Knowledge About Driving Recorder

Q1. What’s the necessary conditions for the selection of a good dash camera

  1. whether affixed to heat reflective film at the windshield and make sure the transmittance is good or not.
  2. Cigar charger location and length of the wire.
  3. Installation space and wiring.
  4. Using high-quality SD card(class 10

Q2. About Camera Installation Courses

  1. G-sensor
  2. GPS
  3. More than 100 degree viewing angle
  4. SD card output
  5. Automatically recording when car starts and automatically stop recording when engine stops.
  6. Night Vision ( IR LED)
  7. H.264 video compression format
  8. Continuous timing function
  9. Resolution more than 640*480

Q3. How about the dash camera resolution minimum requirements?

  1. Currently, the lowest resolution is 480P (640*480) 30FPS.
  2. 30 frames per second (NTSC) is minimum purchase standard, its advantage is low prices and variety.
  3. The disadvantage is not enough to use wide-angle feature. The pixels (480P is VGA).
  4. The higher the resolution, the better the video resolution, like a license plate on the front of the car can be recorded clearly. The disadvantage is that the price will be higher.

Q4. How to select wide-angle lens dash camera?

Wide-angle lens on the market has become the standard which most models built in. We advised consumers to choose more than 100 degrees wide-angle models in order to recording side of the image.

Q5. Does a dash camera need a monitor?

At present, consumer’s car is equipped with a small screen. Non display dash camera is designed for these customers. Using our video output cable connecting to screen and remote controller help you to change setting. They can be easily combined with existing equipment, economical and affordable.

Q6. Why dash camera becomes necessary?

Dash camera's greatest role, that is, from the road as you drive, there are pictures and videos as evidence, Before the dash camera launch at market. Both side will be dispute and even fight when the case occurred, with the dash camera, be able to use the backup video as evidence, to restore the site conditions, not only to reduce the chance of physical conflict, but also afterwards as a compromise, court evidence.

Q7. What’s feature about dash camera that has IR LED?

It’s have better night vision but poor viewing distance.

Q8. What is a loop video recording? Loop recording benefits?

When the memory card is full, it will automatically overwrite the oldest fragment of a record from the beginning of the video, another record mode is when the memory card is full but not in loop recording. The memory card is full will first warn. Loop recording has the advantage of avoiding immediate clear old data and make sure continue recording.

Q9. What is a dash camera without built-in lithium battery benefits?

Lithium Battery inside dash camera may be over-heat and be easy to be explosive. It is dangerous.
It’s a high-temperature environment inside a closed car, especially at summer; common lithium battery in a car will be easily get explosion. VACRON do not use lithium battery-powered, no burst of doubts.

Q10. Does car window heat-insulation sticker affect video quality?

Please select:

  1. Larger aperture such as F1.6
  2. High quality heat-insulation sticker

Q11. Resolution of 480P, 720P and 1080P?

480p: 640x480 Pixel
720p: 1280x720 Pixel

1080p:1920x1080 Pixel.

Q12. What is motion detector?

Recording automatically functions when moving objects go close to camera for keep records of wrong-behavior drivers

Q13. What is G-sensor?

Gravity sensor (G-sensor), commonly used in hard disk or CD Walkman, in the event of hard drive crash or need in a timely manner to stop the disc rotation. Similarly, Also through the car's airbag sensor operators to decide whether inflated. G-sensor installed on the Vehicle Video Recorders as collision sensors, if the vehicle suffered a strong impact, it will automatically perform "force recording." Mandatory video recording of the movie are different in general, will be saved in separate folders, will not be replicated overwritten, really black box vehicle! VACRON’s dash camera (all in one) whole configuration of G-sensor.

Q14. The difference between CMOS and CCD?

CMOS is widely used due to the fact that it contains the better specifications in signal transmission, heat-prevention and low electricity consumption and it is gradually applied to be the part used for high-end Mobile DVRs.
CCD:
Good in noise decreasing, but bad in power consumption.
CMOS:
Each pixel corresponds to an amplifier, and the signal is converted directly initially, it is more easy to be read. Defect: noise generated by large, but now this technology has been greatly improved.
Advantages: low voltage, power consumption is also less.

Q15. NTSC and PAL?

NTSC for North America, Canada, Mexico, and Japan.
Standard is 525TV line; scanning to be 4:3; resolution 720 x 480.
PAL standard is 25 frames per second image, Standard is 625TV line; separately scanning to be 4:3.
PAL for Germany, UK, Singapore, China, HK, Australia, and NZ.

Q16. What benefit for dual-camera at dash camera?

Configuration of two lenses, one must pull to the rear window, the rear being rear hit or when there is an accident, you can record the accident occurred behind the car.

Q17. What is interpolation technology?

Interpolate is a new technique in color simulation for low-resolution video file upgrading to high-resolution one.
Allows a lower pixel photos taken can simulate a higher pixel photos, this extra pixels is virtual, such as: the original 640 * 480
Expansion of 1280 * 960 resolution, if not common (ex.1280 * 960) It’s means have used the interpolation technique.

Q18. How much memory for dash camera requires at least?

This will be depending on the size and capacity of the memory card as well as recording pixel setting of devices. In general, the larger the memory, while the smaller pixel set, recording time can be extended.

Q19. How to confirm whether dash camera reach safety standard?

  1. Website checking.
  2. Manufacturer’s certification on the packing box.

Q20. What is H.264 video compression format?

H.264 video compression using the latest revolutionary technology, as long as the use of relatively small files, it allows you to see crisp, clear video screen.
H.264 on a wide range of applications can be reached unprecedented compression efficiency, such as video on demand, streaming and multimedia messaging.

H.264 provides excellent image quality in a wide range of operating range, as long as you need high-quality video, H.264 can be the use of ultra-low data rates, resulting in superior performance.

Q21. Does GPS necessary for dash camera?

If your dash camera has GPS, you can record the speed of the vehicle, running track, in order to check information easier.
