Digital Cameras / Camcorders

A digital camera or digicam is a camera that encodes digital images and videos digitally and stores them for later reproduction. Most cameras sold today are digital, and digital cameras are incorporated into many devices ranging from PDAs and mobile phones (called camera phones) to vehicles. Digital and film cameras share an optical system, typically using a lens with a variable diaphragm to focus light onto an image pickup device.  Digital cameras can display images on a screen immediately after being recorded, and store and delete images from memory. Many digital cameras can also record moving videos with sound. Some digital cameras can crop and stitch pictures and perform other elementary image editing.

I would like to know if I am buying the right SD card for my DSLR Canon T3i. In the chart attached from Amazon it states that my CPU has to have 128GB of RAM. I only have 16 GB. Does that mean I will not be able to use the card to transfer content of the SD card onto my PC. Also what should I look for when buying a SD card? There are so many numbers on it . It gets confusing. Class 10 , The read/write speed, UHS class I, III. I just need something with large capacity and fast transfer to my PC . Also does the image quality of pictures or video depends on the camera it self and NOT the SD card. Please help me.

Thank you,

Basem Khawaja

Hello Experts,

I am looking for a camera streaming solution over the Internet. The cameras will be installed in a remote location with limited bandwidth (1 Mbt)

Does anyone know of a good solution?

CameraCameraHow can I connect a microscope camera wirelessly?
I am looking for an indoor security camera that will work in a location that will not have access to Internet or a WiFi network.

Furthermore, the camera will need to record video, on motion detection, and store to a SSD memory. Downloading the video should be possible via a local hotspot connection with an Android or iPhone.

The Problem: This may seem like easy requirements but I am tested about five cameras now and found that all of them require a WiFi connection to operate. :(  
The one camera that works without WiFi is an inexpensive "hidden camera" model: 
Unfortunately, this camera isn't acceptable for my requirements. Why? Mostly because the field of view is extremely narrow (about 90 degrees or less).

I think that a solution to this question will help others because I am confident that I'm not the only person who has a need for a recording security camera in a location without WiFi or any form of Internet connection.

My requirements:
- Must be a dedicated single-use security camera.
- Must be designed to be wall mountable.
- At least 720p but higher resolution is better.
- Dome type configuration is ideal.
- Must be a single stand-alone camera with a power (AC or DC) connector.
- The field of view should be about 110 degrees. Although, I suspect that 110 degrees may be a 4K resolution camera (acceptable as long as it's under $250)
- SD memory storage (at least 32GB).
- Cell phone app to …
Need to easily make a composite matrix of images

I have roughly 20 images of faces I need to make into a composite. Think Brady Bunch...

4 rows, 5 columns...

But I do not want to need to reduce the size of any image. I want it to auto adjust to fit.

Suggestions for a tool?

Word has a table layout where I could drop each photo. But there will be white space. I instead want this to look like one image with 20 faces.


It need to be easy...

I have a json file "inventory.json" file that I am trying to show in an xamarin android listview but am having trouble understanding the adapter.  Here is my code which is throwing this error:  Newtonsoft.Json.JsonSerializationException: Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List`1[ProfilesScan.Model.SelectInvItemlist]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.

Need to create a Mac Based Image Library

I have thousands of photos of all sorts, and need to build an automated search where I can add attributes and pull up images which satisfy my search criteria.

These are not modern photo's of people, so face recognition is not relevant. Photos are of buildings, maps, historical details, and a few faces, but even those are not usually photographs and tend to be paintings.  So, no face rec.

Also, these are my own private images and do not warrant a cloud solution. Privacy and being able to protect my datas is more important to me. BUT, I would consider using an Azure solution, IF I also had total access to my images with no Internet connection. (I do want some exposure to Azure, as a .NET Developer)

What tools exist that are configurable for this?

I need to add as many attributes as I would like. I need the search tool to reconfigure to include a new attribute.

I am a .NET Software Engineer, so a bit of coding would not scare me.

I would not be afraid to use a cloud solution IF I could also be able to ensure I have the ability to run it locally on my MacBook. My images are controversial, and could cause the master of the universe to try and cut my account...

What about a WordPress plug-in? I would host WP on my Mac if required for this.

I am trying to find a tool (or tools) I can use that will save me a world of work.

After doing a lot of research we decided to go with Hikvision for our CCTV security system. It seems like they are one of the major players. We kind of hit a snag with the computers we monitor the cameras on. We can view maybe 6 cameras simultaneously but the CPU usage at that point runs a constant 80% and is very, very taxing on the computer. Is that normal at the 6 camera mark?

   We were told by their support early on (about 8 months ago) to alleviate this issue by running all the cameras in sub-stream. That solved the issue for 8 months until the other day. I added a camera and everything went to pieces. Half the cameras would not reconnect. Don't know what changed but when I called Hikvision support they determined that the Lorex cameras we started out with couldn't be ran in sub-stream and needed to run them in main-stream. It seemed to work but why, after running fine for 8 months in sub-stream, would the Lorex camera no longer be able to connect when in sub-stream?

   So we changed the Lorex cameras back to main stream and the CPU usage re-reared its ugly head. I called their support and was told that more memory would drastically improve the situation. I called a second time and was told a Video card would drastically improve the situation. Alas on a third call I was told neither would really help. Well I double the memory from 8 to 16GB and put in a nice little Radeon HD6450 with 1GB and unfortunately my third call in was correct. Neither really helped.

We have a Canon PowerShot SD300 and when it is turned on we see the menu for entering the date.

Generally speaking in what mode does a camera have to be set so that when connected to the computer the images are imported.
What software program can do something like the below
since I want to take multiple photos on my camera,
then reduced MB size before emailing them ?

 1. Select all files in one directory (C:\pictures\........)
 2. Click compress
 3. Keep original photo height & width size
 4. Compress MB size (making it a little more pixelated)

How to test my video camera on Skype for Business??

My video failed on an interview last week using Skype for Business, where I had just installed Skype for Business Desktop.

I have another interview Monday and need to test it and be able to fix it.

How can I find if it's working??

I do not want to clic the link for the gut I will meet on Monday morning until Monday morning.

My Skype Video (Mac) is not working and I have an interview at 4PM EST today!

I see the option FaceTime HD and the second camera I plugged in ONLY after seeing the built-in camera was not recognized.

Using two microphones with Audacity (Mac High Sierra)

I have two microphones working as inputs with Audacity, via this box:

But, Audacity creates a single track with Left and Right sub-channels for a single channel, while I need each to have each microphone in its own channel.

Or, is there a way to convert a track with Left and Right to two distinct channels?

How to create a YouTube channel?

I created the GMail account but need to create a new channel for videos and podcasts

Audacity: How to mute all silent periods?

I have pauses between my speech, but sometimes I hear breathing and other small sounds which forces me to edit each one. Or, even a jet overhead which could not be heard as I spoke.

Is there a way to fix all these silent periods at once? Is there a feature (like Amplify) where I could reduce them all by about 10 Db?

I am having trouble using the Mitov Openwire VCL components TVLIPCamera.
I am writing a Windows 32 C++ application using Embarcadero XE10.2 to stream video from an IP camera.
I have a single for Form1 with a TVLIPCamera and VLImageDisplay component, the output pin of the TVLIPCamera component is connected to theinput pin of the
VLImageDisplay. I have set the URL property of the camera component to http://username:password@
the code compiles and runs but there is no video displayed. Mitov advertises the TVLIPCamera component as suitable for use with a "generic IP" camera although the term "generic" is not defined.

I can test the camera with an web browser using the following URL Which then prompts me for a user name and password,
after entering both, live streaming of video from the camera is displayed in the browser.
 I have monitored the network traffic to the camera with Wireshark and when the RAD C++ builder application runs, a TCP connection is made with the camera and Wireshark shows 9 TCP packet exchanges but then communication stops.
Any suggestions as to what the URL should be or otherwise what the problem might be would be greatly appreciated ?

The IP camera is a SANNCE Security Cameras Wifi 1080P which is manufactured by ANNKE
Getting a feeling for podcasting

I am about to launch my own podcast, but have little experience with podcasting.

Does a mobile user need a podcasting app? If so, what are the popular one for the iPhone?

I assume I could download it and see how various podcasts are displayed and accessed within the app. This would be very educational for me.

Virtual meetings with multiple participants. 2 or three extra screens facing me so I can see the participants.  Greenscreen behind me.

On top of the monitors is my camera.

I often forget to look in the camera when I'm speaking, or replying to a question.

Need a way to jury-rig a little red light on the camera.  Something to remind me to "Look here." when talking.

Any creative ideas?  Where can I find a bright red, but small single bulb light that I could stick on top of my webcam:

And, how could I get it to stick on there?


I'm looking for an iPhone X rear car backup Bluetooth camera backup system where I can install a camera on my rear car bumper (that gets power from my car) that then transmits to my iPhone X so that I can see behind me while I am backing up in my car.

What are some good Bluetooth cameras that do this?
Can YouTube force a user registration before a viewing?

I have a 15 minute training session video that I will offer for free, and will use Facebook to advertise it. But I only hope to show it to people who have registered.

I created this video to help build my opt-in list, so after they register (name and email) I send the URL for the video.

I expect to need to hide the video as Unlisted, but wonder if YouTube can only show a video to users who reveal themselves tome in the form of a name and email address?

I'd like to purchase a Video camera (GoPro or similar) that is easy to wear either on a cap or chest, but there is so much available when doing a google search that it's difficult to decide what's good and what's not.

Does anyone have any experience with this and can recommend a unit from personal experience?

Ideally, the unit I'm looking for wouldn't be too obtrusive and quick to put on when needed.
