HeadsUp

PoF or Power over fibre is coming ..... Has anyone here used the emerging products to run CCTV and power over the same cable ? The advantage is that its immune to EMI / RFI / EMP and can be run through more electrically hazardous industrial environments. Who has used it and which products / manufacturers did you find ?

I have underlined the words that I would like to emphasize to people that read this. If you can decipher the poor english, you would read "Warmly you to test". I presumed this meant they were offering products for me to test first so I would continue purchasing from them. My response and conversation continued with... I dont want to boar everyone to death so Ill leave it there, but the emails continued back and forth while obviously getting more and more lost in translation. I was assumed they were offering me products to test so I would continue purchasing from them. Not only is it impossible for me to remove this post, I never had any intentions to remove this post on their request, as I thought everyone should be warned about their dodgy products. If anything they were trying to bribe me. Its quite funny how Cantonk continue to insist that they CMOS boards didnt have a problem and they just need IR to work at night. Biggest load of crap. I tried to convince them for months that the cameras had an issue, as a last resort I had to dismantle 12 of the cameras and send them back to Cantonk. Finally I got the answer I was looking for from the sales manager. So to sum it up, I was right and they were wrong. The updated boards did show a lot of improvement but they still have they flickering issue just no where near as bad. Also why would a CMOS board have Day & Night setting options in the OSD if it did not have low lux functionality. Image of OSD http://solidgoldsecurity.com.au/wp-content/uploads/cantonk.jpg Here is a few more video examples of their dodgy cameras. Eo06DhzUovk G4iE6eMWrB4 You lost a lot of money due to the problem which obviously was not caused by you or your power supply , if it was me in your situation I would call it a loss just from my labour of around $4-5000. Cantonk should have compensated you , it would have been polite if they had given you a couple of thousand worth of stock which to them would only be a cost of maybe $500. The wording you used sounded like extortion , where really it would have been a clever choice for cantonk to offer products to you as a win - win opportunity for you both. It is typical from Chinese companies however when they sell you something faulty they duck and run or blame someone else , they just didn't learn yet that if they do the correct honest thing it is a great investment in marketing that can give 5 times increase in popularity that improves many more sales

Hi. The problem is there all different formats. Cvi is digital at camera tvi is converted at dvr same as AHD and SDI We have done it with cvi but it's expensive Cheapest way and as most recorders are now full hybrid ....IP CVI TVI AHD SDI ...... Is to use IP over power were needed thanks Tom Yes , The hybrids are attractive for their flexibility. I am sure it wont be long before someone develops devices to do it for AHD / SDI etc but for now i will go with the IP over PLC or throw a few WiFi channels in the mix where cable runs are obstructed.

There are plenty of PLC products in the market now for IP CCTV transmission over power cables , but has anyone seen the same products in a standalone pack for BNC Coax analogue , AHD , TVI or SDI over power cabling ? What is the simplest way to do PLC with analogue cameras ?

Does anyone have a link to compatibility tables for network PTZ cameras with Blue Iris other than their website ? The Blue Iris website does have a list of products and brands but its very incomplete and it mentions in places that PTZ may not work with some cameras. Blue iris offer a trial version but thats not helping me choose which cameras to buy. I would like to get a couple of auto tracking motion detect PTZ domes so they can be programmed to zoom in on anything that moves , auto focus , hold the shot or follow the target for a few seconds and then move back to wide angle shot until the next motion event. I also have vivotek FD8164 , Hikvision DS-2CD1141-I and DS-2CD2142FWD-I cameras to use on the same system. Has anyone used auto tracking PTZ with Blue iris and advise of issues , or advise which PTZ dont work ? Next question , will Blue Iris allow motion detect to work with all brands of camera ? , i have previously tried vivotek FD8164 cameras through a POE switch on to a Hikvision 7616 NVR but found that motion detect and VCA wont work on the NVR despite both devices claiming ONVIF compatibility.

Okay but if you have say 12 cams you still need a 12 port NVR even though you will only be using one port right? Thanks for your help. If you're worried about someone cutting power to your cams have you thought of putting a UPS to give you redundancy for your cameras ? I use a 4500 watt UPS that i picked up at the right price to give backup power to my entire system and i get over 3 hours .

genie 01/07/2017 zzrqz9SQ9 first cam i get these 01/07/2017 qSd9R9r9y9 04/07/2017 Sz9zReQQzQ second cam 04/07/2017 SyzqQeQ9dQ i think what people are doing wrong is they try to use the full serial number from SADP , you must delete the model number from the serial number before you do it.

Yes . true especially considering how cheap HD has become thanks for replying

I have inherited some Pacom PDRH 32 DVR's from a site upgrade. Can anyone advise what they would have cost new and what could i ask for them on ebay ? i didnt see any for sale to get an idea of price. I dont have the passwords for them , so next question is how to break back to default password settings ? thankyou

Hahhahahahahhaha ! Why the *** would you think I wouldn't use conduit ? Ke ? Can you read the question ? I want to know how far apart I should space supports to prevent cable damage. SORRY - missed that bit , but I'm still unsure if you are talking about supporting the conduit or supporting the cable. You are talking about cable damage but as long as the cable is fixed at the bottom where it exits the conduit it becomes self supporting within the conduit. If you are talking about the conduit then there are probably guidlines for your area. I saddle it every metre vertically or at 600mm horizontally Nope I am talking about supporting the cable so the weight of 40+ meters of cable doesn't damage it if it's supported only at the top. 40 meters of cat 6 would be around 3 kg . is it rated to support that much weight without stretching ?

Thank you

Hahhahahahahhaha ! Why the *** would you think I wouldn't use conduit ? Ke ? Can you read the question ? I want to know how far apart I should space supports to prevent cable damage.

if running CAT 6 vertically straight up the side of a building in conduit , how much length can be run without clamping the cable to support its weight ? anyone got figures or standards for this ? I have a 10 story run ( 46 meters )

EMI is the issue I want to avoid , but the customer wants a tidy conduit bundle for aesthetics. Will do more enquiries on cat 7 specs but otherwise it's going 10-12 inches away from the mains cabling.

Both cables would be in their own PVC conduit , they are outside exposed to risk of lightning and salty ocean air so I don't want to use steel conduit. When you say "high voltage" you are referring to the 240 volt AC ? High voltage usually refers to 50,000 volts Sorry pardon my typo , I meant 5000 volts being HV
