How to Access Your IP Surveillance Camera via the Internet: A Step-by-Step Guide

 

How to Access Your IP Surveillance Camera via the Internet: A Step-by-Step Guide

Introduction: Why does it work at home but fail when I leave?

You bought a new IP camera, connected it to your WiFi, and it works perfectly while you're sitting on your couch. But the moment you leave the house and switch to 4G/5G or office WiFi – the screen goes black. "Connection Failed."

This is the most common issue our IT clients face.

The reason is simple: Your camera lives inside your Local Area Network (LAN), protected by your router's firewall. To access it from the outside world (the Internet), you either need to "punch a hole" through that security (Port Forwarding) or use a middleman (P2P/Cloud).

In this guide, as IT professionals, we will walk you through the three best ways to set this up, from the easiest to the most professional.


Method 1: P2P (Peer-to-Peer) and Cloud – The Easy Way

Best for: Hikvision, Dahua, Reolink, and most consumer-grade cameras.

Today, 90% of modern cameras come with a P2P feature. This eliminates the need for complex router configurations.

  1. Find the QR Code: Look for a QR code on the camera box, the device sticker, or in the device menu (under Network > P2P or Platform Access).

  2. Download the App: Use the manufacturer’s official app (e.g., Hik-Connect, DMSS, Ezviz).

  3. Scan and Add: Open the app, create an account, and scan the QR code.

How does it work? The camera initiates a connection to the manufacturer's server, and your phone connects to the same server. The server "bridges" the two. No port forwarding required.

Method 2: Port Forwarding & DDNS (The Professional Way)

Best for: Advanced users, Smart Home integration, or avoiding third-party cloud servers.

If you want direct access to your camera without a middleman, this is the way. It requires accessing your router's admin panel.

Step 1: Assign a Static IP to Your Camera

Your router changes device addresses frequently (DHCP). Your camera needs a permanent address (e.g., 192.168.1.50).

  • Log into the camera's web interface (Network settings).

  • Disable "DHCP".

  • Enter a fixed IP address that is outside your router's DHCP range.

Step 2: Port Forwarding

Now you must tell your router: "When someone from the internet knocks on this specific door, send them straight to the camera."

  1. Log into your router (usually 192.168.1.1 or 0.1).

  2. Find the Forwarding, Virtual Server, or NAT section.

  3. Add a new rule:

    • Service Port (External): e.g., 8080 (This is what you will type in your browser).

    • Internal IP: Your camera's static IP (from Step 1, e.g., 192.168.1.50).

    • Internal Port: The port the camera listens on (usually 80 for web or 37777/8000 for apps – check your manual).

    • Protocol: TCP/UDP (or Both).




Step 3: DDNS (Because your home address changes)

Most home internet plans have a Dynamic Public IP. This means your "home address" on the internet changes every time you restart your router. To avoid checking your IP every day, use DDNS (Dynamic DNS).

  • Services like No-IP or DynDNS map your changing IP address to a fixed hostname, like mycamera.ddns.net.

  • Enter this hostname into your camera app instead of the IP address.


Method 3: VPN (The Most Secure Way)

Opening ports (Method 2) carries a slight security risk – hackers can scan for open ports. The enterprise-grade solution is setting up a VPN Server at home (many routers like Asus or MikroTik support this).

  • When you leave home, turn on the VPN on your phone.

  • Your phone creates a secure "tunnel" back to your house.

  • You access the camera using its local IP (192.168.1.50) as if you were still in your living room.


The "Hidden" Problem: CGNAT (ISP Restrictions)

Did you follow all the steps above, but it still doesn't work? You are likely behind CGNAT (Carrier-Grade NAT). ISPs often run out of public IP addresses, so they make hundreds of customers share a single public IP.

  • How to check? Look at the WAN IP in your router. If it starts with 100.x.x.x or 10.x.x.x, but websites like "WhatIsMyIP" show a completely different number – you do not have a real public IP.

  • The Fix: Port Forwarding will not work. You must either use Method 1 (P2P) or call your ISP and pay extra for a "Static Public IP Address".

Security Warning!

Before exposing any camera to the internet:

  1. ALWAYS change the default password (never leave it as admin/admin). Botnets scan the internet looking for these specific defaults.

  2. Update your camera's Firmware regularly to patch security holes.

Typical Router Problems and How to Fix Them (Updated 2025)

 

Introduction

Your router is the heart of your home network. If your WiFi keeps dropping, speed is inconsistent, or devices randomly disconnect — the issue is usually a simple configuration problem, interference, or an aging router.
Here is a complete guide with real-life, practical fixes based on years of hands-on experience.




1. Weak WiFi signal in certain rooms

Symptoms:

  • full bars but slow speed

  • WiFi disappears in the bedroom/kitchen

  • speed much lower on phones than on a laptop near the router

Causes:

  • walls, tiles, concrete

  • interference from microwaves, Bluetooth, smart devices

  • poor router placement

Fix:
✔ Place the router higher and centrally
✔ Don’t hide it behind a TV or furniture
✔ Enable 5GHz (faster, cleaner signal)
✔ For larger homes: use a WiFi extender or mesh system


2. Internet works sometimes, then stops (intermittent connection)

Causes:

  • router overheating

  • outdated firmware

  • network congestion

Fix:
✔ Restart router for 30 seconds
✔ Update firmware from admin menu
✔ Keep router in open, ventilated space
✔ If over 4 years old — consider replacement


3. Slow speed despite having a good internet plan

Causes:

  • overcrowded WiFi channel

  • old 2.4GHz router

  • wrong channel settings

Fix:
✔ Switch to a less crowded WiFi channel
✔ Use 5GHz when possible
✔ Scan signals using “WiFi Analyzer”
✔ Consider buying your own, better router


4. Devices connect to WiFi but have no internet

Causes:

  • ISP issue

  • DNS failure

  • wrong IP assignment

Fix:
✔ Test connection via cable
✔ Set manual DNS (Google DNS):
8.8.8.8 / 8.8.4.4
✔ Restart router and modem


5. Devices refuse to connect (password error, WPS, DHCP)

Fix:
✔ Disable WPS
✔ Change SSID + password
✔ Ensure DHCP is ON
✔ If nothing helps — factory reset (10 sec button)


6. Router freezes or restarts by itself

Causes:

  • overheating

  • faulty power adapter

  • weak hardware

  • corrupted firmware

Fix:
✔ Improve airflow
✔ Replace adapter
✔ Update firmware
✔ Replace router if crashing under heavy load


7. Interference in apartment buildings (2.4GHz)

Fix:
✔ Use 5GHz whenever possible
✔ On 2.4GHz stick to channels 1, 6 or 11
✔ Re-test using “WiFi Analyzer”


8. When should you replace your router?

Replace if:

  • older than 5 years

  • lacks 5GHz

  • overheats

  • unstable under multiple devices

  • WiFi much slower than cable

πŸ“Ή How to Access Your IP Security Camera Over the Internet

 




πŸ“Ή How to Access Your IP Security Camera Over the Internet

Modern IP cameras allow you to monitor your home, office, or business from anywhere in the world — using just a web browser or a mobile app.
However, for many users, setting up remote access can be confusing due to router configuration, IP addressing, and security concerns.

In this complete guide, you’ll learn how to connect and access your IP camera remotely, both from your local network (LAN) and over the Internet (WAN).
We’ll also cover common issues, security best practices, and cloud-based alternatives.


1. What You Need

Before setting up remote access, make sure you have:

  • An IP camera with Ethernet or Wi-Fi connection

  • Access to your router’s admin panel

  • A stable Internet connection

  • (Optional) a Dynamic DNS (DDNS) account if your ISP changes IP addresses frequently

Most IP cameras come with a default IP address like 192.168.1.10 or 192.168.0.100.
You can find it in the user manual or by using a free network scanning tool such as Advanced IP Scanner or Angry IP Scanner.


2. Accessing Your Camera on a Local Network (LAN)

This is the easiest way to check if your camera works properly before opening it to the Internet.

✅ Steps:

  1. Connect your camera to the same Wi-Fi or LAN network as your computer.

  2. Open a web browser and type the camera’s IP address (e.g. http://192.168.1.10).

  3. Log in using the default credentials (usually admin / admin).

  4. Configure the camera’s network settings — set a static IP address to prevent future conflicts.

You should now see a live video feed within your local network.


3. Enabling Internet Access (WAN)

To view your camera remotely (from outside your home network), you’ll need to set up port forwarding on your router.

✅ Steps:

  1. Log into your router (usually via 192.168.1.1).

  2. Go to Port Forwarding / Virtual Server settings.

  3. Create a rule:

    • Internal IP: your camera’s LAN IP (e.g. 192.168.1.10)

    • Internal Port: 80 (or 8080 / 554 depending on the camera)

    • External Port: same as internal (or choose custom)

  4. Save and reboot the router.

Now you can access your camera remotely by typing your public IP and port, for example:

http://[your_public_IP]:8080

πŸ‘‰ To find your public IP, visit: https://whatismyipaddress.com


4. Using Dynamic DNS (DDNS)

If your Internet provider assigns a dynamic IP address, it will change periodically — making it impossible to reconnect without knowing the new one.

That’s why you should use Dynamic DNS.
Popular free services include No-IP, DuckDNS, and Dynu.

These services give you a fixed domain name (like myhomecam.ddns.net) that automatically updates whenever your IP changes.
Most modern cameras and routers support DDNS directly in their settings.


5. Mobile Access (via App or Cloud)

Almost all IP cameras now offer mobile access apps that simplify remote viewing without manual port forwarding.

✅ Examples:

  • TP-Link Tapo / Kasa

  • Reolink App

  • Hik-Connect (Hikvision)

  • Ezviz

  • Tuya Smart / Smart Life

Just scan the QR code on your camera, create a cloud account, and you can monitor your home from anywhere — even receive motion alerts and push notifications.

Cloud apps are generally safer and easier for beginners since they use encrypted P2P connections.


6. Security Tips

Exposing your camera online can be risky if not done properly. Follow these rules:

  • πŸ”’ Change default username and password immediately.

  • 🚫 Disable UPnP if not needed — it can open ports automatically.

  • 🧱 Use a strong admin password (mix of letters, numbers, and symbols).

  • πŸ”„ Update firmware regularly to patch security vulnerabilities.

  • πŸ” Consider using VPN access for maximum security instead of open ports.


7. Common Problems and Fixes

Problem Cause Solution
Can’t access camera remotely Wrong port forwarding Recheck IP and port mapping
Camera not showing video Browser plugin issue Use Internet Explorer mode or official app
DDNS not working Incorrect configuration Verify DDNS username and password
Mobile app not connecting Poor Wi-Fi or NAT conflict Reboot router and camera

8. Alternatives to Manual Setup

If you prefer not to configure routers and ports manually, consider using:

  • Cloud camera systems (Arlo, Nest, Blink, Eufy)

  • VPN-based access — secure but requires setup

  • NVR with remote access — one central recorder for multiple cameras

These solutions offer automatic configuration, encryption, and often support multiple cameras under one account.


Final Thoughts

Setting up remote access for your IP camera may seem technical, but once configured properly, it gives you complete control and peace of mind wherever you are.
Always prioritize security and reliability — don’t expose your camera directly to the Internet without protection.

With the right setup, you can monitor your property anytime, from any device — safely and efficiently.

Typical problems with the INTERNET router and how to solve them?


A router is a device that nowadays is present not only in companies but also in every family that understands and knows how to use the possibilities and advantages of information technologies.

So, the internet. computers and smart devices have become part of our everyday business and private lives.

In order to be able to provide Internet access to all devices and all members in the house, we need a device called a router. The router is in this case

I have a device that is also our access point to our network and the Internet, that is ACCESS POINT.




 PROBLEM No. 1

You bought a new router, and now you have the job of plugging it in, setting it up to work properly.

 As we mentioned, the initial step is to connect the LAN cable from the modem, coaxial, DSL or FiOS, which was assigned to you by your ISP (Internet Service Provider) to the router (the WAN signal lamp flashes if you have a signal), as well as the router's power supply.

Manufacturers deliver a SETUP CD with each of their devices, that is, an installation CD that guides you through the installation of your device. In this way, the key parameters are automatically adjusted, and if you are not very pro level with network devices, this is the recommended way for you.

Either way, there are a few things you'll need to learn about your router, and that's what we're going to focus on in this post.

You can receive the Internet signal from the router wirelessly or via a network LAN cable.

Confirmation that WiFi (wireless broadcasting) is turned on on your router is the flashing of the WLAN indicator.

If WiFi is turned on, it is necessary to set a WPA or WPA2 PSK password to prevent unauthorized use of your network.

Possible situation No. 1: you have done everything but you still do not see a signal from your router. It is advised to disconnect the cables between the router and the modem and disconnect the modem from the power supply for at least 30 seconds, then connect everything again.


Situation #2: You ran the software from the installation CD but it reported that it could not find your router even though you connected your computer with a LAN cable to one of the router's ports.


Solution: You need to open network settings on your computer (Windows 7):

Control Panel - Network and Internet - Network Sharing Center - Change Adapter Settings

Then right-click on the LAN connection and open Properties, then select Internet Protocol version Version 4 (TCP/IPv4), then select Properties again:





Check "Use the following IP address." Now you will be in a situation where you have to enter IP addresses manually, so that the first one (the IP address of your computer) is different from the IP address of your router, which is usually "192.168.1.1", so you enter: "192.168.1.2" in the first field. This is because you know that two devices (in this case a computer and a router) on a local network cannot have the same IP address. . In the "Subnet mask" field, type "255.255.255.0"—typical for a home network, and in the "Gateway" field, type the router's default IP address—"192.168.1.1."

You have to do the above most often when the DHCP option is not enabled on the router (

Dynamic Host Configuration Protocol) because it is an option that ensures that all devices connected to the router get different IP addresses.

Otherwise, as far as router settings are concerned, you access the router interface by entering the IP address of the router in the URL field of your web browser: 192.168.1.1.

Then you will be asked for a username and password, which is determined by the router manufacturer, and when you enter it, you enter the router interface.


PROBLEM No. 2

Your network name has disappeared from the list of networks seen by your devices

During the setup that you did by starting the CD, you must have been asked for the name of your network, which other devices will see and which you selected and entered. The name of that network on the router is the SSID and it broadcasts it to the environment as a signal name.

 If you have accessed the router one of the options available with the router is to set it to broadcast the name of your network (Network Name Broadcasting) or not to do so, so your network will not be visible.

For security reasons, you can also make your network invisible, but it is assumed that you have previously set up all your devices to receive the signal.


If it happened (and not by your will), to make your network name disappear you have to do the following:

Set your computer or other device to connect to your router even when it's not broadcasting a network name!


 Control Panel->Network and Internet->Network and Sharing->Manage Wireless Networks.

If you see your wireless network listed, right click on it and go to properties. Select the option "Connect even if the network is not broadcasting its name (SSID)."


If you don't see your network listed, click "Add" and select "Manually connect to a wireless network" then enter your network information.



PROBLEM No. 3

There are frequent signal interruptions from your router

You are carelessly surfing the Internet and suddenly the Internet signal is interrupted.



Potential Solution: This is a common problem, especially for those using cable internet or FIOS. The cause is the instability of the signal, and the reason is usually the splitter. So replace the splitter according to the following.




PROBLEM No. 4

Port forwarding does not work on the router

When you have an IP camera in the network, for example, you need to provide an open port for it so that you can access it via the Internet from a remote location. That router feature is called "port forwarding," and when you've configured your router for an application, there's a tool to check if the appropriate port is open.

One of the links that offers such a check is here!



PROBLEM No. 5

 You forgot the password to access the router or your network

 If you face the situation of forgetting the password to access your router or your network, it is solved by resetting your router to factory settings.

How is it done?

There is a RESET button on the back of the router:





 Using a paper clip, press the button and hold it until the LEDs flash, or as long as the manufacturer provides for a factory reset.

Then access the router with factory settings and you can set a new password.

Newer routers have options to save the appropriate settings, so the previous procedure is not necessary, you just find them.


PROBLEM No. 6


My new device (tablet, smart phone) won't connect to my network

Example: You know your router is working because you can connect to it through your laptop without any problems, but you can't seem to connect your new tablet or game console to it.


So what's the problem?

The first thing you need to confirm is whether your new device is working, which is determined by connecting it to another network, or wifi hotspot. If it connects, go to the next step...

The reason may be the following:

Your router is "dual band", that is, it emits a signal on two frequencies: 2.4GHz and 5GHz, and your new device connects to the wrong one.

Some routers use the same SSID for both frequencies, so some devices may not automatically connect to the correct one. Almost all tablets, e-readers, gaming systems connect to 2.4 GHz.

Only newer wifi devices connect to 5GHz.

It is advised that when you setup the router, you set different SSID network names for each band (frequency).

Earnings on the Internet, Google Adsense, Affiliate marketing, Youtube channel - real analysis!?

 Google AdSense displays ads and counts clicks from all territories, but earnings depend on the visitor's country. Here's how it works:


1. Clicks are counted from all countries, but CPC varies

Google AdSense records all clicks, regardless of where they come from.

The cost per click (CPC - Cost Per Click) depends on the country of the visitor and the advertisers competing for that space.

America, Canada, Australia, UK and Germany have the highest CPC, while the Balkan countries are at a lower level.

2. The problem of low income for the Serbian language

Since your blog is in Serbian, most visitors come from Serbia, BiH, Montenegro, etc.

Ads in Serbian usually have a lower value, because there are not many advertisers who pay high prices for ads in the Balkans.

CPC in Serbia can be $0.01 - $0.05 per click, while in America it can be $1 - $5 per click.

3. Is it worth placing AdSense on a blog in Serbian?

✅ YES, if you have a lot of visits!


If your blog has thousands or tens of thousands of visits per day, a solid income can be collected.

It is not only CPC that matters, but also RPM (earnings per 1000 impressions) which can bring in additional income.

❌ NO, if you expect quick and big earnings


If you have few visits, the earnings will be symbolic (a few dollars a month).

Perhaps a better choice would be affiliate marketing or sponsored posts.

4. How to improve earnings?

If you want to earn more from AdSense:

✅ Write content in English (or another language with a higher CPC).

✅ Attract visitors from developed countries (SEO optimization for a global audience).

✅ Uses other sources of monetization (Affiliate marketing, product sales, sponsored articles).

✅ Connect AdSense with Ezoic or Mediavine (they pay better for ads, but require more visits).


Conclusion

If your blog has an exclusively Balkan audience, AdSense will bring you very little profit, but it's not useless if you have a lot of traffic. If you want more serious income, consider alternative monetization methods.


Do you have any specific idea how to monetize your blog besides AdSense? 😊


What are all the YouTube channel earning opportunities available?




YouTube offers multiple ways to monetize, but earnings depend on multiple factors, including language, audience, niche, and geographic location. Here's an overview of all the earning opportunities:


1. Earnings from ads (AdSense monetization)

How does it work?

When you join the YouTube Partner Program (YPP), Google AdSense displays ads on your videos.

You earn money based on:

CPM (Cost Per Mille) → earnings per 1000 views with ads.

CPC (Cost Per Click) → if someone clicks on an ad in your video.

VRPM (Viewable Revenue Per Mille) → earnings per 1000 monetized views.

What are the conditions for monetization?

To start earning from ads, you must meet the following criteria: ✅ 1000+ subscribers

✅ 4000 hours of viewing in the last 12 months or 10 million views of Shorts videos in the last 90 days

✅ No violation of YouTube rules

✅ Linked AdSense account


How much can be earned?

πŸ’° CPM varies by country and niche:


US, UK, Canada, Australia → $4 - $20 CPM

Balkans (Serbia, Croatia, BiH...) → $0.5 - $3 CPM

πŸ”Ή Example:

If the video has 100,000 views and the CPM is $2, the total earnings would be about $200, but YouTube takes 45% of that, leaving you with about $110.


2. YouTube Shorts monetization

Short video clips (Shorts) can bring income if you are part of the Partner program.

Earnings from Shorts ads are not high, as they are shared among all creators.

A better option is to use Shorts as a tool to grow your channel and drive your audience to longer videos.

3. Memberships on the channel (YouTube Memberships)

Subscribers can pay a monthly membership fee in exchange for exclusive benefits (eg special emojis, early access to videos).

YouTube takes 30% of the commission, and you keep 70%.

πŸ’‘ Example: If 100 people pay $5 a month, your earnings are about $350 a month (after YouTube commission).


4. Super Chat and Super Stickers (During live streams)

Viewers can pay to have their message highlighted during the live broadcast.

Super Stickers are similar, but animated.

YouTube takes a 30% commission.

πŸ’‘ Example: If you win $100 from Super Chat, you have $70 left.


5. Affiliate marketing (Earnings without AdSense!)

You recommend products in video descriptions and receive a commission from each sale.

Amazon Affiliate, Aliexpress, Udemy, Hosting Companies, Tech Products - Great Earning Programs.

πŸ’‘ Example: If you record phone reviews and put an affiliate link to Amazon, you can earn up to 10% commission per purchase.


6. Sponsored Content

Brands can pay you to promote them in your videos.

Earnings depend on niche, number of followers and audience engagement.

πŸ’‘ Example: Influencers in the tech niche often get $500 - $5000 per sponsored video.


7. Sale of goods (Merchandise)

You can sell t-shirts, hats, mugs and other products directly through the YouTube Merchandise shelf (if you have 10,000+ subscribers).

Teespring, Spreadshirt, Redbubble are popular platforms for this kind of sale.

πŸ’‘ Example: If you sell 100 shirts at $20, with a profit of $10 per shirt, that's $1000 in profit.


A good connection is also required to work over the Internet!
