Re: Sony Camera – 420 or 500 TVL – is there a difference?

RizB,

Yes there is a slightly noticeable difference in the visual resolution between a 420 and 500 TVL CCTV camera. You would see a greater difference if you went with a 600+ TVL camera. This vandal dome camera that we supply supports 620 TVL in day color mode and 700 TVL in black and white, night mode. This camera uses a Sony chip.
