You are ready to install a security surveillance system in your business, but find yourself a little overwhelmed by all of the different options. Analog or IP? What does it all mean? There are many advantages and disadvantages to each style of camera, so here are a few key points to help you decide which camera is best for your business, and your budget.
The primary difference between the two camera types is the way the video signal is delivered. Analog cameras turn the video signal into a format that can be received by a television or another receiver, like a VCR. In contrast, an IP based camera (which typically utilizes HD cameras) digitizes the video signal using a specialized encoder; this allows the captured video images to be viewed not only through an existing network but also from a web browser that can be accessed through the Internet. However, both analog and IP-based video cameras can transmit signals either wirelessly or through wired connections such as Cat-5 cables.
PROS of analog cameras
• Lower cost
• Larger variety of designs — If you have specific surveillance needs you may find it easier to find the style of camera you need (mini dome, larger and mounted etc.) with an analog model.
• High compatibility to mix and match cameras and brands. This can make it easier if you already have existing camera equipment that you wish to incorporate into your surveillance system.
CONS of analog cameras
• Lack certain advanced features such as digital zoom.
• Potential interference problems — If you are installing a wireless surveillance system, analog systems can have interference problems. More importantly, the resulting signals cannot be encrypted which potentially means someone else can view the signal.
• Large jobs are more difficult — Analog cameras generally do not accommodate big distances, and getting them to work over broad ranges can be difficult.
PROS of IP cameras
• Better wireless reception – IP cameras have encryption built right into them providing for a more secure network.
• Can utilize existing wiring – Because IP-based cameras act as their own network device, you can often take advantage of existing network wiring within your premise, making the installation task much easier.
• Better suited for remote access.
• Higher quality video film – Excellent digital zoom allows for clear imaging in the event you must rely on surveillance footage for proof of criminal activity.
CONS of IP cameras
• Higher cost — Because of the additional technology that is built into each camera, the cost is generally higher than analog cameras.
• Higher bandwidth required.
Given the pros and cost of each camera type, the decision truly comes down to your specific surveillance needs; so take a minute to think about it carefully. For example, if you are a bank or convenience store, it may be worth the extra upfront cost to purchase IP cameras that capture clear images with digital zoom. (Think of how nice it would be to finally catch the elusive Geezer Bandit who authorities still are not sure if it is an old man, or just a man in a mask.) Yet, if you are a small salon with basic security needs, IP cameras may be more than you require. No one will know better than yourself.
