I'm on firmware 5.3.8 Did anyone of you has 'preset freezing' function working when patrolling between presets? I set patrolling function between some presets and I'm using 'Preset freezing' option. Actually the patrolling function is not applying 'preset freezing' moving from one preset to the other. This is quite an issue to me as without it, with slow connections, I'm loosing frames in zooming actions. Anybody of you is aware of this issue and maybe has a solution? Maybe it works but is not compatible with some complementary setting I used hence if anybody of you has success with it please share. Did any of you has 'preset freezing' working with other Hikvision's PTZ? Furthermore I'd like to use 'motion detection' for recording just the relevant 'motion episodes' of the single preset with the PTZ still 'patrolling' between presets. Is there a way to obtain this or the continuously changing view prevents it? Thanks in advance for any contribution!

I already thanked you aruegger. I already joined theyr forum and they are helpful, but my problem is not yet solved. So keeping alive both posts fishing for a solution. Will update the other with the solution as soon as I find it on one of the two. Hope I'm not breaking any netiquette with this!

UTP wiring are correct, apart that I used dedicated wiring for 24V (not UTP) About GV-net I already checked it using instead an optoisolated RS232 to rs 485 card grounding it. Actually the problem is still there! Additional clue! With the optoisolated card I get an additional 'issue': from off state server doesn't want to boot until I unplug the dedicated power adaptor of the optoisolated card. Once unplugged the system boot and I can plug it back!

I'm using cat-5 UTP with UTP-111VL from Hesavision. It walks on the roof far from any power line. I'm gonna check with tensions...

Thanks for the advice, ill come back on this forum with the findings... Just an update: Changed the back-box with no result (problem same as before so reinstalled the old back-box). Discovered that the wandering happens with the video filtert installed. Without the filter I only have sparks on each ptz command, but actually ptz commands are always precise and correct (no wandering since yesterday). To sum-up: - No filter on Pelco spectra III video -> sparks on each rs485 PTZ command - Filter on Pelco spectra III video -> after few PTZ commands camera start wandering, doing strange things up to resetting/restarting... ???? Anything to do with coaxitron command?

Installation is on the top of the roof! What about a 'mild' lightning (?) that hit chirurgically the backbox and Spectra III yet saving all of the other (many) electric devices connected? The Spectra IV is not available anymore. Will check the backbox this week, earlyt next week at least to exclude it. If the problem remains I'll service again the Spectra III I'll keep updated on the findings

Thanks Survetch for the reply! Isn't it possible any damage in the active part of the backbox? (Looking around it seems that backbox has some circuit inside). My installer was oriented in changing it ... Thanks for your advice. I'll ask the installer to take with them also the Spectra IV in case the problem were not resolved just changing the blackbox!

First some warnings: Long story ahead! (even if kept short) Beginner ahead! Poor English! I’m experiencing a strange problem with my Pelco Spectra III se driven by a Geovision GV1120 card. Driving the dome (It happens both from the DVR and from remote) I experience that after some commands the dome start wondering around, change focus/iris and then make crazy things like ‘recording pattern’? ‘downloading bios’? ‘reboot’ … It’s a while I’m after this and here is the full story. End of Last year added a Pelco Spectra III se (used) to my home dvr system based on geovision (reliably running since 2006). Installation was 60 feet from the server running the DVR and telemetry was given with the GV-Net geovision card (rs-232 to rs-485) Everything worked fine (patterns were driven from geovision card). The only issue I had was that I needed to switch down to 2400 baud as with higher rates the dome was loosing alignment of the preset sent from the dvr after some running time. This summer I started experiencing problems on the video. On the hottest time of the day white stripes (I could describe it as washed out white zone with noise on the perimeter) started appearing up to the point that the DVR sometimes for short period loosed video connections to the dome (video lost). This problem never occurred in the night and was not related to movements of the dome (started also on static views). I serviced the camera. In the mean time I’d been given a Spectra IV. I set it up and run great through the Summer (with patterns and preset) with no issue also in the hottest days (this appeared to me a confirmation about problem being not with the backbox but with the Spectra III as backbox has not been changed). Early October my Spectra III came back, no repair made, it seems for convenience It has been substituted with a new one (urrah!). Now all the weird things started to happen. After plugging in the new unit and reinstalled the old driver, I noticed some noise in the video, actually different from the old one I experienced. This time it happened only on rs-485 commands. It was not white washed and it was more like ‘static’ starting from the upper/lower part of the screen right the moment the command was given. Keeping the camera in motion with commands from the DVR the noise could raise giving a ‘video lost’ message which then stops after stopping sending commands. Puzzled, if it was a problem with the new unit, after some checking I disconnected telemetry from the GV-net and used telemetry from the Standalone battery powered monitor of my installer keeping the video connected to the geovision DVR and the problem completely disappeared. I ended up considering the new unit could be OK, but I just had some grounding problem (?). Substituted the GV-Net with a Roline converter RS232-RS485 with galvanic isolation and grounded it to the same power circuitry of the dome. Checked again, but the problem was still there! Added a video RFI filter before the DVR and noise problem on RS485 command was gone (actually to isolate the problem I installed back the old gv-net and actually problem didn’t arise back, so it was video line related (?)) Spectra III worked flawlessly for some hours (recorded presets and started patterns) then it started going crazy. The problem now I’m facing is the dome's ‘walk about’ problem described at the beginning (thanks for the patience in reading all of this!) Now I don’t know what to do: 1) Service again the Serie III? (it worked with telemetry from the standalone monitor, but maybe the device was better isolated and I didn’t stressed it enough to trigger the ‘walk about’ problem) 2) Service the BackBox? (Actually worked with the Serie IV. Maybe Serie IV is more solid and less prone to this problems than Serie III) 3) Concentrate on groundloop problem? (Serie IV has less issues regarding ground problems???… ) 4) Other smart suggestions… actual dome version: Spectra III SE Version: 1.34 BIOS: 1.12 Camera Module Model: DD59C22-X Following a list of what I already checked with no results: - The dome is under UPS, changed it and powered directly from main - Switched off ‘proportional panning’ and ‘autoflip’ - Checked all of the contacts/wires - Removed and reinserted Dome into Backbox several times - Comm configuration 2400 8 N 1 (none) - Checked on this forum for similar problems On it’s own pattern the Serie III can go on forever fine, the problem is with commands from RS485!
