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.

IP vs Closed Circuit Security Systems?

Sorry if this is the wrong place to post this.
I'm looking at pricing a security system for a client (new construction) and I'm seeing a lot of companies offering IP based systems and controlling everything from the cameras to lights with it. It all sounds nice and convenient but is it really worth it? How reliable are these types of systems? If you lose power or if you get a virus while you're connected to the internet, does your whole system fail? Is it better to stick with a more "old fashioned" closed circuit system for reliability?
It's a beautiful new home and I don't want to make it seem ugly or outdated with an older system but I want what's going to deliver the best in terms of reliability. Does anyone have any thoughts on these system and/or maybe have some good suggestions for systems I should look into? I'm not opposed to IP, but just want to be sure that their safety won't be compromised for the sake of looks.

Nika, it sounds like you're really looking out for your client- Good for you! You have several concerns:
First, you mention that this is new construction. I recommend hardwired cameras, regardless of technology (IP vs. CCTV). Hardwired is always preferred to wireless whenever wiring is an option.
Next, IP cameras are very reliable, as long as they're installed properly. Any video network you have will be behind your router/firewall, so it should be protected.
During a power outage, most video systems will be down, unless you run all key equipment on UPS power. If you're viewing video on the home's televisions, these will lose power anyway. You could still use PC's or laptops with battery power, provided the DVR or other video switcher has back-up power.
Modern cameras of either IP or CCTV design look pretty much the same, and won't detract from the appearance of the home. Placement affects this, more than the cameras themselves.
As far as whole-house automation, standards are still evolving. I advise finding a company with a good track record in home automation. Ask for references, jobs they've completed, photos, etc. If they specialize in home automation, they're more likely to handle any compatibility issues with various video, lighting, and other controls.
Good luck on your build, I hope it turns out great!
