Video surveillance systems based on DMSS (Dahua Mobile Surveillance System) have long become the standard for remote monitoring via mobile devices. However, many users encounter difficulties when connecting cameras to their smartphone for the first time. Problems arise both due to incorrect network settings and due to the operating features of the application itself. This article will help you understand the nuances of setup, avoid common mistakes and ensure stable video broadcasting to your phone. Android. Problems arise both due to incorrect network settings and due to the operating features of the application itself. This article will help you understand the nuances of setup, avoid common mistakes and ensure stable video broadcasting to your phone.

We will look at all stages - from installing the application to fine-tuning motion notifications. We will pay special attention to Bypassing restrictions of providers that often block ports for remote accessand alternative methods of connecting through cloud services Dahua. If you use cameras from other brands (for example Hikvision or Uniview), some of the recommendations will also be useful, but the application interface may differ.

Before you begin, make sure that your video surveillance system supports protocol ONVIF or proprietary protocol Dahua. Most modern recorders (NVR) and IP cameras have this function by default, but in budget models it sometimes has to be activated manually through the web interface.

1. Equipment preparation: what to check before setting up

The first step is to diagnose your equipment. Without proper preparation, even a perfectly configured application DMSS will not be able to connect to the cameras. Start by checking the following parameters:

  • 🔌 Power and network: Make sure that the recorder (NVR/DVR) and cameras are plugged in and receiving power. The indicators on the case should light up green or blue (depending on the model). If you use PoEcameras, check that they are connected to PoEports of the switch or recorder.
  • 🌐 Local network: All devices (recorder, cameras, router) must be on the same subnet. For example, if the router distributes IP addresses in the range 192.168.1.1–192.168.1.255, then the registrar must have an address from this range (for example, 192.168.1.108).
  • 🔒 Firewall and antivirus: During setup, disable firewalls on the router and anti-virus software on your smartphone. They can block the connection with cameras, especially if used non-standard ports.
  • 📡 Internet connection: For remote access you will need static or dynamic IP address (in the case of dynamic, you will need a service DDNSCheck the download speed: for Full HD broadcast you will need at least 4–5 Mbit/s.

If you are using a recorder Dahua older than 2018, you may need to update its firmware. Outdated software versions often do not support modern encryption methods. which leads to connection errors. The update can be performed through the registrar's web interface (usually at http://[Registrar_IP-address]) in the Maintenance → Upgrade.

⚠️ Attention: If your Internet provider blocks incoming connections (for example, Rostelecom or Beeline in tariffs for individuals), the standard connection method via IP address may not work. In this case, immediately go to the section about cloud connection via Dahua Cloud.

2. Installation and initial setup of the DMSS application

The application DMSS is available for free, but some functions (for example, recording video to the cloud) may require a paid subscription. Download the latest version, as outdated releases often contain vulnerabilities and do not support new encryption protocols. Google Play free, but some features (like cloud video recording) may require a paid subscription. Download the latest version, as outdated releases often contain vulnerabilities and do not support new encryption protocols.

After installation, follow these steps:

  1. Open the application and accept the license agreement. Click Skip (Skip) if you do not want to register an account Dahua Cloud immediately.
  2. In the main menu, select Device Management (Device Management) → Add Device (Add device).
  3. Select the adding method:
    • Manual Add (Manual adding) - to connect by IP address or DDNS.
    • Scan QR Code - if there is a sticker with QR code.
    • P2P —for cloud connection through servers Dahua.
  • If you choose manual addition, specify:
    • Device name (for example, Home_Registrar).
    • IP address or DDNSregistrar address.
    • Port (default 37777 for Dahua, but may differ).
    • Login and password (often by default admin/admin, but it’s better to change!).

    If the application does not find the device, check:

    • 🔄 Correctness of the entered IP addresses (you can find out through the web interface router in the section DHCP Clients).
    • 🔌 Are the ports open on the router (see the next section).
    • 📱 Application permissions DMSS in settings Android (access to the network, camera, storage).

    3. Configuring ports on the router for remote access

    To directly connect to the recorder from the Internet, you need to forward ports on the router. This process is called portforwarding (port forwarding. Without this step, the application DMSS will only be able to work on the local network.

    Instructions for most routers:

    1. Open the router's web interface (usually at 192.168.1.1 or 192.168.0.1). The login and password are indicated on the device sticker.
    2. Go to the section Forwarding (Port Forwarding) or NAT → Port Forwarding.
    3. Add a new rule:
      • External port (External Port): 37777 (or another, if you changed in the recorder).
      • Internal port (Internal Port): the same as the external one.
      • IP address (Internal IP): the address of your recorder on the local network (for example, 192.168.1.108).
      • Protocol (Protocol): TCP/UDP or ALL.
  • Save the settings and reboot the router.
    • Router model Path to forwarding settings Notes
    TP-Link (Archer, TL-WR) Advanced → NAT Forwarding → Port Forwarding In new firmware it may be called Virtual Servers.
    ASUS (RT-AC, RT-AX) Internet → Port Forwarding Supports the creation of rules for port ranges.
    Keenetic Security → Port Forwarding Requires preliminary reservation IP addresses for the registrar.
    Zyxel (Keenetic) Home Network → Port Forwarding In some models, you must first enable DMZ.

    If your provider uses CGNAT (for example, MTS or Megafon in some regions), port forwarding may not work. In this case, the only reliable way is to use DDNS or a cloud service Dahua Cloud. Also check what you have white (public) IP address. You can find it on the website 2ip.ru —if it matches the address in the router's web interface, it means IP gray and port forwarding will not work.

    ☑️ Checking port forwarding

    Done: 0 / 4

    4. Connection via DDNS: if you have a dynamic IP

    If your provider issues a dynamic IP IP address (changes with each connection), it is inconvenient to use it for remote access. The solution is a service DDNS (Dynamic DNSthat binds a permanent domain name to your address (for example, mydvr.dDNS.net).

    Dahua provides a free DDNSservice, but it can only be used with their equipment. Alternatives:

    • 🔗 No-IP: Free tariff with confirmation every month. Domain type yourname.ddns.net.
    • 🔗 DynDNS: Paid but reliable service with support HTTPS.
    • 🔗 Synology DDNS: If you have a NAS from Synology, you can use their service.

    Setting up DDNS on the registrar Dahua:

    1. Go to the web interface of the registrar (http://[IP address]).
    2. Go to Configuration → Network → DDNS.
    3. Enable DDNS and select the service (for example, Dahua DDNS or No-IP).
    4. Enter your account details (if required) and save.
    5. Copy the generated domain (for example, abc123.dahuaddns.com) and use it instead IP addresses in the application DMSS.

    If the domain is not updated automatically, check:

    • 🔄 Settings UPnP on the router (must be enabled if you use Dahua DDNS).
    • 🔌 Internet connection status (if the connection is lost, the domain will stop updating).
    • 📡 Correctness of the entered account data DDNSservice.
    ⚠️ Attention: Free DDNSservices (for example, No-IP) require monthly confirmation of account activity. If you do not log into your personal account for more than 30 days, the domain may be deleted. To avoid losing access, set up a reminder or use a paid one. tariff.

    5. Cloud connection via Dahua Cloud (without port forwarding)

    If port forwarding is not possible (due to CGNAT or provider restrictions), the most reliable way is to connect via cloud Dahua Cloud. This method works even with gray IP address and does not require complex router settings.

    Step-by-step guide:

    1. Download and install application DMSS (if you have not done so already).
    2. Register an account Dahua Cloud:
      • Open DMSS, click Me (I) → Register (Registration).
      • Enter a valid email and create a password.
      • Confirm registration using the link in the letter.
  • Add the device to the cloud:
    • In the web interface of the recorder, go to Configuration → Network → Platform Access.
    • Enable Enable and select Dahua Cloud.
    • Enter your account information Dahua Cloud and save.
    • Wait for synchronization (may take up to 5 minutes).
    • In the application DMSS refresh the list of devices - the recorder should appear automatically.

    Advantages of cloud connection:

    • ✅ Works with any IP address (including gray).
    • ✅ Does not require port forwarding.
    • ✅ Supports P2Pconnection, which is more difficult to block provider.
    • ✅ Ability to share access to cameras with other users.

    Disadvantages:

    • ❌ Dependency on servers Dahua (if failures occur, access will be lost).
    • ❌ Possible video delays (latency up to 2-3 seconds).
    • ❌ Limitation on the number of connected devices in the free plan.
    💡

    If the cloud Dahua does not connect, try changing the DNS server on the router to 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare). Sometimes connection problems are associated with blocking at the DNS level.

    6. Setting up motion notifications and recording video

    One ​​of the key functions DMSS is motion and sound notifications. To set up notifications:

    1. In the application, select the desired camera and click Settings (Settings) → Motion Detection (Motion detection).
    2. Enable Enable Motion Detection.
    3. Configure sensitivity zones:
      • Select Region (Area) and draw a rectangle on the area where you want to track motion.
      • Set Sensitivity (Sensitivity) to Medium (Medium) to avoid false positives.
  • Enable Push Notifications (Push notifications) and specify the activity time (for example, only at night).
  • Save the settings and test by walking in front of the camera.

    • To record video when the motion sensor is triggered:

    • 📹 In the camera settings, enable Record (Record) → Motion Triggered (By motion).
    • 💾 Specify the storage location:
      • Device — to the recorder's hard drive.
      • Cloud — to the cloud Dahua (requires subscription).
      • Phone — to the smartphone memory (recordings take up a lot of space!).
    • ⏱ Set the recording duration after triggering (optimally - 10–15 seconds).

    If notifications do not arrive:

    • 🔔 Check resolution DMSS in settings Android (section Apps → DMSS → Notifications).
    • 📵 Make sure that the phone is not set to Do not disturb or energy saving for DMSS.
    • 🌐 Check your Internet connection (notifications only work when the connection is active).
    How to reduce the number of false positives?

    Exclude areas with constant traffic (trees, road outside the window) from detection zones. Reduce sensitivity to Low and increase the minimum object size. in settings Motion Detection. You can also set up a schedule so that notifications only arrive at a certain time.

    7. Solving common problems

    Even with correct configuration, errors may occur. Let's look at typical situations and ways to eliminate them:

    Problem Possible cause Solution
    Device Offline (Device is offline) The recorder is turned off or not Internet. Check the power and network connection. Reboot the recorder.
    Network Unreachable (Network unavailable) Port forwarding does not work or is blocked by the provider. Try a cloud connection or change the port to 8000.
    Invalid User Name or Password Invalid login information. Reset the password through the web interface of the recorder (Forgot Password).
    Video lags or slows down Low Internet speed or high channel load. Reduce the stream resolution in the camera settings (Stream Type → Sub Stream).
    No sound from cameras The audio stream is disabled in the camera settings. Enable Audio in the web interface of the recorder (Camera → Audio).

    If the application DMSS constantly crashes or does not open:

    • 📱 Clear the application cache in settings Android (Apps → DMSS → Storage → Clear Cache).
    • 🔄 Reinstall the application.
    • 📋 Check compatibility with your version Android (minimal - Android 6.0).
    ⚠️ Attention: If you are using a registrar Dahua older than 2019, it may contain a vulnerability that allows hackers to access your cameras via the Internet. Update the firmware to the latest version or disable remote access if you do not use it regularly. The list of vulnerable models can be checked on the manufacturer’s website.

    8. batteries

    Constantly broadcasting video from cameras can quickly drain the battery and consume mobile traffic. To avoid this:

    • 📶 Limit the quality of the stream:
      • In the camera settings in DMSS select Stream Type → Sub Stream (secondary stream with lower resolution).
      • Set the bitrate no higher 512 Kbps to save traffic.
    • 🔋 Set up power saving modes:
      • In settings Android add DMSS to battery optimization exceptions (Settings → Battery → Battery Optimization).
      • Disable background activity of the application if you do not need push notifications.
    • ⏳ Use a schedule:
      • Turn on the broadcast only at certain times (for example, at night or when you are not at home).
      • Set up geofences: the application will automatically connect to cameras when you leave the house.

    Example of traffic consumption:

    • 📊 720p, 10 frames/s, 512 Kbps → ~225 MB/hour.
    • 📊 1080p, 15 frame/s, 2048 Kbit/s → ~900 MB/hour.

    If you often watch archived recordings, download them via Wi-Fi, and not the mobile network. You can also set up automatic deletion of old recordings from your phone in the settings. DMSS (Settings → Storage → Auto Cleanup).

    💡

    For maximum traffic savings, use detection mode: video will be broadcast only when motion is detected, and not constantly.

    FAQ: Frequently asked questions about connecting DMSS

    Is it possible to connect Hikvision cameras to DMSS?

    Yes, but with restrictions. DMSS officially supports only equipment Dahua, but some cameras Hikvision (especially with protocol ONVIF) can be added manually. To do this:

    1. Enable ONVIF in the settings. cameras Hikvision.
    2. In DMSS select Add Device → ONVIF Device.
    3. Enter IP address, port (80 or 554) and login information.

    However, functionality will be limited (for example, there will be no support for cloud notifications).

    Why does the video in DMSS only show a black screen?

    This problem is usually associated with:

    • Incorrect stream selection (Main Stream instead of Sub Stream).
    • Blocking ports on the router or firewall.
    • Incompatible codec (try changing H.265 to H.264 in the camera settings).

    Also check that the camera actually transmits video (you can check through the web interface of the recorder).

    How to reset the password from the Dahua registrar?

    If you have forgotten the password from the registrar, there are two ways to reset:

    1. Through the Reset button:
      • Press and hold the button Reset on the rear panel recorder 10–15 seconds.
      • The recorder will be reset to factory settings (the password will be admin/admin).
