I'm using Lollipop baby monitor. Recommended by my colleague and I like tt it alerts me on my hp when there's movement or sounds above a certain decibel. Can also talk over the device and play some music. Very clear night vision too.
i bought CCTV instead of baby monitor. quality and function wise ard the same or better. u can find cheap ones on shopee. baby monitor are usually more expensive.
