What should be noticed when choosing camera power?
The attentions are as follows:
Power Choice: The power device should be lightening protection and anti-creeping with effective grounding mechanism.
Voltage Attenuation: If there are too many cameras connecting to the samr adapter, the voltage may become unstable. You are recommended to adopt short distance power supply. And for one power adapter, if you connect too many cameras, the voltage would not be stable. For the long distance power supply (more than 100 meters), you can choose a general power with 220 voltage AC, and use an adapter to change it to DC current. The nearer the adapter to the camera, the less the current loss, and the more stable the image.
When using the power cable outside, you should use a waterproof box.
