Important Compatibility Information

Before connecting the adapter, check the power requirements printed on the camera or equipment.

The voltage must match the equipment's required input voltage. The adapter's current rating should be equal to or greater than the equipment's required current, while the connector size and polarity must also match. CCTV equipment commonly uses 5.5 × 2.1 mm connectors, but this should be verified before installation.
