The Best DVR for Video Surveillance

Filed under: Security Info, Web of Blogs, World Of News @ 5:04 pm

In a perfect world, there would be no need for surveillance. Everyone would do their work, no one would steal, lie, cheat, or vandalize, and nothing would need to be watched or guarded. That would be nice wouldn’t it? But in this world, our world, there are many things wrong, one of which is the habit many people have of doing all the bad things listed above and many more. That’s why surveillance is so important, and why it’s so important for individuals, businesses and corporations alike to invest in the best technology for their security when it is needed.

Security cameras is one of the most effective ways of keeping an eye on areas and things that are left alone or that need special guarding. Video surveillance has been used for a long time, almost ever since video technology has existed, but the technology has gotten much better since it was first invented. Presently the best video surveillance systems are DVR or digital video recording based, meaning that everything recorded goes into a computer for review and storage.
DVR is much better than older ways of taking video surveillance including VCR techniques. With VCR the process was much more analogue and required a multitude of VCR tapes that needed to be changed almost constantly. In those times video surveillance was a much more hands on job, and on top of it after all the work you put into it the video quality was relatively poor. With DVR all that changed. DVR used a DVR card to connect to a computer. A DVR card like a Geovision DVR, one with high quality and fast processing, can connect a variety of cameras, sometimes as many as 16 or more, into a single computer for easier recording and viewing. With this completely digital way of capturing footage your whole video surveillance process becomes much easier. For one thing, you don’t have to be changing tapes every 6 hours, and you can easily stream and archive the data with only the click of a mouse.
You can keep months of video footage on a large hard drive and that way have lots of video to reference and review in time of need. Best of all this technology is much more stable and harder to break than the old system, and you have much less chance of breaking it because you will hardly ever be moving it. On top of that when you are using Geovision DVR cards you can access it from a variety of places. You can check your surveillance cameras from a computer café PC or a friend’s computer. If you need a good surveillance system then there is no better option you can choose for your money than a Geovision DVR card. A DVR card of that quality means you get the best product for your money, and it’s a whole lot easier to use and install than most other options.

The Differences between a Soft, Hard and Transmit Phone Tap

Filed under: Security Info @ 3:20 am

The phone tap is one of the more common types of surveillance activities. The military, government agencies, and police use phone taps to listen to conversations. Additionally, there are private investigators and amateur spies who each use some sort of phone tap to obtain information. It is even possible for regular people to participate in phone tapping, if they have the right equipment. This can be helpful in amassing evidence in divorce cases that my include allegations of infidelity or in instances of feeling threatened by someone else.

In order to set up an effective phone tap, however, it is important to know what types of taps there are, as well as what each kind of phone tap does. You should carefully consider your situation and your budget, and then choose the type of phone surveillance that works best for you.

Soft. This type of phone tap is becoming more and more prevalent as technology advances. This is because a soft tap uses special listening software. The idea is to tap into the phone system of a company or a home. Even tapping into the software at the phone company (even many land lines are now serviced at the phone company by digital lines) can be done. By modifying the software that acts as the “switchboard and eavesdropper can obtain access to conversations. It is fairly easy to find this sort of phone tap, as long as you have unrestricted access to the system that is affected by the tap.

Hard. The hard phone tap is one where there is actual physical contact with a wire. For instance, a secondary wire is attached to a PBX cable or to a transfer box containing the desired line. A third location receives the signal via a bridge. There is no way for the parties on the line to detect any interference, and it is very difficult to use a bug sweeper to detect a hard phone tap.

Transmit. A transmit phone tap is one that sends information using airwaves. This means that there is no hooking into a line and there is no need to hack into a software system. However, a transmitter gives off a great deal of RF energy. Nearly any person can use a bug sweeper to detect this type of phone tap.
