Q: What is the purpose of the tiny blue tag on the
A: The blue tag is actually the puller of removing the
screen protector from manufacturer.
Q: Does "loop recording" overwrite the last loop, or
does it just break it into segments?
A: The loop recording feature will overwrite the earliest
unlocked footage, but not break it into segments.
Q: How do I set up loop recording or normal
recording till card is not full? What are the benefits
or disadvantage of keeping motion detection on?
A: You can go to the settings page to activate the loop
recording function anytime. However, the default
setting is "ON" for loop recording function. Motion
detection will automatically pause recording while the
view is at rest (e.g. stopping at red light), so it can save
some memory card space by this function. However,
the disadvantage will be that the video may be cut into
many short ones, which may not be so convenient to
find the specific footage you want.
- 26 -
Q: The dash cam shows "card is full" and no more
A: I believe you have turned on the "G-sensor" function.
The G-sensor will detect concussion and lock the
corresponding video clip. A heavy door shut or driving
on a bumpy road may active the G-sensor, so the loop
recording function will not overwrite this locked footage.
Time by time, the memory card will get full even with
loop recording turned on. If you want to avoid this
situation, you can change the sensitivity level of
G-sensor in the settings or just turn off the "G-sensor"
high speed transmission of 1080P, a class 10 high
speed SD card is required and maximum card capacity
is up to 32GB. The larger card size will significantly
reduce the transmission speed and stability for the
dash cam, which is similar to computer hard disk.
Q: How can I save/lock a video manually?
A: You the press the
Emergency Lock button (facing
the screen, the third top on your right) to manually lock
the current video any time you want.
Q: What is max capacity of micro SD card that the
camera will accept?
A: The Sentry dash camera actually supports SD card up
to 32GB, but not 64GB. In order to ensure a stable
Q: It makes a rattling noise when operating, is this
item is defected?
A: Firstly we strongly recommend you stop using this SD
card in a computer until it is re-formatted. This issue is
usually caused by a failure of formatting the SD card.
To format the SD card will resolve this issue.
Q: The SD card was deleted in Mac OS X system, but
the dash cam still shows card full. Why is that?
A: When you use a MAC, you have to "empty the trash"
after you format the SD card. If you are using Disk
Utility to format the SD card in Mac as FAT32, please
use Master Boot Record instead of GUID Partition
- 27 -

Q: How do you make the camera record when the car
turns on and not stop until the car turns off? It
seems to go into standby if it doesn't sense
A: You just need to turn off the motion detection feature to
keep the dash camera recording when the car turns
10.2 For Sentry with Rear Camera
Does this product require a professional
installation or can I install it myself?
A: A professional installation is recommended but not
necessary, and it is actually not a very complicated
work. You can refer to Session 7.2 for more details.
Q: How is the rear camera connected to the main, and
does the main record both front and back
A: There is a built-in AV cable with the rear camera, which
is the connection cable to the main dash camera. And
yes, both of front and rear cameras can record
simultaneously, and their corresponding footages will
be stored separately in two individual folders in the SD
Just plug in the cable in the front cam, and it will work
Q: How do you switch to the rear camera?
A: In the default setting, the images from both the front
and rear cameras will be displayed on the screen. And
you always can click the UP button to switch the view
Q: Is the cord long enough for the Sentry with the rear
camera? How would you connect rear camera on
the inside?
A: The connection cord to the rear camera is
approximately 18ft long, which will fit the most of the
vehicles. There is a built-in AV cable with the rear cam.
