WiFi Hitting the Security Cameras Scene

The latest revolution in security cameras are not connected to the sensor or lens, causing the large signal.

Wireless security cameras are now going to WiFi.

As for the latest technology, it is not surprising that the WiFi is welcome in this area. Many wireless cameras are available for any surveillance system very efficient and functional.

Wireless security camera can perform many functions such as remote viewing, motion detection and recording, and best of all is that it is battery powered.

To understand why wireless security cameras have become so popular, you must first understand the meaning of WiFi and its functions.

Wi-Fi stands for Wireless Fidelity refers to the number of wireless network technologies, and more specifically referred to any 802.11 network, 802.11b and 802.11a, dual band. Word of the WiFi built the organization was named the WiFi Alliance. The product, which passes through the WiFi Alliance is analyzing the name Wi-Fi certified.

WiFi is a wireless technology that manages the network / communication between devices. WiFi is caused by radio waves transmitted from Wi-Fi antenna and receiver pick. These signals are distributed on the device with a WiFi connection.

WiFi range of consumers with automotive electronics, cameras, computers, camcorders, mobile phones, video games, GPS systems, DVD players, printers and more. Security cameras have joined the growing list of WiFi devices. The reason is attributed to many homes already have wireless LAN (local Wi-Fi). Just connect the security camera wireless network to ensure greater coverage area.

Wi-Fi cameras, videos to go beyond the WLAN, and then the video server or PC. You can install a WiFi monitoring camera much faster than a traditional camera wired safety. Perhaps the biggest advantage is that the Wi-Fi security camera can be controlled remotely from a laptop or phone to the Internet Department, and the image quality is uninterrupted. But the disadvantage lies in the transmission of video and data security. If not encrypted, it can easily be used to create security problems.

As Wi-Fi cameras are more effective than conventional radio frequency signals from security cameras?

Cameras use wireless RF radio frequency wireless technology similar to some high-end wireless phones transmit and receive video signals wirelessly. It has many advantages, such as mobile and can be implemented everywhere. A major disadvantage of RF wireless security camera is that the radio signals to transmit the video may be disrupted by electrical motors or fluorescent lamps AC cordless phones that affect the quality of the image.
