There are motion detection, motion + collision detection, collision detection, low bitrates detection on the settings, which one is best?
Thank you for your reply, which helped me a lot.I dont like motion detect as usually it record way too much as there are a lot of motion where you park, some cameras are so sensitive a cat on a fence far away that in the video can barely be seen as a cat, it will start a recording, only a very few cameras over the years have had the opposite issue and not been sensitive enough.
So my preferred parking mode is always recording low bitrate, granted it also record all the time but at a lower bitrate so should not generate as much heat inside camera as motion detect always triggered CUZ it use the normal bitrate.
If possible i also like to have G-sensor on, that way if my car is hit the actual hit will get locket ( otherwise low bitrate files will be deleted when the card is full )
Othrwise low bitrate are also flawed to a degree, say you have been parked in a place and get back to your car 4 hours later to find a dent in the car, then with no g sensor to lock the event or just act as a beacon, then you will have to sit and look thru a lot of your 4 hours of footage to find the actual event.
Mind you i only use parking guard in cameras as of lately, and only as i have to as dashcam brands sending me cameras to test have provided a hard wire kit to make that possible, and then i just use parking guard for 1 hour on the timer, or with a very high low voltage cut off if there is no timer in the camera.
At home i have CCTV on my car, so dont need parking guard there, and 1 hour cover all my shopping.
The first camera i got to do parking guard with was the SG9663DR which is a dual 1080p system, this model in regular recording using best bitrate generate 350 MB files ( 3 minute ) But when in parking mode the 3 minute low bitrate files are just 118 MB in size, so easy to tell these from the regular footage, even if they are in the same folder as regular videos.
The Viofo A139 i am currently using parking guard on, it is 1440p on the front sensor, i have totally forgotten to see what size the low bitrate parking mode files are on that camera, unlike the SG camera it do put the parking guard files in a separate folder.
At first i was unsure if low bitrate would be good, as bitrate also have a say in regard to finer detail in the video, so after i installed the system i parked my car alongside a 60 km/h road to see if it could capture little license plate details, and this worked fine ( in good daylight of course )
In Denmark faster speed roads you can not get to park at the side of the road, though on 80 km/h highways you will also find little rest stops which could be said to be roadside too, but if possible they do like to put a little more distance in between stopped cars and 80 km/h traffic.
The default town speed here is 50 km/h, and this could be 40 or maybe 30 km/h near schools ASO, some larger roads in town can be 70 km/h, these are mostly ring roads / beltways i think they are called in America, roads for traffic to bypass town centers.
The main thing if you plan to use parking guard a lot is to get a LARGE memory card, for a 2 channel system recording 1080p this should at least be 128 GB, larger will always be better, but you of course have to be mindful what the system support in memory size.
Personally i use 256GB memory cards. This with the little i drive ( 20 min daily on AVG ) and little parking guard i use ( 1 hour ) give me at least a week wort of footage.
And of course if you use parking mode A LOT ! then you have to remember, what power you use while parked need to be recharged by driving before you can park again and expect to record it.
At home if possible i will always recommend to use CCTV on the car VS using parking guard in a car parked in the driveway.
Good thing is a car charge its battery way faster than a dashcam can discharge it, but say you use parking guard for 8 hours while you sleep and 8 hours while you work, then you better do a good hour of driving every day to compensate for that drain on the battery.
And only use 12.2 V cut off on the hard wire kit, this is said to be a 50% discharged battery, any lower and you will start to dig into the life of your battery hard, and if you live in a place with cold winters it might mean you can not crank your car in the morning if the battery are way under 12 Volts.
Yeah, I‘m trying the motion+ collision detection, and find out it record so many movements.I dont like motion detect as usually it record way too much as there are a lot of motion where you park, some cameras are so sensitive a cat on a fence far away that in the video can barely be seen as a cat, it will start a recording, only a very few cameras over the years have had the opposite issue and not been sensitive enough.
