How to Sweep a Room for Electronic Listening Devices

Learning how to sweep a room for electronic listening devices is not as complicated as you may think and once you learn the basic steps you will be able to sweep a normal sized room in just a few minutes. Much of the time will depend on the bug detector you are using as your sweeping device.

The process to properly sweep a room is the same whether your audio bug detector has some type of strength meter or uses audio alarms to alert you to any radio frequencies it may detect.

Wireless Network Detector

You can decide whether you start on the left or right of the entrance door since what you are basically going to do is treat the room like a grid and go row by row until the room is completely and thoroughly swept.

Start your sweep by facing the wall and stand back about 5 feet from it. Hold your bug detector in your outstretched arm and start to slowly move your arm back and forth from side to side. Depending on your detector you will either hear a sound or see the strength meter move if you pick up any signals during the sweep.

If your bug detector should find a signal you will need to determine which way the signal is coming from by using a process of elimination. The stronger the signal the more your detector will react so you can narrow it down by continuing to go side to side until you see which way the signal is the strongest.

Once you narrow down the direction move a few steps in that direction and sweep side to side once again to determine which way the signal is the strongest. Repeat these steps until the signal is equally as strong on both sides of you.

Once you are in front of the source you can use slow side to side movements to narrow it down to the exact point of the signal. Depending on where the bug is located, you may need to move your arm up and down as well in order to find the exact point of the signal.

If you find you are unable to narrow down the exact source of the radio frequencies if may be due to those signals bleeding in through the walls from outside of the room. Although a wall can block much of a radio signal some of it will generally still get through.

You can verify this if the signal is the strongest when you are in front of the window. If there is no window you may need to go outside and walk around the building if at all possible.

It sounds a lot harder than it is but after you have done it a couple of times you will be able to sweep an entire room in just minutes and be sure no one will be able to listen in to the conversation within the room.

IP Camera

The most common benefit of an IP camera is the ability to view live video over the Internet from anywhere in the world. This offers the advantage of monitoring a location or property while customer is not physically there to observe activity for suspicious behavior. It is possible to view CCTV cameras over the Internet however additional hardware and software are required. An IP camera has this ability built-in so only an Internet connection is required without any software.

These camera enclosures come with various mounting types. These include pole mounts, wall mounts, ceiling mounts and corner mounts. These different types of mounts allow user to install the enclosure in various environments easily and effectively. Some enclosures are sold with mounts, though some are sold separately. This allows user to use the same enclosure in various different applications by purchasing the necessary mountings for each enclosure installation.

Wireless Network Detector

The New IP cameras that are just being recognized are actually only just emerging from the market background. The top models in the range are very good as they bring in a passive, integrated white light and embedded, programmable speaker into the same compact unit, along with a whole new range of specs that are fully optimizable with great options including: Two-way audio 'click-to-talk' button, Controllable auto-flip windows, Begin recording by simply right-clicking in a camera view, Dynamic action buttons - assign outputs, full range PTZ presets, motion events and views as actions to joystick buttons and keyboard shortcuts, Wiper equipment and be activated from the smart client or DVR, AVI export with audio automatically included, Digital zoom within images is now a default for fixed cameras which improves viewing details, 17 languages in the software.

Although most IP cameras come with some form of built-in motion detection, the unpredictability of this technology prevents it from being used in most applications. Using motion detection would also require that there be some way to arm and disarm the cameras so that they do not send images when people are legitimately moving around the protected premises. Due to the familiarity and simplicity of arming and disarming an alarm panel, by far the best option is to have the alarm panel trigger cameras only when it is armed. This way, images are only sent to the server in the event of alarm activation.

One main use of outdoor IP camera enclosures is to protect the camera from weather that would destroy the camera if unprotected against the elements of rain, snow, heat and cold. When looking for an outdoor IP camera enclosure, examine what type of weather conditions the enclosure and camera will have to withstand. If the enclosure will be in an open area which would allow rain to fall on the top of the enclosure, be sure to purchase an enclosure that is properly sealed to avoid moisture penetrating inside. They will want to make sure the enclosure offers proper airflow for the camera. A completely sealed enclosure with no airflow could potentially overheat their camera.

This camera can be used to check whether employees are using the given time to add to the company's prospects and can be used for parental control and allows the parent to keep a close eye on his teenager. Since some people find the practice unethical, it becomes necessary to install these cameras only when the situation is dire and no other option is available. Even though employees protest when such cameras are being set up, one cannot ignore the fact that a business cannot be run on mere trust. Surveillance, therefore, becomes necessary. Employees tend to dip into the company's account and extract money for personal needs. When such a theft takes place, it becomes difficult to point out who the culprit is. This makes it all the more important to consider an IP camera.

Wireless security cameras technology typically involves a battery-operated camera. It does not store recorded images in its internal memory. What it does, instead, is transmit signals to a receiving device that may be located as far as up to 500 meters away. Remote monitoring can then be done by hooking up the receiver to a television. At present, there is a wide choice of models available for wireless security cameras. So, you have an option between a battery-operated and an AC-powered one.

Some IP cameras also come with a BNC/Analog output allowing customer to connect IP camera to their existing CCTV system. This would allow them to connect the IP camera to their DVR recording station and still have a network connection attached allowing for remote viewing and recording to a PC or offsite location. Be sure to verify the IP camera has the ability to send video to both the BNC/Analog output and through the network simultaneously.

Wireless Antenna's: 6 Reasons to Use a Directional Antenna

Most if not all wireless access points and wireless routers come with the standard omni -directional rubber duck wireless antenna. Omnidirectional antennas used in the wrong situations are such a waste of money and can be a secuirity risk. Directional antennas can be used to focus your signal where it's needed.

Reasons to use a directional antenna:

Wireless Network Detector

1. Save money- Long hallways are common in office buildings. Don't try to use the defualt Ominidirectional antennas on a long hallway. You will have to purchase more equipment to extend the bubble of coverage. One directioal antenna with a 60 degree focused signal would be able to extend your coverage area twice as far

2. Security- When your wireless signal bleeds outside your operational area you will attract hackers, crackers, leeches, wardrivers and social engineers. The higher the DBI on the antenna the more focused your signal is, so if you have an 8dbi antenna your probably looking at a 60 degree cove or signal comming from your antenna. A 14dbi antenna might have a 30 degree focused signal that might not provide the width of coverage you need and it might send your signal to far.

3. Less Equipment - Cut down on your epuipment that you have to install and manage

4. Shoot Signals around corners - Take an access point, two panel directional antennas and a signal splitter ( The splitter will allow you to hook two antennas to one access point). Now you can mount the directional antennas on a corner mount, shooting the signal down two hallways at onced. This solution is very common and will save you money.

5. Distance - Omnidirectional antennas usally have half their signal wasted by walls. Directional antennas don't have that waste they focus their signal in one direction thus extending your signal much farther that an Omni. There are two different types of directional antennas: directional and highly directional.

6. Smaller Profile - Omnidirectional antennas are hard to blend into an office enviroment or building. They stick out like a sore thumb and advertise your wireless network to everyone. Directional antennas like the panel type have a smaller profile and often look like lights or smoke detectors.

This articles purpose isn't saying that there isn't a purpose for omnidirectional antennas. What I"m saying is that most people don't even think of changing their antennas after purchasing their wireless router or access point. My next article will discuss the advantages of combining directional antennas and Omnidirectional antennas

IP Cameras Vs CCTV Cameras - Part Two

In our previous article entitled "IP Cameras vs. CCTV Cameras - Part One," we discuss the advantages of Remote Viewing, Recording to Remote Locations, Wireless Functionality and Motion Detection with Video Analytics. This second article will discuss other advantages that IP cameras have over traditional CCTV cameras.

Compatibility

Wireless Network Detector

Most IP camera recording software supports a wide range of IP camera models and manufacturers. This allows you to mix and match IP cameras in your installation to create a custom surveillance solution that fits perfectly for you.

Let's say you wanted to setup three IP surveillance cameras, one viewing a parking lot, one watching your front lobby and another monitoring the rear entrance of your building. You could put three different IP camera models - even manufacturers - in this installation. You could go with an IQEye 755 5.0 MegaPixel IP Camera in the parking lot to monitor vehicles and provide a high quality image to zoom in on license plates. You could put a Wireless AXIS 207W with audio in the front lobby to minimize cabling requirements and to provide audio surveillance. Lastly, you can use a Sony SNC-RZ25N PTZ IP Camera with an outdoor enclosure to monitor the rear entrance and have the ability to pan/tilt/zoom the camera to needed areas.

All three IP cameras can be easily connected to the local network and configured within the IP camera recording software to monitor and record each individual camera.

BNC/Analog Output

Some IP cameras also come with a BNC/Analog output allowing you to connect the camera to your existing CCTV system. This would allow you to connect the IP camera to your DVR recording station and still have a network connection attached allowing for remote viewing and recording to a PC or offsite location. Be sure to verify the IP camera has the ability to send video to both the BNC/Analog output and through the network simultaneously.

PoE Power over Ethernet

Power over Ethernet (PoE) is the ability to power your IP camera and provide network activity via one RJ45 network cable. This provides an easier installation and lower cable installation costs as this eliminates the need for a power cable to be connected to the camera. To take advantage of this technology, make sure your IP camera is PoE compliant. A PoE network router/hub or Midspan will be required to provide power to the camera via the RJ45 network cable. PoE kits are also available which provide power via network cable when you do not have a Midspan or router/hub. One PoE kit will be required per camera and will need to output the correct power requirements (5V, 9V, 12V, etc.).

I/O for Card Readers, Alarms, etc.

IP cameras can easily be added to existing security including card readers, alarms, glass breakers, access control, etc.. The IP camera can be set to receive an input from these devices which can then tell the camera to record video when a specific event is triggered. Outputs can also be set where if the IP camera detects motion, a signal is sent to the alarm to create an audio siren or alert.

Conclusion

We hope Part One and Part Two of "IP Cameras vs. CCTV Cameras" has educated you in the advantages of IP over CCTV. It is best to know what options exists for you before making a purchase so you can effectively monitor your home or business.

Telemetry - How To Choose The Right Telemetry System For Your Business Requirements

Telemetry is a broad subject and it is applicable to many different areas: from safety monitoring in nuclear plants, to the migration habits of endangered species. It is widely used in big projects like power plants, sewer control and purifying water plants; and their versatility has found diverse applications in the private arena. Thanks to the advances in technology, telemetry is used successfully in chemical plants and the food industry; this used to be a challenge in the past as stainless steel and concrete interfere with some wireless signals.

Measuring of physical and chemical parameters in tanks are areas where telemetry has huge applicability. Due to the diversity of configurations, there is not a one size fits all solution. When shopping for the best telemetry system for your particular business requirements, you need to have a clear idea of your conditions beforehand. There are seven main elements involved in the implementation of the system, if you clarify your needs in these seven points, it will be very easy to choose the right configuration:

Wireless Network Detector

Sensor/hardware optimization: The sensors to be used will be affected by the nature of the substance in the tank. It is not the same to have acid, fuel or syrup. So take note of what is in the tank.

Sensor integration: Depending on what you want the sensor to measure and the conformation of your tanks, the best position to place it will vary. You also need to specify if you are using the system for a single tank or multiple tanks. The main options for positioning in site are:

Flow meter: in or out Bottom: differential pressure Top: ultrasonic or contact Contact: high, low or overflow

Form of communication/signal: The optimal form of communication will be determined by the location characteristics and accessibility of signal. The two main groups are short range wireless connection or long range wireless connection.

Short range: If your tank is close to a LAN(Local Area Network) or a WAN (Wide Area Network), you can use low energy signals. Some of the options available are: 802.xx protocol, Wi-Fi and short haul RF. Which one is the best depends on the obstacles in the signal´s path and their wave absorption power.

Long range: If the tank is in a remote place or the short range signals are absorbed, some of the options are digital mobile technology (GPRS/CDMA), analog cellular, satellite or a combination of them.

Power: The communication devices need energy to operate. If your tank is local, pay attention to the power configuration and see if you can hardwire or if you need a battery. If the tank is on a remote location, you can you use a battery or you might need solar charging.

Communication frequency/Direction of signal: The optimal communication frequency will be consequence of the nature of the data you want to analyze and store; and if you want the system to perform actions or not. If you are using telemetry for transmitting data to a central hub for security or analysis, then you will need one way communication. If you want the system to be able to respond to certain signal and generate changes (open/close a valve for example), you need two way communication.

Once you choose one or two way communication, there is still the actual transmission frequency. Some of the options are: continuous, minutely, hourly, daily, monthly or alarm activated (usually high or low level).

The communication frequency and direction of signal will affect the choice of the emitter and receiver hardware, and partly the management software used or custom developed for you.

Storage and Management of information: If you have a LANor WAM, you can store and run the analysis of the information on your own network. In this case, at least one of the computers of the network will be dedicated to this endeavor, and the reception hardware will be attached to it. If, on the other hand, people from different geographical locations need access to the information, then you might opt for a hosted solution. Hosted solutions allow for 24-7 access via internet, so it becomes location independent.

Budget: There are hardware choices in different price ranges. As rule of the thumb, the smaller the up-front cost the bigger the long term cost. The total cost of the project will be given by the hardware itself, installation, life of the equipment and maintenance costs.

These are the seven main elements to analyze when looking for a telemetry system for your business requirements. If you search for a service provider with this information at hand, the search will be much more efficient and you will be able to take informed decisions fast.

Is A Computer Security Camera Right For You?

More and more people are seeing the wisdom of consolidating many of the electronic components around the house through a home based computer network. Among these functions is the operation of the home security system, including the cameras. There are actually some great reasons to drive your home security through your computer.

One of the best reasons to link your home security system with your home computer network is that you will expand the functionality of the Surveillance cameras are placed at strategic locations around the interior and exterior of the house. A security camera computer can be programmed from your main computer at home so that it is possible for the equipment off and on. At the same time you can use the cameras so that the computer lets you know when someone is approaching the house in which you scan the visitors and determine whether it is someone you want to see. As a way to deal with unwanted visitors, this agreement is an excellentsolution.

Wireless Network Detector

Another advantage of using security cameras that are linked to your computer is that they are easy to upgrade. Often, new releases of the cameras will still run with older software or with a simple update to an older program. The cost to update a system of this natures is far less than with stand along security systems. After your initial investment, it is easy to obtain the updates as well as replace the cameras when and as you desire, without spending a lot of money.

A third reason to consider integrating your security and the cameras into your home computer network is the ability to arrange for several combinations of pre-programmed events. For persons who are going to be out of town for several days, this is very important. It is possible to arrange for automated notifications to take place in the event that someone attempts to enter the home through any of the protected doors or windows. When a camera picks up the activity and the entry to the home is breached, the automated system will dial out to your security service, or to the local authorities. The software also records the data automatically, so you can review the activities when you get home.

If you have been thinking about installing a security system in your home, or upgrading your existing system, it is well worth the time to check into a computer integrated system. With a number of attractive functions, you may find that this sort of approach to home security is just what you need.

Linksys E1000 Review

There are three E-series router Linksys: the E1000, E2000, E3000, and the '. The E1000 is the cheapest and most low end of the series of routers. But only because it costs less, does not mean it's useless. This wireless router must be reliable and easy to use, but you will not get the choice and luxury features of the E2000 and E3000.

Let's see what comes standard on this bad boy. It comes standard with all wireless signals, you must:802.11n, 802.11g, 802.11b, 802.3, 802.3u and. Security features WEP, WPA, WPA2, and up to 128-bits. It makes up to 300 MB / s as well.

Wireless Network Detector

For the person just looking for a good light on a router Economic and go straight to the Internet to try to beat it without connecting every piece of electronic equipment in their home on the router is all you need.

Now let's look at what we have discovered the advantages and disadvantages of the system to be.

We begin the on-offAs it is easy to install. Unlike the old days when you had the IP addresses manually and macro-enter the new numbers are like this router with the simple installation CD, and as the name suggests, it is very easy to install. Eject the CD in and follow the onscreen instructions and the configuration of the router will be within 5 minutes, there is much confusion with something so simple. The higher-end products can get a little 'complicated, but they also have a simple installation now.Although it is a basic router, there are some advanced features that we would like to talk. The child is easily installed and can limit what is the rating and how long to use the registered Internet users. Separate networks can be set to one for adults and one for his children, children with access to only G-rated share Internet and the limitations of time, while the adults-network limit. Finally, as with all Linksys router is looking for the E1000 with a very thinDesign, compact and there is no attack in the antenna of things to have, because they are all housed inside

For such a low price, which is a pretty big list of professionals, let's see if the cons outweigh the pros. First, there are no Gigabit ports, that is not possible to link directly to the computer to the router itself, it only does wireless (which is not much of a problem, because we are dealing with wireless router). With a price so low that evenVictims USB ports that allow us to print a configuration of wireless network, so you can print from anywhere in the house and choose the printed material would be from the router. Finally, the area is more than acceptable for a budget, but if you're out trying to enter the building you are designing a radio signal may have a problem with speed.
