Download & Install
Install GUI to the device that will be used for recording. There are several ways to install it:

Follow the instructions in INSTALL.txt:
1. (For Kubuntu 16.04) Install the following packages, terminal: sudo apt-get install apache2 php5.6 php5.6-curl 2. Make the src folder visible to the web server: 2a. Create a link, terminal: "sudo ln -sf <path-to-eyesis4pi_gui-folder> /var/www/eyesisgui" 2b. Or copy all the files to /var/www/eyesisgui. Note: "/var/www" is the (apache2) web server's document root folder. (for recording to the device over network only) 2c. Make the footage root folder "/data/footage" writable for everyone.

- SSD write speed is slowed
- Errors are displayed as err5(N) against each buffer, where N is a cumulative number of errors
