You need to know before purchasing a security camera that analog cameras reach a maximum of 800 lines if they do not have HD Technology. Escape from miraculous ads that say the camera has 900, 1000, 1200 lines. If it is not HD, the resolution reaches a maximum of 800 lines.

That would depend on the resolution of the camera for that.
