145 General Q. How can I change protocol in DirectIP 2.0 mode ? 2019-11-08

The existing DirectIP 1.0 protocol has two modes, DirectIP mode and IDIS mode. You have to reboot the camera to change each mode.
DirectIP 2.0 protocol is a unified form of two modes. Without rebooting, the protocol can take advantage of all the advantages of DirectIP mode and IDIS mode.

In DirectIP 2.0, a camera boots up as a DHCP client looking for a DHCP server for about 40 seconds. Once no DHCP server is found, it starts to have a link local IP address.


144 Video Recorder Q. Do NVRs support IPv6? 2019-11-08

You can use WAN as IPv6 from the version of NVR below. (As of March 2019)
 IPv6 becomes available by selecting IPv6 in 'Settings-Network-WAN'.
 * IPv6 can be used only in the WAN used for remote access and cannot be set in VIN (Video IN) to register the camera.


- IPv6 supporting NVR models

   DR-1304P, DR-1308P, DR-2304P, DR-2308P, DR-4316PS, DR-6216PS, DR-6332PS, DR-8364


- Firmware version 

   v6.1.0 or higher


143 Camera Q. Is it possible to connect DirectIP 2.0 protocol cameras to DR-2100/4100/6100 which only supports DirectIP 1.0 protocol? 2019-11-08

Possible. The way to register them to the NVRs is the same as registering a camera in DirectIP 1.0 protocol.

142 Camera Q. What is Auto Tracking and which camera models support the feature ? 2018-09-06
Auto Tracking is a feature tracing movements made by objects such as human or vehicles.
Without manual control by a human, a camera automatically finds movements using PTZ. 
The feature is mostly used for restricted area where movement is rarely expected. 

Supporting camera models
- DC-S3283WHX
- DC-S3283FX
- DC-S3583HRX
- DC-S3883HRX

141 Camera Q. How to make a audio connection to IDIS cameras 2018-09-06

How to make a audio connection to IDIS cameras

H.265 supporting camera models

rtsp://"IP address: Port number"/media/trackID=90

For example, rtsp://


H.264 supporting camera models

rtsp://"IP address:Port number"/trackID="maximum number stream+1"

For example, a camera can have 3 streams "trackID" is 3, and the URL will be rtsp://

140 Software Q. What are the QR codes in NVRs for? 2018-09-06

QR codes in IDIS NVRs save time to type in an IP address or a FEN name of an IDIS NVR, when registering the NVR to IDIS Mobile.


- In IDIS Mobile, when registering a site, click QA icon on the right bottom.


- Camera is going to run to capture a QR code.

- Capture a QR code in an IDIS NVR.

- Either IP address or FEN name of the NVR will be filled out in IDIS mobile already, and give a name for the NVR and a right password to finish the registration.


Simple registration using QR codes is available for registrations with both FEN and IP address.




139 Camera Q. What to check if IR LEDs don't look working. 2018-09-06
1) Turn off all the lights around a camera
- Check if the camera changes into Night Mode. 

2) Check settings of a camera
- Related settings are in Day&Night tab in Camera menu under Video in Remote Setup.
- Check if B&W mode is set either On or Off and not switching.
- Check if B&W mode switching schedule is configured correctly.
- Check if Switching Level is set as desired.
138 Accessory Q. How to do Factory reset network keyboards ? 2018-07-30

With IDIS Discovery

Run IDIS Discovery which is our device scanning utility.

Click a network keyboard and click Factory reset as the below image shows.





Reset button

Press and hold Reset button on the bottom panel for about 3 second. 

The network keyboard will automatically reboot. 


137 Accessory Q. PoE output capacity of DA-LP1101T/R 2018-07-30

DA-LP1101T/R has Long Reach PoE function and PoE output capacity becomes different when the function is enabled or when it is not.


In use of Long Reach PoE function

Please be aware that bandwidth of DA-LP1101R/T is decreased to 10/100Mbps in use of Long Reach PoE function.



Not in use of Long Reach PoE function

*The value may change depending on the power, cable and PoE device you use.



This specification is included in the manual page 6 to 7.


136 Video Recorder Q. Recorders don't have power switch. Is there anyway to turn off the recorders ? 2018-07-17

Only way to turn off/on the recorders is to plug in/out power cable. 

The recorders don't have power switch or a UI on their software to power off. This is to remove a possibility that users accidentally press power switch off or click a power off button, resulting in a recording service halt.


135 Video Recorder Q. How can I find password lost? 2018-07-12

A Password is created and encrypted so we cannot tell you what password it was.


We strongly recommend you to either configure SMTP to get verification code or keep User Password Reset File in a USB stick for creating a new password on the initial login.


"Find PW" feature is described in detail in the manuals of DR-8300, 6300, 4300 and 2300 series.

134 Video Recorder Q. Which data will be removed by Factory reset ? 2018-07-09

All the configuration including Network, Time, Event, Camera setup and even password will be removed and back to default status. This goes for TVI recorders as well.

However, recorded data will remain as it was before the factory reset. To remove recorded data, "Clear All Data..." on General menu of System needs to be executed. 



133 Camera Q. A lens does not work on a box camera. 2018-07-09

For P-IRIS lenses, since the method of operation differs from each product, it has to use the tested P-IRIS lens with the camera.

For DC-IRIS lenses, all the lenses are compatible.


The list of recommended P-IRIS lens are as follow.


- DC-B1203X : DC-IRIS lenses support only.

- DC-B3303X :

  • M13VP288IR
  • M13VP850IR

- DC-B1303 :

  • EVETAR M117VP451016
  • RICOM HV03610P

132 Camera Q. Can I use DC-T1244WR for both license plate recognition and for surveillance purpose? 2018-07-09

It cannot use for both purposes simultaneously


Each good image quality for ANPR and for surveillance is defined differently as below, so we don't recommend to use the camera for both purposes.


please refer to below and its hard to control the image for surveillance via ANPR IP Camera.


"Good quality" image in general video surveillance.

- Wide dynamic range, deep depth of field, crisp image detail, good color saturation, anti-flickering, minimal motion blur, low noise, and hundreds of other criteria.


"Good quality" image in ANPR application.

- Best exposure.

- Tighter iris control if possible to achieve deeper depth of field.

- Shortest shutter speed to minimize the motion blur.

- Black and White for better license plate capture : even though there are enough ambient lights and even though you sacrifice the color information.

- Gain control to minimize the noise

131 Video Recorder Q. Connecting PoE switches to DR-8364 2018-07-06

A DR-8364 series NVR has video input ports which consists of two SFP ports and three RJ45 ports.


Not to place too much load on one RJ45 port, please distribute channels onto switches and connect each switch to each different RJ45 port as the image below shows.



Be aware of that connecting more than one RJ45 port to a same switch can create packet loop, so please separate links from each port.
