In this article, we will discuss how you can connect a CCTV camera directly to your mobile device – regardless of whether you have access to Wi-Fi or broadband – and some alternative solutions that provide ease of use and added convenience. We will also explore considerations for choosing a camera, such as features and size, so that you can select one that meets your specific needs. Also discussed will be basic setup information for each solution so that you get up and running quickly and easily with your new security system.

Hardware Requirements

If you want to connect a CCTV camera to your phone, you will need the right hardware. The first thing you will need is a CCTV camera with a BNC connector. You will also need a BNC-to-RCA converter and two RCA-to-3.5mm cables. Once you have all the necessary hardware components, you will then be ready to make the connection between your CCTV camera and your phone without the need for an internet connection.

CCTV Camera

A Closed-Circuit Television (CCTV) camera is a type of video surveillance technology that monitors property and areas. It is connected to a device or multiple systems, allowing the user to observe activity within its field of vision. This type of surveillance technology can be used in both commercial and residential applications.

In order to connect a CCTV camera to your phone, you need the following hardware components:
-CCTV Camera – This is the device that will record video footage from the specified area.
-Connection cables for CCTV Camera – These are used for connecting the CCTV camera to a monitor, recording device, or other hardware. Common connection cables include BNC cables and Ethernet cables.
-Monitor – This is an electronic device used for viewing the recorded footage from your CCTV camera such as a television, computer monitor, tablet display, or smartphone screen.
-Transmitter – This is an electronic device used to send information wirelessly from your CCTV camera to your communication system such as your phone or other devices.
For connecting a CCTV Camera without internet requires wireless transmitters such as A/V wireless transmitters, Wi-Fi enabled wireless adapters and Bluetooth enabled adapters etc., depending on what type of system needs connecting with it at each location in order for this transmission without internet connection.


The monitor is an important element of any CCTV setup as it will be used to view the live footage being recorded by the camera. If you plan to connect your CCTV camera to a smartphone, tablet or laptop, then you will need to make sure that your selected device is able to handle the video stream from your camera. Depending on the quality of the video stream, this may involve upgrading hardware such as the processor and graphics card of your device.

You may also need additional hardware such as an analog-to-digital converters and Ethernet adapters if you plan to connect directly over a local network rather than through an internet connection. If using a Wi-Fi connection, you will need compatible routers, range extenders and other wireless devices in order for the signal strength of your connectivity to stay consistent throughout different parts of your home or workplace.

To ensure smooth playback on high resolution devices like smartphones or tablets, we recommend investing in a good quality monitor with at least 1080 pixels resolution and high refresh rate (such as 120 Hz). This can be costly but it’s worth it if you plan to use CCTV for professional surveillance footage or for home security purposes. Other things to consider include how easy it is to set up and mount the monitor onto walls or shelves in order optimize its usage space.

Video Cable

For proper installation of your CCTV camera, you need to make sure that you have the right type of video cable. The most common types of cables used with CCTV cameras are coaxial cables and twisted pair wires.Depending on your camera type, select the appropriate video cable with the necessary transmission range. Coaxial cables are widely used with Analog CCTV cameras, while twisted pair wires are used for IP Cameras.When selecting wire gauge size for both coaxial and twisted pair wires, the recommendation is to use a minimum of 18 Gauge Wire in order to ensure good signal quality. When using coaxial cables, pay attention to selecting high-resolution RG59 or RG6 grade cable instead of low-resolution models like RG58 or RG59C/U as these could negatively affect image quality and color accuracy. Additionally, for extra protection against interference it is recommended to have BNC connectors fitted on both ends of the coaxial cable as it limits the potential for moisture penetration that could lead to corrosion and poor connections over time.

Power Supply

For most CCTV camera set-ups, you’ll need an external power supply that runs the camera and powers any additional components. This could be a direct connection to a wall outlet, or it could include an external battery system that can be recharged by a standard power outlet or solar panel. Depending on the size of your system and its associated components, it’s possible to get power from multiple outlets.

Also consider using surge protectors or voltage regulators for your system, particularly if the surveillance site is in an area prone to electrical surges like thunderstorms. And for extra protection against lightning strikes, it’s important to have appropriate grounding cable with the right-rated connectors connected between the cameras and their power supplies. Doing so will quickly dissipate any static electricity buildup.

Connecting the CCTV Camera to Phone

Connecting a CCTV camera to a phone without the need for an internet connection is a convenient way to secure your home or business. With a dedicated CCTV camera, it’s possible to monitor a property remotely without the need for a constant internet connection. In this article, we will discuss the steps to connect a CCTV camera to a phone without an internet connection.

Connect the CCTV Camera to the Monitor

Connect the CCTV camera to the monitor using a BNC (Bayonet Neill-Concelman) coaxial cable provided in the package. This cable will provide a direct connection from the camera to the monitor, bypassing any external connections such as a wi-fi or a router. The BNC is also used to connect other audio and video equipment such as TV sets, speakers, and projectors.

Make sure that both the camera and monitor have the same ports for connection. Most gates typically use either one single plug or two plugs for power supply. Connect this plug directly into back of your monitor or an appropriate outlet if necessary.

The white port on your camera should be inserted into the power port on your monitor, usually labeled “V+” while the yellow port should be inserted into one of two ports labeled “Video in” on either side of this piece of equipment. Lastly, unitize one end of your coaxial cable in order to attach it with both ends securely connected together with each other.

Connect the Monitor to the Phone

If you want to connect a CCTV camera directly to your phone without using the Internet, then this method is perfect for you. Before starting the connection process, it is important to have the necessary cables and an adapter ready. The cables usually come with the purchased CCTV camera.

Once you have acquired all the cables, begin by connecting one end of the video cable to your camera and plug in a VGA converter into the other end of it. Then take another cable and connect it from the converter’s VGA port to your smartphone’s headphone jack or USB port. Each cell phone may require different kinds of connectors so make sure that you check these before purchasing them online or at an electronics store.

Once everything is connected, turn on your camera and select “monitor out” on its menu settings. Now you should be able to view live footage from your CCTV cameras on your mobile device. Remember that this method will only work if there is no power surge, otherwise signal interference might occur which can disrupt footage transmission. Also ensure that all connections are secure since loose wires can cause problems as well.

Connect the Phone to the Power Supply

Ensuring that your CCTV camera has the necessary power supply is the first step in connecting it to your phone. Most CCTV cameras will come with a 12V AC/DC adaptor, which you should plug into both the camera and a nearby wall socket. Additionally, if you want to operate your camera outdoors, make sure that it is powered by an external output of enough volts-such as 24VAC-to power up adequate voltage for those specific models. Once you have connected the power supply, you can move on to connecting your phone with the CCTV camera.

Test the Connection

Before connecting your CCTV camera to your phone, you should test the connection to make sure that everything is working properly. You can do this by using a direct connection with a phone or laptop, or by using a third-party app to connect the camera directly to your phone. Once you have established a successful connection, you can then move on to connecting the camera to your phone without internet.

Test the Camera

Now that you have the required hardware and all necessary tools to hand, the next step is to test the CCTV camera. To do so, connect one end of the BNC cable (which should have been supplied with your CCTV camera) to the video output port of your camera, and connect the other end of the cable to a BNC monitor or a TV. Now turn on your CCTV camera and check if an image appears onscreen. If it does, it means that all components are working properly and there is nothing further you need to do.

If you don’t have a BNC monitor or a TV for testing purposes, then look for another way to test the connection such as connecting it directly to your phone using Wi-Fi Hotspot or Bluetooth connectivity. To test this option first make sure that both devices are switched on and then run a network scan from within your phone settings – this will reveal any local wireless networks available for connection. If your security system appears among these options select it and then enter any necessary details in order for the devices to be connected. Once you’ve done this try accessing live surveillance footage; if successful then it means that all components are functioning properly, with no need for further set-up

Test the Phone Connection

Once you have connected your CCTV camera to your phone without an internet connection, it is important to test the connection for functionality. This can easily be done by using your phone’s camera app and performing a few simple steps.

Firstly, open the camera app on your phone and ensure that the camera you are using is selected. If necessary, select it from the provided list of choices. Then aim the camera at an object in front of you and check if you can see its image displayed on the screen. Make sure to capture multiple angles if possible as this will help to verify its functionality.

Once you have verified that you can use the app to view images taken through your CCTV camera, test its durability by placing it in different locations and positions such as indoors and outdoors or low and high heights respectively. Be sure to examine how each angle affects the video quality captured by the device so that further adjustments can be made accordingly if needed. With these simple steps completed, your CCTV camera should now be ready for use without an internet connection!


In conclusion, it is possible to connect CCTV cameras to your phone without using the internet. Depending on the type of cameras, you can either purchase and install special wireless camera receivers or plugs into your home router and view the footage remotely over a wireless Local Area Network (LAN), or use an analog system utilizing coaxial cables that proceed directly from the camera to a monitor. Of course, in such cases, it is important to take extra precautions and security measures like setting up passwords and encryption. Be sure to research carefully which option suits your needs best before making any purchases or decisions.
