Polyimide Film Heater For CCTV Cameras
Product Details
Jaye Heater Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of polyimide film heater for cctv cameras in China, also supports custom service. Welcome to wholesale high quality polyimide film heater for cctv cameras at competitive price from our factory.
Choosing a Polyimide (PI) film heater for CCTV cameras is a well-established solution to prevent lens fogging and icing in outdoor low-temperature environments. This type of heater, characterized by its ultra-thin, flexible, efficient, and reliable properties, ensures the camera delivers a clear image even in severe cold weather.
Core Functions and Advantages
- Anti-fogging and De-icing: By gently heating the lens or viewing window area, it raises the surface temperature slightly above the dew point, effectively preventing condensation and frost formation, ensuring 24/7 image clarity.
- Ultra-thin and Flexible: Typically only 0.1-0.3mm thick, it can easily conform to the lens barrel, front glass, or tight internal spaces without affecting the original design and installation.
- Uniform and Rapid Heating: Utilizing etched metal foil as the heating element, it provides even heat distribution with low thermal inertia, generating heat within seconds to a dozen seconds after power-on.
- Durable and Reliable: The Polyimide substrate offers high-temperature resistance (up to 200°C for long-term operation), low-temperature resistance (down to -40°C), chemical resistance, and high dielectric strength, ensuring a long operational life.
- Low Power Consumption: Low-power versions can be custom-designed, suitable for 24/7 operation with minimal impact on the camera's overall power consumption.
Key Parameters and Customization Options
When procuring or customizing a PI film heater, you should clarify the following key parameters with the supplier:
| Parameter Category | Common Range/Options | Description |
|---|---|---|
| Dimensions & Shape | Fully Customizable | Shape (circular, ring, rectangular, etc.) and size designed based on the camera's lens outer diameter, window glass dimensions, or specific installation location. |
| Operating Voltage | 3.7V, 12V, 24V, 110V, 220V, etc. | Must match the camera's power supply system; 12V or 24V DC are common for surveillance cameras. |
| Power Density | 0.03W/cm² - 2.5W/cm² | Affects heating speed and final temperature. 0.5-1.2W/cm² is typically sufficient for anti-fogging. Higher power may be needed for rapid de-icing, but a temperature controller is recommended. |
| Operating Temperature Range | -40℃ to 150℃ | Ensure the heater operates reliably at the lowest ambient temperature in your region. |
| Temperature Control Method | None (continuous heating), integrated thermistor, integrated thermal switch, etc. | For precise temperature control and energy savings, consider integrating a thermistor or thermal switch for feedback. |
| Mounting Adhesive | 3M 467/468, etc. | Most products come with high-performance pressure-sensitive adhesive on the back for easy peel-and-stick installation. |
Selection and Installation Recommendations
- Identify Installation Location: Determine whether the heater will be attached around the lens barrel, inside the front window glass, or on the inner housing wall. This dictates its shape and size.
- Calculate Required Power: Based on the area to be heated and the expected minimum ambient temperature, consult with the supplier's engineer to calculate the optimal power density. Avoid insufficient power (ineffective) or excessive power (risk of damage).
- Consider Temperature Control Strategy: For applications requiring precise temperature regulation or energy efficiency, choose a model with an integrated NTC thermistor, paired with a simple control circuit for intelligent on/off operation.
- Ensure Flat Application: During installation, ensure the mounting surface is clean, flat, and free of sharp edges to guarantee thermal conduction efficiency and prevent localized overheating that could damage the heater.
