Should I Recommend an IP or Analog Video Surveillance System?

In today’s world, the need for businesses to have security surveillance systems is a definite reality. Whether it’s a casino, school, office building, or convenience store; it seems that everywhere you turn, places are getting cameras installed. Have you ever had an end-user customer come to you, looking to install a surveillance network? What kind of advice did you have for them? What direction did you point them in?

The first decision to be made is whether to utilize IP or analog cameras. It is often stated that each end-user is different and that there are no “rules of thumb” that would direct someone to choose one over the other. Transition Networks would like to touch on the advantages and disadvantages of both IP and analog video systems and hopefully help yield some insight on when each system makes sense to recommend.

Advantages of IP Cameras
• Utilize existing network cabling
• Ability to utilize Power-over-Ethernet
• Able to transmit over long distances utilizing the network infrastructure
• Ability to use facial recognition analytics and other high-resolution image programs
• Can provide digital zoom and other advanced features not provided by analog cameras
Having the recording system being monitored on the IT network allows for quick responses when cameras or DVRs go down
Disadvantages of IP Cameras
• IP cameras require much more bandwidth than analog
and may exceed the user’s network capacity
• IP cameras generally cost more than analog cameras
Higher latency (time it takes for an image captured at a
camera to be presented to a user) than analog cameras

Advantages of Analog Cameras
• Analog systems are usually less costly than IP
• Analog cameras will produce images that are superior in quality and clarity, than similarly priced IP cameras
• Less complicated to implement, no need for IT expertise
• Wider camera options and variety
• Lower latency than IP cameras
Disadvantages of Analog Cameras
• Limited transmission distances
• Analog signals cannot be encrypted and can potentially be viewed by unauthorized sources
• Lack certain features like digital zoom
