Technical Specifications:
On the previous three pages, we talked about the packaging and contents of each system aswell as listed the technical specifications of each camera. Here, we are going to briefly go over each of these specifications and describe how each camera differs from one another.
The main thing that you look for in a camera is its ability to take video and transmit that to the receiver. Its ability to do this is greatly dependent on the processing power of the camera itself. All three of the WiLife cameras come standard with a 400 MHz DSP processor. DSP stands for Digital Signal Processing, which has now become a standard for most digital cameras. The speed of 400MHz may not sound like alot when talking about processor power today, but 400MHz is plenty enough for its purpose. The 400MHz DSP processor takes the video it recieves and encodes it as a Windows Media Video 9 file.
The cameras also record in either VGA (640x480) or QVGA (320x240) resolutions. The 640x480 resolution may be considered small, but it is large enough to see everything that is going on at any given time.
They can also record at 5, 10, or 15 frames per seconds. This would have to be one of the major downfalls of the system, max record at 15 frames per seconds. Viewing a video at 15 frames per second is a little choppy, but if there is no fast motion you can make out what is going on. But in the case of someone running by or any fast motion the video will be blurry and rather laggy.
The last configurable setting that you can choose is the bit rate. The bit rate is able to be configured at either 400, 600, or 800 kilobits per second.
All of the WiLife cameras have upto 16 programmable motion detection zones. These can be used if you have a tree that keeps blowing in the wind that triggers the motion detection. Its a simple selection of where you want the camera to detect movement. Also the cameras come with adjustable brightness and contrast settings to manuall configure the proper amount of light but incase you dont want to mess around with that, there is an auto brightness setting that will automatically change the brightness. This is a great feature when using an outdoor camera as there are different amounts of sun light throughout the period of a day.
Looking at the Lens on the cameras, we notice that each lens has a diagonaly viewing angle of 80 degrees. Although the indoor camera is able to swivel around gaining an additonal 50 degrees. Both the outdoor camera and spy camera have a preset focus, which you are unable to change, whereas the indoor camera has a focusable lens. Also all cameras have the availability to be update manually or automatically.
