At our first ever IPVM seminar, we held a number of real time polls asking attendees what they thought on a variety of important surveillance topics. We found the results to be quite interesting.
Below are 7 of the poll results answering the following questions:
- A 5MP camera is equivalent to how many analog cameras?
- How reliable is the pixels per foot metric?
- What lens do you usually use?
- How important is low price for entry level VMS ($50 vs $100)?
- Is VSaaS a threat to VMS software?
- Do you recommend VMS Appliances (Intransa, Pivot3, etc)?
- What level of gain control do you use?
Of course, these results are not scientific. More importantly, the results are skewed by the type of audience attending which primarily consisted of technology people / surveillance experts. As such the results are more likely to show what well educated domain experts believe rather than the general opinion in the surveillance market.
Here is one of the most interesting poll results:
I was pleasantly surprised to see this. While the 'marketing' answer is 15 to 17 analog cameras (because a 5MP camera has ~15-17x the number of pixels), in reality the practical benefits are far less. Attendees cited obvious logistical limitations such as walls, poles and other obstructions wasting the extra pixels, lens limitations and environmental factors such as harsh light and low light reducing the true increase in quality.
