IP Cameras Setup Guide

A complete IP Cameras Setup Guide: Conect IP Cameras, NVR and Laptops under the same network.

Step #1. Connect IP camera to a POE switch or regular switch and a power supply

Step #2. Run on your computer the IP tool search software that comes with the camera inside the box in a CD.

Step #3. Once found the IP of the camera set the IP camera under your local network

3.1. Using internet explorer or safari, type the static IP of camera and log in to its software

3.2. Once logged in to the camera go to configuration > advance setup > network, then change the IP address, subnet mask and gateway to your local network

Step #4. Log in to NVR and insert the information of the camera

4.1 On NVR go to configuration > system setting > camera management

4.2 Under camera management, you may add thecamera manually or using quick add

4.3 Once camera added, insert user name and password of the camera, then apply

Introduction to IP Camera

Ip camera (Internet Protocol Camera) can send and receive data via a computer network or internet, while the analogs camera needs a coaxial cable to do so.

  • Centralized IP cameras, which require a central network video recorder (NVR) to handle the recording, video and alarm management.
  • Decentralized IP cameras, which do not require a central NVR, as the cameras have recording function built-in and can thus record directly to any standard storage media, such as SD cards, NAS (network-attached storage) or a PC/server.

Potential advantages of IP Cameras:

IP cameras differ from previous generation analog cameras which transmitted video signals as a voltage, instead IP cameras images are sent using the transmission and security features of the TCP/IP protocol, which provides numerous benefits:

  • Two-way audio via a single network cable allows users to listen to and speak to the subject of the video (e.g. gas station clerk assisting a customer on how to use the pay pumps)
  • The use of a Wi-Fi or wireless network.
  • Distributed intelligence such as video analytics can be placed in the camera itself allowing the camera to analyze images.
  • Transmission of commands for PTZ (pan, tilt, zoom) cameras via a single network.
  • Secure data transmission through encryption and authentication methods such as WPA, WPA2, TKIP, AES.
  • Remote accessibility [6] which allows live video from selected cameras to be viewed from any computer, mobile smartphones and other devices (with sufficient access privileges).
  • PoE Power over Ethernet to supply power through the ethernet cable and operate without a dedicated power supply.

Potential disadvantages of IP Cameras

  • Higher initial cost per camera
  • High network bandwidth requirements: A modern IP-camera using video compression require depending on compression configuration about 1-2Mbit/s per camera for typical 720p/1080p resolution at full frame rate (25/30 fps) Imaging the 3,4 and 5mp cameras available in the market. (That shall be compared with a typical CCTV camera with resolution of 640×480 pixels, 10 frames per second (10 frame/s) and a bit depth of 24-bit (uncompressed) would require over 73 Mbit/s).
  • As with a CCTV/DVR system, if the video is transmitted over the public Internet rather than a private network / intranet, the system potentially becomes open to a wider audience including hackers and hoaxers. Criminals can hack into a CCTV system to observe security measures and personnel, thereby facilitating criminal acts and rendering the surveillance counterproductive. This can be counteracted by ensuring the network and device is secured and staying informed on new security methods.
  • Public internet connection video is rather complicated to set up and requires a dynamic DNS. Some producers of IP cameras have made their own software available with built-in dynamic DNS.
