The GY-HC500/550 is equipped with a newly developed wide-angle 20x optical zoom lens to offer optimal magnification for shooting. When shooting in HD mode, Dynamic Zoom combines optical zoom and pixel mapping from a 4K image sensor to create seamless and lossless 40x zoom. Take total control of the scene with triple large rings for zoom, focus, and iris for smooth shooting. Other features include an optical image stabilizer and chromatic aberration correction.

The GY-HC500/550 is equipped with an HDR compatible HLG (Hybrid Log Gamma) mode and JVC's proprietary J-Log 1 Gamma mode. These enable high dynamic range capture of a broad color spectrum with 10-bit recording for better color grading and to avoid banding. Footage recorded in HLG mode will deliver a full HDR image when viewed on HLG-compatible monitors. The J-Log 1 mode delivers wide latitude and a high dynamic range of 800%. In the field, it's possible to record while checking the image on the camera's LCD screen or viewfinder to get a grasp of the final output.

GY-HC500 supports HLG recording which enables simple HDR workflow without color grading. Avoiding clipped highlights or shadows, images are more realistic and vibrant. BT.2020 which offers wider color gamut is also supported.

GY-HC500/550 offers dual SDHC/SDXC card slots to let you record 4K 30p/25p/24p or HD video on readily available, affordable media. Unique features using two cards include:

• Series (relay) recording mode: Continuous recording card by card.
• Clip Continuous Mode: This mode allows you to consolidate several rounds of start/stop recording into one clip.
• Dual (simultaneous) recording mode: Recording to two cards with the same format for backup or multi-purpose.
• Backup recording mode: While the Rec trigger is used to REC and STOP recording on one card, the other card can act as a continuous backup that overrides the pause function*.
  *During simultaneous backup recording in HD mode, the duplicate file records in the same file format and bit rate as the original.

Its robust body makes the GY-HC500/550 ready to work in harsh environments and situations. Excellent construction in weather resistance enables image gathering in the field with confidence.

IR filter can be switched disabled (Infrared ON) to increase infrared sensitivity for shooting in extremely low illuminance.

The GY-HC500/550 is capable of streaming LIVE HD/SD and proxy video/audio files via network up to 24Mbps with low latency. High quality, stable streaming is possible from the field using just the camera itself*. No need to carry a heavy backpack or external boxes.
*With an appropriate network connection

SRT (Secure Reliable Transport) is an open source video transport protocol that enables the delivery of high-quality and secure, low-latency video across the public Internet. SRT optimizes streaming performance across unpredictable networks with secure streams and easy firewall traversal, bringing the best quality live video over the worst networks. It accounts for packet loss, jitter, and fluctuating bandwidth, maintaining the integrity and quality of your video.

SRT provides end-to-end security, resiliency and dynamic endpoint adjustment based on real-time network conditions to deliver the best video quality at all times on any network.

SRT is built-in and can be dynamically adjusted for optimal stream performance and quality. Automatic Repeat Request (ARQ) is included with SRT. End-to-end 128/256 bit AES encryption makes sure your content is protected from contribution to distribution.

When the camera is IP connected, vital camera operations can be remotely controlled via wireless or wired LAN from a tablet, smartphone, or computer anywhere in the world. Remote control functions include lens and camera settings as well as registering zoom presets and IP connection settings.

It's possible to upload video clips to an FTP server via IP. Auto FTP function allows you to start uploading a recorded clip without opening the menu screen.

When combined with the KM-IP6000/KM-IP4100 CONNECTED CAM switchers, multi-camera synchronization is possible using Network Time Protocol. Suitable for compact live production and at-home switching, NTP is used to sychronize cameras rather than traditional sync cables.

It's possible for the person in front of the camera to engage in a 2-way interview with return video and audio while streaming live to air via IP network. This allows reporters to wirelessly receive directions from the station, and camera operators to re-adjust framing as directed from another location. Multi-camera applications are supported as well.

The JVC Connected CAM camcorders and PTZ cameras feature built-in SRT encoders with
LAN/Wireless Lan connectivity to provide broadcast-quality video over the Internet directly from the
camera, no additional backpacks or encoders needed to send ISO feeds to the remote studio.
