Camera Overview

This advanced surveillance camera features a 1/2.5” 8 Megapixel progressive scan CMOS image sensor, offering high-resolution imagery with effective pixels measuring 3840 (H) x 2160 (V). It includes 512 MB of RAM and 32 MB of ROM, operating with a progressive scanning system. The electronic shutter speed is adjustable between auto and manual settings, ranging from 1/3 to 1/100000 seconds.

Illumination and Signal-to-Noise Ratio

The camera’s minimum illumination requirements are 0.05 Lux at F1.4 for color images at a 1/3 second exposure and 30 IRE, and 0.2 Lux at F1.4 for color images at a 1/30 second exposure and 30 IRE. It can capture images in complete darkness with IR enabled. The signal-to-noise ratio is greater than 50 dB, ensuring high-quality image output.

Infrared Capabilities

Equipped with four IR LEDs, the camera provides infrared illumination up to a distance of 100 meters (328 feet). The IR can be controlled automatically or manually, enhancing its night-time surveillance capabilities.

Lens Specifications

The camera features a motorized lens with an auto iris (HALL) and is mounted on a board-in style. The focal length ranges from 7 mm to 35 mm, with a maximum aperture of F1.4. The angle of view varies from 38° to 14° horizontally and 22° to 8° vertically. It offers a 5x optical zoom and motorized focus control, with a close focus distance of 0.6 meters.

DORI Distance

For the wide (W) lens setting:

  • Detect: 234 meters (767 feet)
  • Observe: 94 meters (308 feet)
  • Recognize: 47 meters (154 feet)
  • Identify: 23 meters (75 feet)

For the telephoto (T) lens setting:

  • Detect: 765 meters (2509 feet)
  • Observe: 306 meters (1004 feet)
  • Recognize: 153 meters (502 feet)
  • Identify: 76 meters (251 feet)


The camera supports a full range of motion with a pan range of 0° to 360°, a tilt range of 0° to 90°, and a rotation range of 0° to 360°, providing extensive coverage and flexibility in monitoring.

Intelligent Features

Event Trigger

The camera is equipped with event triggers for motion detection, video tampering, scene changes, network disconnection, IP address conflicts, illegal access, and storage anomalies.

Intelligent Video Surveillance (IVS)

IVS features include tripwire, intrusion detection, and object abandonment/missing detection. Advanced intelligent functions also include face detection.

Video Specifications

The camera supports various video compression formats, including H.265+, H.265, H.264+, and H.264. It can stream three simultaneous streams with resolutions ranging from 4K (3840×2160) to CIF (352×288/352×240). The main stream supports 4K resolution at 1 to 15 fps and 3M at 1 to 25/30 fps.

Day/Night Mode and Image Enhancements

The camera operates in day/night mode with automatic (ICR), color, and black/white settings. It supports backlight compensation (BLC), highlight compensation (HLC), and wide dynamic range (WDR). Additional image enhancements include 3D digital noise reduction (DNR), smart IR support, and various white balance settings.

Audio and Network Features

The camera includes audio capabilities with compression formats such as G.711a, G.711Mu, AAC, and G.726. Network connectivity is provided via an RJ-45 Ethernet port supporting 10/100 Base-T. It is compatible with multiple protocols, including HTTP, HTTPS, TCP, ARP, RTSP, and more. The camera supports ONVIF, PSIA, and CGI, ensuring interoperability with other devices.

Storage and Software Compatibility

Edge storage options include NAS, local PC recording, and a micro SD card up to 128 GB. The camera can be accessed via web browsers like IE, Chrome, Firefox, and Safari, and managed using software such as Smart PSS, DSS, and Easy4ip. Mobile apps are available for iOS and Android.

Certifications and Interfaces

The camera is certified with CE (EN 60950:2000), UL (UL60950-1), and FCC (FCC Part 15 Subpart B). It includes a video interface port for adjustments, audio input/output interfaces, and alarm interfaces with 2 channels in and 1 channel out.

Power and Environmental Specifications

The camera supports DC12V and PoE (802.3af, Class 0) power supplies. Power consumption is less than 12.95W. It operates in temperatures from -30° C to +60° C (-22° F to +140° F) and has an IP67 ingress protection rating and IK10 vandal resistance.

Construction and Dimensions

The camera’s casing is made of metal, with dimensions of 273.2 mm x 95.0 mm x 95.0 mm (10.76” x 3.74” x 3.74”). It has a net weight of 1.11 kg (2.44 lb) and a gross weight of 1.51 kg (3.33 lb).
