Video systems have become part of our daily lives. When the video surveillance system was in the market in the mid-eighty year, it had a significant impact on the instant offense and in which the investigation was to prevent the crime. Early video systems require a physical connection between the cameras and the recording system. Modern innovations in the wireless best video camera broadcasting change this requirement
Wireless video systems are everywhere to meet many customer needs. Wireless video systems are available in a wide range of prices, features, and functions, from wireless child radio to high-definition wireless transmission systems.
Most modern user-level wireless video systems are compatible with one of this freeware: 900 MHz, 2.4 GHz or 5.8 GHz All low-power wireless cameras are in the market within approximately 2.4 GHz.
Each wireless video system includes a camera, transmitter, receiver, antenna, and power supply. Transmission times can vary significantly based on frequency, antenna, and minimal power.
Except for high-power transmission quality systems, most wireless video systems do not require a license from the Federal Communications Commission (FCC) to work. No matter how many times you plan to use, especially if you’re installing airport-roads or near-near-high-energy installation, you should get the appropriate FCC license.
For better results and more extended access, most wireless video transmission systems require continuous space between transmitters and receivers that do not work effectively through wireless video signaling glasses, walls, concrete, trees, steel or other barriers.
Also, the other RF signals around the same propel may cause interference or interference with wireless video systems. 2.4 GHz, in the range of famous in all security applications, wireless phones or microwave ovens or local TVs. Or may interfere between computer or power source or LAN / WAN network, wireless screen program. Interference problems can sometimes be solved by rediscovering transfers or receivers.
Because 90% of consumer wireless video systems are in the 2.4 GHz class, we will consider the features and limitations of analog and digital 2.4 GHz systems.
All 2.4 GHz consumers specified to use 2.462 Megahertz.ofaqa standard FCC to 2,412 MHz, thereby 11 possible channel widths are 22 MHz with a distance of 5 MHz between each bar.
To enable many cameras on the same system, such viral children need genetic analog video home at 2.4 GHz, non-overlap frequency to reduce the monitor or front camera, fixed channel and interference.
These wireless camera analogs offer far less professional security, but these cameras provide 2.4 GHz, consumers and some of the most popular for end users of video surveillance systems.
Best of all, the professional security establishment understands 2.4 GHz video systems as reliable, low-cost housing solutions. 2.4GHz analog cameras are easily set by price, which is usually $ 69.00 to $ 140.00 per camera.
If you take advantage of digitizing, there are many limitations for sending analog video 2.4 GHz, which includes:
In the 2.4 GHz band, only four channels are available without interference. It limits these systems to a total of 4 cameras, and each group is kept for a separate pre-set frequency. Both of these stable frequencies are capable of transmitting 11 Mbps data (Mbps).
Because the analog 2.4 GHz wireless video transistor is on a constant frequency, they are subject to intervention from external sources. The average transmission frequency of the 2.4 GHz analog video link is approximately 200 to 300 feet when installed on a clear line from the website. The relatively low transmission distance becomes much less when introduced inside, usually with a standard projected system of 10 to 30 feet.
