Vehicle video recorder

User manual

In december 2011 I bought a vehicle video recoder from SuntekStore. On their site, the product is called "Vehicle Sport Car Mini DVR 2.5 Inch TFT Screen Camera with HDMI" but in the documentation its called "HD720P Portable DVR Road Safety Guard". In this user manual I will refer to it as a vehicle video recorder. The Suntek reference is 14001692.

I chose this video recorder for its wide angle, 140 degree "fisheye" lens.

The instructions included with the product are in chinese characters with an english language translation which supposes that the user already understands the product. This page proposes a simple "User's manual" which includes the original instructions and further notes based on my experience.

There is also a french translation.

The vehicle video recorder has a video recording capacity of at least 6 hours using a 16 Gbyte SDHC card. The wide angle lens and the considerable compression of the MJPEG encoding produce some image and geometric deformation which are not a problem for a vehicle video recorder but which would not be acceptable if you are looking for high quality video.

If you need high quality video, choose a less specialised product.

2 — The accessories

2.1 — SD or SDHC card

The vehicle video recorder requires an SD/MMC or an SDHC card such as the one shown on the left. This card is not supplied with the product. You have to buy one separately.

The vehicle video recorder operates correctly with a class 10 SDHC card, that is, a card able to perform sequential writes at at least 10 Mbyte/sec. I do not know if it will operate correctly with class 2, 2 Mbyte/sec, class 4, 4 Mbyte/sec ou class 6, 6 Mbyte/sec cards. You will have to experiment to find out.

A 16Gbyte card makes it possible to record 6 hours of video at the maximum resolution of 30 images per second with a 1280×720 pixel image size.

3 — Operation

There are two ways of starting and stopping the camera: manually and automatically. In normal operation the vehicle video recorder starts and stops automatically, however this can also be done manually.

3.1 — Automatic start and stop

If the vehicle video recorder is connected to a 12V socket, the camera starts operation automatically when the car starts. The red indicator [2] lights up because the internal battery is being charged. Note that the vehicle video recorder will start operation if you simply turn the car's ignition contact key without starting the engine. The camera will continue to record until you turn off the motor and the recording period ends. The is the normal operating procedure.

When you turn off the ignition, the vehicle video recorder will continue recording until the current recording period ends, and then the camera will automatically stop.

3.2 — Manual start and stop

If you press on the [ON/OFF] button, the vehicle video recorder will begin operating using its internal battery. This is useful for setting up the configuration options. During this time, the power on and battery charge indicator [2] will show a green light.

If you press again on the [ON/OFF] button, the vehicle video recorder will stop operating.

3.3 — Charging the battery

The vehicle video recorder recharges its internal battery if it is connected to a 12V socket, or to a powered USB socket. During the battery recharge, the battery charge indicator [2] show a red light.

4 — Video recording mode

When you turn on the vehicle video recorder it automatically enters video recording mode. The files created are saved on the SD/SDHC card.

The recording will stop when the camera is turned off or when you press on the [REC/SNAP] button.

5 — "Photo" mode

The vehicle video recorder can be used to take photographs. In this case it is common to detach the camera from the suction cap and to remove the power cable. To enter "photo" mode press [ON/OFF] to start the camera, and then press [MODE] to enter "photo" mode. A small icon representing a camera appears in the top right hand corner of the screen.

Once you are in "photo" mode, press [REC/SNAP] to take a photograph.

6 — Playback mode

Figure 5 — The playback screen
The playback screen

The vehicle video recorder can also play back photos and videos from the SD/SDHC memory. This playback function may be useful while travelling, it is ofter easier to manipulate the files either by the connecting the camera to a computer using the USB cord, or by removing the SD/SDHC card from the camera and placing it directly in a computer.

To enter playback mode, press [ON/OFF] to start the camera, and then press twice on [MODE] to enter playback mode.

To select the file to be viewed press on [UP] and [DOWN] to find the directory and then on [REC/SNAP] to enter the directory,

If the file is a video, You can view it by pressing [REC/SNAP]. The video is identified by the date mm/dd/yyyy and the time hh:mm:ss included in the video. For example you can see 12/28/2011 10:38:42 in the screen capture. The "0210" in the image means that the file is found at the address DCIM → 100DSCIM → REC_0210.AVI in the SD/SDHC memory.

If you view a photo, the identification number, for example 0214, means that the photo is at the address DCIM → 100DSCIM → JPEG0214.JPG  on the SD/SDHC card.

6.1 — Deleting a recording

Figure 7 — Confirm the delete

To delete a video that you have selected, press [MENU] to enter delete mode. You will see the sub-menu shown in figure 6. Use buttons [UP] and [DOWN] to move within the sub-menu, and then press [REC] to indicate your choice. You will see the confirmation request shown in figure 7. Press [REC] to confirm your choice.

To reformat the SD/SDHC card, choose the option FORMAT and then press [REC] to confirm the reformat. Warning: It is very easy to end up reformatting the SD/SDHC card when all that you wanted was to delete a recording. The reason is that in the deletion sub-menu of figure 6 it is not clear which of the two fields has been chosen. the grey field?, or the clear field? If you think it's the clear field then you are mistaken. because the chosen field is greyed. How many times has the SD/SDHC card been reformatted in error because of this ambiguity?

To leave the delete sub-menu press [MENU] to return to playback mode.

Use buttons [UP] and [DOWN] to chose between "On" to record sound and "Off" to stop recoding. Press [REC/SNAP] to confirm your choice and leave the sub-menu.

7.3 — MotionDetect — Record only if motion detected

The vehicle video recorder contains an image motion detector. If the detector is turned on, the camera will begin a new recording period only if there is movement in the image. Once the recording period begins, it will be completed, but the following recording period will only begin when, once again, motion is detected.

Use buttons [UP] and [DOWN] to choose between "On" to turn on the motion detection, and "Off" to not use this facility. Press [REC/SNAP] to confirm your choice and leave the sub-menu.

7.4 — FPS — How many images per second?

The vehicle video recorder creates AVI container files which contain video in the MJPEG format, which is a sequence of independent JPEG images.

Use buttons [UP] and [DOWN] to choose between "10FPS" for 10 images per second, "20FPS" for 20 images per second, and "30FPS" for 30 images per second. Press [REC/SNAP] to confirm your choice and leave the sub-menu.

7.5 — RecordTime — Length of each video

The vehicle video recorder records a sequence of short videos. You may choose the length of these videos. When the SD/SDHC card is full of these videos, the oldest one will be removed to make room for the latest. This operation takes between 1 and 5 seconds during which time there is no recording. If you choose the HD format at 30 images per second, and a video length of 5 minutes, a full 16Gbyte SD/SDHC card will contain 72 files, which is 6 hours of video.

Use buttons [UP] and [DOWN] to choose between 2, 5 and 15 minutes of video in each file. Press [REC/SNAP] to confirm your choice and leave the sub-menu.

8 — USB mode

If you plug the vehicle video recorder into your computer using the USB cable supplied, the product will automatically turn itself on and begin charging its internal battery. The vehicle video recorder will show the well known "USB" logo that you see here on the right.

The Windows operating system will present the vehicle video recorder in a window as removable storage (E:). The files containing the recordings are in directory DCIM → 100DSCIM . The videos have names such as REC_0210.AVI and photos have names such as JPEG0214.JPG .

To view the video files I use the excellent VLC software, but other software is capable of presenting the AVI/MJPEG format.

NB : The description of the USB mode given in the english language instructions that came with my vehicle video recorder seem to be incorrect.

9 — HD TV Playback

Plug the vehicle video recorder into a television set or other "HD" equipment, and the vehicle video recorder automaticcally enters TV playback mode. See the instructions in chapter 6.

Note: The HDMI cable is not supplied. Its up to you to find one.

10 — Technical specification

10.1 — Re-initialising the vehicle video recorder

Here is some advice which can be very helpful. The vehicle video recorder behaves as a computer. If it "crashes", you can reset it by pressing gently in the [RESET] hole with a pin less than 1 mm thick. millimètre.

11 — A problem?

Some personal experience:

  1. The camera unexpectedly turns itself on while being handled.

    It is very easy to accidentally press the ON/OFF [6] button on the side of the camera. It is preferable to hold the camera by the top and bottom rather than by the sides.

  2. After a few day's use the suction cap drops off the windshield.

    You can get a more permanent vibration-proof attachement by spreading a few drops of thread locker liquid on the suction cap. It is still possible to remove the camera from the windshield. On the right you see the product I use. It's probably useful to protect the suction cap from the harmful effect of sunshine.

  3. It is not possible to attach the camera to a vertical windshield with the camera horizontal.

    Remove the suction cap from the camera and re-attach it with the suction cap lever vertically above the camera while the camera's attachment screw is vertically below as shown in figure 10. To do this, remove the flexible cap. You will find, hidden behind the cap, the screw which allows you to make the necessary adjustment.

  4. Whilst in video playback mode, you request that one single file should be erased, but the camera reformats the SD/SDHC card and all the files are lost.

    The cause is a confusion between the black, grey and clear zones in the file erasure menu. See a detailed discussion of the problem.

  5. The vehicle video recorder doesn't record any video.

    There is no SD/SDHC card in the camera.
