Need advice on selecting IP camera compatible with Synology

[rawneat]

Hi All,

I have DS1621XS+ nas and i am looking for a compatible POE or WIFI doorbell with following requirements :
1. POE/WIFI as long as the nasi can network to it locally
2. Decent video quality
3. 24/7 recording
4. Can connnect to existing mechanical chime or has its own chime

I had purchased EZVIZ DB1C but it keeps going offline and needs constant resetting plus sound is not recorded to NAS. Thinking of Amcrest but wanted to post before buying. All suggestions are welcome.

Thanks,
