Hi

I'm going to purchase a Orion 4 camera DVR (SC144)

The situation I have is that it has a VCA output, I have to TV's I want to plug it into at the same time one is a small tv that will be on all the time then occasionally I would like to turn on the big tv and watch it when I want a bigger picture. So my question is would a VGA splitter do the job and if so what's the difference between just the cable splitter and the powered box unit ones. And also will it effect the quality at all if so how much.

And if anyone has used these Orion DVRs how have you found them?

Any help would be hugely appreciated.

To split VGA or composite you need a powered splitter.

No idea what model you're looking at but if it's like most low end CCTV systems it'll be very average - there is quite honestly no reason to install analogue gear these days when IP CCTV kit is so vastly superior.

Okay thanks, how come a non powered one won't work?

sbiddle: there is quite honestly no reason to install analogue gear these days when IP CCTV kit is so vastly superior.


Devils Advocate:The SC144 IS cheap

That said, I'd never touch it.   My journey messing about with home security started with setting up a couple of cheap network cameras with software running on a standard PC.  However I've ditched that in favour of the Unifi Video/Airvision products.   They are the correct combination of cheap enough and 'good enough' for me so far, and I'd not bother with anything cheaper/nastier.   But I could be sold on something better.. if it's out there.

You can get them from these guys http://www.gowifi.co.nz/ubiquiti-networks/ubiquiti-aircam-ip-cameras.html and you don't have to buy the NVR if you have a PC you can install the NVR software on.   Be aware the NVR software isn't just a tiny utility.. it does load the PC up a bit.

So there is my 2c

Okay thanks for this, this is just going to be used for home use so didn't want to spend money, the great thing is I don't have to tie up a computer with it and I can watch it remotely with an iphone app

Just dont portfoward to a cheap embedded linux DVR, Not only is it insanely bad for security, they will lock up all the time with the constant hammering they get from the internet of people looking for interesting things.

port foward is when you open your DVR up to the internet and access it with either a static IP or a dynamic DNS name, so anyone online can get to its "authentication" page by just connecting to your external IP address.

Passive splitters are a waste of time - they simply result in a worse picture quality as their is no amp, and more often than not won't work as EDID can't identify the monitor type.

When you can buy an active splitter for NZ$15 it's not like they're expensive.

Any computer retailer should have them. I would recommend PB tech because I have seen them on the shelf there.
