I haven’t read through all 131 pages, but I’m pondering an upgrade to the dual channel camera system coming off the 9665GCV3 because I really want to start capturing what’s going on behind me. I don’t dislike my V3 at all, but wasn’t sure what my options may be aside from buying a different rearward facing camera only. Thoughts from the professionals? Thanks in advance!
There are pros and cons of a dual channel camera or two single channels.
Biggest advantages of a dual channel are:
1 - you're recording both cameras on the same memory card and the videos are always in sync.
2 - easier to review front and rear videos because they're on the same card
Disadvantage:
1 - Dual channel costs more.
2 - To get the same recording time you need a card twice as large = $$$
3 - If the front camera should fail you lose both
Advantage for 2 single channel:
1 - If one fails you can always swap the failed camera for the other if they're the same
2 - Single channel is cheaper than dual
Disadvantage:
1 - Usually more of a PITA to get to the rear camera to review videos
2 - Almost impossible to 'Lock' a video on the rear camera because it's not accessible from the driver's seat
You have to decide what's important to you and make a decision. I've gone both ways and prefer the dual channel but then I've never had a failure either.
