Comelit、Videx 与欧洲对讲门禁钥匙扣:兼容选项

Security ID Systems ·

European intercom fobs from Comelit, Videx, Urmet, and CAME span three distinct credential technologies — 125 kHz EM4100, UID-writable 13.56 MHz smart cards, and secured 13.56 MHz smart cards — and the technology determines whether a 兼容的欧盟对讲钥匙扣 是可以在可写入空白卡上生产,还是您的面板必须注册新的门禁介质。本指南将分解每个品牌的子系统,解释识别标记,并展示获得可用替换钥匙扣的实际途径。

欧洲对讲系统格局

意大利和英国主导着欧洲住宅对讲系统的制造。Comelit和Urmet是意大利品牌,在欧洲大陆的公寓楼中拥有广泛的市场渗透率; Videx 是一家总部位于英国的制造商,广泛安装在英国和爱尔兰的多租户建筑中;CAME在南欧供应对讲和门禁自动化硬件。所有这四个品牌都在感应式门禁介质标准化之前进入市场,因此每个品牌都开发了自己的门禁介质方法,而不是采用通用的开放格式。

对于住户和设施经理来说,实际后果是替换钥匙扣在品牌之间不可互换,甚至在同一品牌内,正确的门禁介质也因安装代次而异。2008年安装的Comelit楼宇可能使用与2018年安装的Comelit楼宇不同的子系统。在订购任何替换品之前,识别子系统——而不仅仅是品牌——是必不可少的第一步。

这些门禁介质在建筑层面也出了名的难以采购。安装商通常是唯一的供应商,每个钥匙扣的价格明显高于商业供应商提供的同等门禁介质。 对讲和住宅门禁 细分市场正是知识渊博的兼容门禁介质供应商能带来最大价值的利基市场。

Comelit SimpleKey 和 Videx 955 解码

Comelit的住宅感应产品线以SimpleKey平台为中心,其最广泛分发的钥匙扣型号为SK9050。 Comelit SimpleKey SK9050 兼容钥匙扣 工作频率为125 kHz,在大多数安装中,它在EM4100系列芯片上编码一个26位Wiegand派生的UID。EM4100编码是一个开放的、公开文档化的标准——读卡器简单地接收芯片的固定UID并将其上传到面板白名单。

Videx的感应钥匙扣型号为955系列,工作在相同的125 kHz频段。 Videx 955 兼容感应钥匙扣 credential uses EM4100 encoding in the majority of installations found in UK and Irish apartment blocks, though later installations introduced 13.56 MHz smart-card readers. The 955's physical form factor — a compact ISO-card-thickness fob — is distinctive and the chip technology is embedded in the fob body rather than a removable carrier.

Urmet 钥匙扣,特别是 Urmet 1125/50 兼容令牌,在其基线配置中是125 kHz EM4100,并共享相同的开放标准编码。CAME对讲门禁介质,包括 CAME TST01 compatible 卡,在住宅对讲应用中也遵循125 kHz EM4100架构,这与CAME的门禁自动化应答器卡不同,后者使用完全不同的格式。

EM4100/UID vs Secured 13.56 MHz Smart Cards: The Replacement Path

The single most important variable for any European intercom fob is whether the credential is 125 kHz EM4100/UID-based or a 13.56 MHz smart card. The 125 kHz 与 13.56 MHz 识别指南 详细介绍了物理和读卡器级别的测试,但简而言之,125 kHz 钥匙扣的读取距离更远,并且在靠近 ISO/IEC 14443 读卡器时,其手感与 13.56 MHz 钥匙扣略有不同。智能手机 NFC 扫描无结果强烈表明是 125 kHz 门禁介质。

Open EM4100 credentials and 13.56 MHz fobs programmed only with a freely writable UID can be supplied on T5577-based or UID-writable blanks, because the reader is checking only the broadcast identifier, not any cryptographic challenge-response. The blank is programmed with the authorised identifier for the site, and the panel whitelist sees an enrolled credential.

Secured 13.56 MHz smart cards — those where the panel has written sector data protected by AES or proprietary keys — operate differently. The reader issues a cryptographic challenge that the credential must answer correctly. A compatible blank for these installations is a credential the panel itself enrols, writing its own sector keys onto a blank that supports the correct 13.56 MHz smart-card variant. The 兼容卡与原装卡指南 explains this enrolment model in detail. Security ID Systems supplies both categories: writable blanks for open-standard systems, and enrollable compatible blanks for secured 13.56 MHz smart-card installations.

生产兼容的门禁挂锁

对于基于 EM4100 的安装 — 大多数 Comelit SimpleKey、Videx 955、标准 Urmet 和 CAME 门禁部署 — 生产过程需要一个工作门禁介质的 UID、一个正确外形尺寸的基于 T5577 的空白钥匙扣,以及用于将该 UID 传输到空白卡的编程。然后,空白卡会以与面板相同的方式呈现。这与用于 125 kHz LF 感应式门禁介质 商业门禁控制的流程相同,区别在于每个门禁制造商指定的挂锁主体尺寸。

格式识别指南 》介绍了读取 UID 和确认编码调制的步骤 — 这很重要,因为一些 Videx 和 Urmet 安装使用 HID 兼容的 26 位编码而不是原始 EM4100,并且这种区别对于选择空白卡很重要。提供一个工作原装挂锁给 Security ID Systems,或提供 UID 字符串和专业读取工具确认的编码,是获得正确规格兼容卡的最可靠途径。

For 13.56 MHz smart-card Comelit or Videx installations, the blank fob supplied must match the smart-card variant the panel supports — 1K, 4K, or a memory-card type — and it must be presented to the panel's enrolment function rather than programmed externally. Security ID Systems ships compatible enrollable blanks for these systems and can advise on the correct blank variant when the panel model is supplied. Gate-access credentials from the same brands, such as the CAME 和 BFT 门禁应答器卡兼容,遵循单独的应答器格式,并且与门禁挂锁系列分开采购。

如何识别和订购您的门禁挂锁

最快可靠的识别途径是提供面板型号 — 在建筑物入口处的门禁主单元上找到,通常在听筒盖后面或电气竖井的门释放控制器上。在大多数情况下,面板型号直接映射到门禁介质子系统。如果面板标签无法访问,可以使用支持 NFC 的智能手机确定钥匙扣的频率:13.56 MHz 门禁介质将被 NFC 读取器检测到;125 kHz 门禁介质将不会被检测到。旧建筑几乎普遍使用 125 kHz。

订购时,请提供已知的面板品牌和型号、已确认的频率、已获得的任何 UID 字符串以及所需数量。Security ID Systems 备有 涵盖 Comelit、Urmet 和 Videx LF 变体的欧盟门禁挂锁 以及 Urmet 1125/50 门禁令牌兼容 ,适用于最常见的 Urmet 面板系列。CAME 对讲专用门禁介质和 CAME TST01 BPT 兼容卡 ,用于组合门禁-门控面板,也备有库存。

为多位居民采购钥匙扣的楼宇经理应注意,大多数基于 EM4100 的面板维护一个简单的 UID 白名单,对注册门禁介质没有上限。在大多数情况下,无需专业设备即可将兼容钥匙扣添加到白名单 — 用于原装钥匙扣的注册程序同样适用于兼容空白卡。 联系 Security ID Systems 订购前确认您特定安装的兼容性。Security ID Systems 是一家独立的兼容门禁介质制造商和供应商,不隶属于、未获 Comelit、Videx、Urmet 或 CAME 授权或认可。

常见问题

Comelit钥匙扣能否更换为兼容门禁介质?

Most Comelit SimpleKey fobs can be supplied on a compatible T5577-based blank because they use an open 125 kHz EM4100 UID encoding — the panel checks the broadcast identifier, not a cryptographic response. Later Comelit installations using 13.56 MHz smart-card readers require an enrollable compatible blank that the panel itself programmes rather than a direct UID transfer.

Videx 955 钥匙扣使用的是什么芯片?

Standard Videx 955 proximity fobs use an EM4100-family chip operating at 125 kHz. The fob broadcasts a fixed UID that the Videx VPROX reader checks against its whitelist. Some newer Videx panel generations have moved to 13.56 MHz smart-card readers, so confirming the panel generation before ordering a compatible blank is advisable.

Are EU intercom fobs EM4100 or 13.56 MHz smart cards?

Both technologies appear across EU intercom brands depending on installation age. Comelit, Videx, Urmet, and CAME all shipped 125 kHz EM4100-based credentials in their main residential product lines, with 13.56 MHz smart-card variants introduced in later panel generations. Buildings installed before roughly 2015 are more likely to use 125 kHz EM4100; newer installations may use 13.56 MHz smart cards.

我如何知道我拥有哪种楼宇对讲机钥匙扣?

Hold the fob near an NFC-capable smartphone. A 13.56 MHz smart-card fob will be detected and return a UID; a 125 kHz EM4100 fob will not be detected at all. The panel model number — labelled on the main intercom unit or door controller — is the most definitive identifier and maps directly to the credential subsystem in most installations.

为什么配钥匙自助终端无法处理我的建筑钥匙扣?

High-street key kiosks typically handle only the most common 125 kHz EM4100 and T5577 formats and use generic fob bodies. European intercom fobs sometimes require the specific physical form factor of the original to seat properly in the reader housing, and later 13.56 MHz smart-card installations require panel enrolment rather than external programming. A specialist compatible-credential supplier handles both the form factor and the smart-card enrolment requirement.

我可以自己将兼容钥匙扣添加到我楼宇的白名单中吗?

On most EM4100-based panels — including the majority of Comelit, Videx, and Urmet installations — adding a new fob uses the same panel enrolment menu as the original credentials. The compatible blank is presented to the reader during enrolment mode and the panel stores its UID. No specialist tools are required for EM4100 systems. Systems using 13.56 MHz smart cards with keyed sectors may require the installer's access to the panel administration interface.
