Hikvision HM-TD1228-7/G1/T3A thermal turret with 5 MP optical camera and temperature measurement

Thermal and optical surveillance in the same camera

HM-TD1228-7/G1/T3A is a Bi-Spectrum camera that combines thermal and optical imaging. This gives you the option to use both regular video images and thermal information from the same camera.

The thermal sensor has a resolution of 256 × 192 pixels and a pixel size of 12 μm. The camera uses a VOx UFPA detector and has a thermal sensitivity of NETD ≤ 25 mK at 25 °C and F1.0.

The high temperature sensitivity allows the camera to detect small temperature differences in the thermal image.

Thermal camera can help protect against fire

Thermal camera for perimeter security Bi-Spectrum

GUANLAN AI for people and vehicles

The camera uses Hikvision’s GUANLAN Large-Scale AI Model for perimeter protection. The AI analysis is designed to distinguish between people and vehicles and provides longer detection distance as well as a very low rate of false alarms.

This means the camera can focus alerts on relevant events instead of simply reacting to any movement in the image.

The deep learning algorithm also supports VCA detection with high precision and real-time alerts.

Temperature monitoring with alarm

HM-TD1228-7/G1/T3A can monitor temperatures from -20 °C to 150 °C. The camera can trigger an alarm when a temperature deviation is detected, so you can quickly respond to abnormal temperature conditions.

• Temperature range: -20 °C to 150 °C
• Measurement accuracy: ±8 °C
• Supports alarm for temperature deviations

This feature can be especially relevant in areas where unusual heat development needs to be detected as part of everyday video surveillance.

Detection of possible fire points

The camera supports a fire point detection algorithm. The thermal part of the camera can therefore be used to detect areas with heat development, which the algorithm identifies as a possible fire point.

This makes it possible to combine security surveillance with automatic detection of potential fire-related incidents.

Automatic smoke detection

HM-TD1228-7/G1/T3A also supports an algorithm for smoke detection. The camera can therefore analyze the surveillance area for this type of event and be part of solutions where smoke should be detected automatically.

Smart Hybrid Light with IR and white light

The camera supports Smart Hybrid Light and can work with both infrared light and white light. In addition, there is a smart mode where the lighting can be controlled according to the camera’s function.

• White light
• IR illumination
• Smart mode

This provides more options for surveillance in poor lighting conditions and makes it possible to adapt the lighting to the current situation.

Advanced processing of the thermal image

The camera includes several technologies for processing and enhancing the thermal image. This helps make temperature differences and details easier to identify under different conditions.

• Linear image processing
• Histogram image processing
• Self-adaptive thermal AGC
• DDE detail enhancement
• 3D DNR noise reduction

Suitable for many types of areas

HM-TD1228-7/G1/T3A is designed for surveillance where thermal detection, regular video, and automatic analysis need to be combined. Hikvision lists the following application areas, among others:

• Villas and homes
• Residential areas
• Parking areas
• Warehouses
• Construction sites
