Selection notes

• Confirm the complete DS-2CD2955G0-ISU identity, exact lens option, actual supplied hardware and recording settings.
• ISD confirms supply, stock, price, lead time, local warranty and package contents separately.
• Match the exact camera, lens, recorder, firmware, 50 Hz or 60 Hz mode and codecs; named protocols do not guarantee arbitrary-device compatibility.
• DORI, illumination and target-event references depend on scene, mounting and settings; they are not guaranteed identification distances.
• Mounts, adapters, cards and power supplies are not assumed included. Confirm the complete accessory combination and actual mounting geometry.
• Historic browser/security fields, file dates and printed codes do not establish present browser compatibility, installed firmware or current security status.
