Dotworkz NVR Optimizer
With the Dotworkz NVR Optimizer, you can quickly find the right NVR server to handle you specific camera system.
The NVR Optimizer is currently based on IP cameras and Video Encoders using MJPEG images. If you plan to use MPEG4 images, please contact a Dotworkz representative. Depending on the software of choice, MPEG4 recordings can have a storage efficiency of 10% to 40% when comnpared to MPEG recordings.
The NVR Optimizer will calculate the storage requirements based entirely on your input. Storage capacity will be affected by the number of cameras, resolution, fps (frames per second) recording rate, percent of motion in one day (24hrs), and retention time for the recordings.
If a match is made with one of our NVR server lines, you will see a part number populated in the Part # window. If you have exceeded the NVR server recommendations, an error message will notify you to contact us for a better systems solution.
Realistic settings are often difficult to input. Below are some key concepts to understand the functionality of a dedicated NVR system.
The CPU of a server can only handle up to a certain amount of IP cameras. The number of cameras are also affected by the resolution and frame rate being recorded. These are recommended numbers, but not limited to, of supported cameras based on resolution:
- 50 cameras max for 320x240 and 640x480 resolution
- 36 cameras max for 1.0 Megapixel
- 32 cameras max for 2.0 Megapixel
- 28 cameras max for 3.0 Megapixel
- 18 cameras max for 5.0 Megapixel
Our calculator is not all about size. If you choose an NVR just based on storage capacity, then you are not fully optimizing the system. What differentiates our NVR lines from DELL, HP, Gateway, or IBM is that our system is design specifically for efficiency and operations based on the number of cameras, resolution, frames per second recording, and retention time. The other vendors will only sell you a based on CPU power, RAM, and Hard drive space. They have no knowledge of what it takes to build a server to handle 24/7 recordings and operations.
Did you know that regardless of Hard drive size, one physical drive can only handle up to a certain number of frames per second. Total suppported frame rate from one physical drive will decrease as the resolutions increases. For example at 640x480 one physical Hard Drive can handle up to 200 frames per second. Now if you want to record at 15fps, the HD drive will be able to handle up to 13 cameras. Later down the road you decide you need 20fps recording, this now reduces the camera support of the HD drive to 10 cameras.
