Smart, compact, reliable and neat. Just a few words that have been used when describing the Samsung SRD1630. This 16 channel DVR is able to hold up to 6 internal hard drives meaning storage is never going to be an issue. The SRD 1630 is also able to support a smart phone for remote access. H.264 compression and a linux embedded operating system are also features of this DVR.
Buy ANPR cameras.
When looking to purchase ANPR cameras there are several features you should ensure that they include before you buy. Remember, picking up number plates is a pretty tricky task and all sorts of considerations need to be taken into account. The speed of the car, the the lighting conditions , sunshine and reflection. The position of the number plate on the vehicle and so on.
To set up ANPR cameras correctly, the position of the camera in relation to the vehicle number plate is crucial so the first thing we would recommend that you ensure your ANPR cameras include are a zoom lens feature. There is generally two accepted distances you should position the cameras from the target number plate. These are 3-12 metres and 8-20 metres. To ensure a capture rate of above 98% the camera must be high resolution. The Sony EX view is an accepted ANPR camera module used in most versions of the best number plate recognition cameras on the market. In order to get the maximum reflection back from the number plate itself all the bests ANPR cameras come fitted pulsed IR led illumination. This reflects back from the special material used on number plates and means that even when you try to capture the the numberplate head on with the vehicle lights on full beam, the camera is able to filter out the white light and home in on the number plate text itself. This is called optical filtering.
The golden rule of ANPR cameras and they key to their set up is that the a full on view is is the best . If you have to set the camera off to one side and create an angle then the number plate in relation to the camera becomes distorted making it far more difficult to read. As a result the rule is that the camera should be no more than 35 degrees off set from the number plate. The simple reason for this is the IR will not reflect back into the camera lens if there is an any greater angle.
ANPR cameras can also come in many guises, one of the most popular though is the bollard camera , the ANPR cameras will sit in a weatherproof housing and capture number plates with a high performance unit that has anything up to a 1/10,000th of a second shutter speed this ensures that captured plates appear razor sharpe.
Of course the ANPR cameras are useless unless running in the background we have some highly efficient ANPR software. This software is generally run on a PC that will sit in a cabinet adjacent to the ANPR camera system . This ANPR software can be networked and programmed to hold 10’s of thousands of number plates within its database .The software can be used to manage speed, overstay, non returned and banned vehicles.It can open gates , integrate to weighbridge software or time and attendance packages. ANPR software can be modified to welcome customers or used as a defence against terrorism. It is a very powerful tool and one that is finding more and more applications especially here in the UK.
So in summary if you want an ANPR camera system make sure you ask your provider about all the issues outlined above.
VideoIQ have come up with a fantastic IP network camera and an excellent solution for recording IP video. The iCVR IP network camera is armed with an on-board recording facility that lets the camera itself record on the edge of the network this serves the purpose of eliminating the need for an NVR or video management software.
The IP network camera itself holds all the intelligence and by using on board analytics this IP network camera can both produce and record High definition images and can store these until called upon, meaning the network is left to simply retrieve images when the need arises, as a result bandwidth use is reduced to the absolute minimum. With the need for a central storage solution eliminated and advanced analytics that are able to learn events and increase accuracy over time, the video IQ IP network camera simple to both install and operate. It would seem that recording on the edge of the network is the way forward and Video IQ are well ahead of the game.
HD SDI DVR review.
HDCCTV has arrived in the UK and is here to stay. That is the opinion of Benchmark magazine that recently reviewed the Everfocus EPHD08 HD SDI DVR. They were able to carry out a full test and review of the Everfocus offering and came up with some observations that were most interesting. The unit they say was well made and was simple and quick to set up. Installation was easy and the Picture quality was most impressive.
However their summary that HDCCTV will break the mould when it actually comes to sales really made us sit up and take notice. HD they believe will turn CCTV from what has always been a grudge purchase here in the UK into a desirable product. One that end users will actually seek out and look to buy.
Combine hd and analogue CCTV.
They ease of installation and the fact that a hybrid approach is possible ie a mix of analogue and HD cameras means that a targeted approach to where the HD cameras are used is quite possible, in fact this hybrid approach is a positive benefit. The cameras tested with the EPHD08 HD SDI DVR were the EQH5200 box camera this gave a 720p image and this was deemed quite sufficient in fact preferable to the 1080P offering.
EPHD08 how does it rate?
So how did the EPHD08 actually rate? Well Benchmark gave the unit the following scores and from the write up they seem fairly confident that this HD SDI DVR will be around and selling well for some time.
Product design 88%
Features and functions 85%
Ease of install 88%
Image quality 87%
performance 87%
Overall score 87%
so all in a great score and one that will put HD CCTV on the map here in the UK.
HDCCTV
Plenty of Pro’s…..what about the Con’s??
1: cable distance of 100m or so………so what, IP is 90m and HDCCTV can be repeated with repeaters
2: maximum 2MP…….again, kind of so what – majority of IP sales are in and around 2MP and any higher might often be wasted or not utilised…..more bandwidth and bigger file sizes and just exactly how far do you need to post-zoom!!!
3: lack of suppliers – ok, we concede on this, there isn’t a massive choice, but its improving daily
4: only uses certain coax – again, a bit of a myth – sure, the better the quality the longer the run, but HDCCTV will work on pretty much any reasonable coax cable
The fact is, it is difficult to really count the Con’s….. HDCCTV is a credible upgrade solution to existing analogue systems and is far easier to implement than IP due to it’s ability to utilise existing cable infrastructures.
The recorders appear to be more expensive than both analogue and even IP competitors, but I wonder how much of that is ‘new technology’ price premium??? Wth greater acceptance and higher sales volumes, those prices surely must tumble?
And maybe the labour/cable savings outweigh the extra prices of the recorders??
The cameras seem reasonable, certainly on CMOS anyway, and again, prices are usually dictated by volumes…
So, it’s very simple, to drive price down then acceptance and use must rise….. And with so many Pro’s and very few Con’s then it surely is only a matter of time!
