Marshall Electronics CV-420-27X 4K UHD IP Camera | 27x Zoom HEVC/SRT
The Marshall CV-420-27X (CV42027X) is a professional-grade 4K UHD IP streaming camera built around a 1/2.5" Sony IMX317 8.57MP sensor, delivering ultra-sharp video up to 3840×2160p at 59.94fps.
Designed for both broadcast workflows and embedded vision integration, this camera combines long-range optical zoom, low-light performance, and multi-protocol IP streaming into a compact, flexible platform.
With HEVC (H.265) compression and SRT (Secure Reliable Transport) support, the CV-420-27X ensures high-quality, low-latency video transmission across unstable or bandwidth-limited networks, making it ideal for remote systems, UAVs, and distributed surveillance deployments.
The camera supports simultaneous IP and HDMI/SDI outputs, while a single Ethernet connection enables video, control, audio, and power (PoE)—simplifying system design and reducing cabling complexity.

FAQ
Is the CV-420-27X good for UAV or drone systems?
Yes. Its SRT streaming, PoE capability, and compact zoom block design make it suitable for UAV and remote deployments where bandwidth and latency are critical.
Does this camera support low-latency streaming?
Yes. With SRT and HEVC, it is optimized for lower latency compared to standard RTSP H.264 setups, especially over unstable networks.
Can it output video to multiple systems at once?
Yes. It supports simultaneous IP, HDMI, and SDI outputs, allowing integration into hybrid workflows.
Is it suitable for long-range surveillance?
Absolutely. The 27x optical zoom (up to 150mm) enables detailed imaging over long distances without relying on digital zoom.
