Selection notes

• Confirm the complete DS-2CD2383G2-LI2U/SL identity and supplied 2.8 mm or 4 mm fixed lens; these choices are not motorized zoom.
• ISD confirms supply, stock, price, lead time, local warranty and package contents separately.
• Match the exact camera, recorder, firmware, stream settings and codecs; named protocols do not guarantee arbitrary-device compatibility.
• Recording modes depend on 50 Hz or 60 Hz selection; higher frame rates may require a lower resolution.
• DORI, illumination and human/vehicle event references depend on the scene and configuration, not guaranteed field-performance distances.
• Mounts, adapters, cards and package contents require confirmation. No memory card or separate mount is assumed included.
• Confirm the required environmental limits, mounting dimensions and exact supplied unit before choosing a housing or location.
• Third-stream prerequisite settings are not fully defined in the cited document; confirm them before relying on a third stream.
• IP67 does not establish salt/corrosion resistance, local certification or suitability for corrosive sites.
• Keep /SL separate from /SRB. The /SL warning-light branch is White Light, not the SRB red/blue branch.
