The IP recording and management system is a crucial part of your IP camera system. If you select the wrong solution, you could find yourself without the critical video evidence you need when an incident occurs, or worse still, your security could be breached, and safety threatened because your surveillance system didn’t provide an alarm.
We compared several video recording solutions. The best video recording and management system depends on your objectives. There are two types of recording systems for IP camera systems to consider. Each one provides some unique capability.
An old man read in the paper one of his friends had been arrested for tax evasion and decided to write him a letter. He wrote that it was planting season again, but he didn’t have enough help to sow his fields this year.
The following morning a dozen law enforcement officers completely tilled the old man’s garden without an explanation. Later the mail arrived with a letter from his jailed friend which said “DO NOT DIG UP THE GARDEN WHERE I HID ALL THE CASH. It’s the best I can do from here.”
Pan tilt zoom (PTZ) IP cameras connect to the network and provide the ability to view extensive areas. A PTZ camera can move back and forth (pan), up and down (tilt), and zoom in and out. When it is combined with intelligent video management software (VMS), it provides an effective surveillance system.
This article compares several PTZ cameras. We considered several characteristics, such as the zoom lens, camera resolution, low light sensitivity, pan, tilt ability, and nighttime viewing capability. This comparison should help you select the right PTZ camera. Remember that the most critical question is to determine if the PTZ camera meets your objectives.
Access control is anything that is used to prevent the wrong people from gaining access to your secure area. A door lock and key control access. If you have a dog in your yard, with a big sign that says, “Beware of Dog!” You have access control. Access control always includes a key to allow entry. The dog only lets in the people it knows, so that’s the key.
Door access control systems use various credentialsto unlock the door. Credentials can include physical cards that we carry, a PIN number we enter, or even the physical aspect of a person (biometrics such as fingerprint or facial recognition). This article compares the credentials that we carry. They are sometimes called keycards, prox cards, or smartcards.
What is the best IP paging system? There are several configurations and implementations that can be used depending on your requirements. In general, the PA over IP system is much easier to install than the older central paging amplifier systems.
Instead of running wires from a central amplifier location, the IP paging systems use the network infrastructure that’s already in place. There is a choice of PoE powered speakers that attach to your network or small network-attached amplifiers that drive multiple speakers.
This article compares two types of implementation: the powered IP speakers, and the IP amplifiers with multiple attached speakers.
A fifteen-year-old boy came home with a Porsche, and his parents began to yell and scream, “Where did you get that car?!”
He calmly told them, “I bought it today.”
“With what money?” demanded his parents. “We know darn well what a Porsche costs.”
“Well,” said the boy, “this one cost me fifteen dollars.”
So the parents began to yell even louder. “Who would sell a car like that for fifteen dollars?!? And to a kid?!?” they asked.
“It was the lady up the street,” said the boy. “I don’t know her name – they just moved in. She saw me ride past on my bike and asked me if I wanted to buy a Porsche for fifteen dollars.”
“Oh my goodness,” moaned the mother, “she must be a child abuser. Who knows what she will do next? John, you go right up there and see what’s going on!”
Explosion-Proof Cameras, High-Temperature Viewing, and Other Enclosures for Extreme Environments
Unfortunately, the need for special equipment is only discovered after the first disaster. When electric power was first used in coal mines, the lethal explosions prompted the changes in the electrical engineering standards. It became apparent that sparks had to be prevented when there was coal dust or methane gas present.
How do you prevent an explosion? What camera can you use on an oil rig or in a coal mine where the gases or dust could cause an explosion? How about a camera that can view the scorching gases of a rocket launching into outer space? These are not your standard CCTV surveillance cameras. Special explosion-proof enclosures are required.
The explosion-proof and other extreme environment cameras systems include special enclosures that protect the IP camera. This article reviews how industrial IP camera systems are protected in extreme environments.
