Optoma ZH451ST: Compact Full HD short throw laser projector for professional presentations
When you buy the Optoma ZH451ST, you’re choosing a highly efficient projection solution designed specifically to meet the challenges of modern business and educational environments. Limited space or distracting shadows cast by the presenter often lead to disjointed presentations. The Optoma ZH451ST solves these problems with its precise short throw lens and high-brightness DuraCore laser technology. Benefit from reliable performance without the need for lamp replacements, whilst minimising your running costs. Optimise your workflow with technology designed for durability and ease of use.
The advantages of the Optoma ZH451ST at a glance:
- Full HD short throw laser projector: Project large images from a very short distance and avoid distracting shadows cast in front of the projection screen.
- Low-maintenance business projector: The DuraCore laser light source offers up to 30,000 hours of operation without the need for lamp replacement or filter maintenance.
- 4,200 lumens: Achieve clear and easily readable content at all times, even in brightly lit conference rooms.
Maximum image performance in any environment thanks to short throw optics
Experience image quality that reproduces your content precisely and vividly. The Full HD 1080p resolution, combined with a brightness of just under 4,200 lumens, delivers brilliant results that do not fade even in daylight in offices or training rooms. The integrated short throw lens with a projection ratio of 0.496:1 allows you to place the projector less than half a metre from the wall. This creates large-format images even in small huddle rooms, whilst the presenter can move around freely without obscuring the image. Thanks to the high contrast ratio of 300,000:1, text is displayed with razor-sharp clarity and graphics are rich in detail, ensuring you hold your audience’s attention.

Reliability thanks to DuraCore laser technology
Invest in a solution designed for long-term efficiency and maximum reliability. The innovative DuraCore laser technology delivers an impressive lifespan of up to 30,000 hours, guaranteeing virtually maintenance-free operation for many years. Unlike conventional projectors, there is no need for the costly and time-consuming replacement of mercury lamps. The IP6X-certified optical housing also protects the sensitive technology from dust ingress, ensuring that brightness and colour vibrancy are maintained over the long term, even under challenging conditions. This makes the device the ideal choice for demanding 24/7 continuous operation.
Flexible installation and intelligent device management in everyday business life
Make your media technology as flexible as your day-to-day work. The Optoma ZH451ST is up to 34 per cent more compact than its predecessor models and, thanks to 360-degree projection and portrait mode, can be installed in almost any orientation. The external power supply enhances reliability and simplifies installation on the ceiling or in confined spaces. For administrators, the Optoma Management Suite (OMS) offers a huge time-saving benefit: this cloud-based solution allows multiple projectors to be monitored, controlled and scheduled in real time. This minimises downtime and enables centralised support without the need for physical access to the device. A built-in 15-watt speaker and a wide range of connectivity options, including RS232, round off this professional all-in-one package for your IT infrastructure.
