“The stream is encrypted. Please go to the Local Configuration interface to set the Encryption Key and restart live view.”
Seen as a pop-up in the bottom right hand corner of your screen, when trying to access the video streams from HikVision cameras on Live View.
Navigate to Configuration –> Advanced Settings –> and set the encryption key (verification code).
The ‘key’ that you need to enter is actually the “Verification Code” that you set when you enabled and set up the Platform Access for Hik-Connect.
i.e. the Verification code that you entered here:
You need to enter this verification code / encryption key via the web browser of any PC (even on the same LAN) that you wish to access the NVR from.
You will need to enter the code / key here:
You then need to disable encrypted streaming on the recorder itself.
This can only be done (enabled/disabled) via a monitor directly connected to your NVR.
You will need to navigate to Configuration –> Network –> Access Platform and un-tick “Enable Stream Encryption”.
You should now be able to see the “live view” in your web browser.
(1) False alarm filter
Go to NVR’s local GUI, System—Event—Smart Event, choose and enable the event you want to detect, then check target of interest. You can choose between 3 modes: Human, Vehicle or Human& Vehicle. Once you enable the option(s), it will based on the algorithm to filter most of the false alarm.
If you tick ‘Enable Smart Analysis’, NVR will detect event with NVR algorithm and no IP camera smart detection needed. Thus NVR is able to detect smart event even if IP camera doesn’t support. This mode has a higher accuracy and is recommended when there’s massive false alarms from IP cameras. Please notice NVR only support 1x Line crossing and 1x Intrusion Detection in this mode at present. In addition, IP camera’s video stream should be standard H264 or H265, resolution should be lower than or equal to 8MP. In addition, the resolution of camera must be between 2MP to 8MP.
After alarm is filtered, NVR normal playback and file management can only search right alarms, if you want to search false alarms, please go to ‘File Management—Event Type—False Alarm’.
2. Scene and Rule
In order to make the whole system more accurate, there’re some mounting and rule requirements for IP cameras.
In this chapter, we take several typical scenarios as examples to help you setup a better perimeter system.
- IP camera installation
Camera is recommended to be installed 2-3 meters high. If it is installed outside, it should be 3-8m high.
The monitoring distance is recommended to be within 50 meters, estimated longest distance for different focal length: 6mm, 30M; 8mm, 40M; 12mm, 50M. This is just a reference, it varies in different scenarios.
Angle between the optic axis and the horizontal line should be larger than 15°.
- Target size
DeepinMind NVR can analyze target whose height is between 1/16 and 1/2 of the image vertical size. For instance, IP camera resolution is 1080P, target vertical size should be larger than 64 pixels and smaller than 540 pixels.
For example, the target in picture below is too large to detect, the man almost covers the whole scene. We suggest adjusting the angle higher so that IP camera can start detecing from a longer distance.
It’s easy to deduce that once the scene is too dark, IP camera or NVR can’t detect target exactly. Lighting supplement or low light cameras is recommended in scene below.
If there’re obstacles in front of the camera, there will be c false alarms which occupy NVR smart resources. In addition, large obstacle might block target you are really interested in. Scene in picture below is not an appropriate one for detecting.
- Strong light
In some scenarios, strong light interference makes a target hard to be detected. Strong light generally can be divided into two kinds: strong background light and strong foreground light.
Strong background light makes foreground target totally dark, as what is shown picture below, the man in corridor looks like a shadow. WDR or BLC function is recommended in this scene.
Strong foreground light is usually generated by sudden light intensity change such as car light, flash light, sunshine reflection. We suggest customer change IP camera’s angle to avoid strong light or use cameras with HLC function.
- Complex scene
We suggest customer use perimeter guarding alarm to detect human who is not supposed to enter a region or cross a line, so it’s not applicable in a scenario such as train station with large people flow.
The scene below has too many people and create a vast number of alarms, it’s not a recommended scene for detection.
- Detection rule
In addition to installation guide, appropriate rule is also a critical part in perimeter guarding system.
Here’s an example, customer wants to detect man who walk across the door on the left side. However, the rule is too near to the edge. Once a man appears in the scene, there’s no enough time for NVR or IP camera to detect. We highly recommended customer set detection rule in the center of the scene, or not near the scene’s edge.
- Rule position
Although DeepinMind NVR is able to filter false alarms created by leaves, animals etc, it is highly recommended to set rule in a static field/ object. One customer set line crossing rule on grass in scene below, grass continuously makes false alarms which occupy NVR smart resource and storage space.
- IP camera selection
If customer wants
to use smart detection in an indoor
environment, IP camera
with WDR and wide FOV is recommended.
In some outdoor scenarios, bullet camera are a better choice than dome camera. Some raindrops might be stuck to the surface of dome camera, with raindrops accumulated, it decreases accuracy of smart detection.
Here’re several modes we recommend for outdoor/indoor use, customer can also select by themselves according to actual scenario.
|2 series||DS-2CD21x5 series DS-2CD23x5 series||DS-2CD2Tx5 series DS-2CD26x5 series|
|4 series||DS-2CD4Cx6 series DS-2CD4Dx6 series||DS-2CD4Bx6 series DS-2CD4Dx6 series|
It is recommended to let the AcuSense camera do the false alarm reduction. This will save the AcuSense NVR resources for normal IPC. Please make sure this camera channel has ‘Enable Local Smart Analysis’ unticked.
1) Go to NVR’s web page, Configuration—Event—Smart Event, choose AcuSense camera channel.
2) Choose and enable event that you want to detect (line crossing, region intrusion, region entrance detection or region exiting detection), draw rules.
3) Choose detection target(s). There are three choices: Human, Vehicle or Human& Vehicle. Then click save. Once the detection target is enabled, AcuSense Camera will filter false alarms based on the algorithm automatically.
NVR FW is V4.20 or above, configurations are just the same as AcuSense camera+ AcuSense NVR
If NVR FW is V4.1xx,
1) Go to NVR’s web page, Configuration—Event—Smart Event, choose the AcuSense IPC channel.
2) Choose and enable event that you want to detect (line crossing, region intrusion, region entrance detection or region exiting detection), draw rules;
3) Go to IPC’s web page, check the target of interest. You can choose between 3 modes: Human, Vehicle or Human & Vehicle. Once the target detection is enabled, the IPC will filter most of the false alarms based on the algorithm automatically.
Using a Hikvision NVR’s “Virtual Host” Feature
One of the most successful selling points of a Hikvision NVR to many small-setup customers is the “Plug and Play” functionality that simplifies the setup process of their surveillance system. However, plugging a camera directly into a port on the NVR unfortunately does not allow you to access the camera via its own internal LAN IP using a browser due to it being on the NVRs internal network, and this can significantly reduce the amount of configuration options you have access to. The NVR does allow you to configure many options for each connected camera, but some essential features are only accessible via connecting to the camera itself (such as audio codec options). This was of course a big problem previously.
With the advent of newer firmware and models of NVR, Hikvision have introduced a feature called Virtual Host. Activating this feature turns your NVR into a “host” for the cameras allowing you to connect to them via a browser. Essentially, the NVR forwards all traffic received from your browser to the appropriate camera you’re trying to connect to, eliminating the biggest problem of plug and play functionality.
Note: Whilst Hikvision are working to update existing models of NVR to enable this feature, not all of them will currently have Virtual Host functionality. We recommend checking online and updating your firmware to see whether your model is compatible.
First of all, access your NVR via a web browser. If you do not know the LAN IP of your NVR, download Hikvision’s tool SADP here. It scans your network for any Hikvision devices that are connected and allows you to see and/or change their network settings, including the internal IP.
Once you’ve logged in, navigate to Configuration –> System –> Camera Management
This screen displays all the connected cameras on your NVR. Notice that the final column labelled “Connect” is currently empty. We’ll be coming back here in a moment.
Now, navigate to Network –> Advanced Settings –> Other tab and make sure you tick the option “Enable Virtual Host”
NB – when you click ‘Save’ your NVR will reboot.
Now, navigate back to the Camera Management window from
earlier. You’ll notice that the previously empty connect tab now
features links for each camera currently connected to your NVR.
Simply click on any of these links to access the respective camera via your web browser.
Https protocol is Hyper Text Transfer Protocol over Secure Socket Layer. With this protocol,the data transmitted can be encrypted to enhance security level. Hikvision products provide self-signed certificate, which means user can use free Https certificate in local area network. Besides, user can install signed certificate or create certificate request .
This article shows how to configure Https protocol in 3 ways.
1 Self-signed certificate
Self-signed certificate is Hikvision’s private certificate which provides user with secure link to access to device. It’s highly recommended to be used in local area network. Access to the webpage of device (NVR is the sample device in this article), go to
Choose Create Self-signed certificate and click create, input the basic information and click ok.
Check Enable and click Save, a self-signed certificate will be installed into the device.
The address format of https is https://IPaddress:Port, notice that all self-signed certificate will pop out below hint, click Continue to this website.
2 Create certificate request
Hikvision products supports quick-export certificate request, you can upload this request to some official certificate authorities.
Click Create, input basic information of certificate, notice that fixed public IP address or domain name is required as Hostname/IP. Notice: Don’t input request password for NVR which runs an older firmware version than V3.4.62.
After creating request, download it to PC. This request could be used to apply for official https certificate.
3 Install signed certificate
After certificate is signed by official authority, user can install it to the device. Notice that the public IP address or domain name must match the device’s actual IP address. User can access to device with https link in public network.
Notice: (1) Only PEM format certificate is supported; (2) NVR can only recognize the certificate which is generated basing on the request exported by itself; (3) A new signature is required when user re-uploads the certificate.
