Hikvision DS-2CD2T87G3-LIS2UY/SL 8MP ColorVu 3.0 Bullet Camera Light & Speaker Liveguard

For outdoor perimeter and commercial monitoring where passive recording is not enough, the DS-2CD2T87G3-LIS2UY/SL combines 8MP full-colour imaging with real-time active deterrence in a fixed bullet housing built for wall and eave mounting. Featuring ColorVu 3.0 with an F1.0 lens and Smart Hybrid Light, the camera delivers full-colour or infrared illumination up to 60 metres depending on conditions, adapting automatically between modes. Equipped with AcuSense 3.0, it filters human and vehicle targets from environmental movement to keep event logs and alerts accurate. It also includes a built-in strobe light, microphone, and speaker, enabling triggered audio-visual warnings and two-way communication when motion is detected. Built to IP67 and NEMA 4X standards, this model handles prolonged exposure to rain, dust, and corrosive coastal or industrial conditions. Available in 2.8mm and 4mm fixed lens options to suit wide-area or focused coverage needs.

Key Capabilities

Best For

• Perimeter Fence Lines and Entry Points: The strobe and audio deterrence triggers on confirmed human or vehicle detection, making this camera well suited to access control points, gate entries, and perimeter boundaries where a visible on-site response is needed.
• Commercial Yards and Loading Docks: The 8MP sensor resolves number plates, faces, and clothing detail across open yards, while Smart Hybrid Light adapts between IR and white light for consistent imaging through shift changes and after-hours periods.
• Industrial Sites with Corrosive Exposure: NEMA 4X certification covers environments with chemical wash-down, salt spray, or industrial pollutants that would degrade standard IP67-only cameras over time.
• Residential Driveways and Front Approaches: The 2.8mm lens covers a 108.8 degree horizontal field at close range, making it practical for mounting above garage doors or on eaves where a wide view of a driveway approach is needed.
• Remote or Unstaffed Locations: Two-way audio through the built-in microphone and speaker allows operators to address situations verbally from a monitoring station without needing staff physically present on site.

Why Choose the DS-2CD2T87G3-LIS2UY/SL

The DS-2CD2T87G3-LIS2UY/SL sits above basic outdoor bullet cameras by pairing an 8MP ColorVu 3.0 sensor with a complete active deterrence system in a single housing. A standard outdoor camera records events after the fact. This model adds a triggered strobe light, built-in speaker, and two-way audio to create a camera that can intervene during an incident rather than just document it. The AcuSense 3.0 engine ensures deterrence triggers on genuine human and vehicle targets rather than environmental noise, which is critical on exposed outdoor sites. The NEMA 4X rating extends beyond standard weatherproofing to cover corrosive and industrial environments, increasing the serviceable lifespan of the installation. Available through Security Wholesalers, the DS-2CD2T87G3-LIS2UY/SL suits installers and end users who need accountable outdoor coverage with on-site response capability rather than a passive recording-only solution.

Buyer Decision Tips

Key Features & Technical Specifications

Ideal Use Cases

Choosing the Right Model

• Choose the 2.8mm version if: Your mounting position is within 10 to 15 metres of the primary coverage zone and you need the widest possible horizontal field of view to cover short driveways, building corners, or compact yard areas without panning.
• Choose the 4mm version if: Your camera is mounted at height or set back from the zone you need to cover, and you require a longer DORI recognise distance to resolve detail at 20 metres or beyond, such as at gate entries or long approach paths.
• Choose a different model if: Your site requires motorised zoom to reframe coverage remotely, or wide-area panoramic coverage across multiple angles simultaneously. A fixed bullet lens is set at installation and cannot be adjusted afterwards without physically replacing the unit.
• Choose a different model if: The installation environment does not require active deterrence and the budget should be directed toward higher channel count or storage capacity instead. A standard ColorVu outdoor camera without strobe and speaker would cost less where triggered deterrence is not a priority.

FAQs

1. Does the strobe light trigger automatically, or does it need to be manually activated?
   The strobe light can be configured to trigger automatically when AcuSense 3.0 confirms a human or vehicle target within a defined zone. It can also be triggered manually through a compatible NVR or VMS interface. Scheduling and trigger sensitivity are adjustable through the camera’s configuration settings to suit site-specific requirements.
2. Is this camera genuinely suited to outdoor mounting in coastal or industrial areas?
   Yes. The NEMA 4X certification goes beyond the IP67 water and dust rating by specifically covering corrosive environmental exposure, including salt spray and chemical wash-down. This makes the DS-2CD2T87G3-LIS2UY/SL appropriate for sites near the coast, in food processing areas, or in industrial facilities where standard weatherproof cameras degrade over time.
3. What is Smart Hybrid Light and how does it differ from a standard white light camera?
   Standard white light cameras illuminate continuously at night, which uses more power and makes the camera visible at all times. Smart Hybrid Light on this model switches between infrared (for discreet, colour-neutral night imaging) and white light (for full-colour detail) based on detection events and ambient light levels. White light only activates when it is needed, reducing power draw and avoiding unnecessary illumination during quiet periods.
4. Can I use this camera without an AcuSense-compatible recorder?
   Yes. The camera can be used with any ONVIF-compatible NVR or recorder. However, AcuSense 3.0 detection events, automated deterrence scheduling, and smart alert routing work most effectively with a Hikvision NVR that supports AcuSense event handling. Without a compatible recorder, the strobe and audio features can still be configured and triggered through the camera’s local web interface.
5. Does this camera record audio as well as support two-way communication?
   The built-in microphone enables audio recording alongside video. The built-in speaker enables audio playback for live two-way communication or triggered pre-recorded warnings. Both functions are confirmed hardware features of this model. Audio recording is subject to local privacy legislation, so installers should confirm compliance requirements for the intended installation site.
6. What is the maximum detection and recognition range with each lens option?
   Using the 2.8mm lens, the DORI detection range is 89 metres and the recognition range is 17 metres. With the 4mm lens, detection extends to 109 metres and recognition to 21 metres. These figures represent the distance at which the camera can reliably detect movement and resolve enough detail to recognise a person, based on the DORI standard. Part of the Security Wholesalers range, this camera is available in both lens variants.
7. How does the F1.0 lens affect night-time image quality compared to a standard outdoor camera?
   The F1.0 aperture allows significantly more light to reach the sensor than lenses with F1.6 or F2.0 apertures. Combined with the 1/1.8″ CMOS sensor, this results in a minimum illumination of 0.0005 Lux, meaning the camera retains usable colour detail in near-dark conditions before white light is activated. In practical terms, it produces better colour imagery in dimly lit outdoor environments without relying on supplemental lighting.
