FAQ: 

1. What happens when the recorder didn't display when it turns on?

   * Equipment power supply problem;

   * cable problem (HDMI, VGA);

   * Display equipment problems;

   * The device itself (VGA or HDMI output fault)

2. What are the reasons for choosing a high-definition IP camera?

  a: The progressive scan of the end of the analog camera is not clear

  b: support PoE power supply, effective saving power supply costs

  c: megapixel resolution is more clear than analog video

  d: intelligent analysis can be integrated into the front-end to reduce the performance requirements of the back-end equipment

  f: through the network control PTZ

  g: two-way audio exchange through the network

  h: through the network control alarm input and output

  j: digital video encryption can be encrypted more secure than analog video

  k: digital video transmission through the IP network more flexible distance farther and more economical and practical

 l: Digital to avoid multiple analog-digital conversion to reduce image quality

All-digital optional open standard server hardware with lower total cost of ownership advantage.

3. Super low illumination camera and infrared led

  a: you must choose the suitable lens. In order to improve the sensitivity of the camera to the infrared led and the sensitivity, as far as possible the use of large light through the lens, and pay attention to the use of auto iris or electric. Sencond, for variable lens, as far as possible to open a large aperture drive level value. Because the general increase with the focal length of the lens, the amount of light will be relatively reduced in the choice of infrared light to stay in a certain margin, and pay attention to the infrared lamp nominal indicators.

  b.the infrared led optional power supply should be as much as possible to meet the minimum required electric power, frequent exposure distance is not enough.

  c.to consider the degree of reflection of the camera scene, because the infrared light with the same visible light, such as reflection, refraction and other characteristics, so the target scene around if there is no good reflective environment (such as buildings, walls, signs) should be considered The distance margin.
