LavenderCAM.net Frequently Asked Questions

 
Why are the web pages / formatting out of alignment?

LavenderCAM.net has been optimized for Firefox 4 and IE9. I am unable to test any other web browsers. Although image streaming uses Java script, there are parts of the site that use Adobe Flash - some browsers may not support this.

Why is the refresh rate really slow?

In order to protect bandwidth and the viewing experience of other users (especially during busy periods) LavenderCAM.net employs dynamic bandwidth throttling to ensure most viewers see an image that is updated at least every 2 seconds.

Why can't I see a picture?

There may be many reasons for this. If you feel none of the following apply, please send us an email. (1) The image is updated using Java script. Please ensure your browser supports this. (2) There may be too many viewers - try again a little later. (3) The camera / server may be experiencing technical difficulties - do let me know so that I can attempt a reset. (4) You are trying to access the camera directly without going via the LavenderCAM.net home page - this is not allowed. (5) Your IP address has been banned due to possible abuse.

How does LavenderCAM.net work?

LavenderCAM.net runs on an Axis IP network camera uploading an image every 1 second to our web server. Your web browser views and updates this image using Java script.

What hardware does your weather station use?

The weather station runs on an Oregon Scientific WMR200 sending data to "Weather Display" software.

It is raining, why doesn't the weather station show rain?

The weather station's rain gauge works on a "tipping bucket" principle. The minimum amount of rain to cause the bucket to tip is 1mm.

How is cloud base calculated?

Cloud base is calculated on the principle that air cools at approximately 2°C per 1000ft (the standard environmental lapse rate). Taking into account this cooling per 1000ft, cloud base is approximately the height that the temperature reaches the dew point.
