Bosch CCTV cameras

Bosch CCTV

Bosch security systems has now released a complete list of its full product range for 2010/2011

News on CCTV products.

They have been particularly keen to promote the new Auto-dome Easy II range, the extremely versatile IP200 series and the MIC500 classic (Metal Mickey CCTV camera).

Easy dome.

Starting with the Easydome II they have managed to produce a sophisticated range of dome cameras at a very reasonable price and very easy to install. Feature rich, this dome range is 70% smaller than a traditional PTZ camera making it compact and ideal for discreet surveillance. ONVIF compliant, with the option of on board analytics, the camera range has both internal and external options, well worth a look.

IP camera 200 series.

We have spoken a lot on this site about the IP 200 series cameras. Bosch have found a market place for this IP solution making single camera installations complete with recording a very affordable solution for small to medium size business. A popular application for this IP camera is reception areas or locations of high stock value where a full blown CCTV system would normally be cost prohibitive. Again ONVIF compliant with an on board SD card for recording purposes together with a free  CCTV software solution that is able to accommodate up to 16 cameras, The IP 200 range is defiantly one for the future.

Metal Mickey CCTV camera.

The MIC, Metal mickey has always been a high profile robust external camera. Used for solutions such as shopping centres, football stadiums, dockyards and airports, it is very versatile. Buoyed by the success of the Metal Mickey CCTVcamera in the Big Brother series, Bosch have continued to improve the design and performance, culminating in the MIC series 500 classic. Easy set up and reliability certainly make this camera one of the leading contenders in the rugged dome market place.

Summary.

In summary Bosch have always produced quality. There cameras produce excellent images and innovation means they will always be at the top of CCTV industry, night time images especially are an area of expertise and now clever analytics within their codecs mean the options for installers are ever evolving.

CCTV kit

CCTV kit.

Is there an argument that as an end user it is better to buy a CCTV kit from a wholesaler and then install the system either by yourself or get an electrician to carry out the work? Well it would save on costs there is no doubt about that. But CCTV kits available on the Internet tend to be imported from the Far East and tend to be of a lower spec than a CCTV installer would use.

Home CCTV.

For home CCTV it is defiantly a market that is growing, the average domestic customer is simply looking to install a CCTV system to enable them to see who is there without leaving the safety of the home. To this end the CCTV systems that are available in Kit form will suffice. Commercial users though often have CCTV cameras installed for more reasons than just observation purposes and this is where good recording and quality cameras will make a difference.

CCTV kits

Most companies have little or no resources to just have someone watching CCTV images, so inevitably all the information that the CCTV system gathers will need to be reviewed from a recording. This is where the main difference between CCTV kits and a professionally installed CCTV system will tell.

CCTV system.

A CCTV System in kit form will have little or no flexibility on the number of frames per second it can handle or the image quality unlike a more expensive DVR solution. Lets be honest though some high end spec DVRs can cost upwards of £6000 they will have many features and some of these would be over the top for many small or domestic installations.

Buy CCTV.

At the end of the day when buying CCTV kits you really need to think hard about why you really want it, to observe or to actually produce usable images after an event has occurred. Review what is out there and take advice. It could save you spending hard earned cash on something that at the end of the day turns out to be a white elephant.

Seagate or Western digital

Seagate  or Western digital.

Hard drives! Anyone in the IPCCTV world will tell you these are the only two hard drives that are really used in most digital recorders today. They will also tell you that both are the same , there is no difference, it does not matter which one you use. This is especially true of installers who buy their DVR’s from the manufacturers and install their own hard drives .This can save a lot of money. Most manufacturers will advise against this but all in the know realize that on paper it makes little difference.

But……….

However we have come across a case where it seems some DVR’s really do need the hard drive installed that the product has been tested on. Below we carried out a series of test on a DVR that seemed to fail for no apparent reason the results were surprising and indeed could shed some light onto why DVR’s seem to fail for no apparent reason.

The test.

Below is the findings as described by the technician who carried out the testing…………………….

“I have been undertaking an extensive test on the DVR to emulate some of the issues we are seeing reported in the field”………..

The issues we were hearing were:-

  • Alarms locking up the units
  • Rebooting
  • HDD / recordings missing

I have set up a unit and  over the last 2 weeks, here are the results of my tests:-

Seagate 1Tb ST31000525SV – 2 of them to make 2Tb –  DVR 400ips unit

  • 5 cameras connected (1 camera looped to 4 other inputs)
  • CCTV Camera 1 is set up for motion and also I have turned on Sensor 1 and set to N/O – basically causing the alarm to be permanently on
  • Cameras 2-5 are set for motion
  • Recording schedule set for motion and continuous 24/7
  • Notify set to send alarm data to an internal IP address………….my laptop,……….so not always there (testing to see if a non-connection will cause lockup)

After 1-2 days of me not being present, the unit shows the ‘no HDD’ symbol with a red cross through the symbol………..looking at the System info, no HDD’s are present………reboot and they still do not appear……..when I do a full power recycle, both HDD’s appear again, the system continues recording and all video recording is still present (up to the point where the HDDs disappeared obviously)

last week, I observed the unit reboot after 3 hours, and when I checked the System info, one of the HDDs had disappeared……..a couple of hours later, both HDDs had gone after another reboot

So, I had taken delivery of 2 x Western Digital 1Tb HDDs Caviar AV 10EVDS and proceeded to put those into the  DVR in question

It is now Wednesday (5days later) and the exact same test has been performed with no reboot, lockup or HDD / Video recording loss……………….this leads me to suspect the following:-

  • The Seagate drives we were using were a faulty batch (possible but unlikely)
  • The Seagate drives we were using are actually not fully compatible with the DVR firmware, even though the manufacturer gave us the part number (possible)
  • The Seagate drives were not correctly inserted  by the client and my changing the drives to another unit is purely coincidental and corrected the fault – again  unlikely

Conclusion , it would seem that there is some subtle difference between the hard drives that has caused the DVR to crash although in practice this is not really possible the testing proves that somewhere within the firmware of the DVR a problem has occurred with the original hard drives.

When we at integrated CCTV asked the engineer if he thought there was a difference between the hard drives he replied.

“No same spec should make no difference, hard to understand, the Seagate is a good make so its not the Hard drive just the way it works with the DVR”

Feedback.

Has anyone else experienced hard drive failures on your own DVRs that may in fact be caused by a similar problem? If so we welcome your thoughts and feedback.

CCTV maintenance,essential service or industry myth?

CCTV maintenance, essential service or industry myth.

For many years it has gone without question that when you buy a CCTV system then you also buy a maintenance package to go with it. The packages you can buy are diverse, however and you can go from 1 visit per annum to clean and test the system to an agreement that will cover comprehensive labour and parts. The choice at the end of the day is of course in the hands of the customer but ultimately to the installer the maintenance is sometimes crucial to ensure that after year 1 a profit can actually be achieved on the installation itself.

Dangerous game.

This for the installer is a dangerous game to play in the current market place. Cut throat pricing means margins are small to non existent, if the client decides against a service agreement this can cripple small to medium sized installers and many businesses have failed in the last 18 months trying to get jobs on the back of a maintenance package.

CCTV servicing.

This then of course begs the question how profitable is a CCTV maintenance agreement? Well it tends to go back to the kit that is installed in the first place. Cheap kit is inherently unreliable and we would never recommend its installation. The other trick of course is to install closed protocol equipment meaning due to software restrictions only the installer will ever be look after the kit and will sting you forever and a day every time you call them out.

Cheap kit…dont take that route!

Customers tempted by cheap prices often regret their purchase simply because  a) the kit does not do what it was originally claimed to do.  b) The CCTV installer is constantly out trying to fix it. Of course any company doing multiple visits back to installation will soon see any profit wiped out, they will go under and the end user left with a useless un-serviceable CCTV system.

Do you need maintenance?

So back to the original question does a CCTV system need a maintenance agreement? Well the answer is defiantly yes. CCTV can be very reliable but it is a critical requirement. When it goes wrong it needs fixing and fast, an agreement that does not include a “hot swap” arrangement means goods can be removed from the site for repair and not returned for long periods of time. So the company you use to install and to service is crucial. The whole concept of  CCTV maintainence agreements really does come down to one of quality. Buy quality in the first place and your failure rate will be low , When the product does fail the installer should have a stock item to replace it , this is only possible if the installer can make a profit on the install and this is only possible if the customer has the vision to pay a fair price in the first place.

Tough times!

We find ourselves in a climate that is pushing prices and margins down; this can only lead to poorer service levels in the future, choose your installer wisely, pay a fair price for good products and don’t fall foul of cheap deals it may come back to bite you!!!
