For the last five years I've had 5 cams in my vehicle.

Front + front telephoto + rear + left side + right side

Basically 360º plus

Considering adding a rear tele.

So, six channels sounds just about right.

That's my setup and plan too, though I'm considering wide angle 4K in place of telephoto for the rear.

Did you modify a dash camera or what camera do you use with a telelphoto lens?

Same camera & lens that Dashmellow linked to earlier, for my front camera:

Personally, I could do without the interior camera but I would want a secondary telephoto camera facing the front. 🙂

I never drive without one!

I'm also considering a similar varifocal lens on a Mobius 4K. Needs a bit more DIY to get it to work how I want.

I agree that mostly of these are geared towards commercial fleets. Here's one I found that appears to be a legitimate Dashcam vs CCTV and supports 4 additional cameras (5 Channels Total). Not sure the resolution as the literature is confusing. Don't know what they're saying by Main Stream and Sub-Stream.

  • Video
  • Main Stream
    CH1：1080P/720P
    CH2~CH5：720P
  • Sub-Stream
    CH1：720P/480P
    CH2~CH5：480P

The issue here is that either resolution (720p - Old High Def or 480 - DVD Standard) isn't all that great in 2022. And then how well would this handle in enclosed vehicle. My guess is lower resolutions may be due to limitations on the Front Camera processing 4 additional Streams at once and also to prevent front unit from overheating.

So running a 3 Channel and 2 Channel system will yield far better quality without the pitfalls. I.E. 2K Front + 1080P and 1080p (3 Channel) and 4k and 1080p or 2k and 1080p on a 2 Channel

As I believe you know, 😉 Hikvison dash cams, including the model you mention here got a lot of attention when they were introduced to the forum a while back. The AE-DI5042-G4 model you are referring to is an expensive commercial grade fleet management dash cam with Wi-Fi/GPS and 4G LTE, face detection, driver behavior analysis, advanced driving dssistance etc. Although it is indeed a "dash cam", it is designed and functions much like many of the CCTV network cameras of the type Hikvision is well known for.

A sub stream is used in network surveillance systems for viewing DVR video over a LAN or WAN when the resolution or frame rate of the recorded video is too high for the available bandwidth. So, where Channel 1 is 1080P/720P and Channels 2-5 are 720P, this gets recorded directly to a memory card on the camera and the sub stream consists of the same video streams at lower resolution sent over the network for remote viewing.

So, although the AE-DI5042 concept is similar to what @mentadent is postulating in that it has multiple channels it is in a different product category than the consumer style dash cams of the type Viofo is known for.

Believe I know what? The page, upon googling Multi Channel Cameras per your request, shows a commercially available 5 channel product. It may have CCTV features, but it is not a "black box" recording unit found in CCTV setups. Where the only purpose of the main unit is to stores data onto a SD card or Upload to the Cloud . The main unit is indeed a DashCam with 4 ancillary cameras attached.

This may be a more advanced setup than typically found in a consumer grade vehicle, but does not meet the standards of a DVR unit, even though it has more advanced software (face detection, driver analysis, etc) than most consumers would find useful.

1. It supports an LTE Modem
2. Main Unit is a Dash Cam
3. Main unit has 4 ancillary cameras

So this would be a 5 channel dash cam. Not the 6 channel @mentadent is seeking, but an example of a commercially available product already on the market that supports 5 channels.

I missed that, sorry. So does this camera (Mobius) let you change lenses out? Are these lenses sold by Mobius or a hobbyist DIY project?

The mobius cameras have often been amended by hobbyists to suit a variety of uses, including RC aerial video, airsoft rifle cam, dashcam, surveillance etc. They are easy to open up, and the M12 lenses are easier to replace than with almost any other small camera.
