Vegetation Monitoring with Drone Infrared Camera

Hello,

I am looking into performing vegetation analyses for restoration objectives for a project I am working on. I would like to monitor the percent cover of vegetation and change in vegetation with NDVI calculations. Does anyone have experience with sensors/camera attachments for infrared light? I'm wondering what my options are, there seems to be so much on the market (ex., infrared cameras, camera modifier attachments, multispectral cameras).

I have a DJI 4 drone

Thanks!
