Access your Hikvision NVR or Camera on Android devices

How to access your HikVision NVR or Camera on Android devices 

Closed-circuit television (CCTV), also known as video surveillance, is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point-to-point (P2P), point-to-multipoint (P2MP), or mesh wired or wireless links but transmit a signal to a specific place only. Not for open to all. This article I write just for HikVision Lover only. Personally I am not support to install Hikvision/Dahua product or OEMN product. Technically 100% unsafe your personal video data.

Day by Day increase hacking of video surveillance camera. Now cyberattacks on CCTV systems making news headlines on a weekly basis of late, there is a good deal of concern and uncertainty about how at risk these systems are, as well as why they are being attacked.

In 2014, a US ally observed a malicious actor attacking the US State Department computer systems. In response the NSA traced the attacker’s source and infiltrated their computer systems gaining access to their CCTV cameras from where they were able to observe the hackers’ comings and goings.

In October 2016, 600,000 internet connected cameras, DVR’s, routers and other IoT devices were compromised and used to for a massive Bot Net to launch what was the largest Denial of Service (DOS) attack the internet had experienced to date.

In the lead up to the 2017 US Presidential inauguration, 65 per cent of the recording servers for the city of Washington CCTV system were infected with ransomware. How did the attack take place? Whilst unknown, it most likely occurred by the same means as other common PC hacks such as infected USB keys, malicious web sites, or phishing attacks.

May, 2018, over 60 Canon cameras in Japan were hacked with “I’m Hacked. bye2” appearing in the camera display text. How did the attack take place? Simple. IP cameras were connected to the internet and were left on default credentials. It appears that the hackers logged into the cameras and changed the on-screen display. What was the impact? Other the defacement of the camera displays and some reputational damage, there doesn’t seem to have been much impact from these attacks.

On Aug 13, 2018, The US President has signed the 2019 NDAA into law, banning the use of Dahua and HikVision (and their OEMs) for the US government, for US government-funded contracts and possibly for 'critical infrastructure' and 'national Security’ usage.

US government is effectively blacklisting Dahua and HikVision products, this will have a severe branding and consequentially purchasing impact. Many buyers will be concerned about:

What security risks those products pose for them

What problems might occur if they want to integrate with public / government systems

What future legislation at the state or local level might ban usage of such systems

On Jun 06, 2019 Hanwha Techwin is dropping Huawei Hisilicon from all of their products. Its belongs to China’s origin. Backdoor entry is open on product.

China's Wuhan Institute of Virology, the lab at the core of coronavirus. The institute is home to the China Centre for Virus Culture Collection, the largest virus bank in Asia which preserves more than 1,500 strains ( https://www.livemint.com/news/world/china-s-wuhan-institute-of-virology-the-lab-at-the-core-of-a-virus-controversy-11587266870143.html ). Result Corona has infected people in 185 countries. Its spread has left businesses around the world counting the costs. Global economy impact. Recession increase. Now people avoid to get china factory made product, electronics goods importing has stopped from china to other country. People looking for product except china. Now come to Video surveillance, access control equipment.

The ban that prohibits the purchase and installation of video surveillance equipment from Hikvision, Dahua and Hytera Communications in federal installations – passed on year 2018 National Defense Authorization Act (NDAA). In conjunction with the ban’s implementation, the government has also published a Federal Acquisition Regulation (FAR) that outlines interim rules for how it will be applied moving forward. Like NFPA, now NDAA law accept globally.

Rules outlined in this FAR include:

  • A “solicitation provision” that requires government contractors to declare whether a bid includes covered equipment under the act;
  • Defines covered equipment to include commercial items, including commercially available off-the-shelf (COTS) items, which the rule says, “may have a significant economic impact on a substantial number of small entities;”
  • Requires government procurement officers to modify indefinite delivery contracts to include the FAR clause for future orders;
  • Extends the ban to contracts at or below both the Micro-Purchase Threshold ($10,000) and Simplified Acquisition Threshold ($250,000), which typically gives agencies the ability to make purchases without federal acquisition rules applying.
  • Prohibits the purchase and installation of equipment from Chinese telecom giants Huawei and ZTE Corporation. This would also presumably extend to Huawei subsidiary Hisilicon, whose chips are found in many network cameras;
  • And, gives executive agency heads the ability grant a one-time waiver on a case-by-case basis for up to a two-year period.

Specifically, NDAA Section 889 creates a general prohibition on telecommunications or video surveillance equipment or services produced or provided by the following companies (and associated subsidiaries or affiliates):

  • Huawei Technologies Company; or
  • ZTE Corporation

It also prohibits equipment or services used specifically for national security purposes, such as public safety or security of government facilities, provided by the following companies (and associated subsidiaries or affiliates):

  • Hytera Communications Corporation;
  • Hangzhou Hikvision Digital Technology Company; or
  • Dahua Technology Company

While the prohibitions are initially limited to the five named companies, Section 889 authorizes the Secretary of Defense, in consultation with the Director of National Intelligence or the Director of the FBI, to extend these restrictions to additional companies based on their relationships to the Chinese Government. The prohibitions will take effect for executive-branch agencies on August 13, 2019, one year after the date of the enactment of the 2019 NDAA, and will extend to beneficiaries of any grants, loans, or subsidies from such agencies after an additional year.

The provisions of Section 889 are quite broad, and key concepts are left undefined, such as how the Secretary of Defense is to determine what constitutes an entity that is “owned or controlled by, or otherwise connected to” a covered foreign country, or how the head of an agency should determine whether a component is “substantial,” “essential,” or “critical” to the system of which it is part. The statute also fails to address the application of the prohibitions to equipment produced by U.S. manufacturers that incorporate elements supplied by the covered entities as original equipment manufacturers (“OEMs”) or other kinds of supplier relationships.

Section 889 contains two exceptions under which its prohibitions do not apply:

(1) It allows Executive agencies to procure services that connect to the facilities of a third party, “such as backhaul, roaming, or interconnection arrangements.” This likely means telecommunications providers are permitted to maintain common network arrangements with the covered entities.

(2) It permits covered telecommunications equipment that is unable to “route or redirect user data traffic or permit visibility into any user data or packets” it might handle, meaning a contractor may still be able to provide services to the Government so long as any covered equipment provided is unable to interact or access the data it handles.

Now we come to short process. First of all we need to find the IP address of the Hikvision device we want to connect too. First of all download SADP. This program will scan your network for Hikvision devices connected on your network.

Older Hikvision devices are shipped with a static IP address of 192.64.0.0, whereas new devices are shipped with DHCP enabled which means they will automatically be assigned an IP address that corresponds to your local network. If you're camera is set to a static IP address you will need to find out what range it needs to be changed to. To find out your local IP address follow the steps below.

  1. click start > control panel
  2. click network and internet
  3. Click network sharing center
  4. click Local area Connection
  5. Look at your IPv4 Default Gateway, it is usually either 192.168.1.1 or 192.168.0.1, however it can differ.

Once you know the default gateway you can set a new IP address for your device. You only want to change the last three digits of the IP address. I would recommend starting the last three digits at 100, so you don't conflict with anything else on your network such as a printer or phone.

If you're not responsible for your network, make sure to check with your IT department or administrators that the IP address isn't already taken.

An example of a set IP address would be 192.168.1.100.

Once you know what IP address to set your device too, you will need the password of the device to set it.
By default the password is 12345 for Hikvision devices.

For a quick overview of what you should see in SADP, check the image below. In the example the IP address is 192.168.1.212, this is because we have a variety of different cameras and devices on our network.

Once all this is set up, your cameras or NVR will be properly configured with your Local Network. You should be able to go into your browser and type in the IP address of the camera/NVR, and it will come up with a log in page.

Getting everything to work in the app


First of all, head on to the play store, as you need to install the iVMS4500 android app. Once you have downloaded the app, go ahead and launch it.

The first time you start up the app you will have to go through a small tutorial, which will show you a variety of cameras in china. Once the tutorial is over, tap the menu tab in the top right corner of the app and then tap the devices tab. from here there will be a plus sign in the top right hand corner. Tap this to add your Hikvision Device.

When you click the plus button you will see the following screen (Minus some information I have already entered) I will explain the options further below.

Alias - what you want to call the device you're adding. Useful for organisation. The alias is exclusive to the app, and doesn't change any actual camera settings.

Register mode - Set this to IP/Domain to add the device via it's IP address properly.

Address - The IP address of the device goes here

Port - usually leave this the same.

Username - admin
Password - 12345

Camera no. - Ignore this part, it will change depending on what device you are adding.

Tap the floppy Disk Icon to save the device.

Now go back, you will return to the devices tab. Uncheck the "Hangzhou, China" device, and check the device you added. From here click live view and you are ready to view your cameras on your local network.

From this point onwards, you will be able to view your Hikvision device on your android device, as long as you are on the same network.

Port-Forwarding, and accessing your devices from anywhere

If you want to access your cameras, or NVR remotely (From anywhere) You will need to have the devices port-forwarded. Port-forwarding is different for each router, but the ports that must be opened remain the same. For more information on Port-Forwarding, and a guide on how to set up your specific router, please head tohttp://portforward.com/.

When port forwarding a Hikvision camera, the ports that should be opened are

Port 80 - HTTP Protocol
Port 8000 - Client Software Port
Port 554 - RTSP Port
Port 1024 - 3G/4G Port, for access via a 3G or 4G mobile connection

Once you have successfully port forwarded your Hikvision device, follow the steps above, relevant to the OS you're using, and then insert the port-forwarded address of the device where the IP option goes.

This view may be slightly choppier, it depends on the speed of your current internet connection.

Q. What is the driving issue behind the National Defense Authorization Act (NDAA),
formerly known as HR5515?
A.     Cybersecurity concerns. In particular, cybersecurity of telecommunications and video surveillance products from specific companies that have deep relationships with a “covered foreign country” government, the People’s Republic of China.

Q.The named companies that are banned by the NDAA are based in China. Does the NDAA ban all video surveillance and telecommunications products and components made in China?
A: No. The NDAA does not ban all products and components that are designed or manufactured in China.
As per NDAA Section 889, f – definitions, 3 – Covered Telecommunications [and Video Surveillance] Equipment or Services, items A through D calls out specifically-named companies “that the Secretary of Defense, in consultation with the Director of the National Intelligence or the Director of the Federal Bureau of Investigation, believes to be an entity owned or controlled by, or otherwise connected to, the government of a covered foreign country [The People’s Republic of China]”.
Hence, the NDAA does not ban products manufactured in China by companies that are headquartered and owned by entities that are not based in China.

P2P Networking – the fast way to connect camera

A Peer to Peer network (often shortened to P2P) is a connection process where two or more IP Camera / DVR/ NVR / PCs connected to each other can share resources , peripherals as equals  without the need of a central dedicated server.

It is a distributed application architecture that divides tasks / workloads among Peers. Peers refer to the workstations connected to the P2P network which are participants in the application and which are all equally able to perform any function necessary for the network. A computer connected to this network is called a node.


The reason for the popularity of a P2P network is that it can be set up anywhere- Homes, offices, online business etc. The only requirement is that all the participants of the network should be using the same or a compatible program, (client), to connect to each other.

The first P2P app was Napster, released in 1999.

Basic overview
In a P2P network each node is essentially a client as well as a server, thereby eliminating the need for special high performance machines to act as servers. Accessing files is basically governed by the user setting different sharing permissions on their own machines.

Advantages
Due to the inherent characteristic of P2P networks it is the clients who are responsible for providing network resources such as bandwidth, system power, and storage. This feature is tremendously useful to original content distributors, because it reduces the setup as well as running costs very small.

Due to the decentralized nature of the network, if one peer  ceases to function properly, it does not affect the whole network. As long as there is even one properly functioning PC, the network will be alive.

Also important to note is the lack of a system administrator or a central authority. This leads to a more efficient and stable network owing to lack of a full staff needed to ensure smooth running.

Weaknesses
Just like any kind of file sharing system, users are vulnerable to malicious attacks from harmful content that may allow remote access to the user’s PC. This can even affect the whole network.

Network Security
For one thing, sharing files with random strangers on the internet does call for some sort of caution. It is recommended that you at least have a firewall or an antivirus scanning each of your downloads to protect against potential backdoors and malware. Another way would be to just use trusted sources.
P2P networks represent one of the most important issues in the ongoing controversy of network neutrality. Internet Service Providers have been known to cut off P2P file sharing traffic on account of its high bandwidth usage.


But still we can expect this form of networking to only grow and grow more for its pros far outweigh its cons.

So P2P is a standard approach to network design that eliminates the need for dedicated servers. P2P is also a popular term for freely available Internet file sharing software systems.
