Wireless data transfer to PC or mobile device is one of the basic functions available on a Wi-Fi-enabled camera. Typically, to send pictures you need to set special application, with which you can conveniently select and sort pictures on a memory card, change their format and resolution before sending to another device.
One-touch communication
Some modern models cameras have a built-in NFC (near field communication technology) module, with its help you can instantly install Wi-Fi connection between devices and transfer pictures with one touch. Working with NFC is supported in the OS Android versions 2.3.3 and higher.
Remote control
You can control your Wi-Fi enabled camera remotely! For example, using a smartphone, on the screen of which the image captured by the camera lens is displayed. This is very useful when shooting self-portraits and wildlife. You can remotely not only press the shutter button, but also select the focus point, zoom the frame, adjust the exposure, and so on. Kit available settings depends on the camera model. The remote control feature may be most interesting to photographers who shoot on a tripod, as it is important to keep the camera position securely in place.
Posting photos on social networks
Sending photos by e-mail is another one basic function cameras with Wi-Fi. Pictures can be sent directly from the camera to e-mail to the selected recipient and via a mobile device. Similarly (in two ways), you can share captured footage in in social networks. Some have a built-in function for posting on social networks, which allows you to change the resolution of pictures and add comments to them. The number of available social networks depends on specific model or a specially installed application.
Backing Up Photos
Using Wi-Fi and a special mobile application, you can set up automatic backup of photos from the camera to a laptop or mobile device, as well as uploading them to the popular cloud data storage: Dropbox, Google Drive, Microsoft SkyDrive or any other.
Designed for automatic, fast and convenient wireless transfer of photos and videos taken with a camera to a computer. Usually, even if the camera is equipped with a Wi-Fi module, you still have to do a whole bunch of different body movements to transfer content from the camera. And if it’s not equipped, then it’s not an option at all. When using an EyeFi card for any camera, you don’t need to do anything at all: if the camera is within range of a registered Wi-Fi network, and the card owner’s computer has, then everything that is recorded on the card flies to the computer, and, if the owner wishes, also to the EyeFi cloud.
I've been using these cards for a long time. This is very convenient for me for photographing gadgets for reviews: I photographed everything, returned to my work computer, and within a few minutes the photos were uploaded to the hard drive.
True, the previous card, which worked quite well with the camera, for some reason did not work with the camera, so I lived without this card for some time and I was pretty tired of taking the card out of the camera after each shoot and inserting it into the computer reader. (Yes, Olympus has its own Wi-Fi, but it is designed for sending content to smartphones and tablets, and besides, this is all quite inconvenient.) Recently I decided to see what EyeFi is doing there now - maybe there is some a new option that will allow you to return to the “take it off - it will arrive on its own” system. I looked. They now have a top card there - eyefi mobiPRO. Judging by the description, it does exactly what I need. But at the same time, for some reason the Shop Now link directs you to purchase a Toshiba 32GB FlashAir III, and I’m not very sure that this is exactly what I need. I went to Amazon and found the Eye-Fi Mobi Pro 32 Gb WiFi, and it also came with an annual subscription to their cloud with an unlimited amount of photo and video. Cost €74, and there were only two in stock - this option is no longer available. This thing arrived and I studied it. Here's the packaging. 
Inside is the card itself, a USB reader (a handy thing, by the way, I use it for all other SD and microSD cards), a card with a code. (Previously, no codes were required, but now they have been introduced - apparently because of the cloud.) It connects very easily. The application (iPhone, Android, desktop) is downloaded and installed from the site; in the application you need to select Add an EyeFi Mobi Card, after which you need to enter the code from the plastic card. Next, the card appears in the application and needs to be connected to
If you register in the cloud and connect it, then the pictures are also automatically sent to the cloud (there are no restrictions if you have a subscription), and from there they are available for any connected devices with your login - desktops, smartphones, tablets. It is very comfortable.
By the way, I looked at how much their unlimited cloud for photo and video costs - it turned out to be €50 per year or €5 per month. Well, it doesn’t seem to be that expensive, but Google seems to provide a similar unlimited cloud for Google Photos for free, I’m just now learning how it all works. But in in this case
It’s not a matter of the cloud, but the fact that with such a card, everything from the camera automatically flies to the computer. This is exactly what I needed and it all works great. The adapter won over with its reasonable price compared to Transcend WIFI SD, PQI Air and Eye-Fi. In general, this adapter is positioned for the purpose of quick access
to the footage in a camera or video camera. As it later turned out, you can ONLY download photo and video files via wifi.
Photo formats: JPG, PNG, BMP, RAW, CRW, DCR, MRW, ORF, RAF, X3F, NEF, KDC, PTX, PEF, CR2, TIF, MOS, K25, MEF, MPO, SRF, SR2, DNG, ARW , RW2, BAY, DCS, DRF, NRW, RWL, SRW, 3FR
Video formats: AVI, MOV, MP4, MPG, MTS, ASF, 3GP 
It came in beautiful packaging with high quality printing. The inside of the box is reinforced with plastic. The seller included a "thank you letter". 
And here is the culprit of the review herself The write protection tab is integral with the body and is in the “Write enabled” position. On back side
alternative markings for Lzeal DS100 are discovered.
The main advantage of the software is the Auto-Push function, in which all new files will be automatically uploaded to local storage on the client.
It is convenient to use this in a photo studio. I took a photo, and the freshly photographed face was immediately uploaded to the computer without any unnecessary movements.
In the Android version, the downloaded photo can be immediately processed in full. The list of effects and features is amazing. There are more of them than on Instagram. You can also view all EXIF parameters. To view photo and video material, it is proposed to use two different pages
"Photo gallery" and "Video gallery". Which is a little inconvenient. Then you can go straight to required folder
, if there is more than one. So we got to page-by-page viewing of 16 sketches. 
Not everything is so colorful in the video gallery, there won’t be any thumbnails and it’s winter too 
For detailed information, you can view the photo in full screen. 
You can download files in three ways:
- files separately
- selected files from one thumbnail view page
- entire folder
If you download separate file RAW or AVI, then the speed is limited to 1750 KB/s.
When downloading as an archive, the speed is up to 1700Kb/s.
To download a file of an unsupported type, you need to change the extension to one from the list of supported ones, then it will be displayed in the corresponding gallery and you can download it. Here's a trick with the ears.
Well, for dessert, as promised
nudity
There was no desire to disassemble, so in the rays of X-ray 
Pros:
+ the ability to instantly transfer photos from your camera to your phone.
Minuses:
- You cannot delete or upload files to a flash drive;
- You can download only supported photo and video formats;
- Slow speed downloads
P.S. For some reason, the TD did not start in the SD connector on Dell 27" and 30" monitors. Although the contents of the microSD on the computer were displayed.
P.P.S. I urge you for help in breaking this miracle micro-NAS router. I've already tried all sorts of tricky requests via the web interface. It looks like the web interface was not written by Indians.
I'm planning to buy +88 Add to favorites I liked the review +84 +168Recently, the prevalence of Wi-Fi cameras for video surveillance has increased. Thanks to their wide functionality and ease of use, analog devices are gradually being replaced by digital ones. Among IP cameras, the share of wireless devices is increasing.
Wi-Fi camera device
A wireless camera is digital device for video surveillance with information transmission via Wi-Fi. Based on their design, IP cameras are divided into dome and box cameras. In the first case, the lower part is covered with a transparent plastic hemisphere, providing additional protection equipment. The second type is placed on a special fixed or rotating bracket.
According to the permissible location, equipment is divided into internal and external. The design of external cameras allows them to operate in a wider temperature range. Such devices are protected from dust and moisture, in most cases certified to IP66 or IP67. Thanks to this protection external cameras can work in difficult climatic conditions. When using a special protective casing, it is possible to install indoor equipment outdoors.
When choosing an outdoor Wi-Fi camera, consider the protection class and operating temperature range. Equipment without IP67 protection is damaged by moisture entering the housing. Majority wireless cameras is used for open installation , but the design of some models is suitable for installing them covertly. Basically, IP cameras without IR illumination are used for this. external antenna
. LED backlights can attract attention, so they are not always suitable for hidden devices. Among the common brands are Hikvision, VStarcam, Dahua, Foscam. Companies specializing in network equipment
, for example, TP-Link and D-Link. Many large electronics brands (Samsung, Logitech, LG) also operate in the wireless video surveillance market.
- Depending on the model, the equipment used may have various additional interfaces:
- Connector for connecting an external microphone.
- Input for external sensors and security alarms.
- Output for connecting audio devices. Ethernet connector for wired connection
- to the network (works as an alternative to a wireless connection).
- MicroSD memory card slot. Connector for external Wi-Fi
antennas.
Key features of Wi-Fi cameras IP cameras connect to existing local network via router. Typically used for this WPS protocol (Wi-Fi Protected Setup), synchronizing devices by pressing special buttons on them. Initial setup network connection
also possible via USB or via an Internet cable, if appropriate interfaces are available.
Devices can support PTZ (pan, tilt, zoom) technology. It allows you to rotate the camera along the horizontal and vertical axes, as well as zoom in on a certain part of the image. Pan, tilt and zoom operations are usually performed in the same window through which video and audio are broadcast. To access, use the web interface or a separate application. Wi-Fi cameras are often equipped with infrared illumination, consisting of several LEDs around the lens. It can illuminate objects at a distance of 5 to 50 meters. Switching on is done in manual mode
Important! Although the human eye cannot distinguish infrared radiation, part of the backlight spectrum may be in the visible range. Because of this, turned on IR LEDs are visible by their dim, dark red glow.
Some devices are equipped with a feedback system. They provide the opportunity not only to receive information, but also to transmit audio to reverse direction. To do this, use separate speakers or a speaker built into the IP camera. This technology works in offices and production premises for transmitting voice instructions to employees. Also popular home use as a "video baby monitor".
Advantages of Wi-Fi cameras
Ease of connection, possibility remote access to the video stream and the presence of feedback are the main advantages wireless devices for video surveillance. Connecting Wi-Fi cameras does not require laying a separate cable to transmit information. As with wired IP cameras, data is exchanged via the Internet, so the broadcast is available from anywhere in the world. To connect, just enter your IP address, login and password.
Another advantage is the wide functionality software wireless cameras. When motion is detected at a protected object, the device can send the user an SMS or email message. Selected models They also allow you to set up face recognition and notifications about changes in the state of connected sensors.
Video recording from IP cameras can be saved in cloud storage. For this, Ivideon or other similar services are used. They can be either free or with a paid subscription. It is worth noting that not all devices have the ability to connect to the cloud. If such a function is needed, check its availability before purchasing the equipment.
Some IP cameras have anti-vandal protection. It is provided by a one-piece body made of materials with high strength. The surface of the case is also coated to prevent scratches.Note!

Disadvantages of Wireless Cameras
The main disadvantages of Wi-Fi cameras: vulnerability to wireless network interference and the possibility of signal suppression. When slow or unstable internet connection viewing the broadcast will be difficult. Moreover, if to remove wired camera out of order, direct access to it is required, Wi-Fi camera can be neutralized remotely using a signal suppressor.
An attacker can notice the antenna that such devices are often equipped with and turn on a “jammer” to create interference in the 2.4 and 5 GHz bands. Wireless transmission of images and sound will become impossible. The only way to avoid losing recorded data is to use cameras with parallel storage to a memory card. As a rule, MicroSD cards are used.
Another disadvantage is that the devices are not completely wireless. Despite the fact that information is transmitted via radio, a cable connection is required for power. Models with a battery are not so widespread; they are mainly used as wearable devices (chest cameras and video recorders).
