Comparison Dahua XVR5108H-I3 vs Dahua XVR5108HS-I3

The highest frame rate in the recorded video that the recorder can support when recording from all available channels simultaneously. If not all channels are occupied by cameras, this figure may be higher.

The minimum required for comfortable viewing is 24 fps. And in the most modern video standards, the frame rate can be much higher — 50 – 60 fps. Higher values result in better quality and smoother video that allows you to clearly see fast movement; however, such video takes up more space and requires powerful hardware, which affects the price of recorders.

The maximum supported recording resolution in analogue mode by the recorder. If this value is higher than the resolution when recording from all channels simultaneously (as mentioned above), it means the recorder can record at the maximum resolution only if some video channels are not occupied by cameras. Different models may require a varying number of free channels for this capability. However, there are models where the maximum resolution can be achieved even with all channels fully loaded.

The range of ambient air temperatures at which the recorder is guaranteed to remain fully operational, and the likelihood of interference and failures is minimal. In most cases, recorders are installed indoors with a quite favorable microclimate, while the operating temperature range is quite extensive — for example, a value of -10 ... +55 °C is not unusual. Therefore, you should pay attention to this indicator only when installing in difficult conditions — for example, in an unheated warehouse or in a production room with elevated temperatures.
