    :confused:Hi Guys, I've got a problem and hope someone can offer a solution, advice, or suggestion.

    Upon walking back to my car this afternoon, after performing an errand, I noticed the white Rear Security LED light on the rear camera was not lit. WTF! It should be lit, so I walked to the front of my car and observed that the white Front Security LED was On. OK. So what's wrong with the rear camera, I said to myself. I opened the passenger door, and reached in to make sure the Rear Camera Connection Cable was fully pushed in to the Rear Camera Connection Port on the front camera'a right side. It felt and looked like it was fully inserted into the port, but I pushed it a little harder to make sure. When I turned around and looked at the rear camera, the Rear Security Light was now On. When I got home I took out the microSD card to check some video clips, so I had to disconnect the cables. I verified the rear camera started recording after I pushed the Rear Camera Connection Cable in, when I was still at the store.

    After I reinserted the microSD card, and firmly and securely connected both cables to the front camera, the Rear Security LED light was not lit. No matter what I did to gently twist the Rear Cable in the port, take it out and reinsert it, a few times, I cannot get power to the rear camera.

    I seem to remember that I recently read a Post that someone had a problem with the "prong" that is inserted into the port on the front camera. I cannot recall what was written in the Post. I have searched, but I cannot locate that Post, to read it again.

    The "prong" appears and feels to be "solid and secure" on the end of the cable. I have looked into the port on the front camera where the Rear Camera Connection cable is inserted. I cannot see anything out of the ordinary.

    Before I take the car to an installer to troubleshoot the problem, I would like to try a few more things, but I don't know what else to do. Has anyone else experienced such a problem of not getting power to the rear camera. Or, does anyone have any advice or thoughts concerning the problem. Any suggestions would really be appreciated. TIA

    @DashcamAndrew, Do you have any thoughts, suggestions, or advice concerning the rear camera power problem?

    The rear camera cable uses a miniature version of a coaxial connector, with a single pin in center and the barrel acting as the ground. Make sure the pin isn't bent, and the "prongs" of the barrel aren't bent inward either. Check on both ends. If something is bent, you may be able to gently fix it with small needle nose pliers or tweezers. Otherwise, you may have to contact your distributor for a new cable.

    Also, you don't have to unplug the rear camera cable to change the SD card. Only the power connector has to be removed. The rear camera cable connectors aren't super sturdy, they aren't meant for repetitive connection and disconnection.

    Hi [MENTION=100]kpatz[/MENTION] ,

    Thank you for your response and advice. I have very carefully made sure that the pin on the end of the Rear Camera Connection Cable is straight, and I have also very carefully made sure the prongs of the barrel are not bent inward. I also made sure that the connection inside the camera, where the pin goes into, is straight and centered. I even made sure that the actual cable connection to the rear camera is secure. Still no power to the rear camera.

    Because the cable to the rear camera is tucked under the front headliner, as well as installed under other interior parts of the car as it runs to the rear camera, I do not want to uninstall it until I know for sure exactly what is causing the lack of power to the rear camera.

    So, I think I'll order a new Rear Camera Connection Cable. When I get it I will connect one end to the rear camera, the other end to the front camera, and see if the rear camera gets power. If it does get power with the new cable, I'll then remove the old cable and install the new cable.

    If the rear camera does not get power using the new cable, the power problem is being caused by something else, e.g. a bad port for the Rear Camera Connection Cable, or either the rear camera or the front camera has internal problems.

    I'll submit a follow-up Post as soon as I get a new Rear Camera Connection Cable and perform a test.

    Thanks again for your advice.

    Definitely agree with [MENTION=100]kpatz[/MENTION] to check the center conductor pin on both ends (at both front and rear cams) of the coaxial cable. Here's an image for reference, we do see sometimes the center pin is depressed like this and therefore not making contact.

    Also keep in mind the rear camera isn't hot-swappable, so the front camera needs to be turned off anytime the rear camera is going to be plugged in or unplugged. From my experience the rear cam will not come on after being plugged in to an already-on front camera.

    Good luck and if you're still having problems after verifying the pins are intact, let me know.

    Cheers,

    @DashcamAndrew

    Hi Andrew,

    Thank you very much for the information and your advice regarding the problem I am having in getting power to the rear camera of my Blackvue DR650GW-2CH system. I spoke with Gabriel yesterday evening, as I was going to order a new Rear Camera Connection Cable. He was very helpful in advising me to try some troubleshooting steps before actually ordering a new cable. I just finished trying the actions he suggested, but there is still no power going to the rear camera. I'll call him after I finish this Post and order a new Rear Camera Connection Cable.

    Let me mention some items regarding my 650 system, in case it may help you or anyone else in trying to diagnose the problem:

    1. My Blackvue DR650GW-2CH system was professionally installed in December 2015.
    2. The Rear Camera Connection Cable enters the headliner at the point where the rear view mirror is attached, above the front camera.
    3. The cable is then concealed under the headliner until it exits above the rear camera.
    4. The headliner, etc. will have to be removed prior to the old cable being removed and the new cable being installed.
    5. I will not do any of the headliner removal, I will have a pro installer perform that work.
    6. The entire cable is wrapped with tessa tape. As the main Power Cable and the Rear Cable exits above the front camera, the two cables are wrapped with tessa tape to within 1/2 inch of the cable ends that are inserted into the front and rear cameras.
    7. The rear camera and the Rear Camera Connection Cable have NOT been touched since December 2015.
    8. I followed Gabriel's suggestions of: formatting the microSD card, checked settings in the Blackvue Viewer configuration tool, had engine of car running to ensure sufficient power, inserted Rear Camera Connection Cable into front camera V port, inserted Power cable into the power power port. STILL NO POWER TO REAR CAMERA.
    9. I had previously checked the center wire on the end of the Rear Camera Connection Cable, to ensure, as best as I can, that the center wire is straight, and I checked it again today. Although the center wire appears very large in the pictures in your Post above, in reality they are extremely small, and even using a very bright flashlight, the wire is very difficult to see, as the cable protrudes only a couple of inches from the headliner above the front camera's position.
    10. I have also removed the front camera and, as best as I could, tried to see if the V port appeared normal or damaged. As best I can tell it appears OK, but I am not sure if it really is OK or if it is damaged.
    11. I will call Gabriel at The Dashcam Store and order a Rear Camera Connection Cable.
    12. When the cable arrives, I will connect it to the front camera, then drape the cable over the car seats and connect it to the rear camera, before any power is applied. If the rear camera gets power, I will have the pro installer remove the old damaged cable and install the new cable.
    13. If the rear camera does not get power after performing #12, I assume the V port in the front camera is damaged, and I also assume I will have to order a new front camera only, if possible, but I do not know if there are any DR650GW-2Ch front cameras available, as Blackvue is now manufacturing the DR650S-2CH system. I will have to speak with Gabriel or you, Andrew.

    As I mention in #13, If the front camera's V port is damaged, can the front camera be repaired? Or, should I just go ahead and order a new front camera? If only the Blackvue DR650S-2CH camera systems are available, should I order an entire "S" front and rear camera system, so that both front and rear cameras are the "S" series? (Is the rear camera for the 650GW-2CH system identical to the rear camera for the 650S-2CH system?)

    I must say that I have had no problems with two ALP Quint systems, no problems with two STiR Plus systems, that are installed in my cars. But I have spent sooo much time with the Blackvue DR650GW-2CH system, that if I could do it again, I would NOT ever get a 650 system again. I have spent over one year attempting to change the various configuration settings for the camera in attempting to alleviate the Pixelation problems that I, and numerous other 650 owners have experienced and write about. In my attempts to alleviate the Pixelation problems, I have removed and attached the Rear Camera Connection Cable to the front camera's V port numerous times. If that is where the problem is, the pin in the end of the cable that is inserted into the front camera's V port, it is a VERY WEAK COMPONENT of the system, and should be remanufactured in order to ensure that it will not be the cause of problems. I noticed, on the page for the Rear Camera Connection Cable, on The Dashcam Store website, that there have been numerous people who have ordered the replacement cable, and many people have written in the comments section, that the end of the cable with the pin no longer works, that the pin may be damaged due to its weak design, etc., etc.

    @kpatz Thank you very much for your input and advice!

    @wirelessandy Thank you very much for your input and review of the Blackvue 550, along with the problem with the center wire in the cable. Maybe that is what is causing the rear camera power problem I am having.

    I'll say this: Since 2013, I have never reconsidered a Blackvue camera. Ever.

    If I ever need a 2-channel system, I'd be happier installing two separate cameras. That's just me.

    [MENTION=6481]wirelessandy[/MENTION] Thanks! I know EXACTLY how you feel. While I initially felt that the Blackvue 650's size and features would be ideal for me, I have spent way toooo much time and have experienced toooo much aggravation in trying to obtain video quality from the 650GW, when I see far superior video quality on dashcams that are much less expensive! And now, the problem with providing power to the rear camera is just about that "Straw that broke the camel's back" for me! Anyway, Thanks again for your input, and especially the link to your DR550GW review.

    I do tell everyone who has asked me (well, exactly zero people): Look at the bitrate. If it's low, there's not a whole lot you can do in terms of quality. This doesn't mean a high bitrate assures a good clip, but it helps.

    I've just spoken again with Gabriel from The Dashcam Store. He has been a great help to me in my efforts to get power to the rear camera. I have ordered a new Rear Camera Connection Cable from The Dashcam Store. When it arrives I'll connect it to the front and rear cameras and, hopefully, power will be restored to the rear camera. I'll just drape the cable over the seats in this troubleshooting effort. If the new cable works great. If not, rather than having the front camera repaired, I'll install a new front and rear camera. It looks like a lot of money being spent, due to a component (center conductor pin), or V input port on the front camera, being a weak link in the Blackvue DR650GW-2CH system!

    [MENTION=6481]wirelessandy[/MENTION] What dashcam system are you using now, if you have one installed? I'll do a lot of reading on the subject, but what front and rear camera system(s) do you recommend I take a look at? TIA

    At the MOMENT (until something better comes out I can live with) I'm using the Viofo A119s. Nothing for the rear (yet.)

    [MENTION=6481]wirelessandy[/MENTION] Thanks! I have seen the A119s being written about quite often lately. I'll check into it, read some articles, user experiences, etc., in order to be prepared, in case the rear camera power problem turns out to be more than just a Rear Camera Connection Cable problem. Again, Thanks for your help, I appreciate it!

    If the new cable doesn't do the trick, let us know and we'll work with you to replace the front camera so that you don't need to purchase a new one. :)

    Hi Andrew,

    Before I get in to discussing my dashcam situation, I want to sincerely Thank You, not only for what you have written in your Post, but also for your past assistance, and for your employees, especially Gabriel, who offered to help me, last week, when I know he must be extremely busy with other business responsibilities. I have nothing but the Highest Praise for your entire business. I have ordered all my dashcam accessories from your business, and I will continue to do so in the future. If I can ever be an influence on other dashcam buyers, I will recommend they contact your business! Please convey my Thanks, again, to Gabriel, for his help.

    Now to my dashcam. When I last spoke with Gabriel, last Friday, the rear camera of my Blackvue DR650GW-2CH was not operating. It was not getting power. It was not recording. The white LED light on the side of the camera was not lit. I ordered a new Rear Camera Connection Cable, which arrived yesterday Feb. 15. Yesterday, before the cable arrived, I drove my car for the first time since last Friday. I did not change anything with or on the dashcam system or its Configuration settings. Again, I did not change anything. After I returned home yesterday, I took the microSD card out of the front camera, as I wanted to view the video. I nearly fell over when I saw that there were not only front camera video files, but also rear camera video files! I selected a video in order to start the playback, and there they were....both front and rear videos. I went out to the car, inserted the microSD card into the slot, applied power to the camera, and looked at the rear camera.......and the white LED light was ON!!!

    I have absolutely no idea as to why the system did not provide power to the rear camera, and thus no videos were recorded. I also have no idea as to why the camera, on Feb. 15, had power going to the rear camera and recorded video. The Rear Camera Connection Cable was checked, and rechecked, then rechecked again last Friday. It was secure and tight on both ends. It was not touched on Wednesday. Yet the rear camera is now recording again!

    As much as I am bewildered as to why the problem took place last week, I am equally bewildered as to why the rear camera commenced operating again on Feb 15. However, I am happy and cautiously optimistic that it will continue operating normally. I will not touch the currently installed Rear Camera Connection Cable, if at all possible. I will keep the new Rear Camera Connection Cable that I ordered thru Gabriel, just in case the problem takes place again, and in case the problem is somehow caused by bad connection components on one end or the other of the Rear Camera Connection Cable.

    Andrew, Thanks again for all your help, and for Gabriel's assistance. I apologize to both of you for taking some of your valuable time in attempting to help me remedy the problem.

    I also Thank the other RDForum members for offering your help and assistance.

    I sincerely appreciate everyone's help!
