Technical features to consider

Resolution

Higher resolution means clearer images.

Options include:

• 1080p

• 2K

• 4K

Higher resolution is ideal for identifying faces and number plates.

Field of view

Measured in degrees; wider angles reduce the number of cameras needed.

Night vision

Choose between:

• Infrared (IR) night vision

• Color night vision (requires ambient light)

Motion detection

Useful for triggering alerts and saving storage space.

Two-way audio

Helps communicate with visitors, delivery personnel, or intruders.

Weather resistance

Outdoor cameras must be rated IP65, IP66, or IP67.

Storage options

• Local NVR/DVR

• Cloud storage

• SD card

Each has different costs and security benefits.

Internet and Network Requirements

For modern security setups, strong Wi-Fi and internet speed are essential. This is one of the biggest points under What to Know Before Security Camera Installation?, especially for wireless and cloud-based cameras.

Network tips
