2.4GHz Wireless Line-of-Sight Required
If you've been in an airport, coffee shop, library or hotel recently, chances are you've been right in the middle of a wireless network. Many people also use wireless networking, also called WiFi or 802.11 networking, to connect their computers at home, and an increasing number of cities use the technology to provide free or low-cost Internet access to residents.
The next evolutionary stage for 802.11 wireless is to utilize it for video. IP based cameras, unlike traditional analog cameras, can take advantage of pre-existing Wi-Fi networks to transmitt video wirelessly to the end user. Webcamproshop provides a complete Wi-Fi solution for environments without Wi-Fi enabled. For environments with pre-existing Wi-Fi, we also offer a solution that is compatible with stardard AP technology on the market. Unlike 900MHz, 2.4GHz requires "line of sight" from one point to the next. Each wireless link can have a range of up to 3 miles.
IP cameras on a 2.4GHz wireless link will approximately achieved 12-20 fps @ 320x240 resolution and 8-12fps @ 640x480 resolution. 1.3 to 5.0 Mega-pixel cameras can have varying rates of 1-5fps.
What if I don't have line of sight from point A to point B?
Line of sight is important when using 2.4GHz. It may still work, but is not recommended due to decrease signal strength. For non Line of Sight, we suggest going with a 900MHz link.
How come my 2.4GHz home wireless works with out line of sight?
With home wireless systems devices are within 100 feet of the base. Also most home wireless systems achieve a connection rate of 11-54Mbps. And it varies depending on the environment. Our Sidekick units are design for long distance, up to 3 miles, connections and therefore issues with Line of Sight can become problematic.
What do you consider Line of Sight?
Line of Sight is a 10ft radius of clearance from the point A to point B. Meaning no abstruction within that 10ft radius. It is suggested that binoculars are used to view Line of Sight for applications up to 3 miles.
How many cameras can one base station support?
This will depend on what your personal requirements is for each camera. Theoritically there is no limit, however we do suggest that no more than 5 camera stations per base station due to the fact that each camera station will be fighting for bandwidth. You might get frequent camera disconnections and reconnections when using more than the recommended. Our suggestions are for 320x240 resolution, you can achieve 5 cameras at approximately 10-20fps. For 640x480 resolution, you can achieve 3 cameras at approximately 8-12 fps. For Mega-pixel cameras, you can achieve 1-2 cameras at 1-5fps. Note that the more cameras that are on one base station, your fps will be reduced.
