All about the product

Optoma ZK551 projector The Optoma ZK551 is a professional laser projector with 4K UHD resolution, designed for seamless wireless operation in offices, conference rooms, and educational institutions. With built-in video transmission technologies, the device allows instant sharing of presentations without the need for additional cables or external modules. Its compact design and high brightness ensure that this model is ideal for complex installations requiring constant readiness for work. True 4K UHD resolution and video quality The projector delivers ultra-high-definition 4K Ultra HD images, which corresponds to a display of 8.3 million pixels. This is four times the value of the Full HD standard, ensuring exceptional detail sharpness and authenticity of displayed content. The device has a CTA (Consumer Technology Association) certification and offers advanced display modes, including sRGB color reproduction, which is very important for professional graphic and video material presentations. DuraCore laser technology The heart of the ZK551 model is the laser light source, which boasts a brightness of 5100 lumens. This technology allows for high contrast and stable color performance over a long period. The lifespan of the laser module reaches up to 30,000 hours, eliminating the need to change lamps and significantly reducing maintenance work. The device has an IP6X dust resistance certification, further enhancing reliability in more challenging environmental conditions. Wireless content sharing The Optoma ZK551 is optimized for teamwork. Built-in support for Miracast, AirPlay, and Chromecast standards allows for instant screen mirroring from laptops, tablets, and smartphones. Wireless video transmission across various hardware platforms simplifies meeting management and does not require adapters or complex wired infrastructure. Installation flexibility and video correction The device features 1.6x optical zoom and a four-corner correction function, allowing each video corner to be adjusted individually. This enables the projector to be precisely aligned with the screen even on uneven walls or when mounted at an angle. An additional advantage is the 360° projection capability and portrait (vertical) mode support, which provides complete freedom in creating unconventional displays, such as in museums or galleries. Remote management and control systems The Optoma Management Suite (OMS)™ system allows IT administrators to remotely monitor, diagnose, and manage a fleet of projectors over the network. This solution enables event scheduling, sending alerts, and conducting real-time control. The ZK551 model is compatible with leading control systems, such as AMX, Crestron RoomView, and Extron IPLink, and supports an RS232 command set. Design and additional features The projector features a compact size—it's 34% smaller than previous similar Optoma models. An external power supply ensures better mobility and a more stable operation of the device. The ZK551 includes a built-in 15 W speaker that provides adequate sound volume in medium-sized rooms. A USB-A port allows powering external accessories, such as HDMI dongles. The device is designed for continuous operation 24/7.
