Turn your head in any direction and I am sure that you will find at least one security camera located in a corner out of common view. These surveillance cameras are used almost everywhere, from malls, office and streets to homes. In terms of security and video surveillance, these cameras are great in capturing crucial footage that may be viewed later and also used as evidence.
Before you get security cameras for yourself, make sure you consider the following things.
- Will the camera be used indoors or outdoors?
If you need an outdoor camera, you would need one that is waterproof. You can ask the manufacturer or read the specifications of the product to find out. Indoor cameras do not have to be waterproof necessarily, but you get one if you need it.
- Is there adequate lighting throughout the day?
Some cameras have IR (infra-red) technology integrated in them which allows them to get adequate lighting without affecting the view for humans. You would not even know if the rays were being emitted as they are not visible at all. If you are still wondering how it works, check out night vision goggles. They work pretty much the same way. IR enabled security cameras are great for monitoring areas that do not have the required lighting throughout the day.
Day and night cameras are also good for use in low lighting conditions. These cameras shift to black and white in low lighting to capture videos with greater clarity. When the lighting is appropriate, the cameras function normally. You may choose between a Day & Night Camera and an IR enabled camera as per your requirement.
- What is the video quality that you are looking for?
If you want to check the recording or video quality of a security camera, check the TVL number. TVL stands for TV lines and is a measurement of a camera’s horizontal resolution. For example, a camera with a TVL value of 480 will have 400 lines of horizontal resolution. Higher TVL values are always better. In order to understand the quality levels in relation to the TVL value, check out the following reference.
- Low Resolution – 350 TVL
- Mid Resolution – 480 TVL
- High Resolution – 540 TVL – 60 TVL
- Do you need audio recording as well?
Most security cameras do not record audio. So if you need audio recorded, make sure you check the specifications of the camera before buying it.
- Should I buy a Wired Camera or a Wireless Camera?
Wired security cameras transmit a more solid and secure video signal due to the transmission being done through cables. But this may not be the most budget-friendly option. You would need to buy the required length of cables and hire an installer to get the job done if you are not able to do it yourself. Wireless Security Camera System can be placed anywhere without worrying about connectivity issues. The risks to the signal’s security do exist, but they are being overcome to a considerable extent with the use of transmission protocols such as Wi-Fi Protected Access (WPA) and Temporal Key Integrity Protocol (TKIP).
- Should I opt for a fixed or a PTZ security camera?
If you plan to keep the camera fixated on one specific view, then you should go for a fixed security camera. But if you need the camera to remotely swivel and at times zoom in to get a closer view, then a PTZ (Pan-Tilt-Zoom) camera would be a better choice.
Types of Security Cameras
It is important to understand the different types of security cameras that are available and their unique characteristics. By understanding the features of the different security camera types, it would be easier for you to make up your mind.

This particular camera is versatile in terms of applications because it has high flexibility. Business owners as well as home owners find this highly useful even though this camera is a basic yet cost effective surveillance device. Don’t worry if the camera does not fit comfortably in the desired spot. Casings can be purchased to suit different applications. Waterproof casings allow brick cameras to be used in an outdoor setting. If you are not happy with the camera resolution, you can always buy lenses separately to suit your need.
Dome cameras do not grab a lot of attention and this makes them perfect for use in video surveillance. This type of camera is popular with retail stores, hotels and offices. But you can use it in your home as well. They don’t take up a lot of space and due to their minimalistic design. You will usually find these cameras mounted on the wall. However, if the camera has a 3 axis gimbal, the camera mount can be rotated on the wall itself. The best thing about these cameras is that infrared bullets can be added to capture videos even in low light settings.
IR Bullet Camera
The IR bullet cameras are good for indoor and outdoor use. These cameras come in a weather resistant casing. The cover on top of the camera is required for reducing solar glare. The infrared LEDs turn on automatically in low light conditions, so you don’t have to worry about keeping these cameras active 24×7.
