Selection notes

• The documented specifications apply to the cited manufacturer version. Confirm the supplied hardware, firmware and accessory configuration.
• Analog video inputs and IP video inputs are separate. The manufacturer expresses IP input as a base count and an up-to maximum; the maximum is not presented as additional simultaneous channels on top of all analog inputs. Only the exact original model and cited manufacturer datasheet edition are used. No B/C/D/E, PoE, alarm or VPro suffix is inferred from a neighbouring model.
• Readers, locks, power supplies, batteries, licences and other accessories are not assumed to be included. ISD confirms specification, compatibility, supply, price, lead time and local warranty separately.
