When thinking of a security camera, there are a few core essential traits that immediately come to mind when we picture a “perfect” security camera. The perfect camera must be durable, discrete, affordable, and of course, functioning as a surveillance unit and monitoring specific areas while recording data. In my opinion, the type of camera that meets all the needs of a perfect camera is of course the Bullet Camera. And here is why.

1. There are several models of bullet cameras that come with a high durability rating and have been designed for outdoor use. When looking for how “durable” a camera is look for their IP (Ingress Protection) rating which will tell how suitable a camera is for outdoor use. When models fail to list this detail look for the description of a camera as “Waterproof”, “Weatherproof”, or “Outdoor” as an indicator of how durable it truly is.

2. IR Bullet IP Camera are by conventional standards small. While there are a few that come in large sizes a truly perfect bullet camera must not be big and lack of size is a very good thing. Small bullet cameras are hard to spot by intruders, easy to mount and install, and provide all the functions of a standard security camera.

“With all the DVRs on the market, why not just buy the cheapest thing I can find. They are all the same right?- That is the most common question we get around here,” said Bill Schiering of Camera Security Now.

All CCTV Digital Video Recorders are Not Created Equally

DVRs are actually computers. They contain processors, memory and hard drives. All dvrs operate on some type of operating system like Microsoft Windows XP Professional. Cheaper units use cheaper operating systems such as embedded XP and Linux.

Some have more storage through the use of better software compression algorithms and larger physical hard drive storage space.

Functionally is the key limitation of cheaper CCTV DVRs. As you go down the evolutionary DVR food chain, fewer and fewer functions are available. Today’s top CCTV DVRs can allow users to view video at any internet connected location, including wireless! Yes, you can watch your cameras from Starbucks!

Component quality also comes into play. Cheaper units use cheaper parts like motherboards, video cards and processors. Do you really want your business to ride on the cheapest computer money can buy? You get what you pay for.

Customer service should also come into play. Do the people answer the phone? Are they knowledgeable about the product? When you call back during regular business hours, do you get a real person or a recording?

Lastly, consider the products that other security camera stores are selling in their estores. Do they have 1000s of incompatible products? Most do, we don’t. We only have the good stuff we know about.

Why buy our CCTV Security Camera DVR Surveillance System? Because we use top quality components, great compression utility, loads of hard drive video storage, we answer the phone, email and fax, we are knowledgeable about our product and we have installers nationwide or you can do it yourself.

Camera Security Now builds CCTV Security Camera DVR Surveillance Systems based on the following top technologies:

NEW RIOJA in last Monday’s edition published a safety report, and the decline in theft rates and fits in the province. On that note, talked about the possibility of the incorporation of security cameras in the downtown of the city.

In this regard, the Minister of Government, Security and Human Rights, Felipe Alvarez confirmed the information published by this newspaper.

As for the method to incorporate this technology, reported that it held through the SAPEM La Rioja Telecommunications, which has as a starter Javier Cobresí, while police will monitor the cameras.

“This will have benefits, because it decompresses the presence of police on the streets, and strengthen security at the periphery of the city,” admitted the official, who elaborated on the state policies that are made to lower rates theft and outbursts.

“Social policies are critical because they make the inclusion within the system, with opportunities for all. Since taking Luis Beder Herrera, the state has tended to actual policies of inclusion, equality, axes are education and production, accompanied by social policies “, determined Alvarez, who emphasized the 180 days of uninterrupted class equality of learning by providing laptops to all educational establishments in the province since the formation of SAPEM, “generated by this economic interaction, in this work generates genuine social inclusion”, found.

How does CCTV camera zoom work?

CCTV cameras are a great tool to monitor your home or workplace, preventing theft or intruders. The cameras are often equipped with different lenses for different purposes, depending on the size of the space being monitored and the positioning of the CCTV camera. Many CCTV cameras have zoom lens that are controlled either manually or remotely. A zoom lens provides a larger and more flexible angle, creating either a wide view or a zoomed view to get a closer look at a person or object.

1,Note the zoom range on the CCTV lens. This figure will tell you how far the lens can move between a wide angle and a zoomed-in view.

2,Observe as a CCTV camera with an attached lens zooms in on a subject. As the zoom level changes, you may notice parts of the lens rotating. The lens uses a small motor to move the glass components and zoom level further or closer to the focusing elements.

3,Listen as the CCTV zoom lens moves in or out, if you have an electronic lens.

4,Adjust the zoom level of the lens, if you have a manual zoom lens. As you twist the zoom control, the elements inside the lens are moving away from or closer to the focusing elements, changing the view you see on your screen.

1.Place the cameras in the areas you want to monitor. Cameras can be placed on any flat surfaces, or you may be able to mount them on the wall or ceiling, depending on your camera model. Plug each camera into an electrical outlet. Refer to your manual for additional installation instructions.

2.Plug your wireless router in and turn it on. Connect it to your modem using an Ethernet cable. Optionally, you may want to set up a security key for your wireless network, such as WEP or WPA password.

3.Insert the installation CD that came with your cameras, one by one, into your computer’s CD drive. Go through the install wizard to install the software for each camera on your computer. This software will be used to configure the wireless IP camera network.

4.Assign each camera an IP address on the network using the software installed for each camera. You can also create a login and password to restrict access to the cameras’ video feeds over the Internet.

Why is it so important to have DDNS support in IP camera?

If an IP camera can support DDNS (Dynamic Domain Name Server), users can set the IP camera at a virtual domain name (such as cam1.kitchen.Taipei.xxx.xxx) at dynamic IP, and be able to view this IP camera anywhere that has access to the internet. It saves money when setting up the broadband with service provider, whether it’s ADSL or cable modem, since fixed IP is not a must.

Some IP camera manufacturers claim to provide DDNS. However, they are software solution that needs to be installed at client site’s PC. Therefore, it requires users to see those IP cameras at the PCs that have installed the specific AP from manufacturers. This is not as user-friendly. Launch have DDNS function built-in the IP camera so that users can view the IP camera from anywhere.

What is PPP and PPPoE

Posted by on March 5, 2012 No comments

Point To Point Protocol (PPP) and Point To Point Protocol over Ethernet (PPPoE) are network protocols that allow data communication between two network entities or points. Throughout the documentation for both protocols, points are referred to as nodes, computers, or hosts. The protocols are similar in design with a major difference – PPPoE is encapsulated in Ethernet frames. Both protocols exist at the network access layer (also known as the data link layer) that supports network layer protocols including IPv4 and IPv6.

Point To Point Protocol (PPP)

PPP was first proposed as a standard by the Internet Engineering Task Force (IETF) in 1989 and became a working standard in 1994. The IETF specification for PPP is RFC 1661. PPP is a protocol most widely used by Internet service providers (ISPs) to enable dial up connections to the Internet. PPP facilitates the transmission of data packets between point to point links. Originally designed to work with serial connections, PPP was adopted by ISPs to provide dial up Internet access. PPP can be encapsulated in a number of data link layer protocols, including Ethernet (PPPoE) and Asynchronous Transfer Mode (PPPoA).

PPP uses Link Control Protocol (LCP) to establish a session between a user’s computer and an ISP. LCP is responsible for determining if the link is acceptable for data transmission. LCP packets are exchanged between multiple network points to determine link characteristics including device identity, packet size, and configuration errors.

PPP supports three types of user authentication protocols that provide varying levels of security. Password Authentication Protocol (PAP) is an access control protocol used to authenticate a user’s password on the network access server. The network access server requests a password from the client machine and sends the retrieved password to an authentication server for verification. As an authentication protocol, PAP is considered the least secure because the password is not encrypted in transmission.

Challenge Handshake Authentication Protocol (CHAP) is similar to PAP with several unique characteristics. Instead of requesting a password, the network access server sends a challenge message to the client machine. The challenge message is a random value. The client machine encrypts the challenge message with a user’s password and sends the combination back to the access server. The access server forwards the challenge/password combination to the authentication server. The authentication server encrypts the challenge with the user’s password stored in the authentication database. If the user’s response is a match, the password is considered authentic. CHAP uses the model of a shared secret (the user password) to authenticate the user. The use of CHAP is considered a moderately secure method of authentication.

Extensible Authentication Protocol (EAP) is considered an authentication framework used by a number of secure authentication protocols. EAP is most commonly used for authentication on wireless networks.

Point To Point Protocol over Ethernet (PPPoE)

The working standard for the PPPoE protocol was published by the IETF in 1999. The IETF specification for PPPoE is RFC 2516. PPPoE expands the original capability of PPP by allowing a virtual point to point connection over a multipoint Ethernet network architecture. PPPoE is a protocol that is widely used by ISPs to provision digital subscriber line (DSL) high speed Internet services, of which the most popular service is ADSL. The similarity between PPPoE and PPP has led to the widespread adoption of PPPoE as the preferred protocol for implementing high speed Internet access. Service providers can use the same authentication server for both PPP and PPPoE sessions, resulting in a cost savings. PPPoE uses standard methods of encryption, authentication, and compression specified by PPP.

PPPoE is configured as a point to point connection between two Ethernet ports. As a tunneling protocol, PPPoE is used as an effective foundation for the transport of IP packets at the network layer. IP is overlaid over a PPP connection and uses PPP as a virtual dial up connection between points on the network. From the user’s perspective, a PPPoE session is initiated by using connection software on the client machine or router. PPPoE session initiation involves the identification of the Media Access Control (MAC) address of the remote device. This process, also known as PPPoE discovery, involves the following steps:

1. Initiation – The client software sends a PPPoE Active Discovery Initiation (PADI) packet to the server to intitiate the session.
2. Offer – The server responds with a PPPoE Active Discovery Offer (PADO) packet.
3. Request – Upon receipt of the PADO packet, the client responds by sending a PPPoE Active Discovery Request (PADR) packet to the server.
4. Confirmation – Upon receipt of the PADR packet, the server responds by generating a unique ID for the PPP session and sends it in a PPPoE Active Discovery Session (PADS) confirmation packet to the client.

When a PPPoE session is initiated, the destination IP address is only used when the session is active. The IP address is released after the session is closed, allowing for efficient re-use of IP addresses.
