Built for professional IP-based live production

The Panasonic AG-CX370EJ expands the CX line with fully integrated IP broadcast functionality, including NDI® HX2 support for low-latency video over IP and remote camera control. Ideal for studio and field production, it also supports SRT, RTMP, RTMPS, and RTSP streaming protocols, enabling direct-to-platform broadcasting in 4K. With compatibility for switchers, encoders, and remote workflows, the CX370 is engineered for the demands of modern live environments.

Broadcast-ready 12G-SDI and GENLOCK integration

The inclusion of 12G-SDI output enables uncompressed 4K signal transmission to high-end broadcast equipment, ensuring pristine image quality without additional converters. A dedicated GENLOCK input adds critical synchronisation for multi-camera productions, allowing precise timing in studio or OB van environments. Whether integrating into traditional SDI workflows or IP-based systems, the CX370 delivers flexible output options for professional deployment.

High-performance imaging with 1.0-type sensor and 20x zoom

At the heart of the CX370 is a 1.0-type 15MP MOS sensor, providing excellent low-light performance, shallow depth of field, and detailed 4K capture. The 24.5mm wide-angle lens offers a cinematic field of view, while the 20x optical zoom and i.Zoom extend reach without compromising quality. This optical system is enhanced by intelligent autofocus with face detection and reliable subject tracking.

10-bit 4K60p HEVC recording with HDR options

The AG-CX370EJ records in HEVC/H.265 at 10-bit 4:2:2, delivering high-quality 4K60p footage at reduced bitrates, ideal for long-form capture or streaming. Users can choose between Hybrid Log-Gamma (HLG) and V-Log, supporting HDR broadcast standards and grading flexibility in post. Dual SD card slots enable relay or simultaneous recording for extended shoots and backup.

Flexible multi-channel audio input and control

Designed for professional sound capture, the CX370 includes two XLR inputs and a 3.5mm stereo input, supporting 4-channel LPCM audio with independent volume controls. This allows operators to run multiple mics or mix line-level sources directly in-camera. Whether filming a documentary, live event, or studio interview, the CX370 offers robust audio handling without external recorders.

Optimised for mobile, multi-platform production

Despite its advanced feature set, the CX370 remains compact and field-friendly at just approx. 2.0 kg with battery and accessories. The built-in 5-axis hybrid image stabiliser ensures steady shots during handheld use, while IP control over LAN and USB tethering streamline remote management. With support for wired, Wi-Fi, and mobile network connections (via optional AJ-WM50E), it's fully prepared for rapid deployment in remote and mobile production setups.

What's in the box?

FAQs:

What’s the difference between the Panasonic AG-CX370EJ and the AG-CX350?

The CX370 adds 12G-SDI output, GENLOCK input, and NDI® HX2 IP connectivity, making it better suited for live production and multicam broadcast setups. Both share the same 1.0-type 15MP sensor and 10-bit 4K60p HEVC recording, but the CX370 is designed for seamless integration with professional IP systems and uncompressed 4K output.

Is the Panasonic AG-CX370EJ better for live streaming than the HC-X20?

Yes — the CX370 offers NDI® HX2, SRT, and simultaneous SDI/HDMI 4K output, giving it more flexibility for professional live streaming. The HC-X20 is a strong all-rounder, but the CX370 is optimised for IP-based production and streaming into broadcast systems or switchers.

What power options are available for the Panasonic AG-CX370EJ?

The CX370EJ can be powered using a 7.28V battery or via 12V DC input from the supplied AC adaptor. Its power consumption is approx. 26W during operation, making it suitable for extended production days using V-mount adapters or high-capacity camcorder batteries. For users building a mobile rig, the 12V DC input (EIAJ Type 4) offers flexible powering through broadcast battery systems.

What memory cards are compatible with the CX370EJ?

The CX370EJ uses dual SDXC UHS-II card slots and supports V90 video speed class, making it ideal for high-bitrate 10-bit 4K60p recording. It’s compatible with UHS-I and UHS-II SD cards, but to ensure reliable recording, especially for HEVC and high frame rate footage, V90-rated SDXC cards are recommended. Recording modes include relay, simultaneous, and background capture.

Does the Panasonic AG-CX370EJ support timecode and multi-cam sync?

Yes — the camera includes a BNC TC IN/OUT port for professional timecode input or output, along with a GENLOCK IN connector for sync in multi-camera environments. These are essential for synchronising multiple units during live production or when using external recorders, switchers, or editing systems that rely on frame-accurate sync.
