I stayed at Castle In the Sand. Their WiFi network is more through than it was last year, but there are still some gaps in coverage. By sheer conicedence I stumbled across Ekahau Heatmaper. It’s a low tech solution to mapping out how much wifi signal there is in a given area and then project how much signal should be available in other locations nearby.
Shown above is the map of the hotel’s main WiFi SSID for the guests.
In order to use the wireless internet you have to get the settings from their website. Good job guys.
After some fiddling around with my new IP cameras I finally figured out why my videos would only be recognized if they were at the 320×240 resolution or lower. It turns out that a significant amount of memory is required for scanning and decompressing images (go figure). What I did not know is that the amount of allocated memory can only grow to a certain point before it hits the maximum amount for a given program. The ZoneMinder FAQ was very helpful in resolving the matter. Basically you issue a simple command to up the amount of memory allowed for each program:
echo 134217728 >/proc/sys/kernel/shmall
echo 134217728 >/proc/sys/kernel/shmmax
When I upgraded the main switch on the network in order to support multiple internet addressable web servers I noticed that whichever system I connected first could access the internet while the following ones couldn’t. I decided to call Cox’s support line to see what the proper procedure was for using multiple IP addresses. As it turns out the less-than-intelligent person who installed my modem did not set it up to use multiple IP addresses (nor did he know that I was receiving a business connection instead of a residential connection). The tech support agent figured the problem out and resolved the issue very quickly. I should have my secondary server up and running within a week.
