he subject that has become commonplace in the world of CCTV is about the need to have cloud recording in your system.
If you still do not know what the cloud is, read this article before continuing.
Cloud recording is the use of memory and the storage capacities of shared and interconnected computers and services over the Internet following the emergence of grid computing.
Little is noted, but the cloud recording has been increasingly present in our lives.
A service designed to help people who start a hiring of electronic surveillance and who have cameras installed in their homes or companies is the CCTV installed in the cloud.
This system seems to bring advantages to those people who want to keep up with remote monitoring since the cloud will act as a portable HD.
Enabling monitoring of wherever the owner is.
This remote monitoring will greatly depend on the user’s need to have or not the remote monitoring that includes the use of the cloud.
But before that we will talk a little about the advantages and disadvantages of using this system and the consequences related to the use of this technology.
How Cloud Recording Works
As it was said at the beginning of this article, this system seems to take advantages for those people who want to follow the monitoring from a distance.
Since the cloud will act as a portable HD, allowing the monitoring of wherever the owner is.
Thus, videos created by the camera CCTV, Encoder, DVR or NVR are released to a server on the Internet where they are stored.
This allows you to access the recorded images, and you can watch them as many times as you want, to prevent a possible problem, such as theft of the recording camera itself.
The cloud system is responsible for receiving the second image emitted by your camera, since the first image is kept in the local storage.
It is always good to have the recording recorded in more than one place ( DVR, NVR or IP camera).
Cloud monitoring can be very important to your business because it protects the images received by the cameras beyond your remote access from any region!
Images are stored in the cloud. Then, if there is any theft or burning of the safety kit, all information will remain safely protected.
Hiring Cloud Record Service
We find in the market a great variety of services.
Some companies offer their equipment such as IP cameras and DVRs that enable cloud recording at no extra charge over a period of time.
In case the client wants to have a good recording period, it will be necessary to pay an extra fee (a completely normal behavior when we demand excellence).
This is also about storage capacity in the Cloud (style Google Drive ).
But it’s not just Google Drive that provides this kind of service.
You can search for companies such as:
- ADrive Services;
- Amazon Cloud Drive;
- Google Drive;
Just get in touch with any of them to carry out the scheduling and get all your questions about the product.
IP And CCTV Cameras Installed In Cloud
Few people know this, but it is possible to attach a memory card to a camera to make recordings and even make copies of the images to send them to a recording server in the Cloud.
Of course, the space of a simple memory card does not compare to the space of a hard disk (HD) and this will greatly reduce the recording time.
If we use a memory card the recording time will not exceed 7 days.
A bit different from the memory card, the cloud recording server, also provides a limited time of operation.
But this will depend exclusively on the contract required by the customer, such contract offer 7, 15, 30 days or more (this will depend on the customer’s need).
If you intend to use the memory card to make the recordings, be careful!
Make sure the memory card has compatible recording speed, as well as being of a good brand, otherwise the recording will not be performed to perfection.
DVR With Cloud Recording
When using the DVR, local recording can be viewed by the DVR itself and at the same time the DVR provides a copy of the video to the server where the recording is located.
The DVR often stores more time in the local recording because it has an internal hard disk ( HD ) that allows it a greater capacity of recording compared to the use of memory.
While local video recording is done with high quality video, the quality of recorded images in Cloud will be somewhat lower.
This happens due to internet traffic, so you need to make sure that your bandwidth usage is in accordance with the size of the internet link you have contracted.
The Need For Bandwidth For Cloud Recording
The amount of bandwidth required to perform the service will depend a lot on the CCTV projectyou want, the quality and quantity of cameras in operation.
The use of the band from 256kbps per camera to perform the recording in the cloud is good, since it does not matter if the camera is of an IP model connected to the router or if it is a camera DVR device connected.
In any circumstance it is possible to configure the devices to regulate the use of band.
Supposing you have a DVR with 4 cameras. Considering that 256kbps for each camera you will have the total of 1024 kbps, that is, 1Mbps.
With high-quality local recording (DVR) and poor quality cloud recording, you will not be able to stream images with a high resolution and high frame rate at 256kbps.
You will need a much higher rate of kbps.
Is It Possible To Upload High Resolution Videos For Cloud Recording?
Sending high resolution video through the cloud is completely possible, but of course this will depend on the features and equipment at hand.
As said before, performing a service with excellence is always possible, however, the cost ends up being greater.
The cloud recording service works with space, so the higher your image quality and storage space, the higher the cost to be paid.
Example: DVR WITH 16 CAMERAS LOCAL AND REMOTE RECORDING
- 01 DVR with input for HD-TVI technology cameras
- 16 HD-TVI cameras with 1080 resolution (2mp)
- 01 internet link with 20 mbps upload
- 01 contract for a company to record in the cloud
To send the images for recording in the cloud, we will have the available 1.25 Mbps for each camera (internet link 20mbps / 16 cameras).
Assuming we are going to record the 16 cameras in high quality on the DVR device with the base resolution of 1080 and with a frame rate of 15FPS, with the common spacing that uses the H.264 smart CODEC and broadcast over the internet with resolution and frame rate.
The cameras, once connected directly to the DVR, will need a good hard disk capacity to store the local videos.
If you have questions about the DVR’s storage capacity, check out this article here.
As a result, local recording will not be a problem as it will not affect bandwidth usage.
To transmit good video quality, an average of about 2.5 mbps per camera will be required, otherwise image quality will be compromised.
The example gives us about 1.25 mbps per camera so we will not be able to upload videos with the same quality we are recording (1080 / 30fps).
On this basis, the quality of video streamed for recording in the cloud will be reduced, in which case we will have a resolution of 720p with a rate of approximately 10fps.
Value Of A Cloud Recording Project
To know the value of your CCTV project with cloud recording, you need to have an idea of everything:
- Value of the material (DVR, cameras and accessories);
- Installation by a technician;
- Bandwidth required
- Cloud storage service.
Then knowing for sure the amount to be paid is very difficult since each client has their preference.
Compared to the example quoted above, the amount to be paid will be R $ 1,318.30 per monthfor the recording of 16 cameras with a resolution of 720p and a frame rate of 10fps.
So this price can several many times depending on the service you will choose to carry out your project and in case you want to record in FULL HD1080p.
The price quoted in this example (R $ 1,318.30) was based on a table of one of the product’s suppliers, so do not be alarmed by it, as it can vary to more or less.
Conclusion: CCTV Installed In Cloud
The use of cloud-based cftv can be very helpful since it allows the client remote monitoring and emergency backup.
Despite its rather high value, I believe it will not bother you, because when we talk about our safety, we always demand the best.
