Selection notes

• Manufacturer reference for the cited configuration. Confirm the exact model, lens, hardware and firmware.
• Lens choices, storage and audio options do not confirm the supplied package. Keep full suffixes; do not substitute another camera model.
• Check recorder, codec, resolution, frame rate and firmware together. A named protocol is not universal interoperability or proof of local recording hardware.
• Lighting and DORI distances are manufacturer references, not guaranteed site detection, recognition or identification performance.
• Protection ratings do not establish salt/corrosion resistance, installation suitability or local certification.
• ISD confirms supply, price, stock, delivery, supplied lens/revision, local warranty and package contents separately.
