Avigilon Alta (Openpath) 和 56-bit 卡片解析

Security ID Systems ·

An Avigilon card is a physical proximity or smart credential issued by an access-control system made by Avigilon (a Motorola Solutions company), with the most widely deployed physical format being the proprietary 56-bit Avigilon Wiegand — a facility code plus card number plus parity bits encoded at 125 kHz. Avigilon Alta, which carries the legacy of the Openpath platform acquired by Motorola in 2021, extends that ecosystem with cloud-managed, mobile-first access that can also issue HF smart credentials alongside traditional LF cards. Because the 56-bit format is rarely documented publicly and Alta deployments span both LF proximity and HF AES smart-card layers, sourcing replacement credentials can be genuinely difficult — this guide explains exactly what you are dealing with and how 兼容的 Avigilon 卡片 生产和供应。

Avigilon、Motorola Solutions 和 Alta / Openpath 平台

Avigilon 于 2004 年在温哥华成立,最初是一家视频监控专家,并以围绕其专有卡片格式构建的硬件生态系统进入门禁市场。Motorola Solutions 于 2018 年收购了 Avigilon,将其物理门禁硬件、分析摄像头和管理软件整合到 Motorola 更广泛的公共安全和企业安全产品组合中。Avigilon 品牌现在涵盖门禁控制器、读卡器、管理软件 (Avigilon Unity) 以及这些读卡器接受的门禁介质格式。

2021 年,Motorola 收购了 Openpath,一家总部位于加利福尼亚的初创公司,该公司以其针对现代商业办公室的云管理、移动优先门禁控制而闻名。Motorola 将 Openpath 平台更名为 Avigilon Alta,将其定位为传统本地部署 Avigilon Unity 系列的云原生补充。两个平台共享读卡器资产,并且都接受实体门禁介质——但 Alta 的架构设计以基于智能手机的解锁作为主要方式,实体卡片和钥匙扣作为支持的次要选项。当您需要为 Alta 安装订购替换用实体门禁介质时,这种区别很重要,因为采购路径与传统的本地部署 Avigilon 方案不同。 托管和云门禁类别 涵盖遵循类似物理-移动混合门禁介质模型的其他云平台品牌。

了解站点运行的 Avigilon 基础设施是哪一代——是传统的 Unity 硬件、Alta 云管理,还是两者的混合——决定了您需要采购的门禁介质类型。运行十年之久的 Avigilon RP40 读卡器的设施所需的门禁介质与运行 Alta 的 Wave2 读卡器的设施所需的门禁介质不同,即使两者名义上都是“Avigilon”站点。

56-Bit Avigilon Wiegand 格式解码

传统 Avigilon 安装中最常见的物理门禁介质使用专有的 56-bit Wiegand 数据结构。Wiegand 作为一种协议,通过两条信号线从卡片向读卡器传输固定宽度的二进制有效载荷;位宽和内部字段布局由供应商定义,这正是 Avigilon 与大多数通用感应式卡使用的标准 26-bit H10301 格式不同的地方。Avigilon 56-bit 帧包含一个多位设施代码、一个卡号,以及按 Avigilon 读卡器编程解码的模式排列的前导和尾随奇偶校验位。有关专有位宽与行业标准有何不同的详细解释,请参阅 完整的 Wiegand 格式指南.

56-bit 格式在 125 kHz 的标准低频感应式载波上运行——与 HID 26-bit、Indala 和大多数其他第一代 prox 门禁介质的频率相同。使其成为一种狭窄可用格式的原因是其特定的 bit 排列:Avigilon 从未公开其帧结构,并且很少有第三方编码器配置文件包含它。这种稀缺性给需要配置额外卡片或更换丢失门禁介质而无需通过 Avigilon 或 Motorola 渠道的设施经理带来了问题。兼容的 56-bit 门禁介质在 T5577 或 EM4305 LF 芯片上复制,这些芯片是可配置的可写入基板,在兼容门禁介质行业中广泛用于此类专有格式的复制。

为传统 Avigilon 站点采购兼容门禁介质时,必须准确提供设施代码和起始卡号——或者必须提交一张样本卡——以便精确匹配格式。Wiegand 读卡器对传入数据执行奇偶校验;具有不正确奇偶校验或不正确位数的门禁介质将产生读取错误而不是拒绝访问,这在测试读卡器上验证兼容性时是一个有用的诊断信号。其他具有类似狭窄 Wiegand 变体的云时代平台包括 Kastle Systems 32-bitLenel 42-bit 兼容感应式卡 ——每个都需要格式特定的编码,而不是通用的 26-bit 替代品。

Avigilon Alta 中的物理门禁介质与移动门禁介质

Avigilon Alta 旨在将智能手机作为主要的访问凭证。当用户在 Alta 云平台中注册时,会收到通过 Openpath (Alta) 应用程序交付的移动凭证,该应用程序使用低功耗蓝牙(Bluetooth Low Energy)与 Alta 读卡器通信,在支持的硬件上还会使用超宽带技术。读卡器根据云管理的访问策略验证移动凭证后授予访问权限。对于此类凭证,无需任何实体制作——凭证存在于用户的手机中,并完全通过 Alta 管理门户进行配置。

Physical cards and fobs remain a first-class option in Alta deployments for users who prefer not to use a phone, for visitor credentials, and for facilities where smartphone use is restricted. Alta-issued physical cards at the HF layer use AES-secured 13.56 MHz smart-card technology — the matching smart-card silicon with AES encryption — enrolled directly by the Alta system using its own key set. Because the smart-card credential is issued and enrolled by the Alta platform itself, a compatible supplier provides a compatible blank smart-card credential that the customer's Alta system then enrols with its own cryptographic keys. This is the correct procurement model for Alta HF cards: the supplier delivers the blank substrate; the platform provisions the credential. For context on how this compares to the genuine-vs-compatible question more broadly, 兼容与正版门禁卡:诚实的买家指南 详细介绍了这种区别。

一些 Alta 安装还在读卡器层面支持传统 LF Wiegand 门禁介质,特别是在保留了旧门禁硬件或 Alta 已叠加到现有 Avigilon Unity 基础设施的站点。在这些环境中,56-bit LF 门禁介质将继续在配置为接受它的读卡器上工作,为设施提供了一个实用的混合格式环境,其中 LF 和 HF 物理门禁介质与移动访问共存。类似的混合门禁介质部署出现在诸如 VerkadaBrivo,两者都发行物理门禁介质以及基于应用程序的访问。

编码兼容的 Avigilon 卡

生产兼容的 Avigilon 56 位门禁介质需要三个输入:正确的位帧模板、站点使用的设施代码以及要发行的卡号范围。位帧模板定义了二进制有效载荷的布局 — 字段宽度、字段顺序和奇偶校验算法。由于 Avigilon 56 位模板不是公开标准化的格式,因此使用从真实门禁介质分析中开发的专有配置文件进行编码。编码后的数据写入 125 kHz 的 T5577 或 EM4305 芯片,之后卡片在读卡器天线处与原始 Avigilon 门禁介质完全相同。

For Alta AES smart-card credentials, the process is different. A compatible Avigilon Alta 兼容卡 is supplied as a compatible blank carrying AES-secured 13.56 MHz smart-card silicon in the correct memory configuration. The blank is not pre-personalised — it arrives without Avigilon-specific application data or keys. The customer's Alta administrator imports the blank card's UID into the Alta management console and enrols it as a new credential, at which point the platform writes its own application structure and keys to the card over the air or via the Alta encoder. This keeps the cryptographic key material entirely within the customer's system and under their control.

订购前必须确定正在使用的格式。如果您有现有的门禁介质, 如何识别您的门禁卡或钥匙扣格式 提供使用智能手机 NFC 读卡器或手持分析仪的分步方法。对于 125 kHz 卡,无需任何破坏性过程即可读取芯片类型和调制。如果没有现有的门禁介质,读卡器型号和安装的软件版本将共同确认站点接受哪种门禁介质类型。

订购兼容的 Avigilon 门禁介质

Compatible Avigilon credentials are available in both the 56-bit LF proximity format and as compatible AES smart-card blanks for Alta HF deployments. For the LF format, minimum order quantities are modest — small top-ups for a few lost cards are as practical as a full batch replacement — and lead times reflect the fact that each order is encoded to the specific facility code and card number sequence you provide. The Wiegand 位格式卡 范围涵盖 Security ID Systems 提供的所有专有 Wiegand 变体,包括来自可比的云管理和企业平台的格式。

Alta AES smart-card blank credentials are supplied in standard ISO CR80 card form factor and as 30 mm key fobs, matching the form factors Avigilon uses for its own issued credentials. Order quantities start at single units for testing through to bulk batches for large tenant fit-outs. Facilities that run multiple access platforms across a campus — for instance, Avigilon alongside DMP 近场卡ATS Aritech 32 位门禁介质 — 可以通过单一供应商整合门禁介质采购,而不是为每种格式管理单独的 OEM 渠道。

要下订单或确认您特定 Avigilon 安装的兼容性, 请联系 Security ID Systems 团队 with your reader model, the credential type (LF 56-bit or HF AES smart card), and, for LF orders, the facility code and card number range. For Alta AES smart-card orders, the reader generation (Wave1 or Wave2) helps confirm the correct smart-card generation and memory layout.

常见问题

Avigilon 卡是什么格式?

Most legacy Avigilon proximity cards use a proprietary 56-bit Wiegand format consisting of a facility code, card number and parity bits, transmitted at 125 kHz. Avigilon Alta installations additionally issue HF credentials built on AES-secured 13.56 MHz smart-card technology, enrolled and managed through the Alta cloud platform. The format in use on a given site depends on the generation of Avigilon hardware installed and whether the deployment is on-premises Unity or cloud-managed Alta.

Avigilon Alta 和 Openpath 是一样的吗?

Avigilon Alta 是 Openpath 平台品牌重塑后的继任产品。Motorola Solutions 于 2021 年收购了 Openpath,并于 2022 年将产品线重新命名为 Avigilon Alta,保留了相同的云管理、移动优先架构。现有的 Openpath 硬件和门禁介质继续在 Alta 生态系统中运行,Alta 应用程序取代了 Openpath 应用程序用于移动凭证的交付。就实体门禁介质采购而言,Alta 和 Openpath 部署被视为相同。

Avigilon 56-bit 格式是什么,为什么它很难找到?

Avigilon 56-bit 格式是一种专有的 Wiegand 变体,其数据载荷比 26-bit 行业标准更宽,结构采用 Avigilon 特定的设施代码字段宽度和奇偶校验规则。Avigilon 尚未公开帧规范,因此它不会出现在标准的第三方编码器库中。有限的文档使其在兼容门禁介质市场中成为一种真正稀缺的格式 — 大多数通用感应卡供应商不提供它。

Avigilon 卡可以在不通过 Motorola 的情况下更换吗?

Yes. Compatible Avigilon 56-bit LF credentials can be produced to match the facility code and card number of an existing installation. For Alta HF AES smart-card credentials, a compatible blank is supplied and enrolled by the customer's own Alta system, so no interaction with Motorola or Avigilon channels is required. Providing the facility code and card number range, or a sample credential for format verification, is all that is needed to initiate an order.

Do you supply Avigilon Alta AES smart-card credentials?

Yes. Security ID Systems supplies compatible blank AES smart-card credentials — in both ISO CR80 card and key fob form — that carry AES-secured 13.56 MHz smart-card silicon and are formatted for enrolment by the customer's Avigilon Alta system. The blank is provided without Avigilon-specific application data; the customer's Alta administrator completes enrolment through the Alta management portal using the system's own cryptographic keys.

我如何知道我的站点使用哪种 Avigilon 门禁介质类型?

The reader model is the clearest indicator. Legacy Avigilon RP-series and AC-series readers are LF 125 kHz and accept the 56-bit Wiegand credential. Avigilon Alta Wave readers support both BLE mobile credentials and HF AES smart-card physical credentials. If you hold an existing credential, a smartphone NFC app will confirm whether it operates at 13.56 MHz (HF smart card) or returns no NFC response (LF 125 kHz). Reader model numbers and installed firmware version together confirm the full credential compatibility matrix for a given installation.

我可以在 Avigilon 读卡器中使用标准 26-bit 感应式卡吗?

No. Legacy Avigilon readers are programmed to decode the proprietary 56-bit Wiegand payload. A standard 26-bit H10301 credential presents a shorter, differently structured data frame that the reader will not recognise as a valid Avigilon credential. The reader will either ignore the card entirely or log a format error. Only credentials encoded in the correct 56-bit Avigilon frame, or AES smart-card credentials enrolled in the Alta system for HF readers, will produce a valid access decision.
