Wireless Cameras Guru: IP, GSM and 3G to Be the Future of Wireless Security

There are much technological advancements today but none has made as much impact to how society communicates as the development of mobile communications. Starting with two-way radios, mobile communications evolved into the 1st generation ( 1G ) analogue mobile phones and later to the second generation ( 2G ) mobile technology that runs on digital networks.

2G mobile technology ushered in the emergence of GSM or global System for Mobile Communications which featured a couple of advantages made possible thru digital systems. This includes a few benefits you are enjoying today such as text messaging and net connectivity. 2G further developed into 3G or the 3rd generation of mobile technologies and standards that are quicker and have more bandwidth than 2G technologies which may ultimately set the pace for the way ahead for wireless security.

Mobile Technologies and Wireless Security Camera Systems

3G has made it simpler for multimedia information to be sent through mobile and web networks, permitting folks to share more and higher quality pictures, video and other information from any location across the globe even when folk are on the go. This capacity sets 3G telephones apart from other telephone technologies that existed over time.

3G, IP and GSM technologies have also revolutionized the way wireless security systems are built at this time. You can now have wireless cameras that will employ broadband capabilities in these networks to send higher quality images and video footages from remote locations. Wireless cameras can now be utilised for most urban video security and surveillance applications in public places, commercial establishments and economic locations. These systems can be utilized much more easier, less time and less set-up and operational costs.

The following are some of the most recent wireless security camera system configurations that utilize the newest in mobile communication technologies available.

* IP CCTV cameras

IP or Internet custom cameras use digital camcorder systems to transmit data and other information to any PC in the security network thru the web. IP cameras can have a network video recorder ( NVR ) built in which can process and record photographs and video footages right into any digital storage media drive built into the system. The NVR can also be centralized with all wireless cameras, each having its own IP address, remotely connected and sending all feeds for centralized recording and security management.

IP video cameras remain very fashionable among those requiring video surveillance and wireless camera systems. Costs have gone down quite significantly to very affordable levels, making it quite less complicated for you to get such systems or enter into an online business reselling such units.

* GSM CCTV cameras

Wireless video security cameras that are placed in locations with some or no web connectivity can utilize GSM connectivity instead. These GSM CCTV cameras are immediately attached to your mobile phone via the GSM network, sending you cautions like SMS, MMS, or email complete with videos and photographs should there be any intrusion into your properties under surveillance.

The marketplace for GSM-capable wireless security camera systems is anticipated to increase over the following periods as more and more folks continuity to avail of mobile GSM connectivity for almost all of their personal and business applications.

* 3G video security cameras

GSM-capable wireless security cameras are even made better with the appearance of 3G connectivity. These cameras require no web connection to send photographs and video footages as they can use the 3G network to send this info right to your mobile telephones and other handheld widgets. More and more mobile users make use of 3G networks with the emergence of smart telephones and similar devices. It would just be logical for wireless camera networks to also employ these popular 3G networks to send pictures and video information.

I see some of their phones now use GSM on their website… Anyone know for sure?

no, verizon is still using CDMA and the phones that have GSM are dual CDMA and GSM compatible, so if you take it internationally you can use it.

Know More About Wireless Outdoor Speakers

One of the great impediments to a great outdoors experience whether it be at the pool or at a camp site was the fact that most music gadgets that people carried were old fashioned; not only requiring batteries but also if it was a sound system the speakers were attached to the actual musical device. This meant that the quality of music was somewhat compromised due to the wiring involved between the speakers and the actual unit. But technology has since advanced and this scenario need not be the case all the time especially for those in love with the great outdoors. Wireless outdoors speakers are here and those that want to carry their IPods to the pool or a picnic or an outdoors camping expedition can now do so with quality acoustic mini speakers to enrich their musical experience. But first of all, let us see the concept behind wireless outdoor speakers.

Wireless speakers are powered by the same technological concept that works in radios. When music is being played, a device inside the speakers picks up the wireless signal and converts them to digital signals and then transmits them to the speakers. A digital amplifier inside the speakers decodes the signal and this comes out as sound. This essentially means that the signal is sent as analog but is transmitted as digital by the digital decoder inside the speaker system. This translates to very quality sound.

The range of wireless speakers can be said to be the same range that one would receive with a good cordless phone. This can be about 900MHz. One plus about wireless speakers is that the signal can transmit through walls making it convenient for users. No cables are needed to connect between the speakers and the tuner/receiver. The speakers also come with a tuner knob which can be used to tune the signal to the best frequency.

Wireless speakers are very convenient. They can be placed in any direction to the discretion of the listener and can transmit sound in any direction. This can be ideal for a group setting and the speakers can be placed out of the way where they will not hinder social activity.

Wireless speakers have become especially popular with outdoor recreational activities. This is because rather than each person coming with their own musical device, the whole group can listen to the same speakers which can be conveniently placed out of sight.

One downside to wireless speakers is that even though the name suggests they are wireless, they do require an electrical cord that runs from the speakers to the wall outlet. Another downside is that the speakers, although elegant, cannot guarantee quality sound past a certain distance from the tuner. This is because the signal gets weaker with distance. The signal being decoded can also experience interference especially if there are other wireless devices in the vicinity such as cell phones and other Bluetooth devices.

Distributed Antenna Systems for Indoor Cellular Network

Some 70 – 80% of mobile traffic originates from inside buildings. This is especially true in urban environments where the focus of the mobile user is on high data rates. For mobile 3G network, only serving macro base station within a few hundred meters of the building can provide sufficient level of RF signal to support indoor voice/data services. In realty, only a few buildings will fall into this category. Soft handover in 3G network will further increase the traffic load on the network since each indoor mobile phone can be serviced by more than one macro cells (base stations). In order to provide indoor high speed mobile data services such as HSPA (High speed Packet Access) or EVDO (Evolution – Data Optimized) services, the only solution is an indoor Distributed Antenna Systems (DAS).

DAS is used to distribute the RF signal evenly with sufficient strength inside a building to provide 3G voice and data services. DAS can be used to isolate the indoor network from the outdoor serving macro cells to eliminate the soft handover of the indoor mobile phone. This will reduce the traffic load and increase the speed of the 3G network. For HSPA high speed data service, indoor DAS can also provide isolation between serving and non-serving cells of the outdoor network. This means less co-channel interference in the HSPA serving cell and results in higher data rate for the HSPA service. To dominate the building with indoor coverage, directional antennas can be deployed at the edge and corners of the building and pointing towards the center of the building. The total indoor area is dominated by the indoor cell and at the same time minimizes leakage to the macro network.

DAS distributes a uniform dominant RF signal inside the building by splitting the signal from the indoor base station to multiple indoor antennas to provide coverage throughout the building. DAS can be classified as passive or active. Passive DAS uses passive components to distribute the RF signal. These passive components are coax cable, splitters, terminators, attenuators, circulators, couplers and filters (duplexer, diplexer or triplexer). Planning DAS includes calculating the maximum loss from base station to each antenna in the systems and does the link budget for the particular area that each antenna covers. The passive DAS design needs to adapt to the limitation of the building regarding the restriction to where and how the heavy coax cable can be installed. A detail site survey of the building needed to be done to make sure that there are cable routes to all antennas.

Active DAS has the ability to automatically compensate for the losses of the cables interconnecting the components in the system by using internal calibrating signals and amplifiers. It does not matter what the distance between the antenna and the base station, all antennas in an active DAS will have the same performance (same noise figure and downlink power). Active DAS consists of a master unit (MU) connected to multiple expansion units (EU) with optical fiber up to 6 km in length. Each EU in turns connects to multiple remote units (RU) with thin coax or CAT5 cable up to 400m in length. The MU controls and monitors the performance of the DAS. The EUs are distributed throughout the building and the RUs are installed close to the antenna. A wideband active DAS can support multiple radio services, GSM, PCS, UMTS, EVDO, WiMax and WiFi.

Due to the loss and attenuation in the coax cable and passive components, passive DAS is only used in smaller building covers by a small number of indoor antennas to keep its degrading impact on HSPA performance to a minimum. For larger building, active DAS is used because it does not have cable and component loss and can boost the HSPA performance to the maximum. Troubleshoot in passive DAS is difficult and any fault in the systems will not raise an alarm at the base station because there is no surveillance of errors in the system. Active DAS monitors all units in the system and in the event of malfunction; it will send an alarm to the base station which enables the operator to pinpoint the source of the problem. Hence, active DAS is the preferred solution for large building with a lot of indoor antennas.

Using security camera system in Food Restaurants

Food restaurants are the busy places where customers come and go. The number of people traveling in and out constantly, and in such an arena, the fast pace of the events take place present various problems for security staff. For that purpose, it is a need to use the something new in technology to help protect customers and staff and network security camera system from a good security provider like Wireguys, represent  something new in that technology.

Wireguys types of providers gives you the best security monitoring systems and provides the security through wireless security camera, wireless cctv camera, cctv camera system, wireless cctv, security monitoring systems, Phone Wiring Toronto

Benefits of Network security camera system  

Network cameras use a network like a LAN system or the internet, to store recorded video data. While old CCTV analog style surveillance cameras might save to tape system or a VCR, a network camera can save to a remote or local PC. Of course, this will save big amount of space and money.

Another benefit of network wireless security camera is that the ease of which recorded footage can be viewed and transferred. Copies can be made for a crime purpose and can be sent to the police and security personnel, to increase the possibility that perpetrators will be caught and identified. The differences between a tape that needs a VCR to watch and a digital file that can be viewed on a television, computer or even mobile phone should be obvious.

Challenges in Food Restaurants

Food restaurants present many challenges to security personnel looking to keep the place monitored effectively. Many people constantly traveling in and out and also a large amount of money constantly changing hands, make watching out for criminal activity that a bit more tough, as well as making a fast food restaurant an luring option for a criminal looking to steal some easy money.

Placing a Network Camera

If you are placing a network wireless security camera in a food restaurant, it is very important to seriously think about camera placement. But make sure the entrances and exits of people to the location are all covered and the cameras are positioned well so that all entering and exiting are recorded on video. Also cover all areas, as this is where hold-ups will take place. There will also be a safe in a back room where money of the day is kept and it would be a good idea to have this covered with its own camera also.

So, using security cameras in restaurants are very necessary.

Since Alexander Graham Bell invented the telephone in 1872, it has been widely used by people for calling. The invention of the radio by Guglielmo Marconi, known as wireless telegraphy, has paved the way for birth of mobile communication, which used handheld talking radios known as “walkie talkies”. These devices have been effective since their use on World War II, although the frequency limits the communication distance connecting them, in comparison to telephones. Later, the cordless phone was invented to provide people the convenience of calling people anywhere around their homes.

That’s just on the oral communication side, the written side of communication has innovated since people created drawings during prehistoric times. Alphabets came to existence as part of languages people speak since the Sumerian civilization, which led to the concept of sending and receiving written messages. Before telephones and radios were invented, people write letters and send them to their recipients through the use of postal service. It was not long until computers and Internet came to existence within the 1980s, resulting to the use of electronic mail (email) that sends and receives messages conveniently without the costly reliance on various modes of delivery.

Combining the history of both oral and written communication, SMS or short message service emerged since its first application to mobile phones in December 1982. After its debut, the number of SMS active users has grown to 2.4 billion, which makes up 74% of all mobile phone consumers. In fact, SMS has been widely used by advertisers to endorse their products and services due to the rising number of cell phone users. Due to its reliability to various consumers, 4.1 trillion text messages were sent as of 2008, making SMS text messaging service a large-scale industry, with its value worth more than $81,000,000,000 worldwide as of 2006.

Everyone who has experience on using mobile phones knows what SMS does. For those who don’t, SMS is simply defined as sending text messages and its one of the widely used functions of the mobile phone other than calling. It became part of the Global System for Mobile Communications (GSM) in 1985, wherein its technical definition is about sending a message consisting of a maximum of 160 characters. SMS users also changed the concept of using languages in order to hasten the communication process and to conveniently send short messages better at a limited space. For example, the English word “you” becomes “u”, since both the word and the letter are pronounced similarly. The shortcut words, like “u” and “y”, are also being used as part of Internet slang.

SMS works in a technical process, wherein the messages are delivered to a Short Message Service Center, which applies the “store and forward” method. It involves storing the message in a temporary location before being delivered to its last destination, which is the recipient of the text message. As mentioned earlier the maximum characters to be typed in an SMS message is 160, which includes letters, numbers, symbols, and spaces. Messages with higher content can be sent through the use of several messages, wherein each one is initiated with a user data header (UDH) that has segmentation information.

That’s how SMS is understood in terms of history, definition, and process. You may wonder yourself which function is cooler to use, calling or SMS. What matters the most is that SMS has changed the modern society that it has taken communication all the way to the next level.

The owner of my apartment has asked the permission to install a device contains 16 mobiles at once?!?

Well, I’m not concerned with the purpose of this device or what is it for, but the thing is how that could be harmful to me, probably not all mobiles in that device are transmitting at the same, time I’m not sure! but it could happen, is that of any danger.

It’s 2 watts total, less than a cell phone, so there should be no concerns.
