Many organizations believe that the security contractors often are not well suited to maintain the entire system because many contractors do not employ adequate IT-trained service technicians. That will change. At the same time, many IT service organizations are discovering that they can install and service IT-based security systems. Some of these organizations are rushing in to fill the void. IT-based integrated security systems must be maintained by a group that is competent in the maintenance of IT systems. That is often not the installing security contractor, whose competence is limited to the edge devices and software. I often recommend that maintenance of the IT infrastructure, operating systems, and software be placed under the authority of the organization’s IT department. Many TCP/IP-based security systems are installed without encryption or any other type of network security. I am fascinated by a security industry that does not secure its own systems. This could be the height of technical incompetence and moral (and possibly legal) irresponsibility. The ability to control the environment to the benefit of the users’ safety and security has profound effects on the welfare of the client, and it is a service of real value to the client’s constituents. A good example is that of irrigation systems. Upon triggering a perimeter alarm, if an intruder is proceeding across a grassy area, the intent of the intruder can be determined quickly by the remote triggering of the irrigation system. Only the most determined intruder will proceed across a large grassy area toward a target while in the embrace of a sprinkler system when a shorter path to escape is available. The use of building interfaces is limited only by the designer’s imagination. Wherever it can be imagined that a process could be facilitated by hand, it is probably possible to place that process under remote control from the console. In most cases, the security system is not rated as a fire alarm system and should not be used as such. However, for large buildings and facilities, it is useful to use the security system as a secondary annunciator for the fire alarm system. This does not replace the fire alarm system as a primary annunciator. Usually, the fire alarm annunciation panel will be located in a fire control room that is convenient to the fire department when it accesses the building. The fire control room may not be convenient to the security control room. A useful interface between the two systems involves placing a summary or secondary lamp annunciator within the security command center (this fulfills the requirement that the primary annunciator is the fire alarm system) and also interfacing the fire alarm system to the security system such that any alarm from the fire alarm system will be displayed on the security graphic maps. By interfacing the fire alarm system to the security system in this manner, it is assured that the code requirements are fulfilled while at the same time allowing for the display of fire alarms on a single graphical user interface map that displays all other types of alarms.

One video monitoring application uses on-site local networks and a second application uses the Internet and GSM Security camera , signal routers, and servers for remote site video monitoring. Security applications require complete integration of communication, video, alarm, access control, and fire to provide monitoring by the local security force, and corporate executives at a local or remote site(s). The integration of these security functions provides the safety and security necessary to protect personnel and assets at any facility.
The clarity of the picture transmitted using fiber optics is now limited only by the camera, environment, and monitoring equipment. Fiber-optic systems can transmit signals from a Wireless Security Cameras to a monitor over great distances— typically several miles—with virtually no distortion or loss in picture resolution or detail. The system uses an electrical-to-optical signal converter/transmitter, a fiber cable for sending the light signal from the camera to the monitor, and a light-toelectrical signal receiver/converter to transform the signal back to a base-band video signal required by the monitor. At both camera and monitor ends standard RG59/U coaxial cable or UTP wire is used to connect the camera and monitor to the system. The economics of using a fiber-optic system is complex. Users evaluating fiber optics should consider the costs beyond those for the components themselves. The small size, lightweight, and flexibility of fiber optics often present offsetting cost advantages. The prevention of unanticipated problems such as those just listed can easily offset any increased hardware costs of fiber-optic systems.
Broadband fiber-optic components are much more expensive than cable. They should be used when there is a definite need for them. Note also that video signals must be digitized to avoid nonlinear transmitter/receiver effects. Why use fiber-optic transmission when coaxial cables can provide adequate video signal transmission? Today’s high-performance video systems require greater reliability and more “throughput,” that is, getting more signals from the camera end to the monitor end, over greater distances, and in harsher environments. The fiber-optic transmission system preserves the quality of the video signal and provides a high level of security. The information-carrying capacity of a transmission line, whether electrical or optical, increases as the carrier frequency increases. The carrier for fiber-optic signals is light, which has frequencies several orders of magnitude (1000 times) greater than radio frequencies, and the higher the carrier frequency the larger the bandwidth that can be modulated onto the cable. Some transmitters and receivers permit multiplexing multiple television signals, control signals, and duplex audio onto the same fiber optic because of its wide bandwidth.
With such rapid advances, the security system designer should consider fiber optics the optimum means to transmit high-quality television signals from high-resolution monochrome or color cameras to a receiver (monitor, Rear Mirror Camera , recorder, printer, and so on) without degradation. This section reviews the attributes of fiber-optic systems, their design requirements, and their applications. While the balanced transmission line offers many advantages over the unbalanced line, it has not been in widespread use in the video security industry. The primary reason is the need for transformers at the camerasending and monitor-receiving ends, as well as the need for two-conductor twin-axial cable. All three hardware items require additional cost as compared with the unbalanced single-conductor coaxial cable. The use of UTP transmission has become a popular replacement for the coaxial cable, or fiber optics.More information at http://www.jimilab.com/.

The vast array of home security products available on the market today can be dizzying. Home security products can be wireless or hard wired, optional or required or simple or complex. Determining which home security products you need can be difficult enough and it becomes more complicated when you have to choose between the assortments of models that are available for each product. Generally speaking, hard security alarm systems are lower in cost compared to the wireless system, but it consumes more time to install and it requires the ability to hide wires in walls for a neat installation.
Wading through all of the available information can be overwhelming. For this reason choosing only the most basic home security products can greatly simplify the process.The control panel, keypad, access control sensors and an audible or visible alarm are some of the basic home security products that are used in just about every home security system. The control panel is one of the most important home security products available. This is the heart of any security system. All of the wiring for the other home security products meets at the control panel and the entire system is tied together at this location. Without this valuable component, the security system would not function properly.
The keypad is another of many home security products that exists in just about every security system. The keypad is where the homeowner interacts with the system. The system can be activated and deactivated at this location. The keypad is also where the system displays messages for the homeowners. If there has been a breach of security while you were away or if one of your home security products is malfunctioning, the keypad will display these important messages for you. The other purpose that the keypad plays is to display the current status of the system.
Access control sensors are other home security products that are critical to the function of a home security system. These home security products are used to detect if a door or window is opened while the security system is activated. When these sensors are triggered an alarm will sound either immediately or on a delay. The reason that most security systems incorporate a delay is to enable the homeowners to deactivate the system upon returning to their home. Finally, an audible alarm and strobe lights are other home security products that are commonly used. These home security products can be used separately or in conjunction with each other. The importance of these components is that they alert the homeowners as well as their neighbors to a possible intruder. In most cases a triggered alarm is enough to cause the burglar to vacate the property as quickly as possible. Not all home security products are necessary. Many home security cameras are optional while home security products such as the control panel, keypad, access control sensors and audible or visual alarms are necessary for the system to function properly.

the Small GPS Tracker that’s designed to work with Street Atlas USA and other map programs that use GPS data. (You can use other types of Small GPS Tracker with Street Atlas USA, too, but the JIMI is designed to work with the program with a minimal amount of setup.)You can connect the to a laptop via a Universal Serial Bus (USB) cable, serial cable, or a PowerPack that supports Bluetooth wireless.communications. After you have the GPS receiver hooked up and Street Atlas is running, the two general modes of operation areGeneral navigation: Street Atlas USA processes the received GPS data and displays your current position on the map with a series of dots that shows where you’ve traveled. As you move, the map automatically moves to show your position. In addition, your speed, direction of travel, and GPS satellite information is shown in the program’s GPS tabRoute: After you create a route ,in addition to the general navigation features, Street Atlas USA displays turn-by-turn directions onscreen, informing you how far your destination is and the travel time to your destination. If you have the voice feature enabled, Street Atlas USA announces the directions; you can choose from several different types of voices.Street navigation software coupled with a laptop and GPS receiver isn’t your only option to stay found while driving through the asphalt jungle. GPS car navigation systems are starting to become popular as factory-installed options and third-party add-ons for cars and trucks. These systems are streamlined versions of street navigation programs, offering basic navigation features such as real-time map display, address searches, and route planning.
Car navigation systems range from portable, handheld Car GPS Tracker that are equally at home on the trail or the road to systems permanently installed in a vehicle. Some of the more sophisticated products use gyroscopes, connections to the Vehicle Speed Sensor (car-speak for a speedometer), and three-axis accelerometers to provide speed and distance information when a GPS signal is temporarily lost; such as in tunnels or urban areas with tall buildings.I have to admit I’m not a true road warrior and don’t spend lots of time in my car. However, I did have a chance to try out a GPS navigation system for a while and was pretty impressed. mounts on your dashboard and is portable so you can easily transfer it from one car to another. The version I tested had an internal hard drive that was preloaded with street maps of the entire U.S., so you can just plug it into your cigarette lighter and go. This is perfect for a business traveler who just flew into a city he’s never been to before and has to spend the next couple of days in a rental car trying to find his way around. Routes are calculated in a matter of seconds, and a large, high-resolution map screen keeps your progress updated. And with a touch screen, voice prompts, and a simple user interface, even my nontechnical friends and family members were able to figure out how to use it in no time.More information at http://www.jimilab.com/.

The heightened awareness for security has given rise to a more consumerfriendly grade of video monitoring gear for your wireless network — this stuff used to be the exclusive domain of security installers. You can get networkaware Wi-Fi video cameras that contain their own integrated Web servers, which eliminates the need to connect a camera directly to your computer. After installation, you can use the camera’s assigned Internet Protocol (IP) address on your network to gain access to the camera, view live streaming video, and make necessary changes to camera settings.
Network cameras are much more expensive than cameras you attach to your PC via a USB connection because they need to contain many of the elements of a PC to maintain that network connection. Expect to pay from $100 to more than $1,000 for network cameras; the more expensive versions offer pan-tiltzoom capabilities and extra features such as two-way audio, digital zoom, and motion detection. (The average price for a well-equipped camera is $200.) JIMI 3G Wi-Fi Camera can check at any time through your smartphone to monitor your house and you can relax in the knowledge that should anyone break in you'll instantly be alerted with frame grabs of the intruders sent to your mobile. In peace of mind you could check what is happening in the house through 720P live video stream. Even when the power is cut off, the internal battery is ready for up to 4 hours’ usage to detect abnormal motion/voiceaided by the PIR sensor.
Installing a wireless network camera is incredibly simple. These network devices usually sport both an RJ-45 10Base-T wired network interface along with an 802.11b/g air interface. Installing the camera usually involves first connecting the camera to your network via the wired connection and then using the provided software to access your camera’s settings. Depending on how complicated the camera is (whether it supports the ability to pan, to e-mail pictures on a regular basis, or to allow external access, for example), you may need to set any number of other settings. To allow anyone from outside your home’s LAN to view your camera feed directly (that is, not from a window pane published on your Web page), you need a static WAN IP address. Although you can probably get such an address from your broadband connection provider, it will probably be pricey. More likely, you’ll use a dynamic DNS service (DDNS), which allows you to assign a permanent Web address to the camera. A DDNS is easier to remember than an IP address and is static. Your camera vendor should help you do this as part of the setup process.
Another area of wireless activity is home control. If you got excited about going from the six remote controls on your TV set to one universal remote control, you ain’t seen nothing yet. The problem with controlling anything remotely is having an agreed-on protocol between the transmitter and receiver. In the infrared (IR) space, strong agreement and standardization exist among all the different manufacturers of remote controls, so the concept of universal remote control is possible for IR. But there has not been the same rallying around a particular format in the radio frequency (RF) space, thus making it difficult to consolidate control devices except within the same manufacturer’s line. And then you have issues of controlling non-entertainment devices, such as heating and air-conditioning and security systemshttp://www.jimilab.com/products/wireless-home-monitor.html. Those have different requirements just from a user interface perspective.
