§ 01Overview
What the HIK-2CD6520D-IO2 is
The Hikvision DS-2CD6520D-IO2 is a 2 MP inner-vehicle mini dome camera designed for the inside of buses, trains, coaches and other transport.
It is a compact, low-profile dome made to sit discreetly in a cabin ceiling or wall without taking up passenger space, and its three-axis adjustment lets you aim the view exactly where you need it during a quick install.
The IP66 and IK08 housing handles dust, splashes and the knocks of a public-transport cabin.
A 1/3" sensor records 1080p video at 30 fps, with digital WDR and 3D digital noise reduction to keep the picture usable as light changes through windows and at night.
Infrared night vision reaches up to 30 metres, which covers a typical cabin, and as with any infrared camera the image is black and white in the dark.
A built-in microphone captures audio alongside the video, useful for incident review on transport, and the camera comes with a 4 mm lens as standard, with 2.8, 6 and 8 mm options to suit different cabin sizes.
It is straightforward to wire and record.
The camera connects over a single RJ45 cable and accepts power from PoE (802.3af) or 12 VDC, so it fits neatly into a vehicle's network.
A built-in micro SD slot takes a card up to 64 GB for local backup, and it records to a Hikvision mobile NVR over the network.
It suits operators who want a simple, durable in-cabin camera with audio and clear low-light video for buses, trains and similar vehicles.

§ 09Bundles
Recommended packages
Add the right recorder
As an inner-vehicle dome it pairs with a Hikvision mobile NVR fitted in the vehicle. For a fixed-site or bench test it records to a standard PoE NVR such as the DS-7608NI-M2/8P 8-channel PoE NVR.
Add storage
Fit a 2TB surveillance hard drive in the recorder, plus a micro SD card up to 64 GB in the camera for local backup.
Cover the outside too
For an exterior, side-view camera on the same vehicle, see the DS-2XM6522G1 outer-vehicle mobile camera, or the DS-2XM6726G1-ID mobile dome for another cabin position.
