Tim Saunders 0 Posted February 11, 2011 Hello, We have a fairly large installed base of CCTV cameras in an industrial environment. I want to start moving towards IP based video, and am looking for some solutions. First, I would need some sort of encoder that I could split streams onto LCD monitors, second I am looking for camera's that will hold up in a dusty high vibration area that can be either POE, or Wireless, third i would need something that would convert a CCTV signal to IP, fourth i would like the option to be able to randomly record any stream to a NAS. Any and all advice will be greatly appreciated. Thx, Tim Saunders Automation Specialist Canfor - PG Saw Share this post Link to post Share on other sites
Soundy 1 Posted February 15, 2011 Wow, that's a LOT to cover - fact is, there are TONS of different ways to make all that happen... depends largely on your existing system (cameras and displays, existing cabling, how much existing vs. new cabling will be used), the rate you want to migrate things at (all at once or in stages, what the stages are, etc.), and what sort of budget you have for all of this. I gather from your signature, you're in Prince George? Share this post Link to post Share on other sites
Tim Saunders 0 Posted February 15, 2011 ya i'm in PG. Those are the ultimate goals. I really want to end up with a complete IP based camera/monitor infrastructure. Except i will need to utilize/migrate the existing CCTV cameras and monitors, so it will be a gradual changeover. There isn't a lot of money to get this done so it'll be in stages. First thing, I want to test a wireless IP camera. I need to find out if the interferance will be a problem in the sawmill. If wireless proves to be fine, then all new cameras will be wireless. I would probably re-use the existing coax runs for existing cameras. Although if i could find a BNC to Wireless IP converter, that would be great. The coax cables with the BNC ends on them are a pretty big maintenance headache for us right now. I'm fairly new to the CCTV world and any suggestions are appreciated. Thx, Tim Share this post Link to post Share on other sites
Soundy 1 Posted February 16, 2011 I would recommend against wireless except as a last resort (ie. no possibility of wired connections), especially in what's sure to be an EMI-rich environment... and even then, using equipment designed specifically for this type of installation (ie. Ubiquiti, among others - not off-the-shelf WiFi). Unless you get into more proprietary systems, you'll likely run into bandwidth issues after more than just a few cameras. The beauty of an IP system is that you don't have to home-run every camera; you could, for example, have one switch in a given area for a group of cameras, then give them all a single run back to the NVR, or to another switch. Or, if necessary, connect the network segment itself via a single wireless link, instead of each camera having a separate wireless feed. Existing coax can also be used for IP transmission - I've easily run four 2MP cameras over a single coax by feeding them into a local switch, then using ethernet-over-coax adapters to uplink the switch to the network. Video encoders to "convert" analog cameras to IP are convenient, but from some of the preliminary shopping I've done, they cost almost as much as most VGA IP cameras and even start coming close to the cost of megapixel cameras - it almost becomes more cost-efficient to just replace the camera rather than "network-ize" existing cameras. More than anything though, it sounds like this project needs a LOT of advanced planning of where to start, what the stages will encompass, what needs to be done when... pity I'm 10 hours away, I'd love to have a look at the site.
