WiFi Hitting the Security Cameras Scene

Do you know what the latest development in wireless security cameras is?

The latest revolution in security cameras doesn’t involve the sensor or the lens, it involve the transmission signal.

Wireless security cameras are now going WiFi.

Looking at the latest technologies, it is no surprise that WiFi is welcomed in to this field. Many wireless surveillance cameras are now available to make any surveillance system highly efficient and functional.

A wireless security camera can perform many functions such as remote viewing, motion detection and recording, and the best of all is that it is battery operated.

To understand why wireless surveillance cameras have become so popular, you must first understand what WiFi stands for and its functions.

WiFi is short for wireless fidelity refers to a set of wireless networking technologies and more specifically referred to as any type of 802.11 network, 802.11b and 802.11a and dual band. The word WiFi was built by an organization named as WiFi alliance. A product that undergoes the WiFi alliance analyses is given the name WiFi certified.

WiFi is a wireless technology that handles the networking/communication between devices. WiFi is caused by Radio waves that are transmitted from an antenna and WiFi receivers pick them up. These signals are then broadcasted to the device with WiFi connection.

WiFi equipped consumer electronics range from automobiles, cameras, computers, camcorders, mobile phones, video games, GPS systems, DVD players, printers, and many more. Security cameras now have joined the growing list of WiFi devices. The reason is attributed to many homes now having WLAN (WiFi local area network). You would just have to connect the wireless security camera to the network to give coverage of wider areas.

In WiFi surveillance cameras, the video signals go over a wireless LAN and then to a video server or PC. You can install a WiFi surveillance camera much faster than a traditional wired security camera. Perhaps the biggest advantage is that the WiFi security camera can be remotely controlled by laptop or phone with Internet facility and the picture quality is uninterrupted. But the disadvantage lies in the security of the video transfer. If it is not encrypted, it can easily be tapped and create security problems.

How are WiFi surveillance cameras better than regular wireless RF security cameras?

RF wireless surveillance cameras use radio frequency wireless technology similar to some high-end cordless phones to transmit and receive wireless video signals. It has many advantages such as being mobile and can be set up anywhere. A major drawback of wireless RF security camera is that the radio signals used to transmit video can be interrupted by electric motored products such as AC, fluorescent lighting or cordless telephones which affect the picture quality.

Where should you use a WiFi surveillance camera?

A WiFi surveillance camera is made for indoor use, whether for a company or home use. It must be placed at locations with minimum RF interference.

What do resellers need to be wary of when listing WiFi surveillance cameras? As a seller of WiFi surveillance cameras, you must list the compatibility properties of these cameras with the different types of networks like 802.11b or 802.11g WiFi networks. This helps the customer make an informed decision and avoid unnecessary problems of refunds and returns. You become a trustworthy seller as opposed some sellers, who claim that the surveillance cameras are WiFi enabled but they use radio waves for wireless transmission and create network issues for the customer.

Is A Pocket Wi-Fi Right For You?

One of the latest innovations in internet technology today is the pocket Wi-Fi. Just like your regular modem at home, it connects to the internet wirelessly, but the only difference is that it’s a small, portable device that you can slip inside your pocket anytime. It also requires a SIM card that connects you to any tower of your telecommunications service provider in order to give you access to the internet. And just like your regular router, it allows you to access the internet using your smartphone, laptop, desktop computer, or tablet.

Advantages of Pocket Wi-Fi

The Wireless Fidelity (WiFi) 802 Dot 11 Wireless Standard

Increasingly, people are connecting to the Internet using wireless connectivity. Commonly known as WiFi, (Wireless Fidelity), the technology can be found in many laptops, netbooks, cell phones and a host of other electronic gadgetry. The technology, known as the 802.11 standard in industrial circles, works in much the same way as cell phone technology, though the range that radio waves are transmitted is considerably smaller.

802.11 is applied as the standard by the Institute of Electronic Engineers, (IEEE), where 802 defines the standard itself, and 11 the working group within the IEEE assigned the workload. After this, letters are applied to each release, which relates to a task group working on enhancements. There are four main standards.

Firstly there is the 802.11a standard. Whilst use of the 5GHz frequency does allow for relatively high communication speeds, it does limit the range of transmission. It is a popular choice for larger organizations, with transfer of data being as high as 54Mbps.

Secondly there is the 802.11b standard. This uses the 2.4GHz frequency, which broadcasts over a greater range. The compromise to this is with the speed of communication, which is reduced significantly to 11Mbps. It is very popular with smaller businesses, individuals and particularly coffee stores offering free WiFi.

Thirdly there is the 802.11g standard which also transmits using the 2.4GHz frequency. However, this standard allows speeds of 54Mbps to be reached, having been enhanced using all that is the best in the standards and improvements going before it.

Fourthly there is the 802.11n standard. Amazingly, this has been in discussion for seven years, was only ratified recently, and the full list of enhancements only published in October of 2009. However, many users have been enjoying the increased speeds and range offered since early 2007.

Whilst speeds of 600Mbps have been touted, this has yet to be experienced in real time. More common, is something around the 100Mbps mark, though many people see 160Mbps easily achievable. All this is provided on the lower 2.4GHz frequency; and thus provides a considerable range of data transmission too. The standard is also backwards compatible; thus upgrades can be done progressively to help with costs, and the technology is said to be future proof.

As advised above, these are the four most commonly accepted standards, and those which many are familiar with despite not having a particularly sound knowledge of all things IT. There are others of course that take up the other suffixes not otherwise mentioned.

Rather than provide different ways of connecting and providing higher speeds however, these are more technical modifications to how the WiFi network works.

All the speeds listed next to each standard is the highest possible speed advertised; though these are very much only to be expected in ideal conditions. The time of day that the network used is key to the speed achieved; relying very much on how many people are online, and what data is being transferred at any one time.

WiFi Antennas

The advancement in technology has enabled us to use a variety of gadgets, such as smartphones. Since these gadgets communicate wirelessly, the use of wireless antennas is on the rise. Whether at home or office, people find it more convenient to use devices that use WiFi antennas to communicate with each other.

WiFi antennas are better than traditional dipole antennas in more ways than one. The thing is that wireless antennas are capable of sending and receiving RF signals. Moreover, wireless networks work when radio transmission is sent through specific frequencies. Listening devices receive the transmitted signals. Some good examples of wireless devices are smartphones, laptops, and routers. These devices feature built-in radio signal receivers and senders. The antennas receive incoming RF signals radiating outgoing signals simultaneously.

Antennas found in routers can be mounted externally. However, other types of antennas are installed within the electronic devices. If you want to buy a WiFi antenna, you may want to keep a few things in mind.

Aesthetics

You can find these antennas in many different designs. Based on the design of your room, you can opt for an antenna of a specific design. The one you pick should suit your office or room.

Functionality

Different wireless antennas have different features. There are wide-band or multi-band designs. A more powerful antenna will be needed should you want a large area covered.

Omni-Directional

These powerful antennas can receive signals at 360 degrees. Typically, you can find these antennas in cell phones and WiFi routers.

Dipole or Directional

As the name implies, these antennas transmit signals in the direction they are pointed to. They have long range and can be an ideal choice if you live in an area that is far away from the place where you want to receive the signals from.

Yagi Antennas

For signal coverage from far away areas, we suggest that you go for yagi antennas. Let’s suppose you want to have WiFi available outside your house. One good option will be to install a yagi directional antenna.

These antennas work well for urban residents residing in quarters as they can save a lot of money. Rather than install multiple other antennas, a couple yagi antennas can do the job.

Cantenna

It’s a popular brand and refers to a do-it-yourself regular or directional antenna. You can use Cantenna antennas both indoors and outdoors.

Now is the time to upgrade your wireless antennas should you experience signal reception problem in your house. After analyzing the site, you may want to install a few more WiFi access points.

As soon as you have upgraded your WiFi antennas, you will notice that your device are working more efficiently. However, it is important to keep in mind that the role of antennas is to help with the concentration of signal. For a significant performance improvement, the radio transmitter has to be as powerful as possible. By keeping all these factors in mind, you can easily opt for the right WiFi antennas to meet your needs.
