| ONVIF®: Onvif, the absolute standard for IP cameras. Being Onvif guarantees compatibility with any modern recording system. NOT being Onvif means having a camera for its own sake that can never be used together with recording systems. |
| POE (Power Over Ethernet): The advantage of a PoE camera is obvious, it allows it to be powered with the same cable with which it communicates without carrying additional power cables and without having to install a separate power supply system, a PoE camera guarantees constant voltages and simple installation. |
| Resolution: This camera features 2.0MP 2MP 1080P FULL-HD resolution in real time! (1920x1080pixel) Image sensor 1 / 2.7 ”2Megapixel progressive scan CMOS |
| Optics: CS Lens Mount |
Compression H.265 + 
A self-developed intelligent algorithm by Hikvision which can greatly reduce the video bitrate based on a standard H.265 codec. Hikvision's H.265 + reduces transmission bandwidth and required storage capacity without impacting video quality, thanks to three key technologies: prediction encoding, noise suppression and flexible bit rate control. Optimized for multiple surveillance scenarios, it allows for greater use of ultra HD surveillance cameras, such as 8MP and 12MP cameras. |

HIK-CONNECT Hik Connect allows you to control the device remotely
|
| ROI (Region Of Interest): The images deriving from IP cameras are “compressed”, consequently the quality is set during the recording phase. Especially on cameras with a very high resolution, it is often necessary to reduce the quality in order to guarantee a reduced bandwidth occupation and record a greater number of days or cameras. The ROI allows you to define areas where you can set a higher quality (for example a door, the area where the plate usually passes, an exit, etc.). In that area I can set a higher quality thus guaranteeing me a greater definition of the image.  |
| Day / Night: Allows you to adapt the lens to night / day vision, and the relative automatic management of the IR illuminator, when present.
|
| IR CUT FILTER (ICR): Mechanical filter that allows correct viewing of images in daytime viewing conditions. It filters the typical infrared frequencies thus improving the image quality. In night conditions the filter is removed as it is necessary to capture the typical IR frequencies.  |
|
MICRO SD SLOT: 128GB Micro SD slot ( NOT INCLUDED ) |
| BLC (Back Light Compensation): is one of the 3 possible steps in the management of images with contrast, typical situations are (entrances or exits from car parks, plates, special lights, entrances with shots from inside to outside, etc.) light compensation is one of the most complex possible, the BLC function allows a fair adaptation to these situations |
| AGC (Automatic Gain Control): integrated signal amplifier that allows viewing even in critical conditions. It is automatic and does not require specific settings. |
| ULTRA WDR up to 120dB WDR (Wide Dynamic Range): It is the professional solution in cases where it is necessary to operate in conditions of high light / shadow contrast. Fundamental in the case of shots from the inside out, license plates, shaded spots or all situations where there is no homogeneity of light.  |
