'''Teltonika DualCam''' solution is perfect for capturing videos or pictures of the events that might occur on the road, e.g. crash. Mounted on the vehicle front window, two cameras are used, front and rear, to record videos before and after the events, take photos periodically or by request and send all data to the server.

===Periodic image sending scenario===
 
−
Periodic image sending triggers photo capture from a front camera, whenever the timeout is reached (sending interval parameter). If a camera has not finished uploading picture to a server, then the photo capture is skipped.

==Additional information==
−
===Video sending by trigger===
 
−
Video sending by trigger scenario monitors the selected trigger (video sending trigger parameter) and captures video before and after the event (video duration before trigger and video duration after trigger parameters). If the previously captured video has not finished downloading, then a new video capture is skipped until the old one has been sent. When this scenario is triggered, high priority eventual record is generated with the value corresponding to what triggered the scenario. See the table below.

==Camera ping transmission and TF status checking==
+
<youtube>https://www.youtube.com/watch?v=1ccD4Yo1zFA&ab_channel=TeltonikaTelematics</youtube><br><br>
−
Camera pinging was implemented to periodically check if a camera is connected to a device. This is done via “Get TF status” command for both front and rear camera every 20 seconds when ignition is on. The received result from this command is stored in two corresponding AVL elements “Front camera state” and “Rear camera state”. The following do not only store TF status, but also if response from the camera was received or not.

==Camera RTC synchronization==
+
[[Category:Video Solutions]]
−
Camera RTC synchronization is done anytime the device itself is synchronized (via NTP, NITZ or GNSS).
 
−
<br>
 
−
 
 
−
==Other camera related functionality==
 
−
Camera is configured if all of these conditions are met:
 
−
 
 
−
#'''RS232 mode is selected (DualCam)'''
 
−
#'''Camera was not configured since startup or one of the related parameters were changed (compression, framerate or OSD)'''
 
−
#'''Camera file transfer is not active'''
 
−
 
 
−
Active camera reconfiguration is accompanied by two consecutive camera shutter clicks.
 
−
If camera is disconnected and later reconnected, a device will detect it by periodic camera ping packet. Once camera is detected, the device will reissue the reconfiguration procedure.
 
−
<br>
 
−
===Camera file transfer reconnection===
 
−
If FMU1YX device has bad reception, server is not reachable or wrong server details are configured, then the device tries to open a link to a camera server few consecutive times. If no connection was possible to be established, then the connection is postponed for 30 minutes and tried again (or tried every configured sending interval if periodic image sending is enabled).
 
−
<br>
 
−
 
 
−
==DualCam camera file transfer support==
 
−
[[Image:CameraServerSettings.PNG|{{{general|size}}}|right]]
 
−
Once camera has at least one file captured, it starts connection to a remote server, which is configured by parameters “Domain” and “Port” found in the “Camera Settings” tab.
 
−
<br>
 
−
 
 
−
==Initialization packet==
 
−
On connection, a device sends an initialization packet.

'''Close a session command (CMD ID 0x0000)'''<br>
 
−
In case when a device connects to a server, but the server does not expect it to connect, server will respond by sending a CLOSE command after which the connection will be terminated. This command is also used when device connects to a server for a custom file sending and server finishes to send all custom files to the device.
