Which UPS would be best for my CCTV system?

If you’d like to read about why we suggest you need a UPS for your CCTV system click here, if you’ve come from that article and you’d like to know which UPS system would be best for your CCTV system, we’ve got you… keep reading!!

We’re going to skip through all the technical lingo and get right down to the run times each UPS will provide your CCTV system.

 

We’ve made it easy for you by assuming the amount of camera’s, starting with the most common household setup, 4:

*All calculations are estimations only

*Calculations are based on standard cameras (10watts each) and NVR with 3T storage and a modem  (40watts).

*PTZ, temperature and Bullet or turret dome cameras have a higher load.

 

The Eco-range is our entry level product and could provide a long enough run time if a burglar were to turn the power off before attempting a break in.

If you’d like longer run times, we have a range designed for security cameras to achieve run times for up to 36 hours, you can read about our CamSecure range here.

For any other run times please visit or calculator or contact us and we will a happy to help.

 

 

What are the benefits of using an external manual Bypass on UPS installations?

Starting with the basics, what is an external manual Bypass?

 

An interlocking manual bypass is used to retain power to critical equipment during UPS downtime seamlessly.

In layman’s terms “Bypass” is to go around, in the context of a manual bypass used on UPS systems, the bypass allows the power to go around and isolate the UPS, which may be necessary in event of UPS downtime.

Below is a basic image demonstrating the use of an interlocking external manual bypass (if you’re require more technical info, please contact us)

UPS Bypass demonstration

In image 1 we see the UPS operating normally, image 2 demonstrates how the equipment would operate with the UPS in bypass, using an external Bypass.

 

What about the Bypass that is included with the UPS?

 

At PSS all of our online UPS come with an internal bypass :

  1. The bypass is internal
  2. The bypass is automatic

Australian standards state, for safety reasons, all manual bypasses need to be external to the UPS to isolate for service purposes.

Below are images showing the internal bypass.

  1. Position of the internal bypass
  2. The mimic clearly indicates if the UPS is Online or in bypass

 

 

 

 

 

 

 

 

 

 

So, what are the benefit of an external manual bypass over the internal bypass included with the UPS?

 

In Essence, not having an external manual bypass would be for the critical equipment to be switched of in the event of UPS downtime.

Corporations trust UPS systems on their most critical equipment, this is where the Interlocking external manual bypass allows seamless maintenance and repair on the UPS without any interruption to the critical equipment.

UPS Topology – Line interactive vs Online double conversion

There are two main UPS topologies, line interactive and online double conversion. We are going to explain these and assist you to select which one would be best for your application.

This information is broken down into two parts; the layman definition, written by myself (I have a marketing and sales, non-technical background) and a technical definition, which we will be explained by our technical manager.

Layman definition

Line-interactive, the load is always running off the mains power, when the power is cut there is a short change-over time to the batteries (approx. 6ms) Line-interactive the power always go through and AVR and Surge protection before the load, thus the power is still being “cleaned”.

Online, the load is always running off the batteries, so we always have a controlled frequency (50Hz) and AC output (230V AC). There is no change over time with online for it is already on the batteries.

Overall, short change over does not affect most equipment (CCTV, basic computer equipment) , however online UPS is preferred for more expensive and sensitive equipment like servers and medical scanners.

Below is a diagram to demonstrate the difference between how a line interactive UPS “cleans the power” vs and online UPS. Please note if you are after a more technical diagram we do have this below.

comical description of line interactive vs online topology

Technical definition

Line-Interactive, during normal operation the mains supply is fed via an automatic voltage regulator (AVR) to feed the load. The AVR regulates the mains supply voltage, boosting if low or bucking if high. The mains supply is used to charge the batteries. When the AC goes out of the specified range, the load is switched to the inverter that draws its power from the batteries.

Online double conversion, converts the power twice, so during normal operation the mains supply is converted from AC to DC, the DC is then converted to AC that feeds the load. When the mains supply goes out of a specified range, there is no switching, and the UPS simply draws its power from the batteries.

Topology Comparison

Line Interactive Online Double Conversion
Normal Operation AVR supplies Load Inverter supplies load
Total Cost of Ownership Lower initial cost & Lower operating cost Higher initial cost                  & Higher operating cost                          (Energy & Heat generation)
Energy Efficiency during Normal Operation 96% – 98% 85% – 95%
Response to unstable or highly distorted mains supply Extreme voltage distortion can require frequent battery usage Accepts extreme voltage distortion without going to battery
Output Frequency regulation Output frequency varies within a range Output fixed to a configurable frequency

Why should you mount your equipment vertically in a data rack?

When selecting a data rack, once you know what size you need in terms of depth and RU, you have the option to mount your equipment horizontally or vertically.

Redback Racks have designed a series of specialty racks where you are able to mount your equipment vertically.

 

 

What are the advantages of mounting your equipment vertically?

Mounting your equipment vertically creates a smaller footprint, allowing the rack to fit into smaller more compact spaces.

Other features of our enclosed vertical racks VM.6904 and VM.6606 include:

  • Solid door and secure key –providing greater security
  • Cable entry (rear and top)
  • Earth studs
  • Cage nuts
  • Space to mount fans for ventilation
  • Holds up to 40kg
