Avigilon JPEG2000 70 dB dynamic range
thewireguys replied to cglaeser's topic in IP/Megapixel Cameras and Software Solutions
Are you becoming a dealer/installer now? FYI it does that with any camera not just the JPEG2000. -
Power supply and fuses..... If your power supply fails for your HDcctv cameras you lose everything. With IP you can have redundant switches and redundant power supplies for those switches.

This makes me laugh every time i watch it...... " it prints money.... I don't care" PS i have the EVO

Recommendation for IP Camera and Mesh Network
thewireguys replied to amani's topic in IP/Megapixel Cameras and Software Solutions
I install both VideoIQ and Fluidmesh. Both are great products that do exactly what the manufacture claims. I will say Fluidmesh is a little over kill for simple PTP links across parking lots but it is expandable to MESH system and is not standard Wifi solution. Install, setup and network monitoring is simple. -
FYI if you plan on using 10GB networks you need Cat6A. Cat6 will only work for distances.
-
Sounds like a service nightmare. How can you be great at anything if you do everything?
-
Well that's it HDcctv has an advantage with latency.
-
So you don't think that your choice of Codec has more to do with latency then the network itself? I think your choice of codec may produce "processing latency" but - that occurrs prior to or after entering or exiting the network pathway. Network latency would also account for time taking by the hardware to process the data. So on top of network latency, you also have processing latency, which is not only affected by your choice of codec, but can be compounded by your choice of operating system as well. So then you understand why HDcctv doesn't have latency issues.

Could you expand a little on how a closed dedicated network system for CCTV is a lot more valuable and useful to the end user than a closed dedicated RG59 network for CCTV? I shouldn't have to I feel like your probing us for information.
-
90% is high. a cctv network should be dedicated all brand new and not used in connection with anything else. along with good switchers. that way latency is so low its not worth talking about In the scenario you describe , yes 100% ---- in addition, that means it remains a security system with limited access! Build a dedicated network for your IP security system..... same thing as a dedicated rg-59 network for analog cameras just a lot more valuable and useful for the end user. Question tesc_cctvpro Do you think most of the latency comes from the network equipment?

I am not scared at HDcctv at all and I think it could be a great tool. I have a HUGE problem with how the HD cctv alliance rams false information about everything down people's throats. They have done nothing but turn people off with their tactics and lies. Companies that not embrace IP will be left if the dust. EVERY Device is coming with an Ethernet port or Wifi including HDcctv DVRs. HDcctv will not compete till it is the same price and Qsee and other crap you can by at SAMS club. Also I have many jobs going on right now (small and large 175+ camera jobs) and NONE of them are a good fit for HDcctv. Last time I talked with HDcctv alliance members they say HDcctv designed for the 16 channels and under market. I think HDcctv is not a step forward its just anther tool we can use if we need zero latency system for live viewing but it is a long way to go and IP is getting better and cheaper every day with many years of a head start. Also I have talked to a manufacture the designs and manufactures IP and HDcctv He clams HDcctv will never be cheaper to produce.
-
I think what everyone is saying if you need zero latency HDcctv is the best choice otherwise IP is a better option. IP has better system scalability, design flexibly, and system options which I think is more important to almost all customers over latency.

HD cameras' time delay comparing to Analog camera?
thewireguys replied to Sooki Choi's topic in General Digital Discussion
What type of customer are you talking about. -
Here you go check the specs on this camera... Min. Illumination.....6 Lux(F1.8/ 50IRE/ TV=1/30sec.1920x1080 movie) http://www.sgdigital.com/sgd-22sd1.htm
-
Sorry I am not posting pricing or giving out free system design. Also why 4 to 8? Why not 5 and 9?
-
OK I do that every day. Not a problem at all.
-
Totally different. How would you "lost too many frames"? If you design the system properly and use quality equipment this is never an issue. You drop frames from bandwidth or HD issues nothing to do with latency.

Sanyo HD 4mp Cameras
thewireguys replied to EarlT's topic in IP/Megapixel Cameras and Software Solutions
Rory that 1080P looks better at night then those CNBs.... If I need more light I can add IR or While light it's really not that difficult. -
Sorry I disagree
-
Latency has nothing to do with FPS. Latency is a measure of time delay experienced in a system. Example... You press move PTZ right how long does it take till you see the camera movement in the video.
-
Anyone thats used to no Latency for the past decade or so? I have had zero complaints from any customers.
-
Should this be moved to the dealer only section?
-
HDcctv definitely has an advantage with latency but how many customers need this besides casinos?
