2MP Heat Detection and Video Monitoring

The Hikvision 2MP NTC Heat Detection Camera is designed to combine conventional video surveillance with temperature monitoring. Its 2MP camera provides 1920 × 1080 video, allowing operators to view the monitored area while the NTC sensing system monitors temperature conditions.

This combination can be useful when visual confirmation and temperature-based event detection are both required. Instead of relying only on a separate temperature sensor, the camera provides visual information alongside its heat detection functionality.

Non-Contact NTC Temperature Sensing

The HF-VH223(4mm)(B) uses non-contact NTC temperature sensing to monitor temperature within selected areas of the camera view. The system can identify high-temperature conditions and generate corresponding alarm information when configured thresholds are reached.

The specified temperature measurement range is -20°C to 120°C, with a stated thermography precision of ±3°C. Temperature sensing should be treated as a monitoring function and installed according to the manufacturer’s specifications and the requirements of the intended application.

Four Temperature Detection Areas

The Hikvision HF-VH223 supports customized rectangular temperature detection regions. Up to four areas can be configured within the camera image for temperature monitoring.

Defining specific areas allows the system to concentrate temperature monitoring on selected equipment, machinery or sections of a monitored scene instead of treating the entire image as one measurement area.

High-Temperature Alarm

The HF-VH223 NTC Heat Detection Camera supports high-temperature alarm functionality. When temperature conditions within the configured monitoring areas meet the defined alarm criteria, the system can generate a corresponding event.

Temperature alarm thresholds should be configured according to the characteristics of the monitored environment and the requirements of the fire or heat monitoring application. Alarm configuration should not be treated as a substitute for a professionally designed fire detection system where one is required.

AI-Based Temperature Monitoring Functions

The Hikvision HF-VH223(4mm)(B) supports AI-related temperature alarm functions associated with on-duty and off-duty conditions. This provides additional configuration options for applications where temperature monitoring requirements may change depending on operational status.

These functions can be useful in environments where monitored equipment or areas have different acceptable temperature conditions during operating and non-operating periods.

4mm Fixed Lens

The Hikvision HF-VH223 4mm version uses a 4mm fixed lens. Lens selection affects the camera’s field of view and scene coverage, so the 4mm configuration should be selected according to the required monitoring distance and installation position.

Before installation, the viewing area should be checked to ensure that the camera provides appropriate visual coverage of the temperature monitoring zones.

2MP Image Quality

The Hikvision 2MP Heat Detection Camera provides 1920 × 1080 resolution for video monitoring. The camera also supports H.265 compression and two video streams, helping provide flexible video transmission options for compatible network surveillance systems.

Additional image functions include DWDR, 3D digital noise reduction and backlight compensation. These features can help the camera maintain useful imagery under different lighting conditions.

IR Illumination up to 30 Metres

The HF-VH223(4mm)(B) supports infrared illumination with a stated range of up to 30 metres. This provides additional visibility in low-light or nighttime conditions within suitable installation environments.

Actual night-time image performance depends on scene conditions, reflective surfaces, installation height, obstacles and the surrounding environment.

PoE and DC Power Options

The Hikvision HF-VH223 supports both DC 12V power and IEEE 802.3af PoE. Power over Ethernet can simplify installation by allowing compatible network infrastructure to carry both network communication and electrical power over the Ethernet connection.

The specified maximum power consumption is up to 6.5W. The appropriate power source and network equipment should be selected according to the complete installation requirements.

Network Connectivity

The Hikvision NTC Heat Detection Camera uses an RJ45 Ethernet interface for network connectivity. This allows the camera to transmit video and supported heat detection information over a compatible IP network.

Network configuration should take into account bandwidth, recording requirements, system architecture and the number of cameras connected to the surveillance infrastructure.

IP66 Protection

The HF-VH223 4mm features an IP66-rated enclosure according to the available product specifications. This provides protection against dust ingress and water jets from different directions.

The IP66 rating makes the camera suitable for appropriately selected indoor and outdoor environments, provided the installation conditions remain within the manufacturer’s specified operating limits.

Wide Operating Temperature Range

The Hikvision HF-VH223(4mm)(B) is specified for an operating temperature range of -30°C to 60°C. This allows the camera to be considered for a variety of environmental conditions when installed correctly.

Operating temperature and temperature measurement range are different specifications. The camera’s operating environment should remain within its specified limits, while the NTC sensing system has its own stated measurement range.

Fire and Heat Monitoring Applications

The Hikvision HF-VH223 NTC Heat Detection Camera can be considered for locations where visual surveillance and temperature monitoring are required together. Potential applications include industrial areas, equipment rooms, warehouses, production environments and other locations where abnormal temperature conditions need to be monitored.

The camera can provide visual information that helps operators understand the area associated with a temperature event. The appropriate application should always be determined according to the site’s fire risk assessment and applicable safety requirements.

Visual Confirmation of Temperature Events

One advantage of combining a camera with temperature sensing is the ability to associate a temperature event with visible imagery. When a high-temperature event occurs within a configured region, operators can use the camera view to assess the surrounding scene.

This can provide useful context during monitoring, although the camera should not be considered a replacement for other required fire protection, detection or suppression equipment.

Network-Based Alarm Monitoring

The HF-VH223(4mm)(B) is a network camera, allowing supported alarm information and video to be integrated into compatible IP-based monitoring environments. This can help bring temperature events and visual information into a centralized surveillance or monitoring platform.

The exact alarm integration features depend on the configured software, network equipment and supported system architecture.

• Industrial facilities
• Warehouses
• Equipment rooms
• Production areas
• Commercial premises
• Storage facilities
• Machinery monitoring areas
