anyway it is starting to fail with dropouts. it never did that before i had the fire. so it is either getting old or got some damage.  i'm looking for another nvr/dvr hybrid unit but when i go to ebay and ask the sellers it seems no one has a clue.

so does anyone happen to know what brands now will let you see all the cams on one monitor as i'm now doing.  i did get 2 new dvr units and one showed 16 bnc spaces and 4 ip spaces and the other one showed either 16 bnc spaces or 8 ip spaces.   i need 16 spaces and i need all the cams to show.

the one i'm using is the westshine hybrid and i have an xvim 8ch but that will show 8 bnc and 4 ip cams.  i ask the sellers about this and they have no clue. so maybe some here have a hybrid that can see 8 bnc and 8 ip cams on the same monitor  

I tried to remove CMOS battery but it didn't work.

How to reset password or flash firmware? Thanks

Model: no

Brand: no :(

DVR Analog 4 channels

My DVR, I have a Lorex lh118000. Dhcp to static, media port is 9090 web port is 37777. Netmask 255.255.255.000 gateway 192.168.1. DNS1 is 0 DNS 2 is 0. auto port forwarding enabled. Then there is a setting that says mobile username = admin, password 12345678, mobile port 1025.

I had a spectrum router internet service provider is spectrum couldn't get it to work on there, so I changed my router and I still can't get it to work I have tried different ports. The default gateway and IP addresses I have verified match both the router and the DVR.

I can't get the view on my PC or my phone

I attach a picture showing the camera and fault. 2nd block down and 2nd in (i.e. middle block)

The faulty picture shows on all good connections, accordingly it is the camera not the wiring to that camera.

BTW the camera was given to me a couple of days ago, I was also given a second same  specification camera and that works excellently.

I have tried all camera types available to my DVR i.e. TVI, CVI AHD and auto for this faulty camera; the good one works on auto & AHD

Is this bottom band problem a known fault or is it simply a faulty piece of electronics that should be thrown away.

I am new to CCTV setup and operations. My daughter is wanting to put some cameras up around the property to watch the wildlife and feral cat's.

I was looking at getting her a couple Pelco camera's and housings. There is ton's of surplus Pelco for sale but I have a couple questions on the setup of the system.

1) On the  Pelco EH3512-2 camera housing which is the 24v housing will that housing and camera have 2 separate 24v feeds? 1 for the heater and fan and 1 for the camera? Will be feeding cameras from Pelco MCS16-20 power supply. Just trying to get idea of how much conduit I need along with RG59 with power feed and if I need separate run for the housing.

2) Will the Pelco DVR DX8100,4500 work for her recording?

3) Using the Pelco CC3701H-2 cameras.

Thanks

my DVR type is a HD-Vision and has 3 outputs; VGA, HDMI and V-out (BNC)

I appreciate help with the following;

the HDMI is not working when connected top a TV or monitor and I do not know when, any help would be highly appreciated.

when I connect V-out(BNC) via normal TV Cable from the DRV to my TV I get no signal , I do not know why?

No signal is getting through to the monitor

It used to work

Cable has been up 10+ years

Have tried various modalities like cleaning contacts

Latterly have disconnected both ends of the video cable - then joined the earth braid and live together at one end

Went to the other end and used an ohms meter to check the reading over approx 280m  (2x140m) - by one probe on the signal centre and another probe on the earth braid- it was 15 ohms

Now, is that what you would expect over that run of cable ?

Thanks

I have a samsung sch-750 analog camera that I would like to control from a PC. The manual is not very clear on what protocol the camera is using. Also, it kind of contradict itself about if its using rs-485 or rs-232. I've joined some screenshot attachments from the manual.

The manual specify the RS-485 configuration(parity,data bit ect...) and then remote pinout seems to be for rs232 because of the TX and RX(see first image). RS-485 pinout is usually a+ b- not TX RX.

To had to the confusion, in the specs , it say : RS-232C -> Built-in(see second image). Lastly, they provide a table with different command without specifying the protocol(see third image). I've checked on the web and does not look like pelco-D protocol.

So my questions are:

-Should I connect the camera to a rs-232 or rs-485  usb dongle?

-Could tell me what protocol is being used (pelco-D , pelco-P ect...) if you recognize it?

Thanks for your help.

I have a problem with a 16CH HD SDI DVR from the Eyeview brand model HID1608HL, it turns out that I bought it on the street without abiding by the problem it brought, since for the configuration I clearly needed a password that I do not have and researching all over the internet I find that It is a Chinese brand that is not seen much and when reviewing the Eyeview page this model seems as if it were discontinued because it does not have any type of manual and I cannot find information anywhere to be able to delete the ADMIN password that it asks for. I have tried with all the possible keys, with DVR key generators with the date, I have removed the battery and changed it for a new one giving it a period of 2 hours without the battery, and it continues with the password and I don't longer know what more I can do please if someone can help me with this thank you very much.

Thank you for your help.

I can get it to send emails and so I know its connected and i have the port forwarded but I can't sign in from my computer and view system with local IP number (or my main IP number followed by the open port). On a Mac and on Safari it just keeps telling me to install plug in.   On an old windows 7 internet explore 11  I have followed the directions about trusting the site and checked off all the activeX control's but never get past a dark blue screen (no prompt to download activeX).

NOR (what I really want) is to view from my iPhone.  I have tried several apps plugging in the IP numbers, and password but can't get connected.  The instructions I found online are very vague but say it can be connected via iPhone.

The one camera (not original to the system) has a 4 way button and only works on analog so I assume this is an analog system.

I don't have the original remote it would have came with - any chance someone knows a remote code to program and use a universal remote??

any and all help is appreciated!

I'm trying to update an Hikvision DS-7204HVI-S DVR and I don't know if the recorder is compatible with DS-7204HVI-SV/ST version firmware... Since I don't want to risk it before I have confirmed firmware for this model, does anyone has an old backup for this recorder...?

Or do you know if it's possible to make a dump of the current firmware?

thanks

  Hello and thanks for the help in advance.

    We have some older Panasonic CCTV controllers (WJ-HD616) that still run and have no plans on removing them for a while. With the removing of IE 11 to happen in Jan 2023, we will have no access to view through web browser. We do have a central location that has a full install of Panasonic security CCTV camera software so we are not dead in the water, but it is for management that access the controllers every once in a while through web that needs to be addressed. The cost for the Panasonic software is expensive a few thousand $ per install. Looking to see if there is any alternative, if someone has success for web browsing (Opera / firefox), I have tested but not done successfully as of yet..... Or if there is a software that is cheap that we can purchase and install.

      Any help would be great, 

        Thanks so much!  

We are retrofitting an old analog CCTV system and we have noticed that the cameras that are farther away look really bad... ghosting and double vision, etc. The longest runs are around 250' there are no problems with cameras that are closer to the DVR (like 175') … Are there any know distance limitations? The manufacturer has not been much help. The new cameras are 12vdc 5mp... connectors are good... solid core copper braided RG59 cable.
