  • Low-Light/Bright or Both

The level of light depends on the area where you have planned to fix the camera, and it helps you to make a better choice. If the place where you have to film is bright, then your camera choice may be limitless as many HD-Surveillance cams operate in high ambient light. Indoor areas have a more stable environment where light can be easily manipulated.

However, the low light requires additional considerations that can limit your camera choice because not all HD-Surveillance cameras support low levels of light.

If you have planned to mount your camera at a place with a low level of light, then make sure to find a camera with a light sensitivity rating of 1-Lux or lower. Most probably, it will be labeled as a “Day & Night” camera or will be featured as a little light compatible camera. Day/Night cameras are most flexible and allow you to monitor an area accurately. They work better in all light conditions.

For those who want to set a camera outside of their home, this is very beneficial for them to buy a Day/Night HD-Surveillance camera.

  • Indoor/Outdoor

The level of light has a high impact on your camera requirement, and as mentioned above, a Day/Night camera is a primary choice, but not all Day/Night cams will meet your required need.

The weather conditions also play a hefty role: wind gusts, rain, snow, temperature, and UV rays.

A camera that is initially designed for indoor monitoring may not be suitable to set outside as it can not bear the harsh conditions of weather. Outdoor cameras come with extra ability to withstand the brutal pounding of outdoors. These HD-Surveillance cameras are typically made to last longer.

When finding an outdoor camera, you must search with features like water resistance, temperature, and humidity bearing power.

  • Wireless or Wired

You will need to choose between wired or wireless surveillance cameras. Wired cams are more proficient in sending high-quality footage as they transfer the data through a wire.

On the other hand, wireless cameras can be fixed virtually anywhere without requiring a wire and an installer to transfer the data. The notable thing is that some wireless camera requires a clear line to transmit the signals correctly.

It means there can not be so many obstacles between the camera and the receiver, or the picture may not be transferred appropriately. In comparison, a wired camera system installation will cost you a little higher.

  • Fixed or PTZ

A fixed view camera or the one that can monitor different angles and cover more area through a panoramic view; it depends on your preference. If you need to include a specific place like a driveway, walkway, or door, then a single view camera will work excellent here. But if you prefer to cover a more extensive range, then the PTZ remotely-swivel camera will be the best choice, and it will allow you to zoom footage more than the fixed cam.

  • Infrared-Cameras

Infrared cameras come with LEDs around the lens that allows a person to look clear footage in harsh weather conditions or darkness. Almost all modern camera manufacturers have introduced this feature. The only factor that needs attention is to check quality. If you want to dig up more into the object, then infrared cameras are considered best for identifying an object in the dark.

  • Power-Back-Up

It is essential to keep a back-up for your surveillance cams. Just in case if your power disconnected for a reason like disasters, etc. A battery with 1000-VA will be enough back up to keep working your camera uninterrupted. The power back-up must be connected with the camera and the DVR, so the ability of your camera to record the footage will not be hindered.

Connecting a back-up is not necessary, but it will allow your surveillance system to run smoothly without being compromised.


Surveillance cameras are imperative for any business or home. Installing an HD-surveillance camera secure your assets more proficiently. No one will prefer a camera with low quality as you can not identify the object, and the zoom capability will be limited as well. The best security camera must have a high resolution, higher frame rate, light adjustments, audio clearness, storage capacity, and a night vision features. There are several other options like wired or wireless, indoor/outdoor, surveillance cams. List up your preferences and requirements and then find the best fit that fulfills your needs.
