FAQ

Privacy masks is a feature that masking some area where the user doesn’t want to show.
The masked area will not be shown in either live mode or playback. These areas don’t contain any image data. Only black boxes can be seen on the screen.
Up to 16 areas for privacy masking can be set on the image.

The firmware files are different from each type of camera.
You have to prepare a firmware file(.rui) that is suitable for the camera.

1) From DirectIP NVR
In Setup > Camera > Upgrade, you can upgrade cameras directly from NVR.
Firmware files should be stored in the USB memory stick which will be connected to the NVR.

2) From IDIS Discovery
To upgrade the camera from IDIS Discovery, both PC and Camera must be in the same subnet. Verify the IP address first before trying to upgrade.
The menu for the upgrade can be found from the Management in the top menu bar.

The IK rating classifies the level of protection that electrical appliances provide against mechanical impacts from outside. It is defined by standard IEC 62262. The degree of mechanical protection is identified by a code that consists of the letters IK followed by two digits:

Some Network cameras have CVBS analog video output port so it can be seen through a portable monitor.
It is utilized for making the image more focused and setting view angle.
When the camera operates in IDIS protocol, Video format between NTSC and PAL is selectable in Setup > Video > Camera > Miscellaneous.

In the case of WDR camera,
There is a condition to output the analog signal. CVBS analog video signal might not be generated from the camera. It’s a limitation of the SoC chip on the WDR camera.
If the 4th stream is not set (only 3 streams are operating), CVBS will perform well.
In DirectIP NVR, if the custom field for recording is not set, CVBS will be outputted.

To receive stream via RTSP(Real Time Streaming Protocol), RTSP player is required.

VLC player is one of the most popular players.(http://www.videolan.org/)

The command line for playing remote live video via RTSP is below.

Please refer to the capture below for an example.

850nm Infrared-ray is illuminated from the IR-LED.

In general, humanity can see wavelength up to 780nm (visible light wavelength: 380nm ~ 780nm)

Normally, when a camera uses infrared LED arrays for wide-area illumination at night, you may see the overexposure image when the object is closed to the IR camera.
Smart IR technology automatically adjusts IR intensity according to proximity and eliminates object overexposure caused by strong illumination. Smart IR is useful to identify a person’s face or an object movement at night.

If you wish to connect DirectIP cameras to non-DirectIP NVR or VMS, you should change the DirectIP camera’s protocol to ONVIF protocol using our INIT (Integrated Network Installation Tool) software. If the cameras are rebooted after the protocol change, the DirectIP camera will operate as an ONVIF camera.

Many DirectIP cameras have spot output. By spot output, the image can be seen during the installation in the NTSC/PAL D1 resolution. But, some cameras do not support spot output. So, you should check whether your cameras support spot output or not.
Spot output ports are broken into two types - RCA and terminal block. If you want to use spot output, you should check the spot output port type of your camera.
Spot output on DC-X1XXX series camera works until the camera is registered to a DirectIP NVR.

Some DirectIP cameras have built-in alarm in/out ports. Normally, alarm input has TTL voltage level and NC/NO programmable. Alarm output only supports the NO mode with relay output. Regarding the alarm in/out specifications, you can connect your alarm devices such as a smoke sensor or fire alarm to the alarm in/out port on the DirectIP camera.
DirectIP NVRs can set and use the each DirectIP camera’s alarm in/out ports as well as NVR’s alarm in/out ports.
For using an alarm input device connected to DirectIP, you should select [Setup]-[Event]-[Alarm-In] menu sequentially. Then you can select the alarm input device connected in DirectIP as event signal channel.
For using an alarm output device connected to DirectIP, you should select [Setup]-[Device]-[Alarm-Out] menu sequentially, Then you can select the alarm output device connected to DirectIP as alarm output channel.
Using the above setup configuration, you can use external alarm devices directly wired to the camera input which will be seen by the system as if it were connected to the NVR directly.

DirectIP cameras can be configured by IDIS Discovery software and DirectIP NVRs. Our software helps to find and configure your camera fast and easy. If DirectIP cameras are connected to DirectIP NVRs, you can easily configure multiple DirectIP cameras on NVR’s setup menu. If you set multiple camera configurations on NVR, all changed parameters will be passed to each DirectIP camera immediately.

No. DirectIP cameras have no OSD menu. So, you should configure the DirectIP using IDIS NVR, IDIS Solution Suite, IDIS Center, or IDIS Discovery software.

It’s difficult to get the same level of performance with 3rd party cameras. Generally, concerning transmitting video streams to DirectIP NVRs, 3rd party cameras have lower performance than DirectIP cameras. That is because DirectIP protocol has specific multiple stream channels and their video profile and frame rate adjustment technology to satisfy optimal performance of video data transmission for live monitoring, recording, playing, and remote transmitting. So, if you connect 3rd party cameras with IDIS NVRs, the benefits of DirectIP protocols disappear.

IRE stands for Insitute of Radio Engineers and represents the composite video signal in percentage terms. That is, 100 IRE equals 100% full signal level which means 714mV amplitude active video signal.
Generally, 30 IRE is a minimum value for a detailed and acceptable image.
Most cameras represent the lux level that the maximum amplitude of the video signal is 30% or 50% of the original amplitude.

ICR

ICR (Infrared Cut Filter) is used with color CCD or CMOS image sensors to produce accurate color images. During the day, the camera uses an ICR to reflect or block mid-infrared wavelengths while passing visible lights. However, as light diminishes below a certain level, some cameras can automatically turn off ICR functionality to deliver high-quality, black and white image using infrared light.

TDN

TDN (True Day/Night) technology supports night vision capability by implementing a physical ICR that is removed by a mechanical motor.

DDN

DDN (Digital Day/Night) technology allows for viewing in both day and night conditions, without the use of an ICR. As light diminishes below a certain level, DDN technology switches color image to black and white image to offer similar benefits to TDN at a lower cost. At night, the captured image depends on the lighting and infrared waves off objects.
