When a Vicon Lock is added to a basic Valkrie system (see the following diagram), it enables interfacing and synchronization to third-party devices.

Lock Studio and Lock Lab offer different features to suit a variety of applications. For more information on Vicon Locks, see the [relevant Lock guide](https://vicon-help.atlassian.net/wiki/spaces/Connect/pages/1610331) (PDF) or [Vicon Lock connectivity units](https://vicon-help.atlassian.net/wiki/spaces/Connect/pages/1609381) in the *Vicon Systems Setup Guide*.

When adding a Lock to a Vicon Valkyrie system, bear in mind the following points:

- One simple switch can support up to eight Valkyrie cameras in your system. For an explanation of the types of switches that can be included in a Valkyrie system, see [Switches in Valkyrie systems](https://vicon-help.atlassian.net/wiki/spaces/Valkyrie/pages/1758152).
- One uplink port can be used to connect to the host PC. The Ethernet switch that is connected to the host PC is known as the primary switch.
- The remaining ports can be used to connect a Vicon Lock, and/or one or more Vicon optical cameras, Note that a Lock (which may be connected directly or via a Lock switch, depending on your system requirements) or a Vicon optical camera takes up one port of the switch.
- If you want to use more than eight Valkyrie cameras, and/or the number of additional devices (such as Lock, etc) require more ports or more power than is provided by the primary Ethernet switch, you must add a second Ethernet switch to your system. If you're not sure if the power requirements of your devices will be met by a simple switch, see [Understand when additional switches are required](https://vicon-help.atlassian.net/wiki/spaces/Valkyrie/pages/1758152) or contact [Vicon Support](mailto:support@vicon.com) for advice.
- In a system that contains multiple Ethernet switches, the sync source must be a camera or a Lock that is connected to the primary Ethernet switch (ie, the switch that is connected to the PC).

This diagram shows an example of a basic Valkyrie system with a Lock Lab to connect third-party analog devices.
