WiFi Camera Data and Electricity Use: Monthly Cost

A home WiFi camera costs very little to run. Recording to an SD card uses almost no internet data, live viewing uses roughly 225 MB to 900 MB per hour depending on quality, and the camera itself typically draws 3-6 watts, which is about 2-4 units of electricity a month, or roughly ₹10-₹40 at common tariffs. The numbers below are illustrative; your camera's resolution, app settings and state tariff change them.

Where the data goes

A WiFi camera, such as one used with the V380 Pro app, sends data over the internet only in three situations:

1. Live view: you open the app and watch the camera.
2. Playback: you watch recordings stored on the camera's SD card from your phone.
3. Cloud upload: if you pay for cloud storage, the camera uploads clips continuously or on motion.

If none of these happen, the camera stays connected to the app's servers with a small amount of background traffic and records to the card locally. That background traffic is small compared with video.

Bitrate: the number that decides everything

Video data is measured as bitrate in megabits per second (Mbps). For typical home WiFi cameras, a stream of roughly 0.5 to 2 Mbps is common, lower in "SD/smooth" mode and higher in "HD" mode.

Conversion: 1 Mbps for one hour = 1 ÷ 8 × 3,600 = 450 MB.

Switching the app to a lower quality while on mobile data is the simplest way to save data.

Worked example 1: a household checking the camera daily

A family checks their camera on mobile data for 20 minutes a day in HD (1 Mbps) and plays back recordings for 10 minutes a day.

• Live view: 20 min × 7.5 MB per minute = 150 MB
• Playback: 10 min × 7.5 MB per minute = 75 MB
• Per day: 225 MB
• Per month (30 days): 6.75 GB

On a 1.5 GB/day mobile plan, 225 MB is about 15% of the daily allowance. The camera side also sends the same 6.75 GB a month over home broadband, which unlimited fibre plans absorb without noticing.

If the same family watches in SD (0.5 Mbps), the monthly total halves to about 3.4 GB.

Worked example 2: cloud upload

Cloud plans keep sending video from your home connection whether you watch or not.

Continuous cloud upload is significant on a capped broadband plan, and many plans have a fair-usage limit even when sold as "unlimited". Check your plan before choosing continuous cloud recording. For the cost of the cloud subscription itself, compare it with an SD card before buying.

Electricity: watts to units to rupees

Most indoor WiFi cameras run from a small 5V adapter. Typical draw is about 3-6 watts, rising a little at night when infrared LEDs turn on and briefly when a pan-tilt motor moves. Outdoor cameras with floodlights or larger IR arrays can draw more; check the adapter rating or manual.

Units (kWh) per month = watts × 24 hours × 30 days ÷ 1,000.

Tariffs differ by state, slab and fixed charges, so use the per-unit rate on your own electricity bill. A camera's few units rarely push you into a higher slab on its own, but the WiFi router must also stay on 24x7; a typical home router uses a similar order of power, roughly 5-10 watts.

Worked example 3: total monthly cost of a two-camera home

Assumptions: two cameras at 5 W each, router at 8 W, ₹7 per unit, unlimited broadband already in use, viewing as in example 1 on a mobile plan you already pay for.

• Cameras: 2 × 3.6 units = 7.2 units
• Router: 8 × 24 × 30 ÷ 1,000 = 5.76 units (you would likely run it anyway)
• Electricity for cameras only: 7.2 × ₹7 = ₹50.40 a month
• Including the router: (7.2 + 5.76) × ₹7 = 12.96 × ₹7 = ₹90.72 a month
• Data: covered by existing plans, ₹0 extra unless you exceed limits

Over a year, the cameras add roughly ₹600 to your electricity bill. Add any cloud plan and SD card replacement to get the full running cost. If you track household bills, note these small recurring costs alongside the rest; see how to track monthly expenses.

Scaling up: four cameras in a shop

A small shop with four cameras, each at 5 W, recording to SD cards with the owner checking two cameras for 30 minutes a day in HD:

Commercial electricity tariffs are often higher than domestic ones, so use the rate on your shop's bill. Upload bandwidth matters only when several streams are viewed at once or when cameras upload to the cloud; a 2 Mbps peak is well within typical fibre plans, but on a slow DSL or 4G router it can cause stutter.

Power cuts and inverters

Cameras stop recording when the power goes, which is exactly when some thefts happen. On an inverter or UPS, a 5 W camera plus an 8 W router is only about 13 W, so a home inverter supports them for many hours. A small DC UPS meant for routers is another option if the camera uses a compatible adapter; check voltage and connector first.

Ways to cut data and power use

• Watch live in SD or "smooth" mode on mobile data; switch to HD only when you need detail.
• Use motion recording instead of continuous where it suits you, which also lengthens SD card life.
• Prefer event-based cloud over continuous cloud on capped connections.
• Turn off indoor cameras when the family is home, if you only need them while away. This also helps privacy.
• Check your broadband's fair-usage limit if you add several cameras with cloud upload.

Menu names for video quality and recording mode can differ slightly by app version.

Recurring small charges such as cloud plans and data top-ups add up across a year; our guide to tracking subscriptions and bills keeps them in one list.

Key takeaways

• Recording to an SD card uses almost no internet data; viewing and cloud upload do.
• At an illustrative 1 Mbps, video uses about 450 MB per hour; 20 minutes of daily viewing is about 150 MB.
• Continuous cloud upload at 1 Mbps is around 324 GB a month, so check broadband limits.
• A 5 W camera uses about 3.6 units a month, roughly ₹25 at ₹7 per unit.
• Use your own bill's per-unit rate and your camera's actual settings for exact figures.
