Hikvision DS-2CD2955G0-ISU Product Overview
The Hikvision DS-2CD2955G0-ISU is a compact 5MP fixed fisheye network camera for wide-area panoramic monitoring. A 1/2.7-inch progressive-scan CMOS sensor and 1.05mm fisheye lens provide a 180° horizontal, vertical and diagonal field of view, helping a single camera observe a broad indoor area without the narrow viewing angle of a conventional fixed-lens camera.
The camera records at up to 2560 × 1920 and supports multiple display modes for wall, table or ceiling installation. Built-in infrared illumination provides visibility in darkness at distances up to 8 metres, while 120dB WDR helps balance bright and shaded areas. The -U version includes a built-in microphone, and the camera also provides separate audio and alarm interfaces for compatible external equipment.
Key Benefits
-
Panoramic coverage: the 1.05mm fisheye lens captures a full 180° field of view across the horizontal, vertical and diagonal axes.
-
5MP detail: maximum 2560 × 1920 video gives more image detail than standard 1080p monitoring.
-
Flexible mounting: display and dewarping modes support wall, table and ceiling installation scenarios.
-
Low-light monitoring: built-in infrared illumination supports viewing in darkness at up to 8 metres.
-
Wide dynamic range: 120dB WDR helps retain detail when strong backlight and dark areas appear together.
-
Audio evidence: the -U model includes a built-in microphone and also provides line-level audio input and output.
-
Edge recording: a memory-card slot supports compatible cards up to 256GB.
-
PoE installation: IEEE 802.3af PoE can carry power and data over one network cable.

Panoramic Viewing and Dewarping
A fisheye lens records a circular or heavily curved panoramic image. Supported Hikvision software, compatible recorders or suitable third-party platforms can display this image in different dewarped layouts. The exact live-view, playback and dewarping options depend on the recorder or client software, so compatibility should be checked before purchase.
Installation and Compatibility
The camera can be mounted on a ceiling, wall or flat surface. Positioning affects the available panoramic display modes and the area captured, so the installation location should be planned around the required view. It connects through a 10/100Mbps Ethernet interface and can use IEEE 802.3af PoE or a correctly rated 12V DC supply.
The official specification does not state an outdoor IP weatherproof rating for this model. Do not install it in an exposed outdoor location unless it is placed inside a correctly designed protective enclosure. Confirm NVR dewarping, audio, alarm, memory-card and mounting support for the exact DS-2CD2955G0-ISU variant.
Frequently Asked Questions
What area can the 1.05mm lens cover?
The lens provides a 180° field of view horizontally, vertically and diagonally, giving panoramic coverage from one camera position.
What is the maximum resolution?
The maximum video resolution is 2560 × 1920, which is approximately 5MP.
Does the camera see in complete darkness?
Yes. Its built-in infrared light has a manufacturer-rated range of up to 8 metres, subject to the scene and installation.
Does this version have a microphone?
Yes. The DS-2CD2955G0-ISU is the -U version and includes a built-in microphone.
Can I connect an external microphone or speaker?
The camera provides one line-level audio input and one line-level audio output for compatible equipment.
Does it support local recording?
Yes. The built-in card slot supports compatible microSD, microSDHC and microSDXC cards up to 256GB.
Does the picture look curved?
The native fisheye image is panoramic and distorted by design. Compatible software or an NVR can provide dewarped views, but supported layouts vary by platform.
Can it be powered by PoE?
Yes. It supports IEEE 802.3af PoE, Class 3, as well as a correctly rated 12V DC supply.
Is it weatherproof?
No outdoor IP weatherproof rating is stated in the official specification, so it should not be described as an exposed outdoor camera.
Will any NVR dewarp the fisheye image?
No. Confirm fisheye dewarping and playback support with the intended NVR or video-management software before ordering.
