www.mobotix.com


Suitable hard drives

• Always select high quality
hard drives
- Server/Enterprise/CCTV

• Consumer hard drives are
not designed for 24/7 use

• SSD drives: read reviews
www.mobotix.com


Suitable MicroSD

• Check class rating
• Be prepared for some failures
• USB speeds are slower
Class Speed x Rating

2 MB/s 13x

4 MB/s 26x

6 MB/s 40x

10 MB/s 66x

Operating systems for servers

• Choosing an operating system
- What knowledge is in-house?
- Customer SOE requirements?
- Are your chosen parts supported?
• Things to remember
- Servers often require licenses
- Must be managed properly
www.mobotix.com


Failure pre-warning

• Hard drives will fail!
- S.M.A.R.T. monitoring
- Built in notiﬁcation of
impending failure
• Storage Failure Detection
- Built in to camera
- Post-failure only
www.mobotix.com


Warranty can save your backside

• Standard consumer product warranty
- 1 year, return to base
- No footage recovery options
• Enterprise warranties
- Multi-year, on-site or direct shipped parts
- No risk to footage security
- Footage not lost if recoverable

Appropriate hardware choices

Your customer wants you to dig a 3km trench
www.mobotix.com


Appropriate hardware choices

Capable of 2 cameras Capable of 30 cameras
www.mobotix.com


Single camera on remote 3G connection.
7 days event based recording (~10 events per day).
Solar power, power usage must be minimal.
www.mobotix.com

==> Internal SD Card or USB Device

Many cameras on a node-based WiFi network
30 days recording, mixture of event + continuous
Wireless traﬃc must be minimal to avoid lost footage
www.mobotix.com

==> NAS for each node

120 cameras, wired on the corporate LAN
30 days recording, mixture of event + continuous
Storage device must meet SOE requirements
www.mobotix.com

==> Server or NAS depending on speciﬁcs

I’ve selected my
hardware, now what?

Allocating the available space

• RAID reduces space - check actual remaining
• NEVER allocate every last megabyte!
• Allow approx. 10% space as free

Security, it’s important!
www.mobotix.com


Security, it’s important!

• Only give the rights absolutely required

• Always create at least 2 users
- MxCam | Read/Write
- MxCC | Read Only

• Separate device users from admin
www.mobotix.com


UPS backup, even in Australia
www.mobotix.com


How do I test
storage devices?
www.mobotix.com


Stress testing storage devices

• 2 tests - Continuous & Event based
- All tests performed at QXGA, full frame rate

• Run for 2-3 months at full load

• When drives are 100% full:
- MxCC synchronous playback
- Search and export of footage
www.mobotix.com


Example: incorrectly speciﬁed storage

... Network ...
www.mobotix.com


Optimising MxCC
Performance
www.mobotix.com


Optimise MxCC access to recordings

• Set MxCC access direct to
storage medium

• User “via Camera” only when
absolutely necessary
- SD card is via
camera only
www.mobotix.com
