A DVR system can function without audio recording, but video recording is essential for it to be considered a Digital Video Recorder (DVR).
The BNC video input ports connect analog cameras to the DVR system for recording and management. In PC-based DVR systems, these ports may be integrated into the DVR card or connected via DB25 video cables, as shown in the image above. Similarly, in standalone systems, the BNC ports can be built into the unit's back panel or connected through DB25 video pigtails.
There are reasons for having these two different BNC port configurations:
Built-in Ports:
Durability: Some installers prefer built-in ports due to concerns about durability. Video cables can wear out over time, requiring replacement, which can be costly.
Labeling: Poorly labeled cables can cause confusion if the labels wear off. Re-labeling them may look unprofessional and is often unacceptable, making replacement the best option.
Pigtail-type Ports:
Ease of Replacement: For DVR cards, replacing video cables is easier than removing the entire DVR card to address issues with the BNC ports. Repairing the hardware can leave unnecessary marks on the board, and in the worst case, the unit may need to be returned for warranty service (RMA).
Compact Design: In standalone systems, using video cables makes the units more compact by saving the space that built-in BNC ports would occupy. This results in smaller, lighter units, which reduces shipping costs.
So, which option do you prefer: built-in ports or pigtails?
Connecting an Analog PTZ Camera to the DVR System maybe an easy job for professional CCTV Installers. But for starters, it will take them wild guessing and a lot of trial and errors to accomplish the supposed-to-be-simple task. It might sound weird but it's surprisingly true.
Below is a diagram showing the proper connection of an Analog PTZ Camera to the DVR System:
I hope this will help the starters out there. Asking is a step to Knowledge. Everyone started from nothing. This is something we should not be ashamed of. Be an inquirer!

EMAP support via Remote Client Using an impressive E-Map, you can add floor plans or maps to plot the locations of cameras, sensors and relays. By charting positions this way, the DVR provides you with rapid response-time to emergencies. Via a single click, you can view live display of events instantly.
TV Live Display With TV out function and IR control, you can easily do on site installation setup, configure video quality and perform local monitoring even without network.
Mobile Phone Surveillance Supports mobile phone viewing through wireless devices such as cellular phones, PDAs and other smart phones.
DDNS Support Supports static IP, dynamic IP and dynamic domain name system (DDNS) for easy remote connection.
Multi-Device Streaming Support Supports simultaneous encoding of D1, half D1, CIF, to allow multi-platform web viewing. Each stream is optimized for its purpose and environment, e.g. if you want to view high quality videos for live viewing, you can stream it D1 via PC. On the other hand, if you want to stream videos using lower bandwidth, you can stream it CIF size via web viewing on PC.
Integration Flexibility Can easily be integrated with other systems such as Hybrid DVR, Video Server, CMS solutions and Sensors/Alarms.

We've recently seen and heard from the news some astonishing and heart-breaking real-life dramas caught by CCTV. They may look like scenes from a movie but they're actually real - no scripts, no directors and no stuntmen.
Here are 2 of the most sensational and controversial CCTV footages that lately created wild buzz esp. over the internet worlwide.
A Robber's Change of Heart:
A repentant robber fell to his knees and prayed with the clerk of the store during a hold-up, according to US media Wednesday, which said the man nevertheless proceeded to pinch 20 dollars from the cash register.
The 23-year-old initially entered the check-cashing establishment in the midwestern city of Indianapolis, Indiana seeking a loan but left, purportedly to get an identification card that was requested, law enforcement officials told ABC television.
He returned armed with a gun, which he pointed at the employee, telling her that he had a son to feed and "no choice" but to revert to robbery since "times are hard," according to the report of the heist.
But when the clerk started to talk to the man about God, the gunman appeared to have a change of heart, confiding in the clerk about his hardships and asking her to pray with him.
"I started crying and praying and telling him, 'Don't do this,' he was too young to throw away his life," store clerk Angela Montez later told a police dispatcher by phone.
"He took the bullet out of the gun and said, 'Here, I'm not going to hurt you, I'm not going to hurt you,'" Montez said.
The suspect, Gregory Smith, asked Montez for a hug and asked her not to report the crime, then told her to go into the store's restroom and not come out for 20 minutes, police told ABC.
Officials said Smith took Montez's cell phone from her purse and 20 dollars from the cash drawer, leaving the rest of the money behind.
He was arrested on robbery and firearm charges when he turned himself in to authorities a few hours later.
Baby Miraculously Survived Pram's collision with Train:
A six-month-old baby boy whose pram rolled onto railway tracks in front of an oncoming train has survived with only a bump to the head, officials said Friday.
The child, who was strapped into his stroller when the accident occurred, was dragged about 35 metres (yards) by the train as it pulled into Ashburton station in Melbourne's east on Thursday afternoon.
"The pram rolled a very short distance straight over the edge of the platform and onto the tracks right as the train was coming in," Connex trains spokesman John Rees told AFP.
"The baby has gotten away with just a cut on the forehead."
Rees said the driver slammed on the brakes as hard as possible as soon as he saw the pram tumble in front of him, and was aided by the fact that the train was slowing down as it entered the station.
Paramedics, who arrived to find the baby being comforted by his mother, confirmed the child received a bump on his head.
"Luckily he was strapped into his pram at the time, which probably saved his life," paramedic Jon Wright said in a statement.
The accident occurred one day after Connex issued a child safety awareness campaign focusing on warning parents to keep infants strapped into their prams at all times while on train platforms.
How did you find the above sample CCTV footage? It was an accident caught in CCTV camera. Please forgive me but I must admit that I found it very funny at first view. That's the least that I can think of to happen to the waitress in that set up (actually giggling while writing this). It's shockingly entertaining. Kudos to her for getting a tight hold on that tray (LOL).
But seriously, we may find CCTV footages in these kinds of scenarios very useful. It's an honest evidence to probe unwanted incidents in the workplace. In that video, it appeared very clear that it's an accident. Using the recorded videos, authorities will be able to examine the event, identify causes and execute corrective actions and necessary sanctions to responsible personnels. I actually worried for the lady afterwards. I wondered if she's okay. Moreover, I can only hope that their pub is not situated in the 2nd or 3rd floor of a building.
This is another CCTV footage I found interesting. Amazing how the fugitive survived that death-defying crash and still managed to get on his feet and run for his life. But I doubt if he managed to get away from the police. A real-time CCTV video is a very useful lead to help the authorities locate, chase and corner escaping criminals.
We may find a CCTV footage funny, shocking and amazing in a sense. But nevertheless, it still gets to serve it's significance and very purpose; that is to provide a material that will lead to solving crimes and identifying anomalies in a workplace... to apparently establish better operations and procedures.
The CCTV and Video Surveillance Market wasn't spared from the massive stroke of the Global Economic Downfall. Not all but most of the larger CCTV Companies around the globe were hardly hit by this unwelcome phenomenon. But as we all know, there's always a rainbow after the storm and the storm that devastated our industry is about the come to an end. There's a striking future ahead of the CCTV and Video Surveillance Market. A very big opportunity awaits.....
The video surveillance market is showing limited unit growth in 2009, but still seeing revenue declines as the weak economy takes its toll. However, the impact is greater in some segments than others, according to market research firm, In-Stat(http://www.in-stat.com). Due to their higher cost, IP cameras will see a large slowdown in 2009 shipment growth. As the Networked Video Recorder (NVR) segment is tied to IP camera shipments that area will be impacted as well.
Meanwhile, stimulus programs are actually increasing surveillance equipment shipments in select applications. "In-Stat sees Digital Video Recorder (DVR) channel shipments growing faster than camera shipments, with hybrid DVRs that can connect to both analog and IP cameras increasing at the highest rate,"says Michelle Abraham, In-Stat analyst. "We expect the overall market to return to growth in 2010."
Recent research by In-Stat found:
* After a decline in 2009, revenue from analog cameras, IP cameras, DVR/NVR, and IP encoders will grow to US$19 billion in 2011. * Video encoding for DVRs, IP cameras, and IP encoders is moving to H.264 fromMPEG-4 part 2. This is enabled by more powerful ICs able to encode multiple streams of H.264 on a single IC. * As pricing comes down, the attach rate for video analytics in videosurveillance equipment will increase at a fast pace. * Semiconductor revenue for the video surveillance equipment will be stablethrough 2013, with lower average selling prices offsetting shipment growth.
