# Introduction
This section introduces the Lens Heater system — a programmable solution for preventing condensation and fogging on camera trap lenses.
# Overview
The Camtraptions Lens Heater system helps prevent your valuable camera trap images from getting spoilt by condensation, dew formation and fogging.
The Lens Heater system consists of a programmable heating controller unit and a lens heater strip.
#### **Timer Functionality**
The heating controller has built-in timer functionality that operates on a **24-hour loop**, so the device can be left running unattended for many days or weeks at a time.
The controller can be set to provide heating during a time window when condensation is more likely to form (e.g. during the night), and turn off the heating automatically when dew formation is less likely to conserve power.
#### **Power Levels**
The controller offers three different heating power levels which allows further refinement of the power consumption.
# Accessories
When this system is being used with the **Camtraptions Camera Housing**, it is recommended that you use the **Heated Camera Housing Window** (purchased separately), for the ultimate power-efficient and focused heating solution.
