CCTV Over wifi

Posted on by

we have blogged before about sending CCTV data over wireless ‘units’

today, we take a look at Silvernet, a great little UK company specialising in Professional Wireless solutions.

Silvernet offer various products to take a straight forward ethernet connection and send it wirelessly over to a receiver and back out to join a LAN setup.

Offering short range LoS (Line of Sight) solutions such as the Sprint A5 1Km LoS (54Mb Link) and also long range (20km+) solutions mean that Silvernet can offer great kit for a variety of installations

We’ve seen some of these units in action and cannot fault the ease of installation, ease of set up and ongoing reliability of their kit…………

let us know if you have used Silvernet’s kit before and how it has helped in applications where cabling is impossible!

HD cameras – can they be the same?

Posted on by

An interesting demo came up recently…..

we took a few cameras, HD 1080p to be precise, from a very renowned IP Manufacturer,,,,,,,,,,,

a couple were mini dome based, the type you see in the analogue arena, you know, Vandal Resistant with varifocal lens, 3 axis, day night etc etc

the others were ‘boxed’ cameras……..the type where you fit the lens, usually (and recommended) a high quality lens designed for Megapixel use………

putting them side by side, adjusted to look at exactly the same picture………….both 1080p cameras from the same manufacturer………..

The Result

well, both were excellent pictures – it cannot be denied – but, they were not identical……….not by some margin………. the mini dome was ‘softer’, a little more ‘noise’ in the picture whereas the ‘boxed’ camera was sharper, more ‘vivid’ colours………….electronically zooming in revealed that actually, the mini dome, despite the ‘noise’ was actually a sharper picture, the ‘boxed’ camera had a degree of ‘pixelaion’ which detracted away from the initial sharpness………….

turning the lights off to test the day/night function highlighted the difference again………..the mini dome wiped the floor with the ‘boxed’ version camera!!! that puzzled us !

talking with the manufacturer, the mini dome is a smaller lens, smaller sensor, limited in optics to fit inside the dome………..that we can understand……….but how was it better under low light??

Lesson learnt

so, it is imperative that when specifying a system, particularly with IP MEgapixel, be aware that even with the same manufacturer, you will sometimes see a difference in picture rendition………..

what are your experiences?!

Emerging Video Technologies – IP Cameras (Standard Definition) Pt2

Posted on by

Taken from the ‘Emerging Video Surveillance Guide 2010’ from http://ipvideomarket.info/

Potential Benefits: The most important advantage of using IP cameras is the ability to directly connect these cameras to an IP or computer network. By contrast, analogue cameras require the use of an additional computer (usuall either an encoder or DVR). In certain scenarios, using IP networks can significantly reduce the cost of installation. In general, the greater the distance that video needs to be transmitted, the more likely IP cameras will be beneficial.

Remote viewing of video, though generally marketed as a benefit of IP cameras, is really not an advantage compared to many of today’s DVRs. Whether one uses analogue cameras and DVRs or IP cameras, video can still be viewed remotely with only minor technical differences.

COST: IP cameras usually cost 30-70% more than equivalent analogue cameras. These costs are often more than off-set in larger scale systems or when the cameras must stream video over great distances

  • End User Risks: While the technology is fairly mature, the main risk lies in operational / integration issues. Risk no.1 is that existing recorders do not support IP cameras or only support a very limited type of IP cameras. Risk 2 isthat the existing IP network in one’s facility is insufficient to handle the IP cameras through lack of bandwidth (although, this risk is rather easy to overcome in most situations)
  • Installer Risks: Lack of technical skills on an Installer’s existing staff is the strongest risk to deploying IP cameras. With traditional electronic security systems, an installer may find it sufficient to have only 1 or 2 highly trained IT Technicians (out of a staff of 10-30). However, with IP cameras, a far greater percentage will require IT skilss to conduct even the most basic installation / service activities.

What are your opinons??!
