CCTV adapter 12V 2A eTTo
CCTV cameras are not designed to operate at 220 volts, and the maximum voltage for CCTV cameras is 12 volts, so a device called an adapter or power supply can convert this voltage into a suitable voltage. The main function of the adapter in a CCTV camera is to convert 220V AC power supply that has alternating current or AC to 12V DC voltage, which is suitable for CCTV.
Adapters are mostly used in security cases and have advantages, for example, they have a suitable size and weight that can be easily used and can be easily replaced, that is, if one adapter fails, another adapter can be used. Replaced with similar specifications. Now, one of the disadvantages of the adapter is that it gets too hot when using that adapter, but it should be noted that by disconnecting the power and reconnecting it, this overheating of the adapter is eliminated, and other disadvantages. Noise generation when using it can be mentioned.
Another characteristic of adapters that should be considered in their selection is the amount of current passing through each adapter, which means that the larger the consumer connected to the adapter, the more current passing through it.
The term Wir loss means that the voltage received by the cable is not the same as the voltage output, which is because to install a CCTV camera if the cross section of the cables is low and the long cabling route is done, then the voltage drops. Voltage also reduces image quality and ultimately causes noise in images. CCTV cameras with a voltage of 12 volts DC have several amps, for example, they start from 1 amp to 20 amps. CCTV cameras usually need 1 to 5 amps, but cameras that have night vision capability usually have 1 amp amps, and the incompatibility of the amps with the CCTV camera reduces the image quality and creates noise in the images, and also causes overheating. The limit is transformed. CCTV cameras with CMOS sensor with power consumption between 5 to 10, their current consumption is less than 1 amp, so they use a 1 amp adapter to power the CCTV camera, but some cases to increase the life of the adapters from 2 amps. Also use.
