Decisions, Decisions, Decisions...

There are hundreds of camera models available for your security application and if you're new to industry the decisions can be too much. Here we are here to give a brief overview of some camera types to help you choose the right security camera for your application. Be it for a home or business install, it's all about knowing what conditions warrant a specific type of camera. There are several types of security cameras Bullet, Domes, Fixed or Box, Hidden, IP and Infrared are some. They come in color or black and white output. Generally black and white cameras need less light to show a picture, so if you have a low-light situation a black and white camera would be a reasonable choice if you are on a budget.

Most security cameras are used as the name suggests: for security purposes. They can be used for crime deterrence or monitoring. For example, retail stores usually have a big monitor showing some random video from their store or showing you walking in the front door. They do that to let the thieves know in advance that they are actively looking out the shrinkage - a fancy retail word for theft of inventory. 

Although cameras have long been used the business security world, they are becoming an option for residential security too. Home owners are installing cameras in and around their homes. Security camera manufactures have not taken a proactive approach about modifying their designs for the residential market, but once the market grows and they see it's in their best interest, they will design more pleasing camera models that will blend into a residential setting nicely. Until then, you'll have to make due with what they are currently offering.

The CCTV surveillance industry is like other industries whose product relies on electronics. There is a price-to-quality ratio and, in most cases, you do get what you pay for. Sites, such as Ebay offer hundreds of cheap mass produced cameras on sale for $25 dollars or less. Be mindful that although these camera will work,  they probably won't work for an extended amount of time - remember a security camera has to be on duty 24/7 - or the will not show a decent picture, or both. I've had professional cameras that only lasted a couple of months due to a bad circuit board; but I was secure in the knowledge that I bought a reputable brand that offered a 3 to 5 year replacement warranty.

Security cameras are generally powered by 12DC, 24V AC or some models are equipped to handle either power source.
