Why Need a Network Security Camera

Pros

1. Easy to install: Most of the network cameras on the market are plug and play and/or have very simple to follow instructions for both the hardware and software end.
2. Comparatively cheaper than other security systems: Instead of paying a highly trained technician to install a complex CCTV system, and pay him on an ongoing maintenance arrangement- you can have a network camera security system that can stand on it's own against CCTV and traditional security systems.
3. Works with your existing computer network: If you already have a home network, then the network camera works with your settings, so you don't need to pay more for the proper security infrastructure.
4. Provide peace of mind: watch your home, watch your childs room, watch your vacation home, watch your pets while you are on vacation, etc
5. See remote areas: as far away as across the globe, or your own front porch from a centralized area. Can even remotely view your children at the nursery (depending on the nurseries policies though this is becoming more standard)
6. Flexibility: Prefer not to be tethered to the security control panel or hire a full time security professional to monitor things, then get security alerts which you can view from cell phone, laptop, or PDA device, and provide multiple users access to the various security assets.
7. Receive alerts via email when detects motion, either when someone visits your home, or when your children leave home to hang out.

Cons

1. May have poor image quality depending on model and configuration, and wireless cameras in general have poorer image quality on the lower to mid range.
2. For more bells and whistles, like sound recording, scheduled emails, and motion capture, it varies greatly from model and software description.
3. Generally, outdoor surveillance equipment is more costly, especially if you want the ability to remotely pan/tilt, zoom in, zoom out, and want a waterproof camera. However for a home system this is probably not as urgent as opposed to for a business situation.
4. Drains computer network resources, so if you don't have a speedy computer, then there's a chance of a slight slow down in your collective resources.

Remember that despite the cons, the benefits outweigh them as they provide great security results at a lower installation and maintenance cost than traditional Closed Circuit Television systems.

Bluetooth Security

Bluetooth Security

These days, all communications technology faces the
issue of privacy and identity theft, with Bluetooth
being no exception.  Almost everyone knows that email
services and networks require security.  What users
of Bluetooth need to realize is that Bluetooth also
requires security measures as well.

The good news for Bluetooth users is that the
security scares, like most scares, are normally over
dramatized and blown entirely out of proportion.  The
truth being told, these issues are easy to manage,
with various measures already in place to provide
security for Bluetooth technology.

It's true that there has been some Bluetooth phones
that have been hacked into.  Most devices that are
hacked into are normally those that don't have any
type of security at all.

According to Bluetooth specialists, to hack
into a Bluetooth device, the hacker must:
    1.  Force two paired devices to break their
connection.
    2.  Steal the packets that are used to
resend the pin.
    3.  Decode the pin.

Of course, the hacker must also be within range of
the device, and using very expensive developer type
equipment.  Most specialists recommend that you
have a longer pin, with 8 digits being recommended.

Fundamentals of security
The "pairing process" is one of the most basic levels
of security for Bluetooth devices.  Pairing, is
two or more Bluetooth devices that recognize each
other by the profiles they share - often both must enter the same pin.

The core specifications for Bluetooth use an
encryption algorithm, which is completely and entirely
secure.  Once the devices pair with each other,
they to become entirely secure.

Until they have successfully paired, the Bluetooth
devices won't communicate with each other.  Due to
this pairing process and the fact that it is short ranging - Bluetooth technology is considered to be
secure.

As the news has indicated, experienced hackers
have developed ways to get around this level of
basic security.  There are ways to get around this
threat, as you can install software to prevent
hackers from getting in.

With Bluetooth becoming more and more popular, it's
really no wonder that security is always in
question.  As Bluetooth gets bigger and better,
security will always be something that no one
really takes lightly.

If you've been concerned about Bluetooth security
in the past, rest assured that newer device will
offer bigger and better security.  Preventing
hackers from getting in is something every owner
is concerned about - and the manufacturer's are
very aware.

Other wireless technology such as Garmin GPS utilizes complex wireless systems that let you know where you are, on any place in the world.

How to Create Best Passwords

No sane person would ever like someone else reading her email. Or for that matter some other person using her password and breaking into a financial institution. You should, therefore, choose a strong, secure password in such a manner that would be a hard nut to crack for others and easy for you to remember. The more random and mixed-up you make it, the harder that it is for others to crack. Mind you, if your password is compromised, the password crackers will even take over your identity.

A password, if too short, is vulnerable to attack if an attacker gets hold of the cryptographic hash of the password. Present-day computers are fast enough to try all alphabetic passwords shorter than seven characters. We can call a password weak if it is short or is a default, or which can be rapidly guessed by searching a subset of all possible passwords such as words in the dictionary, proper names, words based on the user name or common variations on these themes.

On the other hand, a strong password would be sufficiently long, random, or which can be produced only by the user who chose it, so that 'guessing' for it will require too long a time.

For maximum security, the user should follow some simple guidelines:

1) Passwords should preferably be at least 8 characters long and not more than 14.

2) Passwords should contain a mix of numbers, letters, and special characters (%&3ac_ht4@m7).

3) Passwords should not contain a dictionary word from any dictionary, be it French, Spanish, medical, etc.

4) Each password should be different from the user's User-ID and any permutation of that User-ID.

5) New passwords and old passwords should differ by at least 3 characters.

6) Avoid picking names or nicknames of people, pets, or places, or personal information that can be easily found out, such as your birthday, address etc.

7) It's wise to stay away from common keyboard sequences, such as dfgh678 or abc345 .

8) Never form a password by appending a digit to a word. That can be easily guessed.

9) Avoid writing your password down or storing it on your computer.

10) Never share your password with anyone else.

6 Steps To Speed Up Your Computer

We live in a fast paced world and we are always looking for the fastest way to get things have done. We barely have been timing to wait for our burger at the local fast food restaurant, our coffee to brew, our microwave popcorn to pop, so who has been timing to wait around for a slow computer?

Barring and adding more RAM to your computer, there are 6 steps you can take to speed up your computer's performance. Most of these steps will allow you to speed up your computer, free of charge since they are applications already installed on your computer.

The first step, you should take is to empty the Recycle Bin. It's easy to do. Just point your cursor to the Recycle Bin icon on your desktop, right-click, and choose Empty Recycle Bin.

Next, open your Internet Explorer, go to Tools, Internet Options. Click on Delete Cookies, then on Delete Files. In the window that appears, check Delete all offline content and click OK. Once that's done, click OK to close the Internet Options window, and close your Internet Explorer.

Those two is, steps are the quickest, and simplest ones so that's why we got them out of the way first. Next, we'll be conducting a Disk Cleanup. To do this, click on Start, All Programs, Accessories, System Tools, Disk Cleanup. The disk cleanup functions will now begin calculating how much space you will be able to free up. Once it finishes, it'll give you a list of files to delete. It should already have some files checked, but you can go through the list and check off all the files you want to delete, then click OK.

Now it's time to do a disk defragmentation. This could be a long process so you should probably set this up during a time when you have got other things going on. For example, set it up, then go watch your favorite TV show, or go mow the lawn, or go workout. You get the idea. To begin go to Start, All Programs, Accessories, System Tools, Disk Defragmenter. Click Analyzes. If you are lucky, you'll get the "You do not need to defragment this volume" call-out, but more than likely, you'll have to click on "Defragment." If so, click on it, go do something else, and come back in an hour or two.

Once that's done, it's time to run a spyware scan. Most people don't realize how easy it is to get infected with spyware, so running periodic scans is highly recommended. You can use any anti-spyware program you choose. Just be aware that no one program gets rid of everything. To play it safe, you should run at least three different programs. You might be surprised by what they find. You may have had spyware running on your computer and not even know it. Once the scans are complete, and all that spyware is taken care of, it's time for the last step.

This lasted step is to run an anti-virus scan. I hope you have an anti-virus program installed on your computer. If not, I highly recommend you get one as soon as possible. Once the anti-virus program is set, go ahead and run it. This could take anywhere from 20 minutes to the couple hours depending on how many files you have on your hard drive so once again, set it, and then go do something else. Come back in about an hour.

Once all the steps are complete. Restart your computer and you'll be surprised at how completely nimble it now feels. It's a good idea to follow these 6 steps at least once per week (some steps you can even set up to be done automatically). By doing this, you will keep your computer performing almost like it did when you first bought it.

Blu-Ray DVD - What is ?

Video technology has increased significantly over the past years, and is continuing to grow at an incredible rate. Digital Video Disc's aka DVD's are the most likely the last big jump in consumer video technology that everyone is familiar with. To keep up with the ever advancing world of electronics a new format of video storage will be released soon called Blu-ray.

Blu-Ray is a next generation optical disc that will blow the socks off what we all know today: DVD. Conventional DVD's use a red laser that have long wave lengths, which limits the storage capacity on a disc. Blu-Ray uses a blue laser which has much shorter wave lengths. Because the wave lengths on the Blu-Ray are much smaller it can focus on a spot with much greater precision, allowing for data to be packed much more tightly than the red laser DVD's.

Blu-Ray discs can hold up to 50GB of information which 10 times that of a 4.5GB DVD. 10 times the storage will greatly increase the amount of information that we can save on any one disc and will change the way we save information. Dual Layer Blu-Ray discs will be able to hold up to 4 hours of High-Definition Video. High Definition video is going to hit big here, Blu-Ray is an example of a technology that is going to make it happen. 50GB is probably comparable to size of many of our hard-drives, and to picture having all that information on a small disc that we can slide into a pocket and take wherever we want is a bit scary.

Expect to see Blu-Ray replacing DVD and VCR over the next few years, following along with the transition of video to High Definition Video. Video isn't the only thing that will benefit from Blu-Ray technology; I would expect that it will also become the standard for PC and other types of storage.
