15 m should work normaly. For better results you can use twisted pair converters.

.... or SAT TV, not video cable.

If that camera support PelcoD, write me Email spavilionis@fima.lt, and i can sent foryou PelcoD protocol.

About video analyse on a chip... http://www.objectvideo.com/ I so that at IPSEC. Its truly work good.

EIA is the same, like NTSC, but without colors.....

Maybe, you can find useful information about network design for networked CCTV there: http://www.axis.com/solutions/system/index.htm

Playback is the same, like live video. System records 25 fps each camera, then, after specified time, reduces it to 2 fps automaticaly. Just turn back playback JOG/Shutle ring on Joystick cotroler. Reverse playback starts instantly. Playbazk speed depends on ring turning angle.

Look there: http://www.cctvforum.com/viewtopic.php?t=5370

On Site, you can use tinted glass, to close lens Ireis, then small service monitor, like this: http://www.pelco.com/products/default.aspx?id=466 Of course, rory way is better: setup cameras in your office, previously you should find correct view angles with view finder.

One of solutions: http://www.boschsecurity.com/ipnetworkvideo/en/start/index.htm you can use encoders on each camera, record MPEG streams, and get second stream via decoders to the analog coax. Or Axis: http://www.axis.com/products/video/about_networkvideo/index.htm

I have problem. I should explain some of CCTV basic principles to student. But, i'm not a techer, and i don't have time for teaching. Maybe, somebody know some useful links?

And dont forget about shuter speed. When peapole moves, better use shuter speed about 1/100 1/250. You can use flickerless mode on camera, manual shuter. High end Bosh camers have function "Default shutter" It means, camera hold defined shutter speed as long, as it possible. First use AGC, then- slower shutter speed. Nice function.

Now it 20 Spectra domes, 2 domes per location. Future expansion up to about 100 locations. Maybe, no maps.... Not finished software. Not all functions work. Not work on slow networks. Still waiting new SW version... Now i use 5 Worstations WS5050 with KBD5000 and decoders. VCD officialy relased month ago, and we will use this part after 2 weeks. Abaout instalation. It is a power distribution stations around our country. At ech small station are 2 Domes and encoders. 5 viewing locations in different cities. 2 recording centers. Benefits: Good qulity. Real time recording. Small latency. Instant playback. With Spectra domes- 10 alarm inputs per encoder (7 on dome, 3 on encider)

Now i"m finshing project with Pelco Endura. It looks nice. Of course, FIRST you should design good network with layer 3 managed swithes. Any questions?

Cool. Thanks

There are many solutions. For exaple, you canuse Pelco Esprit Pan/Tilt with PelcoNet300 encoder. www.pelco.com

Hi, I found some: http://www.sennetech.net/ Maybe, that can be useful for us..

Hi, I found something. Maybe that helps for all: http://www.sennetech.net/

It is one problem witg Syac- it's like a one chanell server with quad. Of course, it is possible swithing between cameras. About PTZ, i found that about VCL protocol support: VCLTP x VC8MS-ORBM/TP Orbiter Microsphere

Bosh has autodomes with autotrack. And any network sever

RS422 work with philips biphase, but it is not the same. You can buy LTC 8786 RS232- Bi-phase converter from Philips/Bosh.

Main GV problems- choosing good PC. Oll other parameters are better than Intellex. Exept, thet for remote live vewing and remote playback shall be use different programs.

Bosh have very good cameras. Flexible matrix systems. DVR's i dont like. Very good public address and conference systems. Support is bad (mayby in our country)

Pelco use Coaxitron protocol. No control cables. Dome control is transmitting over same video cable to dome. But RG58 cable is 50oms. You must use RG 59 cable. Server not neccesary.

Mayby Pelco DX8000 series helps you http://www.pelco.com/products/controlsite/videorecorders/digitalvideo.aspx
