IP vs Closed Circuit Security Systems?




Nika


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It's a beautiful new home and I don't want to make it seem ugly or outdated with an older system but I want what's going to deliver the best in terms of reliability.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.



Answer
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!

Does anyone know about this? ?

Survelliance Cameras?
I have asked this question before, but recieved no answer. I am wondering how good are surviellance cameras at night, with not a lot of light. I am asking about fixed positioned cameras that you see on the side of most building, that are not monitored by a person. A camera that is unable to zoom and pan. Without a person monitoring them so they can zoom in are they able to get good images, such as facial features, or are they more of a deterrent then anything.

I am trying to inquire information, to see if it would be worth using outside of a friends bar were cars have been getting broke into. The parking lot does not have many lights. So would this even be worth it without adequate lighting. I would like to be able to identfy the suspect since our police dept. does not usually respond to these calls unless it is in progress.
Would a camera like this be good enough to identify a suspect from a distance of about 20ft. Most footage I have seen on the net and tv, and from experience don't show real clear pictures, unless it is zoomed in. Is this the norm, even in the day time.



Answer
You can opt to use a home security video camera that records in black and white or in color. You can also buy cameras that have other features. Some cameras can record activities in complete darkness using night vision. This is great because intruders will not be able to see the exact placement of a home security video camera in the dark. Night vision technology itself has also advanced and can now record video in the dark in full color as opposed to the green colored night vision of the past.
