Sensitivity and treshold settings

[raidaru]

Hello everyone, I'd like some input from where to start with the trial&error settings for treshold and sensitivity in motion detection. My goal is to detect anything from small animals(cats,dogs) up to humans or any other bigger object. Sometimes I leave my garage open and wanna have the entrance covered. The only things I don't want to be triggered by are rain, snow,bugs and sun/shade. The cam is a DH-IPC-HFW1430TL2-A. The NVR is a 4216-EI. Here's a pic with the zone I wanna set up motion detection on. Thank you in advance.

Thats a low end camera using a 4MP lens with a 1/3" sensor, so don't expect much, especially at night unless you have a lot of ambient light.

The camera has no AI/IVS so you're resigned to using old fashioned MD which by nature is prone to false alerts

Each scene is so different I don't think anyone can really tell you, but I usually start with 80 sensitivity and 15-20 threshold.
Vehicle lights and shadows will be your biggest problems

Considering its job is to record only 3-4 meters away, I thought the cheapest would do the trick.There is not much going on at night as it's in a closed yard of two apartment blocks. The NVR has the AI/IVS stuff, I didn't know the camera also need that feature to be usable. The alert will be set only 4 recording, I'll set the camera inside to alert me on my phone if someone somehow breaks in (very unlikely).

Sorry I missed the NVR part. Ok then if your NVR has AI/IVS, why not use that instead of MD which is prone to a lot of false alerts

If you have an AI NVR the camera does NOT need to have it. I’m just saying you’ll be far better off using IVS
