In this guide I want to answer the questions I get most often from Bali villa owners considering CCTV: how many cameras do I need, what resolution actually matters, how much storage do I need, and can I really watch my cameras from overseas. The answers are more practical and specific than most of what's written about CCTV online, which is usually either too generic or trying to upsell maximum specifications.
How Many Cameras for a Bali Villa?
Most standard Bali villas — 2 to 4 bedrooms on a single plot — are adequately covered by 4 cameras: main entrance/gate, villa entrance door, pool area, and carport or parking area. These four positions cover the primary access and value-area surveillance requirements.
For larger villas with multiple buildings, guest villas, or complex garden layouts, 6–8 cameras may be needed. For villas where interior monitoring (lobby, common areas) is required alongside perimeter coverage, add 1–2 indoor dome cameras.
More cameras isn't always better. Cameras that are poorly positioned, have low-quality optics, or aren't correctly aimed provide less useful coverage than fewer well-positioned cameras.
Resolution: What Actually Matters
For identification of individuals and vehicle plates in Bali's typical villa camera scenarios, 1080p (2MP) is the practical minimum and 4MP (2K) is the practical sweet spot. 4K cameras produce larger files and require more storage without providing proportionally more useful information at typical Bali villa camera distances (5–15 metres).
Resolution is less important than lens selection. A 4MP camera with the wrong focal length for the distance — providing an image that's zoomed in too tight or too wide for the capture distance — is less useful than a 2MP camera with the correct lens.
How Much Storage Do I Need?
For a 4-camera system at 1080p recording continuously 24/7: approximately 80–100GB per day. A 2TB hard drive provides approximately 20 days of retention. A 4TB drive provides 40 days. Most Bali villa owners find 15–30 days of retention sufficient for their purposes — long enough to identify an incident after the fact, short enough that storage costs are reasonable.
Remote View: What to Expect
Modern Dahua and Hikvision IP systems stream remote live video at 1–3 Mbps per camera — requiring 4–12 Mbps upload speed from the Bali internet connection for 4 cameras streaming simultaneously. Bali's IndiHome residential fibre typically provides 10–20 Mbps upload, which is adequate. Mobile data (4G/LTE) at the villa location is the consideration — remote areas may have insufficient upload speed for smooth multi-camera streaming.
Where to Place Cameras
Placement matters more than camera count. The four positions that earn their place on almost every Bali villa are the main gate (faces and vehicle plates arriving), the villa entrance door, the pool and terrace (safety and the most common dispute zone for rentals), and the carport or parking area. From there, add coverage for any secondary access point — a beach gate, a service entrance, a back lane. Mount cameras high enough to be out of easy reach but angled down enough to capture faces rather than the tops of heads, and avoid pointing straight into the afternoon sun, which silhouettes everyone who walks toward the lens.
What CCTV Costs in Bali
As a rough guide, a four-camera IP system supplied and installed with cabling runs roughly IDR 5,000,000–9,000,000, and an eight-camera system IDR 9,000,000–16,000,000. If you have intact coax from an older system, an HD upgrade reusing that cable is considerably cheaper. The variables that move the price are camera resolution, the length and difficulty of the cable runs, and how much recording retention you want, since that drives the hard-drive size. Our pricing page lists current guide ranges for common jobs.
Maintenance You Should Plan For
One point that surprises owners coming from cooler climates: Bali is hard on cameras. Salt air corrodes mounts near the coast, tropical dust and salt film coat lenses within months, and NVR hard drives run hot and wear faster than the manufacturer's rated life. A system that records perfectly at handover can be producing noticeably worse footage eighteen months later if it is never serviced. Budget for an annual maintenance visit to clean lenses, re-aim drifted cameras, and replace ageing drives before they fail — it is far cheaper than discovering a blind or blank system at the exact moment you need the footage.
