4MP Wifi Cameras

Buy 4MP WiFi CCTV Cameras for Detailed Coverage
A 4MP WiFi CCTV camera provides higher pixel detail than 2MP options and can suit entrances, counters, larger rooms and selected outdoor areas. Available models may include fixed, dual-lens or pan-tilt designs. Check the exact lens, lighting performance, power method and app features before choosing.
Higher resolution can increase WiFi bandwidth and storage use. Test the wireless connection at the intended position and confirm the supported network band. Most models still require a power adapter even though video is transmitted wirelessly.
Features to Check Before Buying

Lens and target distance: a wide view covers more area but places fewer pixels on distant subjects.
Pan-tilt or dual view: verify movement, tracking and how simultaneous views are recorded.
Storage: check microSD limit, bitrate, codec, overwrite and cloud subscription options.
Night image: compare IR range, supplemental light and available ambient lighting.
App security: use strong credentials, review shared users and keep firmware current.
Outdoor use: confirm weather rating and protect the electrical connection.

Should You Choose 4MP WiFi?
Choose 4MP when the scene and mounting position can use the added detail and the network can carry the bitrate. A 2MP WiFi camera may be enough for a smaller room, while a 3MP model provides a middle option. Compare the complete WiFi CCTV camera range.
Retention depends on resolution, bitrate and recording schedule; use our CCTV storage guide for general planning, noting that standalone camera storage limits differ. If WiFi is unavailable, see 4G SIM CCTV cameras.
