When video guard systems first hit the shop in the mid 80's, they immediately made a major impact on crime stoppage and the way crimes are investigated. Early video systems required a hardwired connection in the middle of the camera and the recording system. Modern innovations in wireless video transmission are changing that requirement.

Wireless video systems are popping up all over the place to satisfy a range of consumer requirements. From wireless baby monitors to high-end high-definition wireless broadcast systems, wireless video systems are available in a wide range of prices, features and functions.
Longest Range Baby Monitor
Most modern, consumer grade wireless video systems will fall into one of the following frequencies; 900 Mhz, 2.4 Ghz or 5.8 Ghz. Roughly all of the affordable consumer grade wireless cameras on the shop fall into the 2.4 Ghz range.
Every wireless video theory consists of a camera, a transmitter, a receiver, an antenna and a power supply. Transmission ranges can vary greatly depending on the frequency, the antenna and the rated power output.
With the irregularity of higher end, high power broadcast ability systems; most wireless video systems do not need a license from the Federal communication Commission (Fcc) to operate. No matter what frequency you plan on using, if you are installing a high powered installation, especially near a highway or an airport, you should acquire the standard Fcc license.
For the best results and the longest range, most wireless video transmission systems need a clear line of site in the middle of the transmitter and the receiver to operate consistently. Wireless video signals do not jab very well through glass, walls, concrete, trees, steel or other obstructions.
In addition, other Rf signals colse to the same frequency can cause interference or be interfered with by wireless video systems. In the 2.4 Ghz range favorite with most security applications, interference can be experienced in the middle of cordless phones, microwave ovens, local television broadcasts, computer monitors, power supplies or wireless Lan/Wans. Sometimes interference problems can be solved by re-locating the transmitters or receivers.
Since 90% of consumer grade wireless video systems fall into the 2.4 Ghz category, we will discuss the features of both the 2.4 Ghz analog and digital systems and the limitations and benefits of each.
The entire 2.4 Ghz bandwidth allocated for consumer use is from 2,412 Mhz to 2,462 Mhz. As per the Fcc standards, there are 11 potential channels which are 22 Mhz wide with a 5 Mhz spacing interval in the middle of each.
In order to allow multiple cameras on the same system, residential, consumer grade 2.4 Ghz analog video transmitters such as a wireless baby monitor or a front door camera need fixed frequency, non-overlapping channels to sell out interference.
These 2.4 Ghz analog wireless cameras are some of the most favorite video guard systems for consumers and end users, yet very few pro security providers will offer these wireless cameras.
At best, pro security installers reconsider the 2.4 Ghz analog video systems as low-end residential solutions which are notoriously unreliable. The analog 2.4 Ghz cameras are really identified by their price tag which is regularly in the $ 69.00 to $ 140.00 range per camera.
If you take away the benefit of their low cost, there are any potential limitations to Analog 2.4 Ghz video transmission including:
In the 2.4 Ghz range, there are only 4 available non-overlapping channels. This limits these systems to a total of 4-cameras, each of which is tuned to a different pre-defined frequency. Each of these fixed frequencies is capable of transmitting about 11 mega-bits per second of data (Mbps).
Because the analog 2.4 Ghz wireless video transmitters are on fixed frequencies, they are especially susceptible to interference from surface sources. A typical transmission range for an analog 2.4 Ghz wireless video link is about 200 to 300 feet when installed outdoors with a clear line of site. The relative transmission distance is greatly reduced when installed indoors with some lower end analog systems typically providing about 10-30 feet.
Since these cameras are transmitted on a fixed, un-secured open frequency, the signal is really intercepted and can be seen by anything with a 2.4 Ghz 4-channel receiver. A voyeur or a burglar could simply drive colse to a neighborhood with a receiver and see inside your home. If you have one of these systems installed, maybe a burglar is watching you right now.
In 1997, the form of Electrical and Electronics Engineers (Ieee) created the first Wireless Local Area Network (Wlan) standard which was named 802.11. The former 802.11 utilized the 2.4 Ghz frequency to allow reliable transmission of 2-Mbps of bandwidth. In 1999, the standard was upgraded to 802.11b which supports up to 11 Mega-Bits per Second (Mbps) which was comparable to former Ethernet connectivity speeds.
The 802.11 protocol works by sub-dividing the entire 2.4 Ghz frequency into channels and switching in the middle of them while transmissions. As the signal is sent, it sends a packet of data at one frequency and then hops to the next channel and sends someone else packet and so on, until the entire data container is sent.
In 2003, Wlan products began supporting a new 2.4 Ghz wireless standard called 802.11g which supports a bandwidth of 108 Mbps of data. The days of cost effective, reliable and acquire wireless video transmission have ultimately arrived.
The added features and benefits of using internet protocol cameras and 802.11g for wireless video transmission in a security application are many.
The 802.11g protocol utilizes digital bi-directional signals which retain the use of pan/tilt/zoom functions and presets found in many newer cameras. The digital signal used is duplex (bi-directional) as opposed to the simplex (one-way) binary signal used in analog type systems.
Because 802.11g utilizes the entire 2.4 Ghz frequency spectrum, interference is greatly reduced and longer transmission ranges can be expected. If an area of the frequency is noisy then the transmitter/receivers will adapt the signal by sending smaller packets in the noisy affected area and larger packets in the non-effected areas of the frequency. A wireless Ip video theory will offer Roughly the same performance as a pro grade wired theory with a reliable transmission range of 150-200 feet.
If the camera is to be settled supplementary than 200 feet, directional antennas are available which can growth the distance to 600 or more feet. If a greater distance than 600 feet is required, point to point, long range directional type systems can growth the distance to any miles.
In expanding to standard 64/128-bit Wep Security, 802.11g protocol allows data packets to be encrypted using a 40-bit Rca key. When considered in conjunction with the potential security built into Dsss spread spectrum technology, the data signals are at least as acquire as data traveling over a wired network.
The 802.11g protocol can retain a much larger number of wireless cameras by using a medium entrance operate or Mac layer called Csma/Ca or Carrier Sense multiple Access/Collision Avoidance. The collision avoidance in 802.11g supports the use of Cts/Rts signals (clear to send/ready to send) which tell each camera on the theory when it is O.K. To begin transmitting or receiving data thereby avoiding interference.
Any hardwired Ip Camera that is installed on your intranet or internet that is using the same Codec (Coding & Decoding) algorithm can be integrated into the same software viewing and recording system.
An Ip addressable camera theory can be viewed or recorded from a properly equipped computer from any location in the world. This can allow you the freedom to move in any place on the planet while still keeping track of your assets. In addition, if you ever resolve to move your head end recording equipment to a different location, you simply pick it up and move it. No wires to re-route.
One thing to remember when deploying a multi-camera wireless Ip based video theory is that processing multiple streaming video signals places a mammoth work load on a computers Cpu.
Hard Wired systems have video capture cards which are installed in the Pc/Dvr. These cards take up to half of the work load off the computers Cpu. Because wireless Ip video systems do not have the help of these capture boards, the computers Cpu must handle 100% of the processing workload.
What this means is that as you add cameras to a wireless theory the total frame rate or the total images per second which can be viewed and recorded will decline due to the increased workload.
Some citizen shy away from Ip and network security solutions because they appear to be complicated and difficult to set up. The fact is the introductory set up does need some expertise and knowledge but the performance and day to day use of the systems are no different than using any other Pc based security camera system. The required computer skills are minimal. If a man can check email, use a word processing program or load and play any type of game on a Pc they most likely possess the skills needed to use and conduct a Pc based system.
