Wireless cameras have several different uses in the modern day and age. Among the most prevalent are for communication and for home security and surveillance. These cameras, also sometimes referred to as network cameras and IP cameras, are defined by their ability to send live video feeds via a wireless Internet network. They can be accessed from any remote web browser or mobile device.
Though all wireless cameras operate in the same basic way, they are not all created equally. Different cameras have different specifications that make them better suited for different applications. One of the most important specifications to take note of is that of Internet connectivity. Understanding this area of wireless cameras will allow you to select the absolute best one for you.
Wireless Network Standards
There are a number of different wireless network standards that wireless cameras can operate on. This basically refers to the transmission method that provides the Wi-Fi to a home or business. The most popular wireless network standards include the following.
Sometimes known as Wireless-N, 802.11n is one of the newest wireless local area network (WLAN) technologies. It is designed for use with with high-speed Internet. It is also developed to support applications that normally exhaust bandwidth, such s streaming video.
This type of wireless network standard, also known as Wireless-B and Wireless-G, is one of the most popular Wi-Fi standards. It was the standard that preceded Wireless-N. It might not be as fast or robust as a Wireless-N network but it still gets the job done. It is a great bet for those using wireless cameras for home security purposes.
It is also essential to understand security protocols when attempting to understand Internet connectivity specifications. These digital protocols are designed to utilize encryption methods to safeguard data. This means that they keep the images that you are transmitting safe during recordings and live feeds. There are several different types of security protocols that can be used for wireless cameras. They include the following.
WEP, or Wired Equivalent Privacy, is a security algorithm that is specifically used with 802.11 wireless networks. Though it was found to have several weaknesses when it was first released, especially related to eavesdropping, these have since been worked out of the system. It is not a solid security protocol for wireless Internet networks.
Standing for Wi-Fi Protected Access, WPA and WPA2 is one of the most commonplace security protocols around. Though it has mostly been replaced by WEP systems, it is still used in a number of different devices.
Another security protocol is TSL/SSL. This stands for Transport Layer Security/Secure Sockets Layer. These cryptographic protocols are designed to provide the highest level of security for Internet communications including email, instant messaging, and, of course, streaming video from wireless cameras.
