A PoE injector can add power to a suitable network connection. This can be useful for one camera when the existing switch does not have a suitable PoE port. Choose the injector based on the camera, not only on the shape of the plug.
Locate the supported PoE standard and the required power for the exact model. Determine whether the intended injector fits with it. An unknown passive power supply is not interchangeable with any standardized PoE solution. Use only a combination whose suitability has been confirmed.
Check the port labels and the connection diagram of the injector. The connection from the router or switch has a different function than the powered connection to the camera. Label both cables if the injector is placed behind a cabinet or in a technical room.
The injector itself needs a suitable power connection and environment. Plan where it remains accessible for inspection, without hanging loose between cables. Check the operating conditions before placing a power supply in a damp storage area or outdoor enclosure.
An injector does not automatically extend each cable connection to an unlimited distance. Let the existing path, connections, and camera be evaluated together. If the intention is to expand multiple cameras, also compare a suitable PoE switch with multiple separate power supplies.
After connecting, check the live feed, recording, and the functions that may require additional power. Record the injector model on the camera it is connected to. This way, during maintenance, a power supply can be identified without guessing based on a suitable plug.
No. It provides power via a network connection; for storage, a suitable power supply is required.
No. Compare standard, power and terms and conditions with the camera specification.
