I am thinking to buy around 6 cameras to monitor different areas in and outside my house for security purpose. First thing came to my mind was those CCTV systems, wired or wireless. Good thing about them is an internal 1 to 2TB HDD to keep recording, but the let down is the horrible app to watch live feed. Also, I honestly just heard of one brand that starts with S, others are all Chinese small brands unheard of. My concern is long term support these systems can offer, e.g. apps no longer being updated and stopped working one day.
Further searching online I found out these IP cams that works either standalone or to pair with some smart hub like Google Home or Amazon Echo. Obviously some bigger brands are playing a part here like Netgear and TP-link, etc. I believe the support of their app for live feed is guaranteed? Some even offer cloud storage, which I see is a bonus (not all are free but the free-tier for about a day storage is enough for me). The biggest let down of course is the higher price tag.
Do you have any opinion that you can share?
If you do enough research you will find that the brand starting with S is the worst of them all.
Get IP cameras from a reputed Chinese brand such as Dahua, Hikvision or Vivotek and use a NAS from Qnap or Synology to run the NVR component and you will not have any of the App issues you have mentioned in your post
