Callaba, a privately owned company headquartered in Estonia, was founded in 2021 with approximately 10 employees. The company specializes in software development.
Callaba recently detailed a direct camera-to-cloud contribution workflow for the PTZOptics Link 4K SRT, enabling the Link 4K to be configured as an SRT Caller to send its feed directly to Callaba, according to a June 10, 2026 release. This follows a June 8, 2026 update to the company's SRT Gateway guide, authored by founder Iurii Pakholkov, which describes the software's capabilities in receiving, routing, converting, monitoring, and redistributing live video streams using SRT and other IP video protocols. Earlier, on June 6, 2026, Callaba also outlined an SRT setup for the PTZOptics Move SE, part of its Callaba 8.4 release, which uses the camera as an SRT Caller to send its encoded IP feed to a cloud SRT Listener within Callaba.
