VISCAprotocol command list
VISCA protocol commands are used to control your LUMiO 12x, retrieve information on camera settings and get information on command send status.
VISCA commands are separated into:
- Return commands
- Control commands
- Inquiry commands
- Camera pan/tilt, zoom and exposure values
Return commands
VISCA return commands let you know if a given command is accepted, executed or if there is an error in the command itself.
Ack/completion return messages
In the table below, z = your camera's address + 8. To set your LUMiO 12x's address, use the OSD menu and navigate to SYSTEM, then ADDRESS (see Understanding OSD menu settings).
| z0 41 FF | Returned when the command is accepted (Ack) |
| z0 51 FF | Returned when the command has been executed (completion). |
Error return messages
| Syntax Error | z0 60 02 FF | Returned when the command format is different or when a command with illegal command parameters is accepted. |
| Command Not Executable | z0 61 41 FF | Returned when a command cannot be executed due to current conditions. For example, when commands controlling the focus manually are received during auto focus. |
Control commands
VISCA control commands allow you to customize your LUMiO 12x settings and issue movement commands.

FAQs
What is Pelco D protocol? ›
Pelco-D is an industry standard protocol for control of pan-tilt-zoom cameras. Typically used over an RS485 serial line.
What is a VISCA address? ›VISCA packet structure
The basic unit of VISCA communication is called a packet (Fig. 2). The first byte of the packet is called the header and comprises the sender's and receiver's addresses. For example, the header of the packet sent to the unit (address 1) from the controller (address 0) is 81H in hexadecimals.
Visca over IP offers the ability to send several different control commands over a network (RJ45) connection, without the need to add additional cabling. The AVer CL01 Camera controller can control up to 255 separate cameras on the same subnet using the Visca over IP protocol.
What is the difference between Pelco D and Pelco P? ›D and P differ on baud rates and max units able to control but are pretty similar. Coaxitron control needs both a coaxitron able camera plus a coaxitron able controller like a CXT or a MXB with coaxitron capability. Pelco's new network video recording system Endura also uses coaxitron.
Which protocol is PTZ? ›...
PTZ Camera Protocol Supported by PTZ Controller.
| Protocols | Remarks |
|---|---|
| Pelco P | |
| Sony | Sony VISCA Protocol |
| Canon | Canon VC-C50i, VC-C4 |

What is VISCA over UDP? ›Packet Sender & PTZOptics VISCA over IP
Packet Sender is a free application that you can utilize to execute HEX commands via TCP or UDP to the cameras. Once imported you can easily search the list of commands using the command titles as referenced in the PTZOptics VISCA over IP Commands document.
DHCP mode will allow your PTZ camera to assign itself an IP address based on the information your router is sending. *#4 is another shortcut that can always be used to display the IP address information that the camera currently has.
