Selection notes

• Confirm the complete DS-2CD2T83G2-2LI identity, exact lens, supplied hardware and selected recording mode.
• ISD confirms supply, stock, price, lead time, local warranty and package contents separately.
• Match the actual recorder, firmware, lens, 50 Hz or 60 Hz mode, PAL/NTSC system and signal format; named functions do not establish arbitrary-device compatibility.
• Lighting, WDR, DORI and event references depend on scene and settings; they are not guaranteed identification distances or alarm outcomes.
• Optional mounts, cards, adapters and power supplies are not assumed included. Confirm the complete mounting combination and geometry.
• Manual mounting-angle ranges do not mean motorized pan/tilt. Fixed-focal choices are separate order options, not a motorized varifocal lens.
• Historic security/browser fields, printed codes and file dates do not establish present compatibility, installed firmware or current security status.
• Retained (T) and Black ordering rows are separate configurations, not aliases of the unqualified catalogue model.
