I have around 15 cameras around the house, half of them are Hikvision because they are good and only cost B550 on Lazada.
BUT a security hack can only happen if they are logged into the internet through the router or on a cloud, mine are used as surveillance and recording only to a hard disk.
The definition is quite good and can read number plates and see individual pieces of grass
The other cameras I have that are on line are VStar cam as far as I know there is not a problem with those, but if there is who cares, they are welcome to look at my perimeter wall and watch the cats outside playing in their catio ????
