Product Overview
Designed for covert indoor surveillance, the DS-2CD2D25G1/M-D/NF is a compact pinhole-style network camera that measures just 31.5 mm x 31.5 mm x 49.6 mm, allowing it to be concealed within ceilings, walls, or custom enclosures where a visible camera would be intrusive or counterproductive. Featuring a 2 MP 1/2.8″ Progressive Scan CMOS sensor and a choice of 2.8 mm or 4 mm fixed lens, it delivers 1920 x 1080 resolution in environments where the camera itself must remain undetected. Equipped with 120 dB true Wide Dynamic Range, 3D DNR, and BLC, the DS-2CD2D25G1/M-D/NF maintains usable image quality in mixed-light conditions such as retail counters near shopfronts or reception areas with window glare. It also includes a suite of smart event analytics, H.265 compression for storage efficiency, and NAS network storage support. It is well suited to installations in retail back-offices, service counters, hospitality corridors, and sensitive indoor environments where discretion is the primary requirement.
Key Capabilities
Ultra-Compact Covert Form Factor
At just 31.5 mm x 31.5 mm x 49.6 mm and approximately 93 g, this camera is engineered to be concealed within walls, ceilings, display fixtures, or purpose-built housings. Its pinhole lens design means it can monitor a space without the camera being visible to occupants or visitors.
120 dB True Wide Dynamic Range
The 120 dB WDR capability allows the camera to capture clear detail in scenes with both bright and shadowed areas simultaneously, such as a retail counter positioned in front of a window or a reception desk facing an entrance. BLC and HLC processing provide additional control in challenging lighting.
Low-Light Sensitivity at 0.002 Lux
With a minimum illumination of 0.002 Lux at F1.2 with AGC enabled, this camera retains colour imaging in dimly lit indoor environments. Note that this camera has no built-in IR illumination, so adequate ambient light is required for usable night-time footage in the covert housing.
Smart Event Analytics
The DS-2CD2D25G1/M-D/NF supports intrusion detection, line crossing, region entrance and exit, unattended baggage, object removal, audio exception, defocus detection, and scene change detection. These analytics trigger recording, email alerts, or FTP uploads, making automated monitoring practical without constant manual review.
H.265 Compression with Efficient Storage
H.265 encoding reduces file sizes significantly compared to H.264 without sacrificing resolution, which matters when covert camera footage needs to be retained for extended review periods. The camera also supports NAS storage via NFS and SMB/CIFS for network-based recording without a dedicated recorder.
Best For
- Retail and Service Counters: The compact body and 2.8 mm wide-angle lens (107.8° horizontal FOV) allow close-range monitoring of cash registers, service desks, and product displays where a standard camera would be obvious or obstructive.
- Office and Sensitive Indoor Areas: Suitable for concealed monitoring of secure rooms, server areas, or document storage where camera visibility could compromise investigative or compliance requirements.
- Hospitality Corridors and Lift Lobbies: The discreet profile allows installation in hotel corridor ceilings or lift surrounds where aesthetics and discretion are priorities, while 120 dB WDR handles the variable lighting typical of these spaces.
- Healthcare Waiting Rooms and Staff Areas: Where visible surveillance cameras may cause discomfort to patients or staff, the covert form factor allows monitoring without creating a visible security presence.
Why Choose the DS-2CD2D25G1/M-D/NF
Standard dome or bullet cameras are visible by design, which is often appropriate, but there are installations where a visible camera defeats the purpose or conflicts with the environment. The DS-2CD2D25G1/M-D/NF is built specifically for situations where the camera must remain undetected. Its body is small enough to sit within a custom housing, a display fixture, or a ceiling recess, while still delivering 2 MP full HD resolution, 120 dB WDR for counter-lit scenes, and a full suite of smart analytics including intrusion detection and line crossing. A basic pinhole camera would provide video only. This model adds H.265 compression, NAS network storage, ROI encoding, privacy masking, and an audio line input, giving integrators a professional-grade covert solution rather than a basic analogue alternative. Available at Security Wholesalers, the DS-2CD2D25G1/M-D/NF is stocked in the 2.8 mm configuration.
Buyer Decision Tips
Power Supply Requirement: The DS-2CD2D25G1/M-D/NF requires a 12 VDC power supply via a 5.5 mm coaxial power plug and draws a maximum of 1.5 W. It does not support PoE, so a separate low-voltage power source must be available at the installation point. This is an important planning consideration when concealing the camera within a wall or ceiling, as the power cable will also need to be hidden or routed discreetly.
No Built-In IR – Indoor and Ambient Light Dependent: This camera has no infrared illuminators. It relies entirely on ambient light for image capture. In very low-light or zero-light conditions, image quality will degrade. If the installation space has adequate ambient lighting at all monitored hours, this is not an issue. If the camera needs to capture usable footage in darkness or near-darkness, a camera with built-in IR illumination should be considered instead.

Ideal Use Cases
Retail Cash Register Monitoring
The 2.8 mm lens provides a 107.8° horizontal field of view at close range, making it suitable for embedding above or near a register to capture transaction detail discreetly. The 120 dB WDR manages the bright shopfront lighting common in retail environments.
Office and Secure Room Monitoring
Where standard cameras would be inappropriate or alerting, this camera can be recessed or mounted covertly. Smart event analytics including intrusion detection and region entrance triggers can automate recording when access occurs outside business hours.
Hospitality Lift and Corridor Areas
The small body can be positioned discreetly in lift surrounds, corridor ceilings, or behind decorative elements in hospitality environments where visible cameras conflict with the property aesthetic. Scene change and defocus detection assist in flagging camera interference.
Healthcare Waiting Rooms and Consultation Areas
In clinical environments where overt surveillance may cause concern for patients or staff, this covert camera provides monitoring without a visible security device. The line-in audio input allows an external microphone to be connected for audio capture if required.
Temporary and Investigative Deployments
At 93 g and with a compact rectangular body, the DS-2CD2D25G1/M-D/NF can be repositioned or redeployed quickly. Its network connectivity with support for up to 32 users and three permission levels suits temporary investigative setups where access control is important.
Choosing the Right Model
- Choose this model if: Your installation requires a fully covert camera with no visible lens or housing, the monitoring area is indoors with adequate ambient light at all times, you need smart analytics such as intrusion detection and line crossing, and a 12 VDC power source can be routed discreetly to the mounting position.
- Choose a different model if: The area to be monitored has periods of complete darkness or very low light, as this camera has no built-in IR illumination and relies entirely on ambient light. A dome or turret camera with integrated IR would be more appropriate in that scenario. Similarly, if PoE cabling is the only practical power option at the installation point, a PoE-capable camera should be selected instead.
FAQs
- Does the DS-2CD2D25G1/M-D/NF have night vision or IR illuminators?
No. This camera does not have built-in infrared illuminators. It relies on ambient light for imaging. The minimum illumination is 0.002 Lux at F1.2 with AGC enabled, which allows usable colour footage in dimly lit indoor spaces, but performance in total darkness or near-zero light conditions will be very limited. If consistent low-light or night-time capture is required, a camera with integrated IR should be used instead.
- Does this camera support PoE?
No. The DS-2CD2D25G1/M-D/NF requires a 12 VDC power supply delivered via a 5.5 mm coaxial power plug, drawing a maximum of 1.5 W. PoE is not supported. When planning a covert installation, a low-voltage 12 VDC source must be available and routed to the camera position alongside the network cable.
- What lens options are available, and which is stocked?
The DS-2CD2D25G1/M-D/NF is available with a 2.8 mm lens (107.8° horizontal FOV) or a 4 mm lens (82.8° horizontal FOV). The 2.8 mm version is confirmed in stock. The 4 mm variant provides a narrower, more directed view suited to longer indoor corridors or counter approaches where you want to reduce peripheral coverage.
- How can I record footage from this camera?
The camera connects to a network via its RJ45 Ethernet port and can be managed through Hikvision iVMS-4200 software or Hik-Connect. It supports NAS recording via NFS or SMB/CIFS protocols, meaning footage can be stored on a network-attached storage device without a dedicated DVR or NVR. It can also be integrated with a compatible Hikvision NVR over the network.
- Does the camera support audio recording?
The DS-2CD2D25G1/M-D/NF has 1 audio input (line in). This allows an external microphone to be connected for audio capture. There is no built-in microphone or built-in speaker confirmed in the product specifications, so two-way audio is not supported by this camera on its own.
- Is the DS-2CD2D25G1/M-D/NF suitable for outdoor use?
No. The product data does not specify an IP ingress protection rating, and the camera is designed for indoor installation. It should not be exposed to moisture, rain, or direct outdoor conditions. Its operating temperature range of -30 °C to 60 °C is relevant for indoor environments with temperature variation, not for outdoor mounting. Security Wholesalers stocks this camera specifically as an indoor covert solution.
