Camera Setup: U-Filter

In this tutorial we will examine how to setup a camera in order to work with U-Filter.

NOTE: U-Filter has an implementation dedicated for Milestone XProtect. For that version, you can skip this article entirely.

Before you start

Before you begin configuring your cameras, please make sure that you have all of the following available; note that these are data provided by the U-Filter web interface. For more information, read our guide on setting U-Filter up.

SMTP settings for e-mail sending:

Sender Address: Not used, any value is acceptable.

SMTP Server: <youraccount>.ufilter.ultinous.com

SMTP Port (depending on encryption): 465 ( if SSL/TLS), 25 or 587 (if STARTTLS or No Encryption)

Authentication: Yes

User Name: <username> or <username>@ufilter.ultinous.com

Password: <password>

Receiver's Address: <cameraemail>@<youraccount>.ufilter.ultinous.com

• NOTE: This email address is different for each camera.

Setup Steps

Common camera settings

U-Filter analyses video snapshots. The maximum resolution is 1920 x 1080 pixels: larger resolution images will be scaled to Full HD. The minimum detectable object size is 32 px (vertical) on a Full HD image.

Special settings for thermal cameras

Regarding the minimum detectable object size, it is the thermal sensor that matters, not the upscaled video image.

For U-Filter, it is recommended to use "white on black" color scheme for better accuracy.

Triggering event

Every image processed by U-Filter has a camera as their source. Image taking is triggered by events - such as a built-in intrusion, person, vehicle detection or a simple motion detection. Such camera-generated events detect all incidents while also produce high false alarm rates - which are going to get filtered by U-Filter.

NOTE: It is very important that each incident should trigger an event on your camera. U-Filter removes the false events and retrieves the real ones. However, the performance of the solution is affected by the number of false alarms - therefore the more advanced the triggering event is, the less load U-Filter will have. This means that built-in object detection (with high sensitivity) is preferred over motion detection.

Sending a snapshot to U-Filter

Once an event is triggered, a snapshot image is sent to U-Filter. Multiple image sending is allowed, in that case all images will be analysed.

Email (SMTP Settings)

The image is sent via e-mail. The required e-mail parameters need to be ready before proceeding.

Setup Examples

Axis

This configuration was tested on the following cameras:

• AXIS Q6315-LE PTZ Network Camera

• AXIS Q1941-E Thermal Network Camera

In order to send images to U-Filter, the following steps are required:

• Create an mjpeg stream profile for image extraction.
• Setup a motion detector.
• Configure email settings.
• Create a Rule which extracts an image upon motion detection and sends an email to U-Filter.

Create an mjpeg stream profile

1. In the bottom menu select the Stream tab.
2. Click the Stream Profiles button

3. In the pop-up click the Create new label.

4. Give a name to the new stream profile.
5. Set the codec to MJPEG.
6. The recommended resolution is 1920 x 1080.
7. Set the Frame rate (fps) to at least 1.
8. Set the Compression level to a low value (5-30).
9. Click the Create button to finalise the stream profile.

Setup motion guard

1. In the bottom menu select the Apps tab.

2. Select AXIS Motion Guard.

   Note: In this example, Motion Guard is used, but any other triggering event is appropriate which detects all real incidents at a cost of high false alarm rate. False alarm rate will be lowered by U-Filter.

3. Define the Include area and Exclude Area.
4. (optional) Define Filters to avoid unnecessary overload of U-Filter.

Email settings

1. In the bottom menu select the System tab.
2. Select Events.

3. Under the Device events select Recipients. Let's add the e-mail settings.

   Note: This is the step where the SMTP settings you received for U-Filter can be configured.

4. Give a name to the setting.

5. Type: Email.

6. Send email to: type the Receiver's address here. (e.g. cam1@bpt.ufilter.ultinous.com).

   You can use only one email address for a single camera. Different cameras need different e-mail addresses.

7. Send email from: not used, any email address is acceptable.

8. Username: type the User Name here.

9. Password: type the U-Filter Password.

10. E-mail Server (SMTP): type the U-Filter SMTP Server address here.

11. Port: 25

12. Encryption: None

13. You can test these settings with the Test button. Only the server connection gets checked, no images will be sent to U-Filter. If the test is successful, you can be sure that the email settings are set properly.

14. Click the Save button to save these settings.

    

Creating a Rule

1. In the bottom menu, select the System tab.

2. Select Events.

3. Under Device events, select Rules.

   Note: This is where you will convert your settings into a Rule for U-Filter.

4. Name your Rule.

5. Set the Wait between actions for a low value, e.g. 2-3 seconds.

   Note: This value acts as a cooldown, therefore setting it to a value too high may result in missing some detections.

6. Condition: Select the profile created at the top of the window (Motion Guard: Profile 1 in our example).

7. Use this condition as a trigger: yes ✔️

8. Select Send images to email as the Action.

9. Select the previously created MJPEG stream profile as the Stream profile.

10. Set Maximum images and Send up to this many images to email to ensure that there will be at least 1 image about the incident. In this example we set it to one. These values ensure that one image gets sent per e-mail.

    Note: Sending too many images puts unnecessary load on U-Filter servers making your system performance unoptimal.

11. Type a Subject and Message to your liking, and leave the rest of the settings as shown on the image above.

Bosch

This configuration was tested on a Bosch DINION IP 500 HD camera.

Alarm Settings

1. In the upper menubar, select Configuration.

2. In the left sidebar, under Alarm, open VCA .

3. Setup the triggering analysis type here, such as motion.

E-mail settings

1. In the upper menubar, select Configuration.

2. In the left sidebar, under Alarm, open Alarm E-Mail.

3. Set Send alarm e-mail to on.

4. Fill in the SMTP settings according to your server's configuration.

5. Format: choose Standard (with JPEG).

   Note: U-Filter requires this format.

6. Image Size: Set the required resolution here.

7. Attach JPEG from camera: yes ✔️

8. VCA Overlays: Make sure it is turned off.

   Enabling this option would draw additional bounding boxes over the images, which would affect the accuracy of U-Filter.

9. Destination address: Type the e-mail address you received for this camera only. Make sure that the e-mail address is not used elsewhere.

10. You may test your configuration by pressing the Send Now button. Only the server connection gets checked, no images will be sent to U-Filter. If the test is successful, you can be sure that the email settings are set properly.

Hikvision

This configuration was tested on a Hikvision DS-2CD2F42FWD-IWS camera.

E-mail settings
