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

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 )

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.

Can someone confirm the correct minimum spacing between CAT5e and 240 volts AC cable ? My clients electrician claims they can run together without interference .... I have to run 40 meters ( 131 feet ) and it will run parallel with 240 VAC over that whole distance. The CAT5 will be carrying 2 analogue cameras over 2 twisted pair with 24 Volts AC on two pair using 24 AWG The cameras are 250 watt ( No IR ) , my calculator gives 3 v voltage drop ? What separation between cables ? ps , if i use CAT 7 instead of CAT5, how much difference will that make to spacing with its claimed improved shielding ?

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

I am evaluating an upgrade on a large site. The existing contractor "has left" after charging the client upwards of $ 1200 fitted for $ 35 analogue cameras of around incredible 380 TVL resolution. The site has 5 buildings spread over 40,000 square meters. There is already RG59 coax through most buildings for the existing analogue cameras , and underground conduit with spare CAT 5/6 between buildings and the head office building on the same site. My initial thoughts are to use between 5 to 8 1080P AHD varifocal cameras with IR per building . What are peoples thoughts on using a single 8 channel DVR in each building , then using CAT5 LAN connection from the DVR in each building to a main NVR in the security room ? the DVR would be dual stream capable to record locally simultaneously while giving 100% streaming to the NVR just trying to get the best image quality for the money. If we used IP cameras in every building then the cameras are a little more expensive and we dont get redundant storage capacity in each building . My thoughts for not going single NVR with a router in each building is that if our main NVR goes down then we have no video backup anywhere , whereas if we have individual DVR and storage in each building , we might lose the NVR or one DVR on reliability but we are likely to still retain 80 % of the system as active. Can this work ? , who can blow holes in it with something better ? thankyou

I am looking for the smallest router possible to match up to this 4 channel NVR pictured below It will be vehicle mounted and must be 12 Volt DC powered also need a very small 12 VDC converter to power a eSATA hard drive . anyone found a compact "regulated" converter to run HDD off a vehicle 12- 13 volt supply ? any suggestions ? thankyou kindly

Yeah SSD are getting bigger and cheaper but I would like at least 3 terabyte for 4 cameras 4 x 1080 P cameras could use up to 320 meg per day in continuous driving I currently have a 1 terabyte 2.5" laptop spec HDD recording from four analogue cams and have it mounted on rubber cushion mounts , its surviving overland four wheel drive in harsh terrain so far but I am looking forwards to the day in 1 - 2 years when we can hopefully get a 2 TB SSD for under $500 , they are currently $2500 each here.

anyone got ideas on the best way to set up 4 x 1080 P cameras in a vehicle with a compact DVR / NVR that will power up fast and record on to large capacity HDD ?

thanks , but i need 4 - 5 port router

I found a few options for the power supply for the SATA HDD http://au.rs-online.com/web/p/isolated-dc-dc-converters/7256409/ http://au.rs-online.com/web/p/isolated-dc-dc-converters/7962135/?searchTerm=7962135&relevancy-data=636F3D3126696E3D4931384E525353746F636B4E756D6265724D504E266C753D656E266D6D3D6D61746368616C6C26706D3D5E5C647B367D247C5E5C647B377D247C5E5C647B31307D2426706F3D313426736E3D592673743D52535F53544F434B5F4E554D4245522677633D4E4F4E45267573743D3739363231333526 or maybe trim down one of these 180W DC 12V ATX Power Supply Car Auto MINI ITX PC Pico ITX switch PSU nobody got suggestions for a miniature 4 port router to suit vehicle mount ?

Can anyone look at my port settings and tell me if they look right ? , i cant get remote view from other computers. I used the DNSClient i found on the V8.13 software (we dont actually have to pay for a domain name / static IP address from DYNDNS.com any more.) Geovision DNSclient gives me an IP address (public IP ) but the IP address i use in my router port forwarding settings is the one i would use to log in to the router right ? i pinged the IP address given by the DNSclient and it is active , if i type it into a browser it takes me to the router page and asks for the router login name and password but thats as far as i get. i tested the DNSClient IP and every port at www.canyouseeme.org but it says no ports can be seen what am i doing wrong ?...... i have wasted about 14 hours watching youtube videos and fiddling with settings to try and resolve this. the port settings i am using above came from the http://www.portforward.com website , where they give port forward settings to suit Geovision cards The router is a Billion 7800N. i could install V8.5 software ( compatible with Android smart phones and GV-AView android smart phone app ) but the reports are not that great from what i have seen so far so i will try to get center V2 working just with version V8.12 first

Hi people i have spoken to a few manufacturers about obtaining LPR camera modules and i have a feeling that the same base CCD modules and board is used for both LPR use and standard day/night CCD's obviously there will be different settings used in WDR settings to cancel out headlight flaring can anyone confirm this or are there too many models covering a wide scope of applications between manufacturers ? opinions please ?? note : i am not including ANPR cameras in the above statement , just basic LPR CCD's

I have a GV 1240 which is not restarting the application after the computer reboots In configuration settings i have the box ticked for " auto login on restart " but it has ceased to auto login after i powered down the CCTV computer and connected a different UPS to the system. I tried removing the UPS and going back to mains power but the issue still exists. It was working fine before this . all other functions are still working anyone got suggestions of what to check before i reinstall the GV 1240 software as my first attempt to resolve the problem ? hoping its not a hardware issue with the DVR card
