a door or window recognizes. The most popular form of this alarm system is a closed-loop system.

In a closed circulatory system, the electricCircuit is completed when the door is closed. This means that until the door closed, electricity can flow from one end of the circuit to another. But if someone opens the door, the circuit is open and current can not flow. This triggers an alarm.

The magnetic sensor as standard in most circuits consists of a simple switching device consisting of a battery powering a circuit, a spring-driven metal switch built into a door frame and a magnet in the door, which is alignedwith the switch.

While the door in the closed position, the magnet attracts the metal switch closed and the circuit is complete. When the door open magnetic spring switch in the open position, cutting the current that triggers the alarm.

You can also adjust this option in a window frame. If an intruder opens the window, the system in exactly the same way the door is operated.

The best alarm systems include a control boxto prevent the intruder the door or window, then reconnect the circuit and disable the alarm. The unit has its own power supply and control circuit and triggers the alarm when the switch is open, but can be turned off when someone in a security code on the keyboard box.

The PIR motion detector

The alarm circuit magnetic circuit described above is ideal for protecting doors and windows of a house,but not always sufficient all-round protection. The best protection for additional motion detectors, which are often referred to as PIR is in good shape.

Passive infrared (PIR) motion detectors are used in most modern and even in some of the basic security settings. These sensors monitor the heat of the body and if an intruder comes into view of the PIR, recognizes the increasing heat of the body and triggers an alarm should be activated.

PIR motion detectors are set tothat the box does not alarm them instantly recognizable beat, the body heat. There is a delay of several seconds that the time to get into home ownership and key in the security code to unlock the system.

One might ask if you can see the movement if you look out through a window. It is not possible, because the glass is not transparent to infrared energy.

Alarm activated

Depending on the type of alarm system installed there may be moreDeterrent to an intruder. In advanced systems, the check box to be connected to various components and is usually to activate a sound alarm siren or loud external siren and a flashing light and a telephone auto-dialers. The siren and lights alert the landlord or neighbors that someone broke into the house and the sound often lead the attacker to flee in haste. The telephone auto-dialers can use a pre-recorded message with the address of the house and canby phone or office phone, a neighbor or someone else who can help.

Wired or wireless?

This is as easy as it seems, means wired burglar alarm systems that connects all the components must be connected together to complete the circuit. However, there is so much easier to install, wireless systems automatically transmit signals between all components of the alarm system to avoid time-consuming and sometimesunpleasant process wiring.

No telephone line or electricity?

GSM burglar alarm systems are affordable vacation homes, boats, caravans or any protection, which connected the phone line and can not work without electricity. These systems are easy to assemble, and similar components to other systems, including sirens to scare off intruders, but also a built-in SIM card and battery automatic dialing you fromWireless network when enabled.

What is the best burglar alarm system?

Basic components are similar in most alarm systems, if they are complicated and expensive alarm systems or simple and easy to install alarm systems. The options and possibilities are vast, but often the choice for a wireless system for a house to protect the office, store room / garage, garden ornaments, holiday home, caravan / car / boat. Wireless alarm systems can be veryEconomic to purchase and are always much easier to install and above all have the same basic components as the most advanced and expensive systems built.

CCTV wireless Internet - Adding PIR

The new generation of CCTV cameras and wireless CCTV cameras or IP cameras is known fully digital, more like a computer in a traditional camera. This new type of camera detects changes in the digital image sensor that "sees" to decide if something is moving in the picture. This method of motion detection can be improved with the addition of a passive infrared (PIR) sensor of the camera, as explained in this article.

There is a limitInternet CCTV cameras to detect motion. These cameras to determine whether there is motion in its field of view, studying the changes in the digital camera that produces images of the optical sensor has occurred. One problem with this approach is that changes in the digital image can come from something other than a person to have been caused. For example, if a lamp post suddenly on the outside of a room in which the camera will be a big change in the digitalImage, it suddenly becomes brighter. The camera will notice this change and a movement to increase detection alarm - a false alarm in this case. There are several ways to solve this problem, such as asking for image processing software in the camera or on a central computer so that people are "recognized" as a person and an image at the level of intensity variation of light is ignored. A simpler solution is to use a PIR sensor.

Wireless Network Detector

A high-quality wirelessCCTV Camera Internet is usually a small connector block port I / O or input / output, as the purpose is unknown. In the port is only a number of holes where they are attached and narrow wires with a screw. The pair of terminals as the input jacks are known to be used if you want to connect a sensor as a motion detector. The inputs are used because the sensor provides a signal to the camera as the camera is in contrast to a signaloutwards.

You need a PIR sensor that selects the camera. The door camera can accept input signals of a certain voltage and voltage, and attaching all the entrance doors, which sends electrical signals above the acceptable range may damage the camera. Fortunately, most of the PIR sensors have a fairly standard power and the cameras are designed with most of them work. Choose a good quality sensor, which can be set forAnd eliminate sensitivity to the movement of small objects, such as pets. For the assembly is easier as you go with a built-in battery. Although in theory to power the camera sensor is possible, in practice it is difficult to obtain sufficient power and the sensor often easier to go for the battery option. Next, we will explore how to find the sensor mounted on the camera.

See your camera's manual to find the pair of jacks to connectblock. Then you simply take the two wires from the sensor and connect it to the inputs of the camera, making sure to connect the positive and negative wires to the appropriate connectors in accordance with the manual, it is more difficult than wiring a plug. Then place the sensor on the wall or ceiling so it's "look" the same view as the camera. This means that if the motion sensor detected, the camera is recording the movement. We must alsoto make a small change in the camera, as in the next section.

The CCTV camera Internet itself must be configured to increase the alarm and disk images will not work if the camera detects motion in itself, but when its input receives a signal from the PIR sensor. There is usually a case of change a single setting of the camera set-up page so that every movement recognition "triggers" is ignored, but it will be an input signal thatcauses the camera to raise an alert. This is usually a simple change but will vary according to the camera model, so please consult the manual for details.

By using a standard PIR sensor with your wireless internet CCTV camera in this way, your camera will be able to detect movement more accurately and consequently the number of false alarms will be greatly reduced.
