Consumerism teaches us to want the most cutting-edge technology available, so it’s no surprise that this carries over to security cameras for your business as well. The most innovative security solutions may be on your list this year, but there’s more to making that decision than the “shiny object” syndrome. The right video surveillance cameras are the ones that work specifically with your building’s infrastructure, and you must consider the total cost of security cameras, including internet and data storage fees.
Video Resolution Basics
The quality of the security camera picture directly relates to how many pixels fit in the screen. Common presentation of pixels comes in this form: 4095 x 2160. That means there are 4095 pixels horizontally and 2160 pixels vertically. Contents in the 1980s and before was 640 x 680 or SD. As technology advances, more resolutions become available. Here are some of the common ones seen today:
- SD, Standard Definition, 640 x 680
- 720p HD, High Definition, 1280 x 720
- 1080i HD, High Definition, 1920 x 1080
- Ultra HD, 4K TV, 3840 x 2160
How Video Resolution Relates to Security Cameras
All surveillance footage was transmitted in analog at SD resolution or lower before IP cameras came on the market. Today, IP security cameras digitize and compress footage at the camera and transmit it through a network connection. This revolutionary technology allowed security camera manufacturers to gradually improve the quality of images regularly. Camera retailers expect better security cameras every year to entice their customers to buy the best products.
8K is coming soon, but right now, 4K is the highest resolution available. So, is 4K the best choice? Well, maybe not for your business. You must also consider the cost necessary to support the bandwidth and network storage for 4K resolution. Here’s a comparison of network storage and bandwidth for every hour of security camera footage.
|Video Resoltuion||Bandwith||1 Hour of Video Footage|
|4K-4095 x 2160||4.050 GB||9 Mbps|
|HD-1920 x 1080||0.90 GB||2.0 Mbps|
|HD-1280 x 720||0.450 GB||1.0 Mbps|
|SD-640 x 680||0.135 GB||0.3 Mbps|
This chart clearly illustrates how expensive 4K is when you multiply these figures by every security camera on your network. When you add the cost of the internet, the price increases even more.
So, the best security camera for your business is the one that your infrastructure supports, and that may not be 4K. It’s critical to find a balance between resolution, storage, and bandwidth that you can afford. If you have limited access to internet, then you should buy the camera that uses less bandwidth. You can always upgrade your cameras when you get a better internet solution.
