The Importance of UPS Systems

What is a UPS?

Uninterruptible Power Supplies (UPS) provide battery powered backups to critical systems in the event of a loss to the building’s power.

Why using UPS is critical

  • Data Integrity
    Systems that suddenly lose power leave data “in-flight” vulnerable to loss or corruption. This includes data currently held in memory, not-yet recorded to non-volatile storage such as hard drives and SSDs, as well as data being processed. Despite software functions designed to protect against corrupted or lost data, sudden losses of power can still lead to such issues.
  • Protect Hardware
    Frequent power drops and power loss can cause higher wear and tear on electronic components, particularly those with moving parts such as hard drives which utilize spinning platters and moving read/write heads. UPS systems aid delivering clean, stable power to your devices extending their usable lifespan.
  • Prevent Downtime
    Backup power keeps the systems powered by UPS available in the event of a loss or dip in power.
  • Event Response
    UPS systems give users time to gracefully shut-down systems in the event of a power disruption.
  • Regulatory Compliance
    Depending on the industry, local, state, or federal laws may dictate required system uptime and system accessibility.
  • Power Surges
    In addition to providing backup power, many UPS systems provide additional protection against power surges caused by fluctuations in mains voltage or lightning strikes.

The points listed above affect not just exacqVision systems, but can affect any computer system or modern electronic device. Consider placing all mission critical systems on UPS.

NOTE: Exacq is not responsible for data loss, data corruption, or hardware failure due to sudden power loss on systems that are not gracefully shutdown.

Intelligent UPS Systems

Exacq strongly encourages the utilization of intelligent UPS systems. A UPS can only provide power for a rated amount of time. In the event of an extended power loss that could exceed this time period the UPS will run out of power, which can still lead your devices to experiencing an unexpected sudden loss of power. This is an indispensable feature for systems without someone monitoring them at all times to perform a graceful shutdown.

Today’s advanced UPS systems provide USB or networked communication solutions capable of communicating with the machines they are protecting. When the UPS reaches a low level of remaining power it is able to gracefully shut down protected systems to prevent an immediate power loss, safeguarding your systems and data.

  • APC offers PowerChute for Windows systems
  • Tripp-Lite provides PowerAlert software for Windows systems
  • CyberPower provides PowerPanel software for Windows and Ubuntu/Debian
  • Network UPS Tools is an open source tool providing Ubuntu Linux support for a wide variety of brands/models of UPS systems.

Sizing & Run Time

Refer to the datasheets provided at Exacq.com for your product’s power draw.

Most UPS manufacturers provide tools to help you find an appropriately sized UPS. When in doubt, consult electrical professionals.

Samsung PNM-C34404RQPZ Connection Issues

Description 

There have been several reports of connection issues with the Samsung PNM-C34404RQPZ. Reports of the units rebooting upon connecting it to the client and which plugin to utilize.


Product 

Exacq Server 24.03.7.0
Camera Info: Samsung PNM-C34404RQPZ
FW used: 23.01.04_20240417_R650

https://www.exacq.com/integration/ipcams/#getCameraRecord=901b747e-fcbf-5464-7543-5aeb7ae3afe8~nstep_id=step-3

Steps to Reproduce 

In the Client go to Add IP Cameras under the configuration. Add the first set of fixed camera’s as you would normally do for any camera.
Add the PTZ camera using the method seen below with the override.

Expected Results 

Camera should connect and work as designed.

Actual Results 

Some reports experience the camera rebooting during connection due to the none use of the power supply that is shipped with the unit. The Power supply must be used.

When connecting the camera as Hanwha or Samsung Plugin on older FW 23.01.03_20240119_R528 will connect but it was reported that motion was not working.

Solution

Update Exacq Server to 24.03.7.0 or above.
Use FirmWare 23.01.04_20240417_R650.
Add PTZ sensor manually using ipaddress#bank=2
Add the camera as Hanwha or Samsung device type.
Make sure the power adapter is of correct specification for proper functioning of the camera. Refer to the camera data sheet.


NOTE:
We have noticed Hanwha has started changing the gov size down to the framerate when users lower the framerate, but not the other way around.

If a user attempts to change a setting while the HTTPS connection is still being attempted, the camera has trouble sending data.

To check this, Log Into the camera web page and verify the GOV size is set to frame rate or higher. Out of the box they are set to 2x framerate. For example- 30fps 60GOV.

Missing Streams on Under Powered Multi-Sensor Cameras or Multi-View Devices

Description 

Loss of video streams have been observed on multi-sensor cameras and multi-view devices because of the camera or device being under powered.

Product 

  • AXIS FA54 Main Unit

Expected Results 

All video streams should connect and stream video

Actual Results 

3rd and 4th streams would occasionally disconnect and stop streaming

Solution

Follow the device manufacturer’s power recommendations and consider adding items such as a Midspan Power Injector when dealing with extreme distances.

How to Test an ATX Power Supply

Although there are portable power supply testers on the market that are inexpensive, it often becomes necessary to test whether a power supply is good or bad with only a multi-meter handy. The following steps detail how to perform this.

<br>

WARNING: When working with electricity always follow proper safety procedures. Remove jewelry from your hands. Do not attempt to open enclosures labeled “Non-Serviceable” or with warnings of electric shock. Do not touch capacitors which may still be holding an electric charge.

<br>

  1. Power down the system and remove the power cable(s) from the device.
  2. Open the server case and unplug the power connectors inside.
    • Follow the large bundle of wires from the power supply to the motherboard. You will find a large, plastic connector. This is typically white but may also be black.
    • Press the release down on one side of the connector and pull up to remove it.
    • A smaller bundle will connect to a 4 or 8-pin connector elsewhere on the motherboard. Disconnect these as well.
    • It is not necessary to remove the entire power supply from the chassis; just pull the connectors to a place you can easily access them.
  3. Examine the pinout diagrams. While some machines may have a 20-pin connector, others will have a 24-pin connector. With the pins facing you and the release clip towards the right the top-left pin will be pin number 1 and follow down the left side before beginning again at the top of the next column.
  4. You will need a short piece of wire to use as a jumper for the next step. If you have a 20-pin connector, insert the ends of the wire into pins 13 and 14 to short out this connection. If you have a 24-pin connector, insert the wire into pins 15 and 16
    • 20-pin -->  13 to 14
    • 24-pin -->  15 to 16
  5. Plug in the power supply. If it has no power switch you should hear the fan come on. If it does have a power switch, turn the unit on.
  6. If you have an Auto-Ranging multi-meter you can just set it to DC Voltage. If you have a traditional multi-meter, set the dial to the 10-Volt setting.
  7. Place the black (-) probe from your multi-meter on any of the pins labeled Ground (GND). Place the red (+) probe on the first pin and work your way around to each pin.
    • Make a note of the voltage reach from each pin. Click here for a printable worksheet to record these readings.
  8. Compare the values from your meter readings to the value that should be supplied.

Note:  These will almost never be exactly 3.3, 5.0 or 12.0 volts. Your actual meter readings should fall between the minimum and maximum voltage tolerances.

<br>

If your readings are above or below the allowable tolerances, noted on the worksheet, for that pin the power supply should be replaced.
