How to convert the digital signal of the front-end network camera into analog signal and access it to the existing DVR hard disk recorder (without NVR)?
First, at present, many network cameras have analog output, that is, BNC interface output, which can be directly connected to DVR. Devices like ours all have this function.
Second: Even if there is no network camera with analog output, you need to find the manufacturer of the network camera you bought, then buy their decoder, decode the network camera, restore the analog signal, and then connect the DVR.
Thirdly, the encoder means to convert analog into digital, while the decoder means the opposite, that is, to convert digital into analog. The decoding can generally be stored in DVR or decoded on the wall.
