Functions
Functionalities
RxCamView

The mobile application allows for remote monitoring of a system based on 4000, AHD and Wi-Fi recorders via a smartphone with Android or iOS. The basic configuration of the recorder and cameras as well as PTZ control are available from the phone. The application allows you to connect to the recorder via P2P using a QR code, without the need for additional network configuration. In addition, it allows you to receive push alarms for selected alarm actions such as:
- crossing the line
- intrusion into the zone
- sabotage

Cooperation with cameras with a PIR detector

4000 Series recorders are able to receive a message about the detection of a moving object by a PIR detector built into the front panel of the camera. A passive infrared detector allows us to eliminate false motion detections caused by eg:
- lights of passing cars
- shadow movements
- reflections from shiny surfaces
- leaves / trees movement in the wind
The principle of operation of the PIR detector is based on the detection of heat changes in the detection zone, therefore the alarm is generated only when a human or other object that differs in temperature from the environment appears on the stage.

Configuration of cameras from the NVR

 

The recorders in combination with the cameras of the same series, apart from the configuration of basic parameters such as contrast or brightness, allow for a much more advanced interference with the camera settings. Depending on the functionality of the camera, from the recorder level it is possible, among others:
- changing the network settings of the camera
- stream parameters setting
- setting the zoom and focus in a camera with a motor zoom lens
- enabling and configuring the image analysis function
 

NMS Compatible

Novus Management System VSS software is an advanced platform for managing video monitoring system. Novus Management System VSS can combine different standards of CCTV: Analog, AHD, IP, and at the same time is a software with a high degree of flexibility, finding its application in both small and large and distributed installations

VCA Analysis

VCA (Video Content Analysis) features are a collection of techniques and algorithms that analyze and interpret video to detect threats, anomalies, or unwanted activities. VCA algorithms make it possible to detect and identify objects, analyze the movement of objects, including their tracking, but also allow, for example, face or license plate recognition. In thermal imaging cameras, VCA functions allow for early detection of fires.

The VCA in the cameras can operate automatically, without the need for human intervention, which enables a quick response to emergency situations.

ONVIF standard

The ONVIF standard allows for basic compatibility between devices from different manufacturers and brands. The camera + recorder set supporting the ONVIF standard guarantees that the camera will be found, added, recorded and will transmit information about motion detection.

H.265

The video encoding standard, which is the successor to the H.264 standard, which allows to save up to 35% of the bandwidth.

Hybrid Mode

The Novus AHD DVRs, thanks to the hybrid mode, are able to display, record and receive image analysis from including IP cameras. The combination of analog cameras with IP cameras in one recorder is particularly important in the case of modernization of the existing video monitoring system, as well as its future expansion.

AHD Multistandard

AHD recorders working in multistandard mode are able to handle analog cameras with different operating standards. Available standards are AHD, TVI, CVI, are the most common on the market, hence, the recorders will be compatible with most analog cameras from other manufacturers.
