Night Color, color images in low light

One of the most complex scenarios in video surveillance is that of situations of little to no lighting.

 

night color

At Visiotech we have cameras that incorporate Safire's Night Color technology, with the ability to provide an efficient solution to surveillance situations in which lighting is a problem, guaranteeing and improving safety as much as possible.

These Night Color cameras are capable of displaying and capturing a vivid color image in low light situations. Our range of Safire cameras have been evolving, introducing new technologies, with better features and all kinds of innovative functions based on technologies intended exclusively for video surveillance.

 

Our Safire Night Color cameras, to capture images in low light conditions and display them in as much detail as possible, have two very specific technological advances in hardware.

One of them is the advanced lens they contain, with an aperture capacity of up to F1.0, which allows more light to enter the lens with the intention of presenting more brightness in the images, lenses that are very different from conventional lenses. The other important parameter that Night Color cameras present is that of a high-performance sensor.

 

The Safire Night Color camera lenses are made up of a wide-band anti-reflective coating and extra low dispersion optical glass that make it easy to reproduce the image clearly and with the appropriate color saturation. Also, due to their filter to reduce flares, they are able to regenerate the essential information of the part of the image that has been obstructed due to a flare.

safire night color

 

Due to their high-performance sensors, Night Color cameras are suitable for monitoring areas where lighting is very poor and high-resolution color images are required. This advanced sensor technology, presents an optimal light collection, promoting its use and application efficiently. With a lighting of 0.001 lux with an aperture of F1.0, Night Color cameras reproduce an image clearly and with appropriate color saturation despite unfavorable lighting conditions.

 

On the other hand, the Safire Night Color cameras have a complementary white light, so that when there is no fenced-in light source it can still guarantee a color image. This type of light provides a soft, warm and adjustable illumination, avoiding any glare in the scene of the image on the illuminated object.

 

For complex installations, it is important to differentiate Night Color technology from Safire's Ultra Low Light technology.

The Ultra Low Light solution of our Safire cameras is suitable for use in applications where conventional infrared lighting is insufficient, and more detail needs to be obtained from those areas where infrared illumination without the need to obtain a color image for analysis. However, Safire's Night Color technology is intended for applications where a color image is required or needed, for example in video analytics.

 

Night Color cameras are suitable for a multitude of scenarios or installations where lighting is poor, such as poorly lit public places, industrial areas guaranteeing night security, traffic intersections where ambient lighting is very poor. In general, they are intended for applications where it is important to obtain color image information at all times.

 

Within our Safire camera ranges, Night Color cameras are found within our ULTRA product range.gama de cámaras safire night color

Ehome protocol configuration on SAFIRE presence and terminals.

The Ehome protocol is available in some Safire products and allows us to have connected to the Safire Control Center program a presence or access terminal that is not running on the same local network where we have the Safire Control Center software installed, by opening the service port.

The following shows how the Ehome protocol can be configured on Safire terminals from the Safire Control Center application:

  • First, we must connect the Safire terminal to the local network in order to activate the product and register it on the app.

 

  • Once the terminal is registered in the app, go to Access Control – Advanced Function – More parameters
  • Once the corresponding terminal has been selected in the Network section, we must configure the Ehome protocol:

mceclip0.png

Below we indicate what each field within the network parameter of the terminal is used for:

-Group Center: in this parameter, you must choose the group of devices to which the device will belong

-Address Type: choose the type of server address, which in this case can be IP or Domain

-IP Address: specify the public IP address or domain name of the server where the Safire Control Center software is installed.

-Port: the port to be used by this protocol for communication must be specified. By default it is always port 7660, if you want to change it to another port you must also specify it in the Safire Control Center program, as shown in the following image:

mceclip1.png

-Protocol Type: specify the type of protocol, which in this case must always be Ehome.

-Ehome Version: you must specify the protocol version, in this case, we recommend the Ehome5.0 version, as this version allows you to establish connection credentials for a more secure connection.

 

-EhomeKey: you must specify the connection password (these fields will be necessary when trying to register the device in the application using the Ehome protocol)

-Account: the name of the Ehome account must be specified (these fields will be necessary when trying to register the device in the software using the Ehome protocol)

  • Once the above fields have been configured we must also modify the Upload Mode as follows:

mceclip2.png

  • Once this configuration is done we can connect the terminal outside the local network and we could already register the terminal in the program but this time using the Ehome protocol:

mceclip3.png

  • Once everything is configured we have to wait more or less 1 minute for the communications to be established and in the Devices section the device should already appear as “ONLINE”.

For the Ehome protocol to work correctly, you must allow communication on port 7660 (both internal and external communication) by opening the port on the network where the Safire Control Center software is installed.

Coaxial audio or RCA input on Safire SF-XVRxxxx(A)S recorders

To establish which is the type of audio is going to use in a Safire recorder that has the possibility of using physical audio inputs by RCA and audio over Coaxial HDTVI, via the monitor use the mouse to select the section:

Change Technology in SF-SD6025IW-F4N1

To change the video technology of the camera we must alter the positions of switches 8 and 9.

HDCVI: 8 OFF 9 ON HDTVI: 8 OFF 9 OFF

CVBS: 8 ON 9 ON

AHD: 8 ON 9 OFF

A reboot is required to enable the changes.

mceclip0.png

Pins 1 to 5 refer to the Hardware ID, and pins 8 and 9 are used to establish the communication protocol.

PoC – PoC Transmission Distance

The transmission distance is related to the cable material and the power of the connected PoC camera.

mceclip0.png

– Better cable material (less resistance), larger transmission distance.

PoC – Disable PoC on a given channel of a Safire recorder

To disable a specific PoC channel, we recommend updating to the latest firmware available; to do so, consult the Visiotech website directly or contact our SAT.

To check the PoC channels, go to CAMERA MANAGEMENT / CAMERA / PoC INFORMATION

mceclip1.png

To do this, simply click on a specific channel and leave it on OFF status.

– You can click on the channels in PoC Channel to turn on/off the PoC power supply. Turn on the PoC power supply only when the Recorder is connected to Safire PoC cameras, otherwise please turn off the PoC power supply.

– You can see the type of cameras currently connected. The icon of the channel that is connected to an AT / AF camera will light up and display AT or AF accordingly.

Safire and Hikvision: unbinding a device from a P2P account

In order to disassociate a Safire device from the corresponding P2P account, without knowing the password of the aforementioned account, you can proceed as follows:

  • Download and install the SADP v3.0.1.8u software. You can download it from this link. IMPORTANT: it is possible to do it only with this version
  • Once the program has started, select the device in question using the appropriate box on the far left
  • Click on the ‘Unbind' button at the top right

 

 

  • In the window that appears, enter the username ‘admin', the password of the user in question and the verification code in the image on the right;

 

 

  • If everything went well, the software will return a confirmation message to us.

How to activate extra IP cameras on a SAFIRE XVR

The images in this example are taken from a recorder model SF-XVR6116S.

In this image we see that the 16 analog cameras of the model under consideration can be replaced, and that it only has 2 extra IP cameras according to basic specifications.

mceclip0.png

Now, by activating this option locally, with the screen and the mouse…

mceclip1.png

We'll get the rest of the extra cameras. In this case, six more. That is 8 in total plus those that could be replaced, for a total of potential IP cameras of 16+8=24 units.

mceclip2.png

This option is only available on recorders that support this extension.

For the most recent (versions 4.X, due to be released in the middle of 2020), the same option will be found in the System menu:

Requesting an mjpg image from a SAFIRE recorder or camera via HTTP or Snapshot

To capture a requested image from a url (snapshot):

 

The default http port is 80

 

  • http://<user>:<password>@<IP address of IPC>:<HTTP port>/Streaming/channels/1/picture
  • http://<user>:<password>@<IP address of IPC>:<HTTP port>/ISAPI/Streaming/channels/1/picture
  • http://<user>:<password>@<IP address of IPC>:<HTTP port>/ISAPI/Streaming/channels/101/picture?videoResolutionWidth=1920&videoResolutionHeight=1080

 

 

If you wish, you can remove the username and password) so that the browser prompts for credentials before returning the password.

 

Following examples:

– http://admin:password@192.168.1.64:80/Streaming/channels/1/picture

– http://admin:password@192.168.1.64:80/ISAPI/Streaming/channels/1/picture

Cloud recording with Safire: available services and suitable recorders

The services that historically support cloud recording for Safire equipment are as follows:

 

– Dropbox

– Onedrive

 

It is important to note that as of today (January 2020) GoogleDrive has temporarily disabled the service, pending further decisions on its industrial policy at international level.

 

With regard to the recorders that offer this possibility, it is a question of:

– those that end up in HEVC

– those that end up in AI

– the new SF-XVR with audio over coax (except in case of firmware errors)

RTSP SAFIRE

To view a video, the basic RTSP string we have to use is:

If the Port is 554 by default, there is no need to set it.

In the case of a camera, there is only one channel, so we will always put 1. But in the case of a recorder, we can indicate the channel from which we are interested in extracting the flow.

If we indicate the username and password in the string, it will not be necessary to enter these when the system asks:

If we also want to indicate the type of flow we want to use, we usually have up to 2 options in Safire. The first will be the main (higher quality) flow and the second will be the secondary (faster but lower quality) flow.

The flow is indicated just behind the channel ID by adding 01 for the main flow and 02 for the secondary flow.

Example to open opens channel 2 with the main stream:

&lt;font color=#38B0DE&gt;-=rtsp://admin:12345@172.18.219.239/Streaming/Channels/201=- Proudly Presents

To open channel 2 with the secondary stream

rtsp://admin:12345@172.18.219.239:554/Streaming/Channels/202

 

Remember that RTSP strings are usually played through web plugins or a program like VLC for pc/mac.

How to activate flash (red and blue) and siren on camera SF-T943CW-PIRS-2U4N1

False alarm filtering by coaxial PIR on this type of camera is configured from the Safire DVR's configuration menu.

Flash and siren deterrents are linkage actions that are programmed from the PIR filter detection tab.

 

Therefore, the PIR filter is first configured in the  section of the recorder.

When the event is triggered by the detection, the deterrent effect is activated.

The relay output is activated within the linkage action subsection of the motion detection.

 

Also remember that it all depends on the type of interface the recorder has; whether it is the old or the new GUI4.0, where actions can be configured separately, the appearing tabs might be slightly different.

 

Next we leave an image taken from one of our Safire trainings in which we display a summary of the configuration possibilities depending on the recorder's firmware:

 

Independent outputs on Safire video recorders

Search for Safire units with independent outputs:

http://visiotechsecurity.com/es/search?keyword=independientes%safire

On Safire equipment with independent outputs equipment, the selection menus from which to operate remain on only one of the screens, the one chosen as the main one (typically HDMI1).

However, you can switch the mouse control momentarily to the secondary one if you want to rearrange the channel layout directly (without doing it through the internal menus)

We provide a demo in our Safire CCTV course and specifically in the certification course at minute 1:34:34:

Recorders compatible with Safire analogue deterrent cameras with flash (red and blue) and siren

These cameras detect with their PIR sensor and send the alarm signals to the recorder through their coaxial cable.

The recorder has a section within the motion detection where the false alarm filter is configured. So the camera provides no deterrent function without a DVR.

The configuration on the DVR can be seen in the following video:

https://youtu.be/BYT4iTBynNo

 

The recorder models that support this function are all 4N1 recorders from Safire, Hikvision and Hiwatch, according to the specifications described below.

The deterrent action does not work with other brands.

 

COMPATIBLE RECORDERS:

  • Hikvision DS-7xxx-Kx series, starting with firmware 3.5.30
  • All Safire DVRs with H.265+, starting with firmware 3.5.30.
  • All new Safire XVRs are supported.

 

FEATURES

Firmware 3.x (greater than 3.5.30): Only allows the siren, flash and relay to be activated at the same time, when the PIR sensor performs the detection.

Firmware 4.x : The new user interface GUI4.0 (series 6 and 8) and E-GUI (series 3) already allows to select each action separately.

How to disable alarm or buzzer for lack of hard disk (HDD) in SAFIRE recorder

The deactivation of this option is mainly when you are going to work with the recorder, without using a hard disk. To avoid this acoustic signal, we must deactivate this option:

 

mceclip0.png

 

Sometimes it is also necessary to deactivate this option:

 

Important Note: It is very convenient to re-enable these options after installing a hard disk.

How to switch to default main stream for web viewing in SAFIRE

Choosing the default main stream is only fixed for 1ch or 4ch simultaneous view, from 9ch onwards the default secondary stream is chosen because it is understood that from it will have a lot of load for the system and that the size of the individual channel window will not appreciate the maximum resolution.

 

 

In 4ch recorders, if the zero channel is enabled, it loads by default a view that allows to show all 5 at the same time (the 3×3 view), in order to make this configuration you have to disable the zero channel.

 

 

In local (keyboard and monitor) the zero channel is disabled in the Live View section, when accessing by web browser the 4-channel view is loaded directly with the main stream selected.

I can't find the Web Platform Access menu for P2P on Safire recorders

Rarely accessing the web in English the P2P section exists, but is blank and clicking in the gap between the previous and subsequent sections is accessed.

If it still does not appear, if you have the opportunity to access it locally (monitor and mouse), this is the quickest way to check if the section exists in the network settings.

Battery symbol on X-Security 4N1 camera OSD

This symbol means that the voltage that the camera is receiving is not sufficient, either due to losses in the length of the cable or due to a defect in the power supply.

The image may be displayed, but when the consumption of the infrared LEDs increases, it may turn off or the screen may go black.

SAFIRE Rackmount Recorders

Generally, Safire 16CH recorders with space for 2 hard disks, allow to mount the special “SF-ENRACK” tabs, which adapt to a rack cabinet allowing the recorders to be rack mountable.

In the case of devices that, a priori, are not rackable and do not allow mounting tabs, the special trays for rack cabinets, of the “SHELF-” type, allow to place devices that are part of a rack cabinet.

SF-T943A-5P4N1 – Changing Technologies and Resolution

The SF-T943A-5P4N1 camera works in the 4 technologies TVI, AHD, CVI, CVBS.

 

In TVI works in 2Mpx, 4Mpx and 5Mpx.

AHD 5Mpx and 4Mpx.

CVI 4Mpx.

 

If the camera is in TVI or AHD in 5Mpx, you can not change the technology until you lower the resolution to 4Mpx.

Note: 

Be aware that you need to have a recorder that supports TVI and 5Mpx or you can use one of the Safire Testers: Link to the Safire tester – Safire CCTV Tester a must for every installer

Noise or image interference in analog cameras

When these interferences or chromatic aberrations can be seen in the image, they can be caused by several cases that only occur in analog cameras and not in IP cameras.

 

mceclip0.png 2022-03-10_10h59_14.gif

 

Possible causes:

  • Wiring close to power cables, reactances or large electro-magnetic sources.
  • Noise in the electrical network entering through the power supply to the equipment.
  • The use of shielded UTP cable, not carrying the shield to ground.
  • There are probably more reasons but less common.

 

Possible solutions:

  • Separate power supplies.
  • Use switched-mode power supplies, connected to ground.
  • Increase the voltage to 12,3V
  • Increase Amperage
  • Separate CCTV cabling from other electrical cables.
