Major Product Features
- There are 2 cameras embedded in the product and their lenses are located on the front end and back end of the unit as shown in the picture within the circle below.
- There are 3 plastic suction hooks for attaching the DVR to the windscreen or any other surface suitable for holding the DVR. The hinge connecting the hooks to the DVR is adjustable and this allows the cameras to be positioned as desired within limits. The DVR is quite light (about 140g), and the hooks are adequate to hold the DVR in position.
- There are 4 Infrared LED on the side of the DVR facing inward the car cabin and they are on the LHS of the camera. This set of Infrared LED is for night-mode operation when visible light is too low. The DVR will start up in night mode for the first 30 seconds, and determine if it should stay on night mode or day mode for subsequent operation.
- The DVR will record data onto a flash card (Micro SDHC Class 6 to be exact). Micro refers to its very small size, see picture. SD stands for Secure Digital which is a name given by the initial technology developer. HC stands for High Capacity. Class 6 means the card is capable of writing at 6MB per second.
- Compucon supplies one 8GB of flash card with the product. However, customers can use bigger capacity such as 16GB and 32GB which will support recording for a longer period (proportionally). We estimate that 8GB supports 8 hours of recording.
- The flash card should be inserted in the DVR unit as shown in the picture on the RHS before the DVR receives power. It is OK to change the flash card at any time as long as the DVR is not on power. Remove the flash card with recording and insert it in a Reader which has an USB connector. See picture on the LHS. Connect it to a PC and the PC will be able to display the recording on the screen. The Reader is supplied by Compucon as part of the product.
- The flash card contains the software needed to play the recording. The software will work under Windows XP, Vista or Windows 7. A separate CD with the software is supplied as part of the package for back up purpose.
- The DVR is powered by the cigarette lighter in the car at 5V. Such an adapter with cable for connecting the DVR to the cigarette lighter is included in the product package.
Operation of DVR
- The DVR will automatically operate once it has received power. Therefore always connect power only when you are sure the DVR should start operating. Disconnect power before attempting to remove the flash card out of the DVR or putting the DVR away.
Playback of Recording
- It is OK to copy the newly recorded file into a PC and save the file in the PC as the archive along with other files. As soon as the software is initiated, a full screen will be displayed and the 6 icons below at the bottom RHS corner are needed for display control.
