  1. How did you control your camera Over voltage and only take out your IR does not sound right Your IR is controlled via the lens controller . This is why I ask how are you controlling the camera Hi again - I do appreciate your questions - when I initially got the camera I wanted to make sure it was a worker - came from an auction site online from a seller of used items. My initial tests involved connecting the SD output direct to a monitor. Turning the lights off in the workshop brought the LED's on - this gave good night vision. After a few seconds the night vision was affected and looking at the two LED's on the camera they went a pale greenish colour then went out. I immedialtely removed the camera from power - put a meter on the power supply and saw just over 16v dc. The camera still switches the internal relay from the LDR being in dark and the camera goes into night vision - B/W - just no IR LED operation. I am currently looking at the monitor for the DVR and the night vision with the external LED array is bloody good (23:30 here local time) .I am counting myself lucky the camera is still working. As mentioned - when testing the voltage arriving at the LED's on the board inside the camera there is 13.8v dc - the whole camera supply voltage - which should be 6v as the two LED's are wanting 3v each - and they are in series. As I am/was using only the SD output (the camera has both - one lead for SD and one for HD) I did not really have any control or access to the smart IR function. There is bound to be an smd voltage reg on the camera board that took a hit and passed the full voltage to the LED's - they both test open circuit. (Taking things apart and testing is something I AM good at;-) ) My comment that I no longer have any control on the smart IR (not that I as able to use) is I am guessing that I will not have any control if I was able to try and access this at a later date - as I have damaged the IR circuits - and the smart control will work only on the IR lLED's in the camera. I'll need to do a read-up on smart IR control and options - when the farm work is over - busy week ahead. From what I have read one can control the way the IR illumination works on close up objects - preventing face white-out - with an AGC feedback system the smart control must use. If I have this wrong do say so. I got thick skin;-) If I am missing something - which is possible - my early work in cctv was 30 years ago and now I am dabbling after a long break -technology has come a huge way - I am more than happy to be educated. My main forte is in elctronics repair/diagnostics and I probably do need to take some time educating myself on the ins and outs of later cctv technology. Your replies are appreciated and if I can add anything else do say so. Fortunately this is not for a customer or such - for use on the rural property I live on - so I have time to go over things. Again, just peeved the damn bench supply I had grabbed to use was one I had got in a bulk buy and had not time/load tested it. Live and learn. Over time I will slowly update the simple system I have here - starting with a suitable HD DVR - more blog/info reading to make the "right" selection. I have an old Pacom 16ch which I got with two other DVR's and a PTZ camera for $100 - so basic system at present - on a fixed low income I have sourced two Pelco PTZ cameras for a great price - and will add when they arrive. Cheers from Rural New Zealand - Land of the Long White Cloud.
  2. If on standard analog then you have no control over the camera IR. You need distance to test smart ir you won’t see it work on a test bench. How are you setting ir distance from camera ? Thanks for the reply. Yes I no longer have any smart IR control on the camera and no control over distance settings. Annoying to say the least. The IR LED's don't function at all so not able to have any smart IR activity. I set the camera up last night covering the back yard with a small standalone 24 IR count outboard illuminator and the picture coming back was surprisingly good with little face white out only when someone was within 5 feet of the camera. To say I am peeved the event happened is putting it lightly and I have taken the suspect power supply out of comission. I don't have an HD DVR by the way. Thanks again for your interest.
  3. I have one of the above cameras and the two onboard IR led's are non-functional - the powersupply the camera was on went over voltage slightly to 16v (was on a test bench "in low light to see led's"and led's were observed to go a slight green tinge - then no operation - colour change like this usually occurs when overvoltage and kills the leds'). The camera still functions fine. I guess I could use an outboard LED panel - but with the camera apart already I'd like to replace the IR LED's. There are plenty avail on aliexpress etc - question is tho - what wattage rating? It is a nice camera with good sharp pics (used on standard def on a analogue dvr) I am guessing 1 - 3 watts.... each ... there are two. Thanks. Update - scotch that .... testing further and it is the onboard cotrol of the LED's that is gone - there is 13.8v dc going to the LED's. The circuitry on the camera board is too delicate to go poking around and I don't have a circuit diagram. The IR/night time switching is still working fine - - so have added an extrenal LED array for the camera. This camera really does have a nice sharp and clear full colour picture - even tho I am using just the SD and not HD output. Excellent night time viewing also.
  4. Anyone care to comment on these two PTZ cameras - a little bit older but I have been offered them at a very good price. One is a Pelco DD427X and one is a Pelco DD423-X Speed Dome. I know they are older but I see they are still for sale on the net new for over 1k per each. Intended use is on a small analouge system using a Pacom PDRH-16-RT DVR. Any comments and or experience with these. Likes/dislikes? Comparisons? Peeves? Thanks!
  5. Hi again - and thanks - thought it must be data - but doesn't hurt to ask - imprinted in my brain cells now When first powering up the camera it does its routine of moving about/initialising, and the screen shows the boot info for the camera and address as 01. If I have changed the address on the camera, during my testing, it shows the new address ( and I had set the same in the DVR). I have set it back to 1 (01) and have the same set in the setup on the DVR. I have tried a different power supply in case it was insufficient - but doubt it is this as the motors run good and strong when initialising. Another reply suggested setting the baud rate to 2400 and not 9600 - still no operation. I'll keep plugging away and will take it out of comission and put it on my workbench with short cable runs and a more than ample dc supply. I'll find a free afternoon and go through the various options in the setup. I guess there is a very small chance something is amiss with the camera. In the back of my head is that I initially had the bi-phase wires reveresed - but I have been reassured this will have not caused any harm. Still it is a small mental niggle Thanks again!
  6. Thanks for the reply - yes I have the camera set correctly - have downloaded the manual for the camera from Bosch - and have tried it on different addresses - all to no avail ...hmmm Have toggled the termination sw601 to see if I had this wrong also. My understanding is that if only one camera this would be set to ON - wheras if there were a number of PTZ cameras daisy chained only the last one on the chain would have this set to on and all the others to off - which sounds logical Mr Spock! I have tried it on the first four channels as one poster suggested. I am wondering if there is something amiss with the ptz side of the DVR ....? Are the control signals voltages or data - as I see no voltage change on the 485 when sending ptz commands - I guess they must be data then .... does anyone have any suggestions for momitoring the 485 output? I am determined to get to the bottom of this bosch ptz now! In the DVR menu for selecting PTZ cameras there is no generic type selection - and the only one for Bosch is Autodome. I did try a dozen or so other makes to see if I could get ANY response from the camera - nahda. I tried all the settings for communication speed and stop bits and parity just out of frustration - but I am sure 9k6, 8 bits and no parity is the correct selection. I could install the camera as a static one - but such a waste if there is a chance of getting it to respond to control. If anyone on the forum has one of these recorders sitting around - a Pacom PDRH16 - can you tell me what voltages you see when measuring across the + and - of the 485 line, as well as from each to chassis ground? Thanks again.
  7. Hi thanks for the reply gadgetmate - cool avatar name! Yes I have set the camera to address 1 and the software is also set to 1. I did spend some time going through about a dozen addresses / mating up each time out of interest - and yes I have the biphase wires connected correct now - I splipped up and had them reversed when I first connected the camera - but when there was no control I powered off right away and checked this - as it was the only thing that I could see I may have erred in. I'll have another look in a day or so. I guess my main question - to anyone who might service these cameras - is if the biphase wires were reveresed and a command given from the sotware - will any voltages sent to the camera damage the internal electronics - I did look for an onboard fuse etc - but just too many IC's to be possibly zapped. Thanks again for your suggestions - good!
  8. Looking for some tips on getting this PTZ camera working - model VEZ-011-HWCS. I am using it with a Pacom DVR which has RS485. I am getting video fine but no PTZ control. The DVR's software has one listing for Bosch - an Autodome - and I have this set to 9600bd, 8 bits, 1 stop bit and no parity - which is the default in the software. Software is set to ID 1 and camera is the same - sw1 on all others off - 9 is on and 0 is off/ biphase switched on..Also sw601/termination set to on - The on-screen controls do not control and function. Now .... I may have made a boo-boo - and hope I have not fried any internals - when first connectiong the biphase wires from the camera to the DVR IU had them reversed ... + and - back to front - for just a moment. Yeah I know .... always check and re-check - have been doing electronics for decades and is my number one rule. I guess the black wire on the camera being + and not - threw me and I may have upset an onbaord IC??? Any comments - apart from what a doofus! I got the camera in a deal for three DVR's and the camera for $100 - so not a lot invested - but would still ike to have the PTZ function working on the camera - rather than just mounting it as it is as a still. Thanks, Graham darn - can admin possibly delete the second of this post - I managed to double post - whooops. also - I see there is a more appropriate forum - cameras - is it possible for me to move this message there? I read that I am only to post to one section at a time - suggestions anyone??
