We currently have Brink’s security system and pay Comcast for a VOIP line for the security system to use. We don’t use that line for anything else and I feel that it is a waste of money. Is there any types of home security system that works through broadband or wi-fi? Thanks.

VoIP security has been called in question recently, though there is little evidence to indicate that VoIP security is any less than conventional telephony systems.

VoIP voice data is transmitted via a packet-switched data network using IP. VoIP systems can carry a significant higher number of calls, and very much faster, than traditional PSTN networks due to compression of the voice packets, modern broadband technology and a number of other gateway developments which have reduced the previous packet delivery problems to an extent that the protocol is now a viable mainstream telephony solution to most business needs.

VoIP security should therefore be shown to be at least as effective as that of traditional telephone systems.

There is actually very little difference between VoIP security and that required for any other type of data transmission system. Look on it the same as you do your email system. The same as your office LAN if you have one. You probably have a system in operation whereby only authorized personnel can use certain aspects of the network. VoIP security can, and do, use the same techniques.

However, having said that, let’s have a look at potential weak points in VoIP security that budding hackers may see as good points of attack.

IP PBX CALL MANAGEMENT BOXES

PBX stands for Private Branch Exchange, and is piece of software running on a server. It’s function is to deal with all the switches and connections involved in the telephone system. These can be attacked by hackers or viruses which could compromise sensitive data. VoIP security systems are designed with this risk in mind.

PBX equipment should be placed behind firewalls, locked down and regularly monitored for unwarranted intrusions using intrusion-detection software. It is also possible to put the server in a different domain from the rest of the system, making it much more difficult for intruders to reach. PBX security is a basic aspect of VoIP security systems

GATEWAYS AND DATA PACKETS

The gateway’s job is to convert voice to data packets, transmit them then receive and convert the packets back into voice. These are a potential VoIP security risk in that thy can be hacked into unless there is an access-control system in place to prevent unauthorized people from accessing the system. VoIP calls should only be permitted to specific people, and most good VoIP security systems allow only authorized user to operate VoIP systems under password control.

The data packets themselves can be hacked into using data-sniffing techniques. This can be a serious VoIP security risk and packet sniffers, as they are often called, capture binary data passing through your network and can reroute it to a computer on another network for decoding into a readable form. In order to do this, the ’sniffers’ has to be on the same network wire as the packet is using to reach its destination. The problem in installing an effective VoIP security system is that there is usually a lot of information passing at any one time, and the hacker has a higher probability of getting useful information than from a conventional telephone system.

Encrypting VoIP traffic and routing it through a virtual private network would reduce the VoIP security risk, and most corporate systems have multiple encryption layers for external messages. Internal security could be improved by running internal VoIP messages through this corporate network. Small businesses should seek the advice of their supplier, or of a security expert if they feel that they may be subject to such attacks.

However, VoIP security advisors can point small to medium companies in the right direction. Corporate VoIP security is generally not so much problem in that it is normally contracted out to expert advisers.

In the final analysis, however, there are no real differences between VoIP security and the normal security concerns associated with any data network service, such as normal office internet and email LANs. The security firewalls and restricted access to use, common on these systems, should suffice to deal with VoIP security

We all feel more secure when we are positive no one can gain unlawful entry into our homes. Whether we are at the grocery store, away on vacation, or sleeping soundly in our beds – safety is always a priority. Because of this need, home security systems have been on the market for almost a hundred years. Recent advances in technology, however, have made buying a home security system about as complicated as it can get, so many homeowners tend to buy the wrong one, or go without.

With the advent of CCTV, video is now the best security option possible. Loud alarms, flashing lights, heavy bolts, and live feeds to the local police department all have their place in the security business, but without the all important video, most bad guys are never caught.

Professional thieves know that it takes at least five minutes for police to respond to a home invasion. Within that time frame, even with a loud alarm going off, they can quickly find your jewels, money, and high electronic gear – and be gone – before help arrives.

A silent alarm provides even less protection. All that does is give the burglar more time to rob you – or cause you bodily harm. The police still need to come, and not even the neighbors are aware of what is happening because no one can hear the alarm blaring.

What you need and what the police want is video! They need to see the guy’s face! If they are lucky they’ll even see the getaway car and a license plate, and perhaps his buddies who helped.

As long as you are adding video cameras, make sure you have cameras that include motion sensors – these cameras follow movements. There’s little sense in installing video cameras and then finding out that all the action was out of camera range! Make sure you have at least a camera at the front door, and then put alarms on each window. A super effective system will have cameras and alarms at each entrance, and cameras and audio that cover the entire property.

Additional cameras come in handy when additional crimes are committed over and above theft. If a home invasion includes an assault or other crime, the police will need to rely on these tapes in order to collect evidence. Usually these systems only include video, and not audio. Many times video is enough to find and convict someone, but in some cases, audio is even more important – especially in situations where certain actions aren’t caught on tape, but accompanying audio is just as or even more incriminating. A bare bones beginner set up should at least have a camera at all entrances (front, back, garage, etc.), one in the kitchen, family room, and entranceway to the bedrooms (hallway, pathway, stairs, etc.).

Every now and then we will have the need to search somebody’s data. It is probable that you may have lost a previous associate and the only ties you have to them is an previous mobile phone number.

1. You will not have to pay private investigators for their facts of where they discover the data.

2. you will not have to compensate them for accessing public records. The price for accessing this sort of info can run into the thousands.

The same data that private investigators are able to retrieve is no longer private. This information is obtainable to anybody with an online connection through a program called Reverse telephone Detective. What that means is that you can play the part of a private investigator by simply having somebody’s cell telephone number.

The reverse phone search system will in addition provide you with name, address and family members in your lookup. So in essence you will be cutting out the center man, conserving some cash and obtaining results at your fingertips.

Lessen all the private investigator fees today by doing a phone number lookup yourself. Save tons of money with your private reverse phone number lookup.
