FredB 0 Posted June 23, 2005 We just finished a 26 camera job, replacing all old cameras with new ones, and adding a few more. Put in 2 16 Channel HUNT DVR's. Have a few problems , with scrolling lines. Haven't really tried to fix it yet, but would could be the problem? Never really had to worry about that before, because all our systems have been up to 16 cameras, and have not had any problems. Bidding on a job with 64 cameras tommorow (replacing 4 16 channel multiplexors and the cameras in a hotel). Couple of questions on these bigger jobs and how to approch them: 1. 12 or 24 Volts? Thats the least suceptible to ground problems etc? What other benifits are there? 2. Individually isolated power supplies? http://altronix.com/index.php?pid=2&model_num=ALTV2416I Does it make a difference when it comes to ground loops/ problems etc. On these big jobs I would much rather spend $100 extra to get a great power supply if it means less chance of a headache. 3. What is the best way to control so many cameras without spending a zillion dollars on a pelco matrix system, or a Dedicated Micro system? Need 4 good DVR's that you can control all the functions from a camera controler. Nuvico is coming out with one, but it is a few months out. Suggestions please!!!

qman 0 Posted June 23, 2005 How about a Toshiba Survellix 64 Channel DVR? Great unit. Share this post Link to post Share on other sites
rory 0 Posted June 23, 2005 Stand Alone ... GE has the KTD-405 controller Keypad, allows you to control hundres of DVRs. Or use the Network Software and get 64 Camera multi DVR view. They also have a matrix type DVR set up called DigiPlex. But like you said they are big dollars. Hunt has Multi Site network software also but not more than 16 cameras at once. Toshiba is a PC based. By the way, we are switching out a Bosch Desa PC DVR for a GE DVMRe next week .. so will have the Desa to play with. They wanted the size of the DVMRe and didnt want to use a mouse or keyboard... wanted simplicity and stability. 12 volts DC seems to have less issues, but 24volts AC is better for other reasons.

FredB 0 Posted June 23, 2005 Did soe research about the subject and it seems the matrix system is the way to go, specially if you have mutiple monitors. Wondering though have the DVR would interface with the system? Like a multiplexor type way so it would only record every 24 frame in a 24 camera system for example or...? Individullay isolated channels on a power supply or...? Share this post Link to post Share on other sites
rory 0 Posted June 23, 2005 The GE DVMRe-CT has 2 Multipleview Monitor Outputs and 1 Spot. You can link them all up just like you can link their muxes. The Digiplex (Matrix), yes, you would need single channel DVRs along with it so it would act like a mux recording to a DVR. You loose some network functions like Multi-Site (can only remotely view 1 DVR at a time in one instance of the software). They have a 32 channel Matrix System which is less expensive, to some degree. Matrix is actually old school, but with the single channel DVRs and disk space up to 2TB it still gives you alot. I have a client with 10 camera mux and a DSR2000 single channel DVR, 640GB, gets 6 months on 5pps, motion detection. They have the DVSe which is additional digital storage that can be added to the DVRs and you can also connect to them. This is GE anyway . .. the others not sure. Ultrack has some good matrix systems, used to use them for most casinos, but casinos have upgraded to PC based now ... some of them anyway .. even GE now makes Casino DVRs which are PC based.
