Download & Install
Install GUI to the device that will be used for recording. There are several ways to install it:
cd <any-path> git clone https://git.elphel.com/Elphel/eyesis4pi-393-gui.git git pull (repeat any time to get the latest)
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.
- Eyesis4Pi 393
- External SSD enclosure
- PC / Laptop
- Connect all cables - power, network, eSATA.
- Power on: switch, SSD enclosure, Eyesis4Pi393. Boot takes about 1 min.
- Setup PC IP (can be done beforehand).
- Refresh GUI after camera boots

Important Notice: Use a fan to cool the camera's pole when shooting indoors.
- Connect the PC to the Gigabit port of the switch.
- Configure the PC's network settings (Kubuntu Network Configuration Guide):

Setting recording parameters: camera settings
- Settings -> Camera-tab
Trigger period,ms - 1/FPS, 200 = 5fps, 250 = 4fps, 500 = 2fps, 1000 = 1fps... HDRVexpos - not used. Manual Exposure - used when auto exposure is off. AutoExp max, ms - the autoexposure value limit. AutoExp level - value of a pixel at which the autoexposure works. AutoExp fracpix - number of pixels below the Autoexp level. AutoExp frame ahead - number of previous frames used for calculatin the current frame exposure. HDR mode - not used Compression quality - JP4/JPEG compression quality.

Error 5 (frame buffer overflow)
- Frame buffer overflow counter ( = dropped frames).
- Possible causes:
- FPS and compression quality (combined) set too high: 5fps + 100%
- SSD write speed is slowed
- Errors are displayed as err5(N) against each buffer, where N is a cumulative number of errors
