Feisty 0 Posted June 16, 2011 Here's the scenario: If you look into this site ( http://www.geowash.com/ ) there is this car-washing device that is being attended by car wash attendants. I want to install a wireless CCTV camera on every geowash device (maximum of 40 units) in a car park area so I can monitor every car being serviced by every machine. Note: 1. I don't want to install any wired CCTV inside the car park area since I cannot get a building permission for installation. Here's my requirement: a. Wireless CCTV camera - I want to use 5Ghz band or if you could recommend me a better 2.4Ghz, it would be fine. b. NVR - For digital storage (2-3TB) c. A central AP where this wireless CCTV cameras can connect e. 12V power f. CCTV size must be considered because they are to be attached to the car-washing device. g. For monitoring purpose only.

Soundy 1 Posted June 16, 2011 I don't see wireless being particularly feasible here. Basic analog wireless systems are toys at best; the only way to do it right for any kind of reasonable budget is with IP cameras and specialized WiFi systems such as Ubiquiti... and even then, any workable wireless system, analog or WiFi, will depend on line-of-sight connections to work properly, something that could tricky if you're inside a concrete car park. You could MAYBE pull it off with a combination of wired/wireless - access point near each wash station, wired back to the NVR - but I still think it would be tricky to get everything to work properly. A better option might be cameras with onboard storage to record internally, so all you need to do is power them locally. BTW, two of your criteria are contradictory - item G says it's "for monitoring purposes only", but item B calls for a big chunk of network storage. Which is it? The suitable options will depend largely on this. Share this post Link to post Share on other sites
Feisty 0 Posted June 16, 2011 Yap, we were just analyzing the wireless connectivity item and it seems not feasible with this kind of situation. If ever, we might need to provide a waterproof camera since this is a water-carrying machine. We're still finding a correct/acceptable solution where we can monitor the number of vehicles being serviced in order to eliminate the car wash guys from cheating on payments. We opted to operate wirelessly since cable pulling cannot be implemented for we need poper authorization from the building management. It's for monitoring and we need to save it on NVR's for reviewing purposes. Share this post Link to post Share on other sites
Soundy 1 Posted June 16, 2011 Well, if the site layout supports it, you'd really only need a couple/few high-mounted overview cameras to keep track of what's going on... that could make a wireless solution more reliable, if you can arrange things line-of-sight. Keep in mind though, you still need to get power to the cameras... and wireless itself will suck a lot of extra power. How hard would it be to get permission to hardwire? Even if there's some existing structure (beams, pipes, etc.) that you can strap wiring to without making it "permanent", that would allow some stationary overview cameras....

ChrisP 0 Posted June 23, 2011 Feisty - I like the design of your site. I think you can do wireless point to multi point 5.8 wireless transmission if you have line of sight. I have used wireless ip raidos in the past and I had no reliability issues. Share this post Link to post Share on other sites
hardwired 0 Posted June 24, 2011 Can you share some more information about the construction/size of the car park? This could be feasible, but would possibly require locating multiple AP's in the structure (if you can't wire cameras in the building, you might not be able to wire AP's there, either...). Also, we'd need to know the battery capacity of the carts, to see about the additional load of a camera and transmitter. If the carts are all moved to a centralized location for charging overnight, you might be able to use cameras with onboard storage, and then offload it it at the end of the day while charging.

fa chris 0 Posted June 24, 2011 Have any pictures or a sketch of the layout of your site? There might be some other possibilities. Sounds like you need a vehicle counter at each bay more than anything else. Share this post Link to post Share on other sites
