IP Camera

IP cameras or network cameras are digital video cameras that transfer data across an Ethernet link. They are used most commonly for IP surveillance. IP surveillance is a digital and networked version of CCTV (Closed Circuit Television).

Advantages of IP camera

  • Remote administration
  • Digital zoom
  • Easy transfer of video and images across internet
  • Better quality of video images due to progressive scanning. This is especially true for moving targets.
  • Frame rates and resolution are adjustable
  • The communication is two way
  • Can send alerts in case of any suspicious activity
  • Cabling requirements are lower
  • It supports intelligent videos.

How to choose an IP camera

  • Location

The first thing to consider is where the camera is to be installed. For outdoor installation, always choose weatherproof, waterproof and vandal proof cameras. But if you need an indoor camera, these factors are not that important.

  • PTZ function

With a PTZ function, you can avoid dead areas. These cameras have pan, tilt and zoom features which covers around 350 degrees in pan and 90 degrees in tilt. But if you only need the camera to be used for monitoring,  fixed lens IP camera will be more than enough.

  • Resolution

Decide how important the quality of the image is to you. A VGA camera with JPEG compression will have a lesser resolution than a Megapixel IP camera with H.264 compression.

  • Wired or wireless

You will not need wired IP cameras in cases where the camera is placed far from the router or hubs or if the signal is not strong. With the wired IP camera, you will have to make sure that you install it  close to a power outlet or you may have to consider PoE IP camera, DC power pigtail or PoE splitter cable

Other things to consider

  • Try to avoid DDNS networks which may end up being complicated and P2P function should be kept in mind.
  • Depending on your needs, you may also want extra features like a micro SD/TF slot, alarm connection and a built in speaker or microphone.
