i doubt there is any chance of sending HD quality video over wireless, let alone multiple cams not just one. just seen http://www.youtube.com/watch?v=X3Sy1YPvkoY i'm guessing even the router they show must be a gigabit router as opposed to being the standard router.. and then imagine...

quality is so good i think i agree - forget about 4 cams with 8-cam upgradability lol, i'd rather go for a proper DVR and one cam for now, can maybe treat myself for xmas with another 2 later on! one confusing thing about adverts is - although teh DVR may support HD-SDI, whether that's...

phew thanks thats blo0dy annoying now! - the quality is worlds apart!! thing is, the price is too! back to teh drawing board...

thanks, hence my thinking of 25fps recording at 704x5xx TVL? is that resolution not enough u think?..

hi all, I am contemplating on fixing a CCTV system for my house. just a few days back my neighbour noticed a scumbag who hurriedly left our shared drive as he drove in, around 9.30pm! prevention is better than cure is my thinking. have researched a bit on this subject and as i understand...

sorry i'm a bit late for the party, i do have the same requirement - to fix a cctv to my house before some scumbag decides to break-in!! having read through, what i have learnt is to look for something like below: - a DVR with ability to record minimum 4 channels at 4CIF quality...

thanks

some boilers have a small hot water storage capacity. one example is the Vaillant 937. they provide instant hot water by having heated water in a small storage tank in the boiler. question is, what if the water has not been used for a while? the water in the tank would then go cold...

Thanks, I know the air vent. Opened it - no water! Switched the boiler on momentarily - air! Tried it a couple of times but its very time consuming as its a pin-hole vent. So now I know a definite fault, although I'm still not sure why it causes such a massive banging noise and shakes...

Update: Tested the waterflow with a mate in the airing cabinet monitoring the water pump and valves. The flow pipe gets blistering hot. Water pump works though and ultra hot water flows upstairs to the airing cabinet as well. Yet, the boiler makes that massive banging noise and goes...

thanks there is water in the tank. if i touch the water pump it seems 'normal' (very slight wirring feel to the hand). so the next suspect might be the heat ex-changer.. how do i check that the water flow? from the flow pipe being very hot and the return being cold? thx

Thanks for your analysis and feedback. I have just climbed the loft and the F&E tank is full. I have a question though: As in the video, every time there's a banging noise the flame goes yellow. with the final 'bang' it goes dead. how can a blockage in the water system cause that...

All, help pls, no heating since yesterday! captured the issue on video as below: http://www.youtube.com/watch?v=MnkD9dYJVQY - I have removed and tested the air fan, it is working perfectly and as you can see on the video as well. so its not the air fan gone belly up - water pump...

i have bypassed the kitchen tap and the garden tap anyways. so they remain hard. my preferred route would have been to fit a 3-way tap in the kitchen. i didn't cos: on one side the type of design i have is about £500 for a 3-way!!! on the other side is the potential that the wrong water...

cheers john, i thought the same re metering: it surely must be some rotating fan in the waterway turning as water flows. and not a 'clock' based timer. afterall these are water pressure powered devices... so in effect combi or old fashioned boiler - either way, the regeneration would depend...
