The Surveillance software is a ready-to-use appliance for the ''Argos®2D A100'' camera platform.

Customers may also extend the software according to their needs. The application source code is available under the BSD license (other licenses apply to third-party tools).

==Flash layout==
*SPI-NOR flash contains U-Boot boot loader and U-Boot environment
*Configuration data is stored to U-Boot environment (with Linux tool ''fw_setenv'' coming with U-Boot)
*NAND flash contains Linux kernel image (2nd partition, offset 16MiB, size 5MiB)
*NAND flash also contains root file system (3rd partition, offset 21MiB, max. size 256MiB)
*Root file system alternate partition (changed with each firmware update): 4th partition, offset 277MiB, max. size 256 MiB
*Root file system type is ''cramfs'', this is a read-only file system.
*Firmware update includes Linux kernel and Root file system, not U-Boot, nor U-Boot environment.

==Firmware update image format==
*ZIP file
**uImage (Linux kernel as built by LTIB)
**rootfs.cramfs (Root file system image as built by LTIB)
**version.txt (Text file, containing firmware version string, e.g. "1.0.0")

==Video stream==
*Created with GStreamer framework
*Threaded C application
*Pipeline overview
mfw_v4lsrc --> ismconv --> mfw_ipucsc --> clockoverlay --> videorate --> tee '''(1)'''--+-->'''(2)''' queue --> capsfilter --> videorate --> capsfilter --> mfw_vpuencoder --> multifilesink
|-->'''(3)''' queue --> mfw_vpuencoder --> capsfilter --> ffmux_mp4 --> filesink
'-->'''(4)''' queue --> mfw_vpuencoder --> capsfilter --> ffmux_mp4 --> filesink
*'''(1)''' Capture bin: Captures camera input, converts from Bayer to RGB, converts color space (with i.MX IPU), adds time/date overlay, harmonizes frame rate with ''videorate''
*'''(2)''' JPEG encoding bin: Decreases frame rate to 1/2 fps, encodes JPG image with i.MX VPU, writes to file (overwriting the old)
*'''(3)'''/'''(4)''' H.264 encoding bins: Encode to H.264 with i.MX VPU, muxes into MP4 with ffmpeg library, writes to file
*'''(3)''' and '''(4)''' are running alternately, with overlapping of 1 second

==Source build==
*You need to have the Bluetechnix i.MX53 Linux BSP installed. The version required is listed with each SurveillanceApp software release.
*In the Source package, following the instructions in the file
INSTALL.txt
