Comparison Hikvision DS-2CE16D1T-AVFIR3 vs Hikvision DS-2CE16D1T-VFIR3

The voltage or type of power used by the camera.

It is worth saying that among such equipment it is quite rare to find models originally designed for 230 V - devices with lower supply voltages are much more widespread, in particular, 5 V, 6.5 V, 9 V, 12 V, 14 V and 24 V. To operate such a camera from an outlet, you will need a power supply; it may be included in the delivery package, but this point should be clarified separately. More specific methods of supplying energy are also possible - for example, through a specially organized low-voltage network, or from a car battery (for 12- and 24-volt models). Separately, we note that when operating via POE (see “Design and capabilities”) the supply voltage is standard 48 V, so for models with POE the power supply features are not specified.

A specific category is represented by battery-powered cameras. This power supply ensures autonomy and independence from wires, but the operating time is limited - when the charge is depleted, the camera will have to be connected to an energy source to charge the battery. Therefore, very few battery models are produced - mostly these are compact solutions with a wireless connection, for example, via Wi-Fi...(see above).

Another extraordinary option is cameras powered by a solar panel. Autonomous power supply from solar panels is used in outdoor models of CCTV cameras. During the day, they are supplied with energy from the sun's rays and at the same time accumulate a charge in the battery, which is enough to ensure the operation of the video surveillance system at night. To meet your own needs, solar panels are placed directly on the camera body or somewhere next to it. Cameras powered by solar energy are the best option for installation away from electrical civilization.
