Speaking strictly for myself, I despise batteries.....really, I do.
In the form for cctv or in gernal?
I'm already using a cheap no brand AliExpress camera for this, so not much loss. I call this whole project more fun than the actual result.
I'm wondering how reliable the cable will be long term.
While i know they make stranded cable for flexibility most network cable including the outdoor stuff is a solid core. With the tree and branches blowing about movement over a period of time could lead to failure.
Why not substitute the tree for a pole and a guy wire to the bird box or house. Cable tie the network cable to it to take the weight. Should be less movement and less strain on the cable overall.
I suppose it depends on how you have interpreted my message
. There are some big trees with really thicc main trunks that don't move at all in strong winds and then there's little bush things.
But you are correct in this case, the tree right next to the house is a small bush thing. Which is great to hide the cable going up it.
First instance I'll attach to the tree and see how I even like the birdhouse cam, latter on I can think about a pole.
I totally agree with a pole, it would get hidden in this ever-green tree fine.
Please do get back to topic for OP, I don't intend to take over about my birdhouse!
