Hi Guys, hope you can help? I have two day/night cameras about 270 ft away from the dvr equipment and it needs to be powered remotely from the dvr end.. The cameras uses about 750mA max @ 12 Volts Dc. Should i go for 12V dc Or 24V AC with a converter on?? & what size siamese cable should i use??

hi, Does anyone know what is the best way to mount a camera onto a tree with a trunk about 5 meters in diameter? I have thought about using screws but will this kill it?? The tree is about 30 years old and about 30 meters high. Thanks

Hi all- thanks so much for the replies- how embarassing that I said the diameter was 5 metres- I actually meant the tree circumference. My apologies- I have also never seen such a gigantic tree. Thanks again!
