36 Camera Q. How to apply privacy masks on an IP camera 2015-07-06
A.

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.

35 Camera Q. How to upgrade IP camera's firmware 2015-07-06
A.

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.

34 Camera Q. What is the IK rating? 2015-07-06
A.

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:

33 Camera Q. How to display an analog video (CVBS) output of an IP camera? 2015-07-06
A.

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.

32 Camera Q. RTSP stream commands of IDIS IP cameras 2015-07-06
A.

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.

rtsp://ID:Password@IPaddress:RTSP port number/trackID=‘channel number

 

Please refer to the capture below for an example.

 
31 Camera Q. Which infrared-ray wavelength is used with IR Camera? 2015-07-06
A.

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

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

30 General Q. How can IDIS device detect the audio input event? 2015-07-06
A.

For audio detection, the device (ex. DirectIP camera) calculates the average power of the audio signal that is transmitted for a specific time (6.5 seconds).
If the current audio signal’s power is much higher than the power threshold of the audio signal (based on the average power of the audio signal), then audio detection is enabled.
That is,
1. Gather audio signal for 6.5 seconds
2. Calculate the average power of the audio signal
3. Compare the current power of the audio signal with the power threshold of the audio signal
4. Decide whether audio is detected or not.
 
The threshold of power level is determined by the audio sensitivity level.
* Sensitivity level 1: two times (6dB) higher than the average power of the audio signal
……..
* Sensitivity level 5: 1.2 times (1.6dB) higher than the average power of the audio signal

29 General Q. How to check the current external IP address 2015-07-06
A.

External IP address means the IP address on the public internet side. Commonly our PC might have the internal IP address range which is assigned from gateway such as NAT(Network address translation).

NAT helps us to use one public internet IP over many network devices.

 

The reason that you have to check the external IP address is that it is needed to connect the NVR or camera from the internet. The client uses the external IP to reach the target.

 

You can check the external IP address if you visit the following sites.

28 General Q. What is DDNS? 2015-07-06
A.

DDNS is Dynamic DNS(Domain Name System).
ISP(Internet Service Provider) is changing periodically an IP address to use limited IP range effectively.
To maintain the connectivity with the server anytime, the client has to know the IP address of the server.
But it’s not easy to track the IP address which is being changed constantly.
Therefore, DDNS is needed.

DDNS always tracks and keeps the available IP address of the server. When the client inquires the information to connect the server, DDNS service responds to a request. So that the client can connect to the server correctly with the connection information.

27 General Q. How do I make a Cat5, Cat5e or Cat6 patch or crossover cable? 2015-07-02
A.

To minimize packet loss, the wiring has to be aligned exactly according to the standard.
The ordinary alignment is called 568A and 568B. It was established by TIA(Telecommunications Industry Association)/EIA(Electronic Industries Alliance).
Cable alignment 568A and 568B are below.

Pin

T568B Color

If both end patches are assembled as T568B, the cable can be used for ordinary LAN cable for CAT5, CAT5e, CAT6.

In case of a crossover cable, one of patch cords shall be a type of T568A, another one shall be a type of T568B. Nowadays most ethernet adaptors support to recognize the type of connector between T568A and T568B.

 

 
26 Video Recorder Q. Can I use other brand's network camera with IDIS NVR? And, which kind of cameras is supported? 2015-03-24
A.

Yes. Our NVRs support the Axis, Panasonic, and OnVIF network protocols for other brands' network cameras. So if your camera has one of the protocols mentioned above, it can be used with our NVRs though the performance is not as good as the DirectIP cameras. Of course, our non-DirectIP network cameras can connect with our NVRs.

25 Camera Q. What is Smart IR? 2015-03-23
A.

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.

24 Camera Q. Can I use DirectIP cameras with other 3rd party NVRs? like Milestone? 2015-03-23
A.

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.

23 Camera Q. Do DirectIP cameras have spot output? 2015-03-23
A.

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.
