Embedded DVR's Hardware specifications.

[kandcorp 0]

I would really be interested in how Stand Alone Dvr's are commonly and uncommonly manufactured in regards to hardware configuration and specifications. How do they measure up performance wise to PC-Based DVRs hardware (Mainboard Processor clock speeds, RAM, bus speed, Core clock speeds of video processors, voltage etc..)

 

Any input on any embedded stand alone DVR's hardware setup would be appreciated.

That's embedded's greatest selling point... "Who cares - they work!" (Sorry... just couldn't resist - - I'll be interested too in others' "useful" comments).

So whos got the secrets to these because Enquiring minds want to know!!!!

Hmmm, I know GE DVRs use the Nucleus RTOS from Accelerated Technology, and Power PC boards ...

Its a huge array, there are some really crappy PC systems (1 bt878 for 16 cams) and there are really good ones. Same I assume for standalones.

 

 

Alot of them use the same encoders (or knockoffs) if thats what you mean by hardware. The encoder is what is converting the analog cameras signal into a MPEG stream.

an FYI. most of the cheap taiwanese and Chinese embedded Boards/systems are developed in Korea by the same company.

According to Freescale.com (Semi-Conductor manufacturer for Motorola etc.)

Kalatel Calibur DSR-2000e uses the Freescale DSP56F826, a 16Bit Digital Signal Processor for mainboard processing. Dont know exactly how many are on each board of this particular DVR, but here are some specs:

Up to 40 MIPS at 80MHz core frequency

512 × 16-bit words of Program RAM

2K × 16-bit words of Data Flash

4K × 16-bit words of Data RAM

2K × 16-bit words of BootFLASH

Supply Voltage: 3.0–3.6 V 2.25-2.75 V

These are what I like.

It's an apples and oranges comparison. Unless we want to get some EE's in, comparing a MIPS processor to a RISC processor is going to be a waste of time. You can try to compare based on MIPS scores but there is a reason people use the expression "Meaningless Indicator of Processor Speeds". Or FLOPs, or VUPs or bogoMIPS.......

I see that too ... according to Kalatel, which developed the DSR-2000e way before GE Interlogix (which is GE Security now) aquired them, they use Nucleus RTOS with Power PC boards, not sure which Processor they use. Ill check this week, i have one sitting at my parents house.
