ANNKE I81HT 4MP PoE Fire Detection Camera | Smoke & Temperature Alarms
Smoke and flame detection
Monitor smoke, flames and selected dangerous behaviours, with additional analytics for blocked indoor access, duty status, dangerous goods and fire extinguishers.
Temperature monitoring and alarms
Thermistor sensing supports high-temperature and temperature-change alerts. This is a temperature-sensing CCTV camera, not a thermal imaging camera.
Human and vehicle perimeter detection
Intrusion and line-crossing analytics include human and vehicle filtering.
4MP detail, day and night
2688 × 1520 video, a fixed 4 mm lens and infrared illumination up to 30 metres. Frame rates reach 25 fps at 50 Hz or 30 fps at 60 Hz.
Audible warnings and status indicators
A built-in beep alarm reaches 95 dB at 10 cm. Red indicates alarm, yellow fault and green normal operation.
Listen and speak through the camera
A built-in microphone and speaker provide two-way audio.
IP67 protection
An IP67 enclosure supports indoor and outdoor installation within the specified −10°C to 40°C operating range.

Plan the installation around your site
Decide who will receive an alert and what they should do next. Ask your installer to check the viewing position, lighting, network connection and alarm settings before commissioning. Test the complete response workflow in the actual installation.
For recording options, explore the ANNKE N96PBH 16-channel PoE NVR. Confirm specialist event support for your recorder and firmware before ordering. A working video connection alone does not confirm that every camera alarm will be available on the recorder.
Questions before you buy
Can this replace a building’s fire alarm?
No. Treat camera analytics as supplementary monitoring. Keep the building’s required fire detection and alarm arrangements in place.
How should I choose the installation position?
Share your intended monitoring area with your installer before ordering. Consider obstructions and how the alarm will be checked and acted upon, then commission and test the system on site.
Can HawkVision Pro help check my system?
