Also mentioned is the cost of setting up sites, ranging down to as low as US$2000.   It would be nice to have somebody or company sponsor a webcam on the new hide ! « Last Edit: May 4th, 2006, 12:57pm by Webcreeper » Logged Lynx BBS Member BBS God     Posts: 429 Re: Webcam « Reply #1 on: May 2nd, 2006, 6:33pm » Quote Modify My own experience is that the installation cost for setting up a webcam at wild site is around HK$50000 - HK$100,000, depending on the physical conditions of the site and what kind of picture you want to get.  The major problem is the remoteness of Mai Po birds hides, in particular at the mud flat, which is far away from existing electricity cable and data transmission cable.  The solution is to go wireless using 3G or GPRS transmission for the video capture.  The webcam can be powered by solar batteries.   « Last Edit: May 2nd, 2006, 6:34pm by Lynx » Logged Welcome to Lynx Aviary http://www.9014316.com/birds.htm Fred BBS Member BBS God Birds are fascinating!     Posts: 254 Re: Webcam « Reply #2 on: May 2nd, 2006, 6:57pm » Quote Modify Good ideas!   With both 3G and regeneration of energy being hot topics at the moment, we have good chances to get sponsors.     Logged Bob Thompson BBS Member BBS God I love bird watching!     Gender: Posts: 433 Re: Webcam « Reply #3 on: May 2nd, 2006, 8:31pm » Quote Modify China is a leader in these topics, so surely we can get some one to come forward and sponsor the webcam. Looking at overseas webcams the sponsors get great exposure with there name(s) on the web page. You don't buy much media time for $100,000 these days.   If we could get as many hits as lamma.com.hk (1,000,000 per month) the outlay for a sponsor is very little, in terms of advertising exposure Logged Lynx BBS Member BBS God     Posts: 429 Re: Webcam « Reply #4 on: May 2nd, 2006, 9:38pm » Quote Modify Before being getting too carried away, my preliminary assessment are as follows:   1. The cheapest solution is to install the webcam at either the warden's hut, WWF Peter Scott Field Studies Centre or the Education Centre.  I presume that both electricity and telephone lines are available at the building and so power and boardband connection are tere.  All the setup costs involved are only the cost of the webcam, which a few thousand HK dollars will get you a decent one with 1M+ resolution.  For $15,000, you can get a night-vision one!   2. The second alternative is to install the webcam along the FCA road.  As there are light posts, I think electricty power is okay.  But data transmission is a big problem because laying a new dataline is ultra-expensive and will cost you more than $100,000 for just connecting a few hundred metres of cable.  The solution is to go for wireless 3G or GPRS transmission.  In this case, a system controller equipped with 3G/GPRS modem chips is required which will cost around $10,000-$20,000 more, in additional to the webcam.  But in Mai Po, my experience is that the mobile phone transmission is not good enough.  Therefore, the image transmitted by wireless means may not be stable.   3. The most expensive one will be installing the webcam at the birds hides.  There is neither power nor telephone cable.  In addition to the wireless modem, you will need solar batteries which are quite expensive for industrial grades that generate sufficient powers for modem and webcam.  What I worry is that birds' dirt may cover up the solar batteries very soon.
