FAQ

A. Yes. We recommend using same capacity HDDs in 1 eSATA storage.

Even if the HDDs have different capacities, eSATA works. However, if user sets RAID, the total capacity is calculated based on low capacity.

It means, User cannot use as much as the difference in capacity between two HDDs.

Also, using HDDs with different sizes increases the number of caese in problem, making it difficult to provice technical support.

A. For example, assuming that the height of detected object as human is 1.7m.

The distance by level is as follows.

Level 1 : 0.7m

Level 2 : 1.4m

Level 3 : 2m

Level 4 : 2.7m

Level 5 : 3.4m

A. User can change the IP address if the DV-1304 have never registered to the NVR before.

If user wants to change it, please do factory reset and then change the IP address.

To support DIP 1.0 cameras, here are supported functions in INIT

1. Setup : IP address setup

2. Reset : Soft, Factory

3. Management : Upgrade, System log

A. There is no specific limitation, Our LAB tested registration upto 4000 NVRs.

A. The IDIS Center manages device names if the Device Name Sync is unticked.

In this case, even if user changes the device name, IDIS Center shows the existing device name.

"Setup > Double Click the Device > Edit Device > Tick/Untick Device Name Sync"

1. Frame mode : It is a "Multi-Exposure Control" synthesis method.

It is to generate 1 image by synthesizing image information taken by Short Exposure and Long Exposure

2. Line mode : It is a method of ouputting data of 3 frames with different exposure times in line via the Line Buffer of the ISP.

It allows to maintain frame rate and initialize overlapping problems betwwen frames.

A. The ADC key value entered by OSD button is read by VD Sync.

In addition, to prevent malfunction due to noise, it is operated when the input value is maintained at least 2 frames.

Thus, 12.5fps has a long interval VD Sync so, it works relateively slowly,

A. The debug information is extracted based on the time of extraction.

After first export, based on the existing file, only the new debug is extracted.

Therefore, if there is no new information, it will have same size. On the contrary, if there is new, it extract new information only.

A. It is used for seamless communication even in low bandwith network.

However,, if "Device Low Bandwidth Communication" is enabled, it is not effective in the normal network because it trys handshake communication between the device and client.

A. No. DV-1304(-A) has compatible with only IDIS Camera, not Onvif Camera.

A. Intelligent TLS is a level similar to TLS Very High level (Exclude Multimedia SSL).
General Exclude Multimedia SSL is used in Windows, and since it requires significant additional performance, ISS performance may be greatly reduced.
To solve this, SSL/TLS was applied according to our protocol to improve processing speed so as not to affect performance.
 

A. 

1. Online Mode : Initial access to the License Server once, then no need to connect it. After Verificatioin the License Key, internet is not required.

2. Offline Mode :  Input the key without Internet.

3. Cloud Mode : It has to keep opening internet access, because Admin service keeps connection to the license server every day. limited time is 24 hours. If the network is disconnected and flows without recover it, ISS services goes out (Status : Demo Expired) if the ISS service restarts. 

A. Please refer to the image.

Other bullet camera also has factory reset button inside.

A. In general set up should be done on 3 sides to use a network keyboard.

1. Keyboard local side: Register server 
2. ISS setup side: Register a network keyboard at Device tab
3. ISS Client setup side: Turn on 'Use Network Keyboard' option

A. CGNAT means Carrier-grade NAT and this is used a solution for IP address exhaustion. Lots of Internet Service Providers(ISP) implementing this device in there network infrastructure.
This could impact on the stability of FEN connection on your client devices. In this case, call local ISP and ask them opt-out from CGNAT pool.
