Here are some of the features that I hope will make it into the SG dual channel remote dashcam.
I might add more as I remember it. I should just start a proper excel list, define an ERS, engineering requirement specification.
- Each camera records to its own microSD card, even with 256GB, sometimes you want to keep the videos longer than 2 days worth of driving. Either that or a SATA port for an SSD disk. 500GB SSD costs the same as a 256GB microSD card, speeds are better and you can then write both cameras to the same disk.
- Bit rate is at least 18Mbit/s each on 1080p30.
- Storage is divided into 3 sections/folders, each is given a certain % of total card space: Parking, Event, Normal
- Within each storage container, the data write is looped and overwritten, yes, event event folder, this avoids having your dashcam stop recording because it filled up with event recordings. Because the event folder is seldom written to, 95% of writes occur due to bumps in the road triggering G-event and are unwanted, by having event overwritable, you allow the dashcam to continue recording without having to take out the storage card and manually delete all those damned g-event recordings.
- Cameras have sturdy mounts, I've had solid looking mounts on picture, but the screw wouldn't hold it for long and the mount would wobble. Also since the cables are quite thick, the strain in the cable itself would be liable to turn the camera. We're talking remote cameras, hence the issue.
- Availability of weatherproof cameras for outside install.
- Lighted event button: a stereo plug connector that leads to a round button holder case, the button lights up when the camera is recording, this is useful to know if the remote dashcam is working properly or not, since the main body is likely to be hidden and the cameras themselves should be kept discrete, meaning no LEDs on them. Pressing this button, triggers an event that places the current video into the event folder for safekeeping. I would mount this button within my reach, and where I could see it to confirm cameras are working. This is a bit for DIY, make sure the PCB inside for the button has a resistor in series with the LED in case people want to make the LED dimmer or brighter, because it might not be appropriate to have this button be glaringly obvious.
- Parking mode is a must. Needs to be able to work for preset X number of hours, or infinite time/until battery runs out. Some people might want to install Li-Ion battery backups instead of using their car battery.
- No driver assisting bull****. Dashcams are for video recording, not for assisting drivers with "watch out there's a car in front of you" or "slow the fk down" or "red light".
- No bling on remote cameras, completely black, screws, mounts, etc. You can put your big fat logo on the remote body where it won't be seen from outside the car.
- Dashcam body should only use one side for connections, this is so it can fit into smaller places and cables can be routed easily. Better to make the case a little bit larger to fit all the connectors than have the cables taking up room as they route to the box and require a minimum bend radius.
- Have a feature to automatically switch from 1080p60 to 1080p30 mode using a pre programmed time of day. 1080p30 during the night to help with low light scenes and 1080p60 during the day to utilize that extra light for extra frames and smoothness and detail.
