I have four cameras: DS-2CD2132, DS-2CD2142 and DS-2CD2163 x2 (all 4mm focal length) and I haven't been able to achieve decent night vision performance to allow adequate identification of unwelcome visitors (apart from the DC-2CD2132 installed at the front door). The picture is either too grainy or has ghost trails. Sometimes I can be hard-pressed to identify what they are wearing. Do you have any suggestions or do I need to consider changing the cameras. If so, what should I be looking...
