Hikvision DS-2CE78D0T-LTS 2MP Two-Way Audio Fixed Turret Camera

The Hikvision DS-2CE78D0T-LTS is a professional-grade indoor/outdoor turret camera that combines high-definition imaging, two-way audio capabilities, and advanced night vision technologies. Designed for a variety of environments — from residential spaces to commercial and industrial facilities — this camera provides reliable surveillance while allowing real-time audio communication. Its robust construction and smart features make it an ideal solution for modern security systems.

Image Sensor & Video Quality

At the core of the camera is a 2 MP CMOS image sensor, capturing video in 1920 × 1080 (Full HD) resolution. The camera delivers smooth footage at 1080p at 25/30 fps in TVI format, ensuring clear motion capture and fine detail recognition. It supports PAL/NTSC signal systems, providing compatibility with a wide range of monitoring devices.

The camera operates efficiently in low-light environments, with a minimum illumination of 0.01 Lux at F1.6 with AGC enabled, and 0 Lux with IR illumination. Its ICR (Infrared Cut Filter Removal) feature enables seamless day/night switching, ensuring continuous monitoring in all lighting conditions.

Lens & Field of View

The DS-2CE78D0T-LTS is available with fixed 2.8 mm and 3.6 mm lenses, offering flexible coverage to suit different installation scenarios:

• 2.8 mm lens: Horizontal FOV: 105°, Vertical FOV: 59°, Diagonal FOV: 127°
• 3.6 mm lens: Horizontal FOV: 87°, Vertical FOV: 46°, Diagonal FOV: 105°

The camera features a standard M12 lens mount, allowing easy upgrades or replacements if needed. Its pan, tilt, and rotation adjustment (Pan: 0°–360°, Tilt: 0°–75°, Rotate: 0°–360°) enables precise positioning to capture every critical area effectively.

Two-Way Audio

One of the standout features of this turret camera is its two-way audio capability, which allows users to listen and communicate in real time:

• Microphone: Pickup distance of up to 5 meters, providing clear audio capture.
• Speaker: Rated at 2 W, with an effective audio range of up to 5 meters.
• Audio Features: Equipped with echo cancellation, AI noise reduction, and automatic gain control, ensuring intelligible communication even in noisy environments.

This functionality makes the DS-2CE78D0T-LTS ideal for applications where live interaction is necessary, such as entrance monitoring, reception areas, or home security systems.

Illumination & Night Vision

The camera features dual smart illumination: IR and white light, both with an effective range of up to 40 meters, providing excellent night vision performance. The Smart IR technology automatically adjusts the IR intensity to prevent overexposure, while the white light provides clear, full-color images in low-light conditions.

Advanced Image Features

The DS-2CE78D0T-LTS incorporates multiple image enhancement technologies to deliver high-quality surveillance footage:

• Digital WDR (DWDR) balances bright and dark areas in a scene.
• BLC (Backlight Compensation), HLC (Highlight Compensation), and Global/HLS adjustments improve visibility in complex lighting situations.
• 3D DNR (Digital Noise Reduction) minimizes noise for clearer images.
• Day/Night Mode: Auto/Color for optimal lighting adaptation.
• White Balance: Auto and manual options for accurate color reproduction.
• Anti-banding, brightness, sharpness, and Smart IR settings allow full control over image quality.

Interface & Compatibility

The camera has one HD analog output, making it compatible with a wide range of DVRs and monitoring systems. It uses the HIKVISION-C communication protocol for secure integration with Hikvision devices.

Construction & Environmental Performance

Designed for durability, the main body is metal, while the enclosure is plastic, balancing strength with lightweight design. The camera measures Ø110 mm × 102.7 mm (Ø4.33″ × 4.04″) and weighs approximately 365 g (0.81 lb.).

It operates under extreme conditions, from -40°C to 60°C (-40°F to 140°F) with up to 90% non-condensing humidity, making it suitable for both indoor and outdoor environments. The camera is IP67-rated, offering protection against dust and water ingress.

Power & Installation

The camera operates on 12 VDC ±25%, with a maximum power consumption of 7.5 W. For best performance, it is recommended to power each camera with a single adapter. When using a high-impedance cable, such as the 18 m extension cable in the kit package, a 15 VDC adapter is recommended.

Applications & Use Cases

Ideal for residential, commercial, retail, and office environments, this turret camera provides both video surveillance and two-way audio communication. Its combination of high-resolution imaging, advanced night vision, and audio capabilities ensures comprehensive security coverage.
