Thermal & Optical Bi-spectrum Network Speed Dome Camera

FAQ--Best Thermal Imaging Camera for Security and Surveillance

Q：How can I keep distant targets clear when using the long range security camera mode?

A：When operating this device as a long range security camera, it is recommended to adjust zoom and PTZ speed properly to avoid image blur caused by rapid movement. Using preset positions and automatic patrol functions helps maintain stable locking and tracking of distant targets.

Q：How can I ensure the best thermal imaging camera does not overheat during continuous operation?

A：As one of the best thermal imaging cameras, the ZN-TPS3525W2D-ES is designed with a professional heat dissipation system. However, in high-temperature environments, users should avoid direct sunlight, ensure proper ventilation, and regularly clean the housing vents to guarantee stable performance during long-time operation.

Q：Will the thermal security camera performance decrease in foggy or rainy weather?

A：Unlike traditional cameras, this thermal security camera continues to deliver reliable monitoring even in fog, haze, dust, rain, or snow. Thermal imaging can penetrate partial smoke and light fog, enabling accurate detection and tracking of targets, making it suitable for forest fire prevention, port security, and oil & gas pipeline surveillance.

Q：What should I do if the PTZ response is delayed or jerky?

A：If PTZ movement feels sluggish, first check if the firmware is up-to-date to avoid system overload. It is also recommended to use preset positions and patrol scans (up to 300 presets supported) instead of long continuous manual control. This ensures smooth operation and stable performance when using the camera as a long range security camera.

Q：How can I guarantee the thermal camera works reliably in extreme weather?

A：The ZN-TPS3525W2D-ES is built for harsh environments, operating between –45°C and +60°C, and meets IP66 and IK10 protection standards. To maintain optimal performance of this thermal camera, users should regularly clean the lens and mechanical wiper, check the housing seal, and enable built-in lightning and surge protection to ensure long-term reliability.
