School Hall Audio Control – Headend Upgrade. Simplicity Works Beautifully

Just wanted to show you a great result we have achieved for one of our clients. The Southern Cross Catholic College who we have done some audio visual works for previously had a problem recently where the Biamp Tesira headend had a meltdown. This was caused by a significant power surge. We were investigating the best approach to the replacement of the Biamp Tesira DSP – Digital Signal Processor. We found that the best option to avoid a significant programming and upfront equipment cost would be to install a Soundcraft Ui24R mixing console. The beauty of these consoles is their simplicity. They have plenty of functionality straight out of the box to run a significant production as a portable arrangement or in this case a control for the school hall.

The Soundcraft Ui24R can output its own wifi signal so tablet control is easy to set up and operate. No actual internet signal is needed to make it work. The user interface for the tablet has loads of presets in there for various sound installations and productions. For this situation all we have needed to set up some user access levels so that students and novices alike can control the system without having access to change tuning settings of the hall sound system and microphones. Quote a good result and a great example of the right product for the right application.

Simplicity works beautifully. Sometimes the outcome is simple on the surface but not so simple to deliver. Contact Voltec Services for great results in audio visual.

How can HD-SDI technology save you $$$ when upgrading your CCTV system

So here is the situation.

You have an existing analog CCTV system that has been working OK and you have had it since the Burdekin Dam was built. You have had some sort of incident that requires you to provide descent footage to identify a person or vehicle to police. The footage just doesn’t cut it because the old analog CCTV resolution comes out blurry once again. We won’t talk about the fact that most CCTV systems around are not maintained properly to ensure the best possible images for that camera are captured on an ongoing basis. Assuming the camera is in focus, we are talking resolution issues that just do not cut it when it comes to identifying persons.

This is all too common.

So you have considered and upgrade based on necessity because those existing cameras no matter how much you adjust or refocus them will not get the resolution that you are after.

This is a fair conclusion for the situation.

So you have no doubt heard about IP cameras, network cameras, digital CCTV. All the same thing. Just some different names. These types of cameras are commonplace in today’s market and are gaining a bigger slice of the market share all the time. So any discussion of upgrades would include a switch to this type of CCTV system at least as a possibility.

What I want to drill down to for this particular blog is the actual nuts and bolts of upgrading a system. So when we are comparing an old analog surveillance system to a new IP network surveillance system what is the most obvious difference for a system such as this? The answer is the cabling.

All of your existing analog cameras are joined to the DVR – recording device with coaxial cabling (the same as TV antenna cable) and twin to power the camera.

New IP network camera systems use a single data cable (also known as twisted pair). This is part of their popularity. Less cables to run and terminate. There are other functions available and also more scalability though we are not talking too deeply about IP systems right now.

Here is where we get to the point. What do you do if the camera locations are not accessible for replacement cabling? How much are you willing to pay for an installation of new cabling? Have you actually had any quotes for a replacement cabling infrastructure that would make you fall off your chair because the labour cost to replace all of that cabling is astounding?

This is where an upgrade to HD SDI cameras can really become a saviour.

Take a large portion of the labour content out because you do not have to pay for the cabling to be replaced then add the cost of the equipment which includes cameras and a HD capable recorder and complete the setup. The existing analog cameras will even work on a HD recorder if you want to upgrade a section at a time. Here are some photos to compare the two technologies working on the same piece of cable.

Here is a chart that shows the different resolutions in the market today. New cameras are always pushing this boundary. HD resolution of 1920 x 1080 can give you awesome results and this is the proof.

CCTV Code of Ethics

CCTV Code of Ethics

Below is the CCTV Code of Ethics from ASIAL (Australian Security Industry Association Limited) for your perusal.

1. CCTV is focused on providing an extra “set of eyes”, particularly where hazards or difficulties apply to continual personal monitoring. These difficulties may relate to access constraints, environmental constraints or cost constraints.

2. The primary objective of deployment of CCTV equipment should be to:

  • Act as a deterrent against criminal activity or unruly activities
  • Provide assurance, security and safety to people occupying the spaces covered
  • To maximise the deterrent value, and consistent with privacy requirements, camera usage should be notified in public areas

3. Staff should be informed of any use within their work areas.

4. CCTV systems should not normally be utilised purely for staff monitoring and surveillance.

5. No CCTV camera should be deployed within toilet and change room facilities.

6. All equipment being sold must be suitable for the application it is being applied to.

7. All sales staff should “clearly and in plain English” explain the strengths and weaknesses of each type of product or system. The explanation should cover applications, ethics and the equipment or environmental constraints.

8. CCTV sales staff should cover maintenance requirements and cleaning necessary for optimum performance of the system being offered.

9. The equipment installation should be covered by a minimum of 12 months parts and labour warranty.

10. At commissioning, clear and concise instructions must be provided on the operation of the system.

11. The use of CCTV cameras is to add value to the environment in which it is utilised. To this end, the net value of its use must outweigh the constraints or restrictions it imposes.

Security Licencing Queensland – In Focus

asial-member-logo

 

A security licence is a legal requirement for a business or a person who engages body guards, security officers, crowd control officers, private investigators and surveillance equipment installers who offer their services at a fee.

A security surveillance systems installer is a professional who is paid to install and maintain a set of security hardware and software. The security equipment that a business must be licenced to install are; Locks, safes and vaults, CCTV equipment, Electric fences, security alarms and bullet proof materials.

These security compliance certificates can either be issued to individuals within the organisation, the corporation itself or partners of the corporation. In Australia security licence is issued by the Queensland government.

There are no special qualification requirements put by the Queensland Government for security service providers. However, there are certain staff within the security firms which must have a set of qualifications before the firm can be licensed to offer the security services.

Security sector licensing in Australia is devolved. It is regulated and effected by either state police, department of consumer affairs or the department of fair trading. At Voltec Services, we have gone through all the relevant police checks and fingerprinting in a bid to obtain the licence as legitimate security surveillance service provider. This is a Class 2 corporate licence that enables us to advise on and install security equipment.

Why is security licencing required?

 

Basically, the security licencing is a constitutional requirement for anyone who intends to operate a security installation business, so any organisation offering the service without a licence is operating outside the law and could be arrested and consequently prosecuted.

 

Benefits to customer & What could happen if a non licenced contractor is used?

 

Once a company is licenced to offer security service, another unhappy situation sets in: not all contractors appreciate the law. And not everyone enjoys playing by the rules. Unlicenced contractors might be a more appealing option when comparing the financial estimates. Licenced contractors will charge more because they go through a great deal to earn the credentials, pay for insurance protection and hire qualified personnel who offer quality services. A non-licenced contractor on the other hand may have no insurance protection or qualified employees for that type of work. Furthermore, how can you be sure that this firm can be trusted to know the access codes to your workplace or home if they have not completed police checks?

My advice is; don’t take chances with your security system. Save your business the unnecessary risks and stress that comes with contracting cheap and unlicenced taskforce. Hire service providers who you are certain has gone through the police checks and earned the credentials of their trade and abide by good business practices. I guarantee you will stand a good chance of seeing your security systems installation job done right the first time.

Is your NBN line secure from vandalism?

2016-07-08-14-26-12

Its only fitting that we have another topic about the NBN. The bus is still rolling out and we are seeing more about it little by little. I am writing this particular blog because I am noticing that many businesses have their external NBN box mounted in such a place that is completely prone to damage from the public. The NBN has their specifications for the IK rating and IP rating (impact and weather resistance) and that is fine for the box itself, though it only takes one look at the installation to see that the cable coming in could easily be snipped or whacked and its all over red rover. At least until you get into the office on the next Monday and organise Telstra or similar to come out and make a repair. This could be days…

How much is that going to cost you in lost revenue though? A day or maybe three without internet and phones? It could cost you a bundle when you think about lost opportunities, bad customer experiences, lost sales. I don’t need to continue this list, you get what I mean.

Now who would want to do this? Criminals is a good place to start.

Many businesses do not have a 4G/GSM dialler to create an extra protection layer for communications between the security/CCTV system and the outside world. Relying on the fibre makes your external NBN box an easy target. More about 4G/GSM diallers in the next blog.

Beyond that is accidental damage: whipper snippers, shopping trolleys, office furniture anything really. Sometimes staff are not aware what this cable is, how easily it could be damaged or how important it is to the operation of your business. This type of thing can happen with the internal lines also. We have seen a number of instances where the internal fibre run has been loosely installed in duct stuck onto the wall with double sided tape. 2 months later the installation it is starting to pull away from the wall. To me this is not good enough and a poor way to treat possibly the most important tool for many businesses. The fibre cable that is used to enter the external and internal box (if you have fibre into the premises) doesn’t have all the extra protective layers like and underground or weather protected cable does. It doesn’t take much to damage these cores with a bit of a knock or a small kink.

So what do you do?

1. I would suggest having a look around where your external box meets the  building, look for any conduits or ducting coming up to meet the NBN box.

2. Secondly, see if you can locate the internal run. It may be visible, it may be concealed in a ceiling or wall space or even run in ducting across a wall internally or externally.

3. Think about things that may come in contact with it internally or externally. through business operations or outside influences.

4. Does it look like it needs physical protection or more rugged casing in some way?

5. Call us to discuss some practical ideas for protecting your asset to avoid downtime of this critical asset.

Here are some photos of installations that demonstrate how accessible these fibre cables really are:

 

In this situation your business phone lines could easily be damaged without any tools. This box is mounted at an adult’s waist height.

NBN Installations Part 1.

fibre cores

By now everybody this side of Ballarat knows the term NBN. I dont need to spell out what this acronym stands for. NBN is on everyone’s lips. Politicians, the press, phone companies, the business community and all the way down the line to the people. I couldn’t think of a P word for business community. Let me know if you have one…

 

Everyone is now talking about how they have NBN or are waiting for NBN or what form of NBN they will eventually get whether its home or business. Its a big project. (My fibre to the premises works great by the way). With such a big project there is naturally a range of topics and gripes flying around.

 

Now that many homes and businesses have their installations completed and connected, we are starting to see the methods that installers are using to get the job done quickly. This is obviously because the installers are wanting to cash in and get things done quick considering they are on a flat install rate whether its a five minute job or a 5 hour doozey.

 

There are some terrible installations around. All those things you learn as a tradesperson going through the apprenticeship seem to be going out the window when these NBN install jobs are done. Duct hanging off the wall after only a month of installation. What a joke it is. i need to be fair with this. Not all installations are poorly done. Though I hate to say it, when government funds are thrown around in great numbers there will always be hoards lining up to cash in. I don’t know who is expected to pay for rectifications. Probably the consumer unless they have a loud voice and a bunch of patience to deal with their provider.

 

So here is the question. Would there be a better way to handle a project like the NBN installation (talking nationwide here) than the way we have done it?  Does a project that spans more than one term of government need to be handled by another department which is free of the political football games that restrict funding?

 

Na forget that. You’ve probably heard enough about politics in the last 6 weeks.

 

Stay tuned for more posts about the NBN and how it affects your business. Let us know about your experiences with the rollout good, bad or ugly.
