Q: What shall we do when the mainframe video input interface is
different from the camera input interface?
A: a 4-pin interface is used for the vehicle device. BNC interface
or air interface is used for the camera. If inconsistency is found,
please use an adapter or connect it to a standard line defined as
the line sequence for the vehicle device.
Q: What shall we do if recording is unavailable even when the
device is powered on and HDD is installed?
A: 1. Check that the HDD is formatted after HDD is installed and
HDD without formatting cannot be used. From the Main
Menu-Management Tool-Formatting, format the newly-installed HDD.
2. Check if the record channel is off or if timing record is set.
Recording is unavailable when it is not within the recording time
frame.
3. Check if the HDD is properly contacted, and the HDD on the front
panel is lit up.
Q: A record file is lost or no record file is found within a
certain period of time?
A: 1. Analyze to define the period of time between the final video
file is lost and the first video file is recovered.
2. Check if the device is power on within this period of time, for
example, delay record not set during mid-way shutdown or unloading
& loading.
Q: The vehicle PTZ cannot be controlled and cannot be rotated to
up, down, right and left?
A: Check if the protocol and baud rate of the PTZ are set
correctly, the address is consistent and if the channel video is
selected to be maximized when controlling the PTZ. For example,
when controlling the second channel, you shall maximize the image
in the second channel to control the PTZ.
