What do I need to know when selecting the equipment for my video surveillance system?
Minimum PC configuration to start Ivideon Server for a standard IP camera with a resolution of 640x480 and 25 frames/sec: 2-core processor 1.6 GHZ, 512 MB of RAM.
- Your computer processor works the hardest during video encoding and when the motion sensor is at work.
Web cameras make the processor of your computer work harder than anything else.
Videos from web cameras are not encoded, and video recording and transfer require additional coding.
IP cameras utilize the processor of your computer the least of all.
Videos from IP cameras are encoded, and the motion detector utilizes your processor the most in this case.
Microdigital cameras utilize your computer processor the least.
Videos from these cameras come in an encoded format. In addition, they use the camera’s built-in motion detector.
- The load will be greater with the higher resolution and greater number of frames (when using motion sensor).
- The greater the number of changes in the camera frame, the higher the load (when using a motion sensor).
- Watching videos using iOS devices (iPad, iPhone, iPod) creates additional workload due to encoding video in a special format.
When you request a video in your account or through Ivideon Client at not the maximum resolution, the processor will experience extra workload.
This is due to the necessity to re-encode the video stream in the requested quality.
- If the camera does not record in h.264 or if resolution exceeds 1280x720 or the stream is greater than 1 Mbit/s, then when a video is requested over the Internet, the video will be recoded.
For each set of cameras and their installation space, a computer must be separately tested.
Therefore, it is quite difficult to determine how many cameras can be connected for stable surveillance based on your computer.
A powerful server will be enough for hundreds of such cameras.
