The ability to record audio makes the tracking device a comprehensive security equipment. Connecting a separate microphone may cause compatibility and setup issues. Cameras with a microphone simplify installation: an external recording device may require a separate power or signal line.
Pay attention to models with a built-in Wi-Fi module, the installation of which comes down to fixing the device and connecting the power. Despite the higher price of video cameras with a microphone that work through wireless transmission data, this solution allows you to save on the laying of communication lines and installation work.
Two way communication
With a built-in loudspeaker, the camera can be used as a video intercom, allowing you to communicate with the visitor. This feature is required when the equipment is in baby monitor mode.
The price of cameras with a built-in microphone in Moscow
The Amik online store cooperates directly with equipment suppliers, being the official partner of well-known trademarks. Affordable cost is provided by direct deliveries of goods from the manufacturer's factories.
Which model is suitable for home video surveillance?
In this case, we recommend devices with a built-in microphone and speaker. Pay attention to the Bestseller - Dahua DH-IPC-K15P. This compact wireless digital camera delivers 1.3 MP resolution with a sensitive 1/3 size CMOS sensor. The manufacturer used high-quality materials and components.
Sometimes the audience from this site stimulates searches and possible options"bend" the system. Somehow I wondered about installing a video surveillance camera at my father's tire shop, where there is no wired Internet in principle. Then I was advised not to go into someone else's channel and hire professionals. So I turned to them and received a response in a tidy sum for the equipment, hard drive and installation. But what Russian doesn't want to do everything cheaply? Thus, an IP camera was found in the open spaces of aliexpress, which performs all the functions that needed to be obtained. And the Internet will be obtained using an old 3G modem from MTS.
This camera allows you to perform tracking using a motion sensor, record Full HD video, shoot in the dark and be controlled using a smartphone.
Let's go!
Additional Information
I looked at reviews of similar cameras on youtube and the choice was made on the opinions of others. After all, all I needed was not constant surveillance and recording, but viewing at any time.
Let's go to the standard start. Package. Square in white-blue coloring with nice printing. The front side shows the main features of the camera.
The back part has a QR link to download the application, a password and login to access the browser interface and some technical information.
The strangest thing is the presence of various plugs on the power supply, which are indicated on the bottom of the package. I didn't even see it right away!
There are 4 variations in total: UK, EU, AU, US. I am glad that you don’t have to look for any adapters.
The complete set is the maximum for installing the camera anywhere, they put in the box:
- IP camera with antenna
- Vertical bracket for wall mounting
- Power Supply
- User manual
- 2 dupelshurups
To power the camera, a power supply with a European plug for 5V and a current of 2A is used. An NP plug is used to connect to the camera.
The length of the wire upsets, it is too short - 1m. Therefore, you either have to lengthen the wire, or bring out a special outlet for this, well, or use a carrier.
The fastener is made of ABS plastic, consists of one plate attached to the wall and a hinge for tilting. Plate height - 10 cm. Hole diameter for screws - 4mm. To install the camera, there is a platform with a hole and a "lamb" with which the camera itself is screwed (it has a thread).
The instruction itself English language she tells us about possible connections both using a WiFi antenna, and using a "holy" cable with RJ45. We will talk about the connection itself later. In general, if you have any questions about connecting the camera, but you do not want to read the review, then everything is there.
Let's take a look at the camera itself. Appearance it does not differ from most IP cameras and in its arsenal has a swivel "head" in two planes. The case itself is completely plastic, the color is white and not the most convenient for disguise.
In the lower part there is a podium with electronics and a motor. Also in front we have the name of the manufacturer - EasyN.
A 1/2.5"" CMOS sensor is used as a photomodule. The maximum resolution is 1920*1080 pixels. The focal length is 3.6mm.
The swivel head consists of a protruding lens, 8 infrared LEDs, 1 motion sensor (black dot above the lens) and a microphone under it all.
The vertical tilt angle is 0°~120°. The camera can be programmed to automatically tilt, or do it manually from the smartphone screen.
Basically, such a large degree is needed after installing the camera on standard fasteners.
At the base of the swivel head, a speaker grid was placed. Through which there is a sound accompaniment about the disconnection, if the hooligans want to cut the cable.
The dimensions of the antenna are 15cm.
On the back wall there is a system panel with communications, from left to right, a reset button, an RJ45 connector, a swivel antenna output, a TF card slot (the maximum supported volume is up to 128GB, my 64GB card “haws” easily) and a DC connector for connecting a power supply.
On the bottom there is a perforated cooling pad, a duplicate sticker with a QR link and other “administrative” information. Also in the center is a thread for mounting on fasteners. If you decide to leave it on a flat surface, then there are foam rubber legs at the base.
The camera has an almost circular angle of rotation around its axis - 355°. At the same time, turns are not accompanied by any noise and the sound of the motor. But there is sound from the motion sensor on the video. At the moment when the camera catches movement, the recording starts, which is accompanied by a sound signal - a squeak.
To connect and configure the camera itself, you need a smartphone and proprietary software. To download, follow the QR link to the market and install it. After installing the application, we turn on the camera in the network and it makes a full turn along 2 axes and starts to make loud music. The instructions say that in order to stop the music you need to do the following:
1) Connect the camera to the network via WiFi
2) Disconnect the camera from the 220v network
3) Connect the camera to the network with a cable
Therefore, while the connection to the camera is in progress, you will be accompanied by loud music. Deal with it. Also, if the camera loses connection with the network, the music will start playing again.
The first launch of the program and in front of us is a window with our camera, but if we have several cameras, then all the rest will be there.
To go to the properties of the camera, you need to click the gear. After that, an additional window opens in which:
1. View camera list
2. Recording of all events from the motion sensor.
3. View the photos and videos you have taken
4. Go to settings
5. Removing the camera
But the tinctures themselves are represented by many variations of the camera. I'll just highlight the most important ones:
1. Password Manage - the first point that you have to visit. After all, it’s impossible to log in normally with a camera with a regular password.
2. Image Setting - allows you to adjust the brightness and contrast of the camera, enable mirroring horizontally and vertically, as well as set the operation of infrared illumination (always on / off or automatically)
3. Event Setting - motion sensor setting. You can turn it off completely, as well as adjust its sensitivity, and choose the notification method on your smartphone. Here you can set the saving of the fragment to the memory card.
4. Full Time Record - I didn’t particularly understand this item, a function for streaming video with its own settings.
5. Cruise - automatic rotation function on 2 axes. Here we set the speed of rotation and the starting point.
As you can already understand, the camera has a lot of settings. But the above is not all. The following settings open when you turn on the P2P camera itself. The "desktop" looks like this: the "top bar" displays the current browsing speed in Kb/s and the traffic spent, the quality of the shooting, the resolution and the number of frames.
A window with a camera preview is displayed in the center, by the way, you can control the camera with swipes and tweaks to zoom in and out of fragments. The "bottom bar" allows you to turn and tilt, turn on the microphone built into the camera and hear the sounds of the room, as well as transmit your voice commands to the built-in speaker. You can enable automatic cruise in one of the planes, as well as create your own preset for use depending on the situation.
Of the additional functions and settings, this is the start of recording a video or photo, the choice of shooting quality (when the quality changes, the resolution changes)
The maximum is 1920*1080, the average amount of traffic spent at this resolution is 70-220k/s.
The average is 640*352, the average amount of traffic spent at this resolution is 25-35k/s.
Bad - 320*176, the average amount of traffic spent at this resolution is 5-10k/s.
For those who want to use the camera without the participation of a smartphone, EazyN has released a proprietary utility for Windows. The settings are still the same. Easy PC control.
Of the features of the operation of the camera itself and the built-in motion sensor, this is the fact that the camera, when the latter is triggered, records short segments (mostly up to 25s) with a quality of 640 * 352 and this quality cannot be increased in any way.
Since this camera was purchased for the purpose of viewing, and not catching movement, then 2MP with their FullHD will cope with all tasks. Leaving on a business trip, I decided to test the camera on my cat. Since this furry creature eats a pack of food in 2 days, it was decided to leave the camera to monitor her food bowl ... In the meantime, look at a typical day of this animal.
The transition from conventional lighting to infrared occurs quite quickly and without slowdowns. Photos taken with or without IR diodes please with detail and overall quality.
Definitely for the money that the camera is now being sold (and this is not much cheaper than I took) good camera. Whether you need to keep an eye on your house while you're away or watch your car out the window, this camera will do the trick.
On a 5-point scale, I would give it 4, and then because of the inability to increase the quality when shooting with a motion sensor. The rest suits me perfectly!
By the way! Back in the summer, I installed lamps with a motion sensor in the house for my parents, there are no reviews on them yet. Anyone interested in this topic?
I plan to buy +16 Add to favorites Liked the review +14 +23IP cameras with speakers are well suited for monitoring offices, warehouses, shops.

IP camera with motion sensor CD310 is designed to work with CamDrive cloud video surveillance service. The CamDrive service allows you to effortlessly organize equipment settings effective system video control.
MOTION DETECTION (PIR SENSOR)
The CamDrive CD310 camcorder is equipped with a built-in IR motion sensor. The motion camera is triggered instantly and, upon a signal from the infrared detector, turns on the video recording in the archive and / or sends an alarm message about movement in the selected area. For example, in case of penetration into a room with a CamDrive camera installed, you can immediately receive a notification by SMS or e-mail about this fact. A motion sensor camera is actually two systems in one: an online video camera with a "cloud" archive and an alarm system with video confirmation of events.
BUILT-IN ACTIVE MICROPHONE AND SPEAKER
CamDrive CD310 is a multifunctional IP camera with microphone and speaker. An active microphone built into the camera allows you to both "hear" what is happening in real time and record sounds in the camera's coverage area in the archive. The acoustic coverage area of the microphone is 10 meters. The important characteristics of the microphone are its high sensitivity to quiet sounds and the low level of extraneous amplifier noise, which makes it possible to transmit sound with virtually no distortion.
The camera is equipped with a high-quality speaker - in one click you can send audio messages from the application or from your computer to the camera. Possibility of two-way audio communication favorably distinguishes this model from competitors. The function of transmitting audio through an IP camera with a speaker from a personal account or application is useful not only in everyday use, but can also greatly help in emergency situations in the surveillance area.
NIGHT VIEW (IR LIGHT)
When the level of illumination in the surveillance area falls, the camera automatically switches to night shooting mode, and the camera's built-in illumination in the infrared spectrum invisible to the human eye turns on. Night shooting mode allows you to get a high-quality picture from the camera even in absolute darkness.
USING CAMDRIVE HOSTING SERVICE
The CamDrive online access service provides not only the ability to monitor events in real time from anywhere via the Internet, but also the storage of video recordings on remote servers, which eliminates accidental or intentional data corruption in the case of local storage of the archive. A video camera with a speaker only needs to be connected to the INTERNET network and connected to the power supply - in the purchase of additional equipment or the installation of a specialized software not necessary.
WORK IN DIFFICULT LIGHTING CONDITIONS
Expansion technology dynamic range(DWDR) allows you to make a video recording of a high-quality image with uneven illumination of objects in the frame. For example, if the camera is pointed at a light source, and an object located between the light source and the camera lens enters the field of view, a backlight effect will occur - it will be difficult to see the details of both the object itself and the space behind it. DWDR mode allows you to minimize backlight - brighten dark areas of the frame and darken overexposed areas, thus you get a high-quality image even in difficult lighting conditions.
VIDEO ARCHIVE
An IP camera with a built-in microphone and speaker, coupled with the CamDrive service, provides the ability to conveniently select a fragment recorded in the archive for playback and download. You can choose the recording method yourself in your personal account: constantly, according to a schedule, or when the camera starts to work on motion. Install a miroSD memory card in a special slot and you will not be left without video recording even in the absence of the Internet. All video data will be saved to the card, and when the connection is restored, automatically transferred to the "cloud" archive.
CONNECTING AND INSTALLING THE CD310 IP CAMERA
Video camera CD310 - smart IP camera with speaker and microphone! To connect, no settings are required - you can easily do it yourself without resorting to the help of contractors. The camcorder has 2 connectors on the rear panel. Just connect the plug from the power supply to one connector, and the Internet cable to the second connector. It remains to enter Personal Area to view live broadcasts and recordings from your camera.
STORING INFORMATION ON REMOTE SERVERS
A "cloud" archive is a dedicated place on remote servers where video from a camera is recorded. The archive is obligatorily encrypted and repeatedly duplicated, due to this, data loss or damage is excluded. CamDrive allows you not to think about organizing data storage or online broadcasting from your cameras and makes it possible to build a video surveillance system on your own in a few minutes using a regular browser from a desktop computer, laptop, tablet, and even mobile phone from anywhere in the world via the Internet.
The use of audio equipment in video surveillance systems is not very common. Although its use significantly increases the effectiveness of security systems. In addition, it becomes possible to conduct interactive negotiations.
Microphones integrated into video cameras are one of the easiest ways to use audio equipment in video surveillance systems. The intrusion detection efficiency of such a system increases. The coverage area of the microphone is much wider than the capture area of the camera lens, it averages 180°-360°. In this way? the detection range of a video camera with a microphone is significantly expanded. It is most effective to use these devices in combination with remote control systems for PTZ devices. Having determined the source of the sound, you can direct the ptz camera to the suspicious area.
In addition to listening, an IP camera with a microphone and speaker can be used to address visitors or intruders. Such actions of the security system are preferred. It is much more important to prevent damage to property and material losses than to demand compensation from the attacker later. For example, finding a restricted area or suspicious activity near an ATM can be warned by a security guard at a distance.
In some cases, using interactive communication through a camera with a microphone, you can provide assistance and support to an injured person, warn him that help has already left or provide advice.
The scope of the audiovisual security system continues to expand rapidly. This may include remote control of access to the territory, interactive technical support, remote control of physically unguarded objects, and videoconferencing.
Audio track technical support equipment
Naturally, audiovisual communication components are easier to install in systems digital video surveillance than analog. Even with the use of modern analog cameras with an integrated microphone, it will be necessary to run additional cables to transmit the audio signal from the camera installation site to the DVR. In addition, the long distance between the audio signal receiving device and the microphone makes it necessary to use balanced audio equipment, which further increases the cost, complicates installation and operation. Unlike analog, in a digital audio system, a video file and an audio track superimposed on it are transmitted over one twisted pair.
Many network cameras have either a built-in microphone or a built-in microphone connector. The latter are preferable to use if there is a need to use high-sensitivity audio equipment. Line-in audio inputs on cameras are compatible with modern microphones of any type. In addition, if the microphone is placed separately, it can be installed at some distance from the video camera in close proximity to the sound source. This installation method allows you to use two-way full duplex mode without fear of echo.
If you need to use an IP camera with a microphone for interactive communication, you can purchase a model with built-in speakers, or you can use network video equipment with audio support and connect a separate speaker. In this case, preference is given to active speakers with a built-in amplifier.
Important! To minimize noise interference, it is recommended to use a shielded audio cable, and avoid running it near power cameras that transmit high-frequency signals. The audio signal should be transmitted as short as possible. Otherwise, you will need to use balanced audio equipment, i.e. use a balanced shielded cable, microphone and amplifier.
Audio transmission modes
Depending on the place of installation and the tasks set, it becomes necessary to various ways sending an audio signal. The use of 3 audio communication modes is practiced:
— sound transmission mode in one direction. The audio signal is transmitted from the camera to the DVR. As a rule, the mode is used in security video surveillance systems. However, in this mode, it is also possible to transmit sound back from the operator to the speaker of the video camera. This method has limited use, but can be used quite effectively to scare away criminal elements from the place of protection.
- the sound can be broadcast in both directions, but only in turn. 
- the mode is completely similar to the usual telephone conversation. However, its use requires the use of a camera that supports the corresponding sound card. 
Sound processing
Just as the video signal is processed by special codecs to reduce its size while maintaining the original quality data, the same procedure must be carried out with the audio signal.
The analog audio signal that the microphone receives is digitized. The process is called discretization. The file size is then reduced for fast transfer and storage. This conversion is done by the audio codec.
Sound quality is characterized by the sampling rate. This parameter means the number of parts of the analog audio signal taken for digitization in one second. Accordingly, the higher the sampling frequency, the better the sound quality will be at the output. However, it should be remembered that this will require more memory, as well as wider data transfer channels. The average audio data rate is typically in the range of 32...64 kbps.
Modern progressive audio codecs that are used in most camcorders with a microphone:
- AAC-LC is an audio codec built into the MPEG-4 compression algorithms. It has a sampling rate of 16 kHz and a low level of complexity, respectively, the quality of the resulting sound is the highest. For its transmission, a channel of at least 64 kbps is required
- 711 and G.726 are open source codecs with a medium sampling rate and an efficient conversion algorithm.
Additional functionality of a surveillance camera with a microphone
Many camcorders with a built-in microphone have an alert feature when sound is detected. Its most effective use is in combination with a hardware or software motion detector. This feature will be especially useful for responding to rooms that are too dark for visual control. Dome camera with microphone when detecting sound, such as broken glass, voices in the room. Starts capturing and transmitting video and audio stream to the DVR, which can send emails, turn on notification devices. Many ptz camera when sound is detected, they can turn on the function of moving to preset positions.
The video stream and the accompanying audio file are transmitted over the communication lines in the form of two separate data packets. In order for the receiving device to be able to synchronize these two packets, each of them has a timestamp. On the this moment the most advanced codecs in which the Microsoft Direct X synchronization system is built-in are JPEG-4 and h.264.
