Answer:

Most security camera are made of plastic and electronic components.

Take a look what's integrates a security camera :

• 1. VISOR: it serves so that unwanted light doesn't intervene in the image captured by the surveillance camera.

• 2. IRIS: part of the optics and controls the light that enters the sensor. The iris can be manual or automatic.

• 3. OPTICS: there are different types of optics that can be adapted to the BOX surveillance cameras according to the characteristics of the sensor, iris opening, sensitivity, objectives (fixed, varifocal, motorized zoom ...), focal length ...

• 4. BOX CAMERA: the external anti-burglar video surveillance cameras allow to change the type of lens according to the angle of vision and zoom that is needed.

• 5. BALUN: transforms the transmission lines from balanced to unbalanced.

• 6. ANTI VANDALIC PROTECTION: it protects the surveillance camera from water and shock, it stays fixed capturing images of everything that happens. It is indicated for the exterior.

• 7. FAN: allows the thermal protection of the video surveillance camera, preventing its components from heating up. Its function is the same as the fan of a PC.

• 8. POWER SUPPLY: stabilizes the voltage safely protecting the components of the security camera in case of overpowering.

• 9. HEAD: allows to give the necessary angle to the security camera.

• 10. ACEROFLEX TUBE: insulates and protects the cables from water and moisture and prevents them from being cut.

• 11. SUPPORT: allows you to set the video surveillance camera on any surface.

• 12. HEATER: prevents the glass of the surveillance camera from fogging up with changes in temperature, ensuring that the image of the camera is always clear.

• 13. LIGHT DETECTOR: detects the brightness level and activates the infrared LEDs of the surveillance camera, if necessary.

• 14. CCD SENSOR: transforms the light signals received by the lens into electronic signals that can be transmitted in digital form (IP security cameras) or analog.

• 15. INFRARED LEDS: they are activated automatically when there is little illumination allowing the video surveillance camera to record in the dark in black and white.
