Blackbox DVR/Dashcam

*oj, meron bang option to disable the recording of the the rear cam?

iwas pusoy ke mrs. hahaha!

currently using cdrking DVR-017 (1.8k), not quiet happy with video at night...

Yes. Nasa menu if you want to record just Ch1 (front), Ch2 (rear) or both. You can also disable the audio/mic recording.

Manyak mode. :D

Opened up the GPS antenna.


it's not just an antenna but whole GPS module na pala.

Oj88,
Nagawa mo na ng paraan yung GPS battery issue? Yung akin kasi di ko na lang kinabit. I'm thinking of installing a switch to cut off the power when not in use or better yet a 5v normally open relay para automatic.

Yup. It's an active GPS receiver. It needs 5V power from the DVR and it sends back GPS coordinates using serial communications (ie. NMEA 0183 protocol). The memory backup battery is a dead giveaway. The memory serves to store ephemeris data and whatnot.

No I haven't tinkered with it. Like you, I also temporarily disconnected the GPS module.

I've thought of using a relay as well, one which can be triggered by the DVR's backlight circuitry or the power LED. The thing is, I'm not sure if the 3.7V LiIon/LiPoly battery will be enough to energize the 5V relay. In that regard, I think that a solid state approach is preferred (smaller package and lower power draw). I just haven't found the time to design the circuit yet.

But do tell if you make any developments.

My idea is simply to cut off a power wire from the DVR to the GPS module, connect it to a 5v triggered normally open relay and connect the relay power terminal to the 5v supply of the DVR (or a separate 5v USB car charger). so only whenever I the engine is running magkakaroon ng contact ang relay to supply power to the GPS.

Problem lang is I don't have a relay and ayaw kong pumunta ng Raon just to buy one.
