Dahua AHD Cameras

The minimum illumination of Dahua vs. Hikvision IP cameras are also a matched game. Minimum illumination refers to the measurement of the minimum amount of light required for a CCTV camera to generate viewable images.

Camera lenses are one of the major feature to compare. The security cameras produced by both Hikvision and Dahua each allow multiple fixed lenses with different focal lengths. However, while Hikvision has 2.8mm, 4mm and 6mm, 8mm and 12mm lenses, Dahua offers only the choice of 2.8mm, 3.6mm and 6mm lenses. If you’re looking for more options, Hikvision is the front-runner.

If we compare Hikvision camera and Dahua camera both have same weight but their dimensions is different. Hikvision cameras have a dimension of 4.4 inches × 3.2 inches, while Dahua’s camera is 4.33 inches × 3.19 inches.
Dahua’s thermal camera range covers both thermal and hybrid (Thermal + Visible) cameras to meet different user demands.
Thermal cameras are widely used in applications such as perimeter protection, protection of key components (electrical facilities, gas pumps, etc.) and over-heating detection in critical infrastructure, forest fire prevention, and other scenarios.

The Dahua Thermal Temperature Monitoring Solution offers the latest hybrid thermal network camera that combines a Vanadium Oxide (VOx) sensor with a 2 MP visible-light sensor. The solution also provides a blackbody calibration device that maintains a customizable constant temperature as a reference point for the thermal camera. The thermal camera coupled with the blackbody calibration device and a feature-rich 4 TB Network Video Recorder delivers a contactless solution for continuous and non-invasive comparison of human skin temperature compared to the blackbody device. Thermal Temperature Monitoring technology enables quick detection of elevated skin temperatures compared to the customizable blackbody calibration device. Thermal imaging equipment can easily be installed and implemented to detect elevated skin temperature in environments such as airports, hospitals, clinics, office buildings, cruise ships, and any large public gathering location.

Thermal Temperature Monitoring Solution

The Dahua Thermal Temperature Monitoring Solution combines the advance hybrid thermal network camera, a blackbody calibration device, and an NVR to monitor temperatures. The Dahua solution delivers contactless and continuous non-invasive detection of elevated skin temperatures. Accurate temperature monitoring can reduce false positives, minimizing the number of people sent to secondary inspection, reducing manpower requirements and improving personnel safety.
Hybrid technology combines both thermal and visible light sensors into an integrated package. The thermal sensor provides temperature monitoring, and the visible light sensor provides visual identification; both streams are fed into the NVR for synchronized recording and playback.
The Blackbody device provides a constant reference temperature in view of the Thermal camera, assuring accurate temperature monitoring during continuous operation. Competing systems without a reference module won’t have the accuracy, or will require calibration if the ambient temperature changes. A/C units turning on and off, or a gust of wind from an entrance could easily skew readings, requiring re-calibration.
