Blackbox DVR/Dashcam

[oj88]

@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.

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.

Ako dinidisconnect ko yung connector ng GPS everytime I park. Kaya namang sungkitin ng daliri ko hehe. Mas hassle kasi pag naubusan ng batt yung DVR, narereset yung time and date. Set up na naman kada bukas ng DVR.

I want the most elegant solution kasi. Call me maarte..

I'd want the GPS module to power up and down with the DVR, not the ignition key. So I can still move it temporarily to another car with the GPS module intact and fully functional, running off the DVR battery. Kaya it's taking me a while to think it through.

^I feel you hehe. Kaso ako medyo mahina sa DIY lalo sa electronics.

Are there other alternatives other than the ones posted here and CD-R King?

[crazy_boy]

i also bought one here in Taiwan.

Full HD na. a bit more expensive than the x3000

CB , ang linaw ng kuha kahit gabi. magkano yung ganito
