What is the RANGE of a 12V, 1Amp power supply of a security camera?

Q. Hello guys, Im connecting a security camera (12V 0.45A), but the cord of the power supply is too short (4 feet) and I need to make it longer. If I buy a male-female jack extension, lets say 35 feet long, will it loose power?


Answer
Short answer: that won't be a problem.

Technically, yes, the extension cord causes a bit of loss due to heat, resistance, and other factors. But a typical 120V 15A home outlet can supply more than enough power to cover the loss.

You have more to worry over the cord's placement than you do about its performance.

Iraq security issue?

Q. I was wondering why this Iraq pullout has to be so difficult, or better yet why is it so hard to implement any security measures for the area. I was having a discussion with a friend of mine about the security issues in Iraq and how best to resolve them, When he suggested that they should install security cameras like the ones in great Britt you would then be able to track all suspicious activity and the cost could be handled by the country's oil resources
this seemed like the perfect solution to the problem especially the problem of car bombing and the placement of IED's as they could easily be tracked back to the source. there is a saying in the army "keep it simple stupid" and this is as simple a solution as it gets. please let me know what you think


Answer
It could work in the future, but not know.

One example of what they use here is number plate recognition software. In Iraq, because of the lawlessness there, number plate recognition would not be of any use. In addition, it is easier to keep track of terror suspects because they make up such a small percentage of the Muslim population which itself is not that large a percentage of the UK population.

In Iraq, the country is almost 100% Muslim, and lots more are involved in suspicious activites. There are too many people to try to keep tabs on, and also too few trustworthy people to do this.

The security forces are infiltrated with those who are keen to attack the very forces that are in Iraq to help Iraq and the Iraqi people. They are going to cover the tracks of those involved in terror attacks, not expose them.

Last of all, because of the poverty and lawlessness there, any cameras would soon get nicked!
