Maybe you tried flashing an English firmware. These don't work at all by design. But the flashing process should work properly nevertheless. Maybe you don't have the latest hiktools or something.

The name (ci) doesn't matter. Its the UID/GID that count. Check files with 'ls -n'. Should be 1000/1000 if i remember correctly.

In v5.3.0 its similar (just tested the CN version so far). Don't know if its working as the integrity checks are still in place that reboot the camera.

@litch: Thanks for the 5.3.0 language fix. Works great! There are some bugs in your tutorial though: These are the ones i can remember. No guarantee. Edit: CRC32 I have reverted the ash fix. My camera is rebooting every 10mins or so with it. What are the restrictions of psh exactly anyhow? The SSH shell seems to be busybox/bash on my device even though psh is started as one of the earlier processes.

I've done this to see the difference between composite and s-video signal to be prepared what i could expect from a camera with both outputs. The problem was.. the camera i got had such a bad chrominance channel that those s-video improvements weren't important at all. So, here are some synthetical testimages (PC/Loopback capture) from full resolution PAL signal with high per-pixel information (576 TVL) captured at 704x576 (52µs per line) from tv-out (unprocessed/pixel-exact/no flickerfilter). Hardware is: Ati R300 TV-Out Philips SAA7134 based capture card Maybe its useful for someone... Note: The pictures below have nothing to do with a real camera picture. They are created by a PC and re-captured over analog signal to simulate the signal loss of composite and Y/C only. Left side is composite, right side is s-video (in both pics). The pictures may be scaled down to fit screen. Click on the scaled pic to get pixel-exact view.

I tried cat5 (awg26) but somehow the picture is heavily skewed and too dark. You can't notice anything but differences in brightness if you point the camera to dark or bright places. Cablelenght is about 5m (16ft.). I had to assemble the cable myself since it is a custom 8pin > 4pin mini-din connection. Does it need some extras termination or something? Anything wrong with awg26? Edit: Ok.. forget it. Luma and chroma was swapped due to horrible article at wikipedia. Talk about male jacks and show female schematics.

Hi, is it possible to get a stable long-range s-video connection (50-80m)? I have a s-video camera and if possible i would use that output instead of composite/BNC. There are up to 20m retail cables (75ohm) available (for home cinema) but its not recommended to use cables longer than 10m (by wikipedia-de). They say luma and chroma will interfere and negative impact on signal runtime will occur or sth... Whatsoever... is there maybe a trick to achieve larger distances? Twisted-pair or something?

And you didn't use baluns? How long was your RG59 cable?

Y/C has slightly higher bandwidth for luminance and removes the typical 'dot crawl' effect of composite signal. The camera has OSD. The difference should be visible there. Maybe even only there... I can post some screenshots once the camera arrives. I just know little about baluns. Full name is Balancer/Unbalancer and there are active and passive ones. My current understanding of baluns is... one signal (line) will be adapted to twisted-pair (2 lines) via balancer and adapted back at the end with the unbalancer. Is this correct? What is the approx. price for such baluns? And which ones do i exactly need? I found so many different ones, labeled 1:1 or 1:9 for examples. Not sure if this are even the right ones... RG59 cable correct? Y/C has 4pins... luma, chroma and 2*gnd. Do i have to "pair" all lines with baluns so i need 8 cables and 8 baluns?

Hallo, i'll get a 'TOPICA TP-2000DS' camera with 8pin mini DIN control port. I'm wondering how it is meant to be done controlling the camera with that port. I also want to use the S-Video signal (Y/C) with short cable lengths (<10m). I didn't find any information about that 'control port'. So, either it is proprietary or that trivial it is not even mentioned anywhere. The only informations i found are in the pic below (taken from manual). I could assemble a custom Y/C cable (8pin->4pin s-video) myself but would prefer to get a retail one with additional RS232 (if available). Depends on the 'RS232' functionality i would gain. The camera has OSD (on-screen display) and 'auto iris' capabilites. My guess is, one can control 'zoom' and maybe even the complete menus with OSD by remote. I don't know... So, does anyone have some informations about that control port and how it is meant to be connected (to the pc) and what software is needed? Are there any retail cables available with s-video and RS232 for that port? camera specs: wwwxtopicaxcomxtw/1/products-detail-spec.jsp?product_id=7 8port mini DIN on camera: wwwximagebananaxcom/view/9lwaz44b/topica8pin.png (sorry for the links - forum anti spam - replace 'x' with dots)

Hallo, found this forum with google by coincidence. I'm trying to get some more informations for my cctv camera. regards
