Analogue vs IP Cameras?

The main two CCTV surveillance systems are analogue and IP. They both have their own unique pros and cons. Although analogue and IP are both camera systems they both have their own application use.

IP cameras are a network-based camera system that receive video, as well as power from a network cable. IP Cameras can be connected via a POE (Power over Ethernet) switch or can be run with a 12 Volt DC power supply, in order to complete the system. The role of a POE switch is to deliver power as well as video to the NVR/Recorder to the IP Camera. An IP Camera system is connected as follows.

A network cable would be plugged into the back of the NVR. This network cable would be then plugged into a POE switch. A second network cable would be plugged into the POE switch, and then one will take that cable and plug it into the IP Camera. Should your NVR have built in POE, one does not require an external POE switch. The network cable will connect your camera and the NVR, directly.

 

Advantages of IP Cameras

  • Less cable usage (Depending on setup)
  • Only one cable is needed for power and video to and from the NVR/Recorder or switch.
  • Able to cover larger distances (up to 200m between switch and camera)
  • Capable of using licence plate recognition (NVR dependent)
  • Easier to connect

Disadvantages of IP Cameras

  • Price is significantly more than Hikvision Turbo HD cameras
  • If a POE switch is not present in the NVR, an external one must be used
  • The IT aspect when fault finding can be tedious
  • IP conflicts can occur within your home or business network
  • Specialized crimping tool is needed

An Analogue camera system is a traditional CCTV surveillance solution and can be connected using two methods. Either by using RG59 cable or network cable.

Normally we use RG59 cable when a stronger, more robust cable is required. It consists of a video cable and power cable, joined together.

When using RG59, one will connect the video cable with a BNC connection on each side of the cable from the DVR/Recorder to the camera. One will then connect the power cable from the power supply, to the camera to give it power. A male DC 12V connection is used to connect to the camera. . This makes running the cable a lot simpler as there is only one cable (Though thicker than network cable) from the DVR to the camera.

When using network cable (Cat5/Cat6/Cat7), the process is very much the same, although, video baluns are used in place of BNC connections. There are 4 pairs of cable inside of the network cable, 2 pairs for video and the other 2 pairs for supplying power. This is often much neater as a thinner cable is used. This method is more expensive, though more affordable than IP cameras.

  

Advantages of Turbo HD

  • Analogue is cost effective
  • Easy to connect (Can be installed by yourself)
  • Does not require a POE switch
  • Does not require network cable (Unless connecting to the internet)
  • No IT experience is needed

Disadvantages of Turbo HD

  • More cable is needed compared to an IP Installation
  • Power and video are two separate cables (Though joined together)
  • Chance of connection loss (BNC Damage, Power supply)
  • Hard to fault find if a lot of cameras are connected (32 channel DVR)
  • No smart features (Certain models only)
