How to add a microphone to an IP Camera

How to add a microphone to an IP Camera

Most security cameras that are outdoor rated do not come with built-in microphones to ensure that no water can leak in. This means that you must add an external security camera microphone to these cameras in order to record audio. CCTV Camera World carries microphones for indoor or outdoor cameras. Most IP security cameras with audio input capabilities have an RCA audio connector on their pigtail for connecting a microphone. Some dome IP cameras have a connection block on the inside of the dome. In either case, physically connecting and configuring external microphones to an IP security camera is easy as shown in this guide.

How to tell which camera you have?

In case you are unsure, here's a quick image to help you understand which type of audio connection your IP camera has.

Depending on whether your camera has a RCA or two-wire line in connection, please follow the appropriate section below.

Setup for IP Cameras with RCA Audio Input connectors

What's needed?

Here is what you need to connect a microphone to an IP camera that has RCA audio inputs:

1. Outdoor Microphone (sku 71891) or Indoor Microphone (sku 7100CC)
2. 12V DC 500mA Power Supply (sku 12V5MA)
   You can also use PoE Power Splitter (sku POE101D) with DC Power Splitter Cable (sku DC-PJJ)
3. RCA Male to RCA Male Adapter (sku RCA01)

How to connect a microphone to an IP camera that has RCA audio input

Below is a diagram of how to connect an external microphone to the RCA audio connector on an IP camera.

It is easy to connect a mic by following these easy to follow steps:

1. Connect the microphone to the RCA audio input on the camera's pigtail using a RCA Male to RCA Male connector
2. For longer runs between the camera and microphone you can use an RCA cable with male ends to connect the input and output.
3. Connect the power connector from the 12V DC Power Supply to the female power jack on the microphone.

Alternatively, you can also use a PoE Power Splitter with a 1-to-2 DC Power Splitter to use PoE power for the microphone and camera. Simply connect the PoE cable into the PoE splitter. Then split the power to the camera and microphone using the DC splitter. The data cable for the PoE splitter then connects to the camera for data.

After you have correctly wired the microphone to the camera you can continue to the rest of the article to find out how to enable the cameras audio input for listening and recording.

Setup for IP Cameras with Audio Line-in Input

Some IP security cameras include an internal audio line-in block or a two-wire lead that requires a two-lead connection for connecting a microphone. At first it may seem puzzling how a microphone with a RCA connection would connect to a two-wire input. As an example, in the section below we use a video balun, BNC to RCA connector, and two-lead wire to connect the microphone to the line-in block.

What's needed?

You will need the following items to connect a microphone to a camera with a line-in audio connection consisting of two-lead cabling.

1.   Outdoor Microphone - (sku 71891) or Indoor Microphone (sku 7100CC)

2.   12V DC 500mA Power Supply (sku 12V5MA)
You can also use PoE Power Splitter (sku POE101D) with DC Power Splitter Cable (sku DC-PJJ)

3.   Video Balun (sku VB2PHD)

4.   BNC Female to RCA Male Connector (sku BNCRCA02)

5.   Two-lead Wire for the balun

Best Practices for Using A Two-Way Audio Security Camera

Whether you have a security camera system for a home or business, the need for two-way audio interaction with talk-back capability may arise. CCTV Camera World offers solutions for both one-way and two-way audio. One-way audio is great for listening to sound originating from the location of a camera, but it will not allow interaction with a person at that location. To be able to interact with a person at the camera, the camera would have to have two-way talk capabilities, i.e. a speaker and microphone built-in similar to an intercom.

Two-Way Audio Setup With PoE NVR

Step 1) Connect cameras to NVR

In this guide, we will be using our security camera with two-way audio, sku IP3MPA.  It is a two-way audio IP camera that allows the user to not only listen-in, but also talk back to the person at the camera. These cameras are very easy to connect using the plug-and-play technology. In the video demonstration above we show how easy it is to connect our PoE IP cameras to our PoE NVRs. Simply connect the cables between the camera and the NVR. A single network cable transmits power and data to each camera from the NVR, and plug-and-play technology handles IP address configuration between the camera and NVR without user intervention.

Using a Web Browser for Two-Way Audio

Our camera systems allow the user to engage in two-way talk over the network by using Internet Explorer on a computer or by using our iOS and Android apps for both phones and tablets. First, we will demonstrate how to use the web portal called Web Service in our security systems. A Windows PC running Internet Explorer is required for two-way talk capability through the web browser. To be able to talk-back, you will need to make sure you have a headset or combination of microphone and speaker on your PC to listen and talk-back.

All DVRs and NVRs from CCTV Camera World are network devices and have their own IP address. You first need to connect your security camera system to your network by assigning the DVR/NVR an IP address that fits your network scheme. Once that is complete, you will be able to view your system from a computer or smartphone and use the two-way audio feature over the network. If you wish to view the system over the web when away from home, you will need to set port forwarding rules on your router's firewall to allow remote viewing from the internet.

Once your system is properly connected to your network and port forwarding rules have been created on your firewall, you will be able to engage in two-way audio communication using your smartphone, tablet, or PC from anywhere in the world where Internet is available.

Step 2) How to use two-way talk on Internet Explorer

1.   Open an Internet Explorer window on your Windows PC and type in either your NVR's IP address for local viewing, or external IP address for remote viewing.

2.   Type in your system's username and password, and select Login.

3.   Make sure audio is enabled in your two-way camera by going to Setup and Encode.

4.   Click the Audio Enable check boxes for both the Main and Sub Streams (if they are not already checked).

5.   Select OK to ensure your settings have been saved.

6.   Click the Preview tab to view your camera's live feed.

7.   Select the channel by clicking the quadrant containing the video feed. A green frame will appear around the video feed to distinguish the selected channel.

8.   Select the Speaker Icon in the top-right corner of the selected camera's video feed for one-way audio. This will allow you to hear audio that's taking place at the location of your camera.

9.   To talk back and send out audio through the camera's speaker, select the Microphone Icon in the top-right corner of the selected camera's video feed. You will need either a headset with microphone, or a combination of microphone and computer speakers to listen and talk back.

Now you will be able to listen and talk back to someone at the location of your camera. Note that you will be able to listen to camera audio feeds one at a time - you will not be able to listen to multiple audio feeds simultaneously. Multiple users can listen to one-way audio from a camera, but the talk back function is done by one user at a time.

If a computer is not available to view your two-way audio camera system, then proceed to the next section where we explain how to use two-way talk with a smartphone or tablet.

Two-Way Audio Interaction Using iOS or Android Phone/Tablet

A more convenient way of viewing you security camera system and engaging in two-way audio talk is through your mobile device. The App allows the user to hear incoming audio from the camera and uses the microphone from the phone to talk back, sending out audio through the camera's speaker.

Step 3) How to use Two-Way Talk with a Smartphone or Tablet

1.   First, Open the app (iDMSS) on your iPhone or Tablet (or gDMSS for Android devices).

2.   Select the Menu Icon in the top-left corner, and choose Device Manager.

3.   From here, select the Plus Sign in the top right corner,  Wired Device and then IP/Domain.

4.   Fill out the appropriate credentials of your NVR. You will need to create two entries - one for viewing at the location of your system using Wi-Fi, and second entry for when viewing remotely over the internet away from home. We have a tutorial on how to create entries for both local and remote viewing. After all credentials have been entered, select Start Live Preview.

5.   Select the camera channel you want to engage in two-way audio with by tapping the video feed from that camera, and then press the Speaker Icon. The speaker icon allows the user to  listen to incoming audio from the camera and talk-back sending out audio through the camera's speaker.

Briefly, here is what we did:

1.   Open the dome cover of the camera using the included hex-key tool. Do not use powered screwdrivers or drills or you will damage the dome.

2.   Connect the BNC Female to RCA Male connector to the balun.

3.   Connect the RCA Male tip to the RCA input on the microphone.

4.   Use the video balun to wire in the two lead wire, tighten the screw-downs for the wires.

1. Make sure that you remember the polarity for your wires. We suggest using Red for the positive wire, and Black/Striped for the ground/negative wire.
2. Having a bad connection or the wrong polarity will not record sound or have loud interference.

5.   Locate the small rubber insert next to the Audio/Alarm block and create a small hole for the wires.

6.   Slightly unscrew the screw-down for the Audio-In connector on the block. Insert the positive wire from the video balun and screw it down.

7.   Slightly unscrew the screw-down for the ground connector (GND). Insert the ground wire from the video balun and screw it down.

8.   Run the power cable for the microphone to the 12V DC power supply that is connected to a 220V AC power outlet. Connect the power supply to the microphone.

a)   Alternatively you can use a PoE splitter with a 1-to-2 DC power splitter.

b)   Connect the PoE cable for the camera to the PoE splitter. Then connect the PoE splitter to the 1-to-2 DC power splitter.

c)   Connect the camera and microphone to the DC power splitter connectors.

d)   Connect the RJ45 jack coming from the PoE splitter into the pigtail on the camera.

Once you finally have your camera and microphone connected you can continue to follow the rest of this guide to learn how to enable audio input on the camera.

How to enable audio recording on an IP camera

After everything is connected you must configure the camera to recognize and use the external microphone. This step is extremely important before trying to listen and record a camera. Do not assume that the camera is automatically recording audio when you plug the microphone in.

Using Internet Explorer to enable and modify audio settings

In the video below we show how to use Internet Explorer to login and modify the settings on an IP camera. This process requires knowing what the IP address of the camera is. After that it is as easy as logging in and going to the Settings page. Navigate to the Camera > Audio page. There you will find the audio settings for the camera. You can enable audio for Main-stream or Sub-stream, fine tune the volume settings, and enable the noise filter. Also if a camera has a built-in microphone you can set it to use the external microphone instead.

1080p vs 4K Security Camera

1080p vs 4K Security Camera: Detailed Comparison 

Choosing the right security camera resolution is crucial for capturing clear, usable footage. The debate between 1080p and 4K security cameras is more than just numbers—it’s about finding the balance between image quality, storage requirements, and cost-effectiveness.

Understanding the differences between these resolutions can help you make an informed decision tailored to your surveillance needs.

4K vs 1080p Security Cameras Compared

The resolution is the most significant difference when comparing 4K and 1080p security cameras. 4K cameras, also known as Ultra HD, are higher resolution cameras with a resolution of 3840×2160 pixels.

Such a camera records four times the resolution of 1080p Full HD cameras (at 1920×1080 pixels). This higher resolution translates to superior image quality with sharper, more detailed images.

It makes 4K cameras (vs. 1080p) the best bet for monitoring larger areas or situations where identifying fine details, such as facial features or license plates, is crucial.

However, these sharp images come at a cost—high-resolution 4K cameras require more storage space and more powerful hardware to process the higher volume of data. They also tend to be more expensive regarding initial investment and ongoing storage costs.

Also, 4K cameras may perform differently in low light conditions than their 1080p counterparts, often requiring more light to maintain high image quality.

On the other hand, 1080p cameras offer sufficient resolution for most standard surveillance needs. It is especially true for smaller spaces like front doors or single rooms in multi-tenant buildings. They strike a balance between delivering clear, detailed videos and managing storage and cost more efficiently.

While they may not capture as much detail as 4K cameras, 1080p cameras can still provide high-quality video surveillance for those on a tighter budget or with less demanding surveillance requirements.

In summary, the choice between 4K and 1080p security cameras depends on various factors, including the specific surveillance needs, available budget for purchase and maintenance, and the physical area needing coverage.

Quick Look

Storage Requirements	Lower due to smaller file sizes	Higher due to larger video files
Bandwidth Usage	Lower, more efficient on network resources	Higher, requires more bandwidth for streaming and storage
Low Light Performance	Generally good, depending on the camera model	May require more light to maintain clarity, but advanced models compensate well
Field of View	Wide, but may require more cameras to cover large areas	Wider, can cover larger areas with fewer cameras due to higher resolution
Compatibility	High with most DVR/NVR systems	May require more advanced or specific DVR/NVR systems for full resolution

Application

1080p security cameras are widely used in scenarios requiring general surveillance, including residential areas, small to medium-sized businesses, and indoor spaces where detailed zooming is less critical. They provide a balance between good image quality and efficient storage use.

4K security cameras, with their higher resolution, are best suited for areas requiring detailed surveillance, such as monitoring large public spaces, high-risk environments, and multi-tenant buildings where capturing the finest details is crucial.

They offer superior clarity, making them ideal for facial recognition and license plate identification even over wider areas.

Pricing Options

1080p cameras are more budget-friendly, making them a cost-effective option for those needing comprehensive coverage without breaking the bank.

Their lower price point does not significantly compromise quality, offering sufficient clarity for most standard surveillance needs. The pricing will also depend on various factors, not just the video resolution.

4K Cameras come at a higher cost due to their advanced technology and the better image quality they provide. The investment is justified for environments where the highest level of detail is necessary.

Still, it’s important to consider the total cost, including the need for more powerful hardware and increased storage capacity.

Detail & Clarity

The big difference in video resolution between 1080p and 4k cameras directly impacts the level of detail and clarity. 4K cameras can capture more detail in a larger scene with the same number of cameras, reducing blind spots and the need for additional units. It makes them the best solution for monitoring activities with precision.

Features

While both camera types have various features, 4K cameras often include advanced functionalities such as enhanced zoom capabilities without compromising image quality. Their powerful processing hardware supports more sophisticated video analytics, making them a versatile tool in security surveillance.

Storage and Bandwidth

4K cameras require more storage space and bandwidth (when it is an IP camera) to handle the higher resolution and video data they generate. It necessitates powerful hardware and possibly additional investments in storage solutions.

1080p cameras, with their lower resolution, consume less bandwidth and storage, making them more manageable for systems with limited resources.

Maintenance of security levels CCTV Cameras

Maintenance of security levels at Construction sites through CCTV Cameras! 

There is no sense in denying what is apparent, but a construction site is an area that has constant traffic all day long and sometimes during the night as well. Most managers are often forced to increase productivity levels at the site to meet the requirements of the building owners.

However while completing the construction job on time might be an excellent idea, keeping track of all the activities that occur at the site often provides to be challenging task especially for project managers.

More so, security companies often find it difficult to come up with genuine evidence to back criminal offenses that may occur at the given construction site. With the advent of special technological contrivances such as CCTV security system, managing a construction site has become that much more simple.

See average Number of Security Cameras below:

Project Type	Average Number of Security Cameras
Small Residential Project	4-8
Medium Residential Project	8-16
Large Residential Project	16-32
Small Commercial Project	8-16
Medium Commercial Project	16-32
Large Commercial Project	32-64
Industrial Site	32-64
Infrastructure Development	64+

Benefits of Installing CCTV Systems:-

1. Monitor construction workers

One important benefit of installing CCTV systems at the construction site is that it allows the project managers to have a better view of the employees` activities. To be specific, the construction site is often a beehive of activity, which can sometimes pose a challenge for managers who are supposed to account for everything.

In the past, the managers would have to rely on unreliable reports from their subordinates or perhaps spend hours going around the entire site to determine the worker’s activities. This was a highly unreliable method, and CCTV cameras provide a better solution for such a complication.

In fact, construction managers can monitor their employees work rate levels by watching recorded or the live footage that is relayed by the cameras.

2. Evaluating the site

Besides that, another important benefit of installing these types of cameras at the constructions site is that it provides the managers with a better option for viewing the progress of the entire site. It’s important to note that CCTV footage along with individual devices such as drones are often used to determine the progress of a given construction project. Managing the site is highly important since it allows the managers to determine whether additional resources such as skilled labor or resources are needed to complete the project.

While the manager might still have to visit the site for first-hand observation, the CCTV cameras are also convenient since they provide footage of how the events at the site have been unfolding.

3. Determining resource usage

More importantly, the CCTV systems can also be used to determine the level of resource usage at the construction site. This is because the level of activity at the site of often so high such that the construction manager cannot be able to account for resource usage at the scene fully. Some of the resources that need monitoring include cement, hardware tools and employee gear amongst many others.

With this types of systems, the manager can easily determine where any inconsistencies or perhaps where there was any illegal activity occurring at the site and therefore deal with it as soon as possible. As a result, the manager is better at accounting for resource usage or perhaps identifying any project setbacks on time.

4. Help improve security at the site

One of the biggest hindrances that most constructions projects face is the maintenance of security levels at the site, especially when no one is watching or perhaps when the site has been dormant for a while. For security companies, the footage can be used to determine any inconsistencies or perhaps any illegal activities that may be taking part at the site.

The footage always provides an excellent perspective when it comes to settling security complications in criminal cases. By installing CCTV security systems at the scene, construction managers can determine any form of illegal activities or perhaps the theft of costly resources that are used for the completion of construction projects.

While the presence of security cameras is often enough to deter the vast majority of would-be thieves and vandals, you will have access to the video evidence required for successful prosecution should trespassers ever infiltrate your site. Not only are CCTV cameras more cost-effective security solution than man guarding, but you can also access live footage around the clock remotely via the internet should you ever wish to.

Given all these points, when it comes to managing an entire construction project, there is barely any space for poor decision making or perhaps insufficient improvisation. It’s imperative that you take the time to make an informed decision for the development of your project and this often includes settling for the superior benefits of CCTV systems. Although these types of security systems might cost a significant amount to install, they are crucial towards the completion of the entire project are therefore a feasible investment for any given construction project.
